Apprehensive about a burning smell from your furnace? Call Quality Heating, Cooling & Plumbing today at (918) 212-0122 to get to the bottom of the issue!

Every year once winter hits, homeowners flip a switch on their thermostat to turn on their heat. This heat keeps homes warm, cozy, and comfortable throughout the cold winter months. 

Without a working furnace, your home may get too frigid. Dangerously cold temperatures can damage your home’s plumbing and piping work, creating an unsafe environment for residents. 

After switching on the furnace, some homeowners notice a burning smell. While some burning smells from the furnace are common and harmless, others are not.

Don’t leave your and your loved ones’ safety to chance. Contact Tulsa’s HVAC installation experts from Quality Heating, Cooling & Plumbing to investigate the burning smell and assess your HVAC needs.

Is a Burning Smell from Your Furnace Normal?

If you notice a burning smell coming from your furnace, it’s not always something hazardous. But understandably, homeowners worry when they smell any fume in their home, whether harmless or not. 

One reason your furnace is exuding a smell is because it’s running for the first time in months. When your furnace sits without use, it collects dust and grime on the interior heat exchanger, burners, and exterior. When you turn it back on for the winter, these components may burn off, causing an odor.

If you notice a strange smell only during your first couple hours of using your furnace, it’s most likely not a cause for concern. If you’re still wary, call a professional HVAC team to investigate the cause. 

Why Do Furnaces Create Burning Smells?

The range of reasons why furnaces create burning smells is quite broad. Some of the causes include but are not limited to:

• Clogged air filters
• Underlying electrical issues
• Build-up on internal furnace components
• Wear and tear of wires and electrical parts
• Gas leaks

Without professional intervention, there’s no way to know what is causing your furnace’s burning smell. Reach out to our skilled HVAC technicians to ensure you find and resolve the correct source of the problem.

Two Common Smells and What They Indicate

Many sources may cause a burning smell from your furnace. Continue reading for more details on specific scents you may encounter and what they could indicate about your HVAC system.

Dust Smell

If you experience a dusty odor after running your furnace, the smell may mean one of two things. The first is that layers of settled dust particles are burning off the components of your furnace. If you have this situation, the smell should go away after running the furnace for an hour or so.

The second may indicate your air filter needs cleaning or changing. When dust, mildew, and other impurities pile on your furnace’s filter, they clog it. When your furnace tries to push air through this filter, it may create a musty smell or cause respiratory symptoms among those in your household.

Plastic Smell

If you notice a plastic or chemical smell coming from your furnace, something may be burning in it or the furnace contains a foreign object. These objects could be anything from a water bottle, a plastic cap, or a toy. 

This scent permeates the home quickly, and it’s toxic to breathe. If you see something in the furnace, hire an HVAC technician to remove the object if it’s hot or lodged in a place where removal may cause damage.

Smells That Indicate an Emergency

Some burning smells are harmless, while others point to the need for emergency repair. Read on to learn about the odors that warrant immediate attention.

Egg Odor

An egg or sulfur odor may indicate a gas leak. Most of the time, natural gas has an added chemical that smells like rotten eggs.

This additive can prove helpful if you have a leak. Homeowners can detect a leak because the natural gas odor is typically undetectable to the human nose.

Immediately turn off the unit if you detect a rotten egg odor near your furnace. It’s also a good idea to open windows throughout the home to let fresh air dissipate the gas. If the gas levels are high, you must call your gas provider and leave your home until professionals say it is safe.

Once you’re cleared to reenter your home, call Quality Heating, Cooling & Plumbing. We’ll deliver efficient servicing to get the repairs you require. 

Electrical Odor

Another odor to watch out for is an electric smell. Some describe this scent as metallic and smoky. This odor may indicate burning wires, failing furnace components, and overheating. 

This smell could also mean that safety features aren’t working correctly. To prevent fire hazards, enlist the help of heating and cooling professionals to complete repairs. At Quality Heating, Cooling & Plumbing, we’ll ensure your system functions perfectly while adhering to safety protocols. 

Always Follow Up with an HVAC Professional

Regardless of whether the burning smell dissipates, it’s a wise idea to consult with trained HVAC technicians. This way, you can rest easy knowing your furnace and any odor from it isn’t a hazard. 

You should also note that HVAC units are complex systems with many working parts. They’re not meant for repairs from amateurs. Instead, they require restorations, maintenance, and servicing from trained, certified, and licensed professionals.

By opting for annual maintenance, professional installations, and repairs, you’ll keep your furnace working properly and protect your loved ones.

Quality Heating, Cooling & Plumbing can help you with the proper AC placement. Tulsa, OK, residents can call us today at 918-212-0122! 

Many factors should influence the type of air conditioning units you buy and how you use them. For example, many homeowners may think of elements like an AC unit’s size, energy efficiency, cost, etc. However, another factor people need to think about is AC placement.

Choosing the proper location proves essential for any HVAC system, whether a heat pump condenser, split air conditioner, or another unit. You’ll situate most systems indoors, including air handlers and furnaces. Indoor placements allow these appliances to access your ductwork and vents.

However, your air conditioner’s compressor or condenser unit has vastly different needs. This guide will explore where you should place your AC unit and why this location makes a difference. You may also require an expert from Tulsa’s AC repair service.

Where Should You Place Your Air Conditioning Unit? 

Depending upon the type of air conditioner you have, you may have indoor and outdoor units. However, homeowners should never install an AC unit’s condenser indoors, like in their attic, basement, or crawlspace.

You should place your AC unit’s condenser outdoors due to your system’s evaporator coil. Your evaporator coil extracts heat from your home, and your condenser works to release this hot air.

If you install this unit indoors, this captured heat will disperse throughout your home’s floors, ceilings, and every room. Essentially, doing this will defeat your air conditioner’s primary purpose.

An improper AC placement also forces your unit to run prolonged cycles. These lengthy cycles attempt to battle the extra heat, resulting in higher energy bills. You also risk wearing down your unit’s crucial components more quickly.

Depending on your model, you can expect your air conditioner to last between 15 and 20 years. However, this lifespan stems from proper maintenance and installation. Worn-down parts and higher operating costs can significantly cut down on this lifespan.

Your AC unit’s condenser also needs vast fresh air volumes to spread heat sources properly. Unfortunately, spaces like basements and attics don’t provide enough area for suitable air circulation.

Does It Matter Where You Place Your AC Unit Outside? 

You now know you need to place your AC unit’s condenser outside. However, your follow-up question might be if it matters where exactly you put this outdoor unit.

You’ll want to find a covered or shady spot for the best results. These types of areas will optimize your unit’s energy efficiency. A shady or well-covered spot prevents your unit from using too much energy to convert temperatures before sending it back into your house.

Your hot condenser coil will spread extracted heat sources more efficiently when you place it in a cooler environment. A level surface that sees the least amount of sunlight is ideal.

However, one other consideration to have in mind is not to place your AC unit close to overgrowing foliage. This overgrowing foliage can quickly clog your unit’s filters. If you decide to place your AC near vegetation or hedges, regularly trim them.

Should Other Factors Influence Your AC Placement? 

A few other factors may influence the AC placement that you should take into consideration. For example, most homeowners prefer placing an AC unit far away from a space with a lot of activity.

Although air conditioners are becoming quieter, some can still make plenty of noise, especially when working overdrive on a hot, humid summer day. HVAC technicians can help pinpoint the best locations to place your AC unit.

Creative Ways To “Hide” Your AC Unit 

The best AC location for energy efficiency might not be the best for aesthetics. However, you can have the best of both worlds instead of trying to compromise one for the other. Let’s examine four creative ways to hide your AC unit:

1. A Dedicated Space 

If you have many outdoor items like lawnmowers, pool supplies, garden hoses, etc., you can create a dedicated space to store them.

A small shed built on the side of your house can be a great place to store these items alongside your air conditioner. Just ensure it has plenty of ventilation.

2. Vegetation and Structural Screens 

Placing your AC unit on your patio provides another method you can try. A customized cover for your unit might be outside of some homeowners’ budgets. Plant screens, on the other hand, provide a budget-friendly alternative.

You can also incorporate a garden filled with climbing plants to add a vertical twist.

3. Fence Your Air Conditioner In 

Fencing your air conditioner offers a simple option for concealing it. However, for a next-level design, you’ll want your fenced-in air conditioner to blend with the rest of the area.

4. Find Ways To Distract Viewers 

You can find many creative ways to distract viewers from looking at your air conditioner. For example, have a gorgeous garden with a customized walkway, beautiful vegetation, and maybe even a waterfall.

With all these features present, no one will look at the air conditioner stashed away in the corner.

What Other Factors Matter Besides Placement? 

Besides AC placement, plenty of other factors matter, including:

The Cost

Of course, your budget will significantly impact the AC unit you buy. However, you shouldn’t just buy the cheapest model available as they’re often not as energy efficient. Likewise, the most expensive unit may not be practical for your home’s needs.

The Size 

For your home or business, you want the right-sized air conditioner. HVAC technicians can help you choose the correct size.

Overall Quality 

Some AC units offer greater durability, last longer, and provide better energy efficiency than others. High-quality systems can slash your energy bills, and you won’t need to maintain or repair them as often.

To diagnose and fix a knocking sound in furnace vents, call Quality Heating, Cooling & Plumbing at (918) 212-0122! 

By design, a properly functioning furnace should heat without making too much noise. Hearing a furnace vent knocking sound is rarely a good sign. Causes can range from cold weather, poor installation, damaged parts, and more.

Homeowners shouldn’t panic if they hear strange noises from their furnaces. However, they also should pay attention to these noises as they can indicate serious problems.

This blog will explore common reasons why your furnace makes a knocking sound and when to call Tulsa’s heating and cooling experts.

Reasons Why Your Furnace Is Making Sounds 

Homeowners will find a multitude of reasons why their furnace makes a knocking or rattling noise:

Cold Weather Is Stressing Out Your Furnace 

Naturally, homeowners use their furnaces more during winter. During winter, your furnace assumes enormous responsibility and works harder, especially if you haven’t turned it on in a long time.

This extra effort can cause your furnace to create a knocking sound. While the sound can be a nuisance, it isn’t something to worry about, especially when battling low temperatures.

How Can You Tell That Cold Weather Is the Problem? 

The problem with attributing cold weather to a knocking sound in furnace vents stems from the fact that you use your furnace the most during winter. As such, winter becomes the time you will most likely experience issues.

You may hear strange noises upon turning on your furnace, but they go away after a few minutes. In this case, you can likely blame the cold weather. However, if knocking persists, you may have a more significant issue on your hands.

You Have a Dirty Blower Wheel 

A filthy blower wheel can make it unbalanced. In the worst scenario, an unbalanced blower wheel may even explode. Not regularly maintaining your blower wheel leads to this imbalance.

Maintaining your blower wheel is an easy fix that many homeowners can handle. Replace your furnace air filters regularly, as they can quickly suffer from buildups from dirt, debris, pet dander, etc. All this grime causes an imbalanced blower wheel that’ll eventually break.

Our experts recommend you replace your furnace filter at least once every three months. However, you may need to replace your filter sooner. For example, we recommend pet owners replace their filters once a month.

Cleaning Your Permanent Air Filter 

Instead of disposable air filters, some homeowners may have a permanent air filter. A permanent air filter can translate into massive savings, but you must know how to clean one properly. You’ll need filtered water, mild dish soap, and a spray-on cleaner.

Soak your filter in your solution, then rinse off using your filtered water. Depending on how much dirt and grime, you may need to repeat this process several times.

You can let your permanent filter air-dry, but you won’t cause harm by placing it back inside your furnace immediately.

Your Air Ducts Are Striking the Walls 

Inside your air ducts, two processes occur—contraction and expansion. As temperatures rise, your air ducts’ metal parts heat up. These parts will then move around, producing a knocking sound in furnace vents.

Fortunately, this is entirely normal and generally doesn’t signal an issue.

How Can You Tell Your Air Ducts Are Causing the Noise? 

Like cold weather, a knocking sound caused by air ducts occurs when you first turn on your furnace. However, a knocking sound caused by air ducts can also appear when your system stops blowing warm air.

While noisy return ducts generally aren’t a cause for concern, they can indicate poor installation. An expert HVAC technician can inspect your system and make adjustments to kill the noise.

Your Fan Belt Is Hitting Other Components 

A broken or cracked fan belt will strike your furnace’s metal parts as it rotates. Therefore, you must replace a cracked or broken fan belt when you identify the problem. Doing so will prevent harm to other crucial parts.

Identifying a Broken or Cracked Fan Belt 

The first way to identify a cracked or broken fan belt includes removing your furnace panel. However, you can also identify this issue by carefully listening.

A knocking sound in furnace vents from a broken fan belt has a distinctive pattern. You probably have a broken fan belt if you can easily predict when the subsequent knocking occurs.

Can You Fix a Fan Belt Yourself? 

For some homeowners, a broken part allows them to test their DIY skills. However, repairing a broken fan belt requires a specialized touch. It’s better to call a professional HVAC technician to avoid further damage.

Ways To Help Choose the Right HVAC Technician for the Job 

Whether dealing with dirty burners, exploring open versus closed vents, or diagnosing why you hear a knocking sound in furnace vents, you need to hire the right team. The following steps can help you make your selection:

Do Ample Research 

While online reviews can be a great start, referrals from trusted sources often carry a higher weight. You should also check a contractor or company’s website and social media pages. Look for the following elements:

• Their qualifications
• A licensed, insured, and bonded company
• Their core values
• What types of clients do they serve
• If they specialize in any areas
• Testimonials

Request an Estimate

Many HVAC repair companies provide a free estimate. State your problem and ask them how much the service will cost, alongside an average timeframe.

An On-site Visit and Consultation 

Finally, your HVAC repair technician will visit your home or business and inspect your system. Once they diagnose the issue, they may need to adjust the initial estimate. Once you agree with the price, they can start working or schedule a future time.

HVAC systems are some of the most crucial parts of any home or office space. Without HVAC systems, we would never enjoy the comforts of indoor cooling and heating. HVAC functioning is essential during certain seasons to offset extreme outdoor temperatures.

Property owners usually don’t consider the electrical requirements for HVAC systems when building or renovating a new home or office. However, running an HVAC system on faulty electrical components could severely damage it. Finding reliable HVAC installation in Tulsa to service your repair and electrical needs is crucial to maintaining a healthy system.

Electrical Systems Support Your HVAC Functioning

Many home and business owners don’t realize how crucial their electrical equipment is to HVAC functioning. HVAC systems have significant components in almost every part of your property, giving it the power to cool and heat your entire home or office. These components all require electrical power, which is the lifeblood of your HVAC system.

Like any electrically supported appliance, the size and power of your HVAC system will also determine your electrical needs. A wall or window unit with only one vent will have drastically different requirements than a multi-duct or split-system HVAC unit. Therefore, understanding how electrical systems support your HVAC unit limits problems with tripped breakers and electrical system breakdowns.

Key Electrical Considerations for New and Existing HVAC Systems

Review some key electrical considerations if you’re having problems with an existing unit or considering installing a new HVAC system. These factors help ensure your new system remains functional and healthy.

Consider a New Electrical System When Installing a New HVAC Unit or Experiencing Frequent Breakdowns

The primary concern when installing a new HVAC system is whether or not the existing electrical framework can support the new unit. If you’re upgrading in terms of power or size, consider installing new electrical components to help support this system. Conversely, downgrading the HVAC size or strength might allow you to lighten the electrical load on the new system.

Existing systems can also mandate new electrical requirements for HVAC use. If you’re experiencing frequent breakdowns, your system may not be running on the right electrical system. In this situation, installing a new system that can adequately support your HVAC unit may be necessary.

Match HVAC Unit Size With Equal Electrical Power

The power required for your electrical system to support HVAC functioning depends mainly on the size and amount of ducts and vents. Some small units like window inverter AC types or rollaway air conditioners may only need to plug into an outlet. However, multi-duct and split-system units require far greater electricity and a larger breaker to cool or heat your home or office space effectively.

Ensure that you check with HVAC professionals to determine whether your electrical system is adequate for your HVAC unit. Also, check that your breakers are all the correct sizes. Professionals can sometimes rewire certain hookups or components to add power to your system without a complete replacement.

Dedicate a Circuit Breaker to Your HVAC System

Many property owners wonder whether it is necessary to dedicate an entire breaker to their HVAC system. However, because of electrical interactions with other appliances in your home, this is a crucial part of maintaining a healthy system.

Just as dishwashers and lighting systems have a dedicated breaker, you should reserve one for your HVAC system. Assigning a breaker for HVAC functioning helps you manage the electrical charges of other home appliances. Furthermore, HVAC systems without a dedicated breaker are far more likely to break down or require replacement.

Assess Your Electrical System When You Have Frequent Issues

Your HVAC system may experience problems for many reasons. However, suppose your system experiences frequent electrical issues, such as tripping the breaker or shutting down after minutes of use. These breakdowns might indicate your electrical system isn’t adequately supporting HVAC functioning. Professionals can help you identify whether you need to upgrade or rewire your electrical system to continue heating and cooling.

Evaluate Your System’s Ability To Adequately Heat or Cool Your Residential or Commercial Property

Before evaluating electrical system needs, it’s crucial to understand the heating and cooling load necessary for your space. Heating and cooling load is a term in the HVAC industry delineating what size space different units can accommodate. 

HVAC professionals can help you determine the load necessary to cool and heat a space by examining the number of rooms, their size, and the property type. Once professionals evaluate these factors, they can recommend the level of electrical system needed to support your new HVAC unit.

Consider Thermostat Placement During New System Installation

Thermostat placement is one factor of HVAC functioning and electrical system loads that property owners often neglect to consider. Believe it or not, your thermostat’s location will determine many things for HVAC units, including efficiency and electrical use.

Thermostats too close to sunlight or open windows might confuse outdoor temperatures with indoor climates. Since thermostats gauge a room’s temperature to evaluate performance, placing one in a particularly hot or cold area could cause HVAC functioning to double down. This overcompensation decreases efficiency and increases the electrical load on your system.

Eliminate Exposed Wires Before Finalizing the Installation

Exposed wires are hazardous for personnel working to install your HVAC system and can disrupt HVAC functioning. When exposed wires accidentally touch components of your HVAC system, they can overload the electrical charge and cause circuit breaks. Work with HVAC and electrical professionals to address exposed wires and ensure covers follow all code requirements before finalizing your HVAC system.

A malfunctioning HVAC system makes your home uncomfortable and uses an unfortunate amount of power. Diagnosing the problem could include checking the wiring. AC wiring issues can make air conditioner repair more difficult, especially if you don’t have experience working with electrical parts.

Some signs of electrical problems are more evident than others. Knowing what to look for can guide you in repairing electrical issues. You may think you can undertake AC repair as a DIY project, but professional AC repair in Tulsa delivers expert electrical work, resulting in long-lasting repairs and a lower chance of fire or electrical damage.

Below are common AC wiring issues and possible resolutions.

Foul Odors

Electrical wiring problems can produce strong smells, like melting plastic, burning rubber, or a fishy odor. These odors indicate a potentially dangerous electrical problem with your HVAC unit. If you smell burning when your AC kicks on, turn it off and call a professional immediately.

Short Cycling

Loose or faulty wiring may cause your HVAC system to short cycle or turn on and off for increasingly short periods. Before checking your wiring, you can inspect other system components, like your filter, refrigerant, and evaporator coils, as these parts can also cause short cycling.

Increased Electric Bill

Wiring issues can cause your electricity bill to skyrocket. Problems like short cycling cause more energy consumption, so check your HVAC wiring if you notice a jump in your bill.

Thermostat Not Working

If your AC doesn’t respond to thermostat controls like temperature changes, turning on or off, or using only the fan, you may have electrical problems. A professional can help determine whether the HVAC unit or thermostat needs repairs or replacement.

Tripping the Circuit Breaker

Circuit breakers have built-in safety mechanisms to protect you and your home from faulty wiring. If your HVAC system has a problem with the wiring, it could flip your circuit breakers. Repeatedly tripped breakers require an inspection from licensed electricians who know how to safely work on electrical panels and HVAC systems.

How to Fix AC Wiring Issues

If you’re determined to fix your AC wiring issues yourself, check out the most common problems and how you can repair them.

Exposed Wires

The wires inside your HVAC system have an insulated casing made of rubber or plastic. This casing prevents the wires from damage like fraying, corrosion, or separation. If you open up your HVAC system and see split or damaged wire casings, you may need to replace the wires.

In a pinch, you can use electrical tape to wrap the wires and keep them from experiencing further damage. Electrical tape doesn’t constitute a permanent solution, so plan to replace the wires or have an electrician do it for you down the road.

Loose Wires

HVAC units vibrate while running, which can cause wires to loosen from their connections. Loose wires can’t properly channel electricity throughout your unit, making it stop working or work intermittently. You can sometimes tighten these wires yourself, but remember to turn the electricity off before working on them.

Faulty Wiring

DIYers often believe they can wire up their HVAC system using online guides or YouTube videos. While some people have this ability, not all homeowners can safely and correctly connect their HVAC system’s wiring. Faulty wiring causes problems with your unit’s functionality and, in several cases, causes dangerous electrical fires.

If you suspect faulty wiring in your HVAC system, contact a professional electrician to inspect, troubleshoot, and repair the problems.

Repairing AC Wiring

Before repairing AC wiring issues, you’ll need the right tools, such as:

• Adjustable wrench
• Cordless drill or driver
• Insulated screwdrivers
• Needle-nose pliers
• Socket and ratchet set
• Nut driver
• Multimeter
• Voltage tester
• Flashlight

You should also check your HVAC system’s manual for information on your unit’s wiring. Some manuals have wiring guides, while older units may have their manuals online. If you have never worked on electrical wiring before and can’t find information on your unit’s layout, hire a professional HVAC tech, so you don’t cause more damage.

Step One: Turn Off the Electricity

Turn your HVAC unit off, then turn off the breakers at the main electrical panel. This prevents you from accidentally electrocuting yourself or starting an electrical fire.

Step Two: Test Electrical Parts

Check out your unit’s fuses with your multimeter to see if they’ve blown. Blown fuses may indicate a problem with your condensing unit, requiring you to purchase a new part. You’ll want to replace the condensing unit and the fuses before turning your HVAC system on again.

Step Three: Inspect the Access Panel

Open your unit’s access panel and take a look at the wiring. Get up close and use your flashlight to check every wire, turning them and tugging them to eliminate broken wires, split casings, or loose connections. You should also look for signs of pests, like nests or chewed wiring.

Step Four: Replace Problematic Wiring

If you notice any problems with your wiring, replace them. Ensure that you tighten your wires correctly and follow your wiring map to ensure proper placement.

Step Five: Test the Repairs

Close up your access panel and turn on your circuit breaker. Return to your HVAC unit and turn it on as well. Finally, turn your thermostat to its lowest setting and see what happens.

If your HVAC system starts up without any problems, congratulations, you’ve repaired the wiring problems. Should your AC still not work correctly, you may need to replace other parts or consult a professional electrician or HVAC technician.

No one wants their furnace to malfunction during winter. If you fear that you have a failing furnace, you may need to replace the control board. This project may fall under your DIY skills, but if you want professional help, contact the experts on heating and cooling in Tulsa.

Below we discuss the answer to “How do I know if my furnace control board is bad?” and guide you on the steps to replace it.

What Is a Furnace Control Board?

Your furnace control board is the brain behind your furnace. Wires attached to the board run to the motor, gas valve, ignitor, and other necessary components. It controls your furnace by telling it when to kick on the gas and at which point the fan can shut off.

Most home furnaces have an integrated furnace control board that controls your blower and the rest of your furnace. If your control board is bad, you’ll have trouble operating your furnace correctly. Control boards can fail for various reasons, but the tell-tale symptoms look the same:

• Warning lights flashing or staying on
• Inability to settle on a stable temperature
• Stuttering or interrupted furnace sequence

The next steps involve discovering the problem and repairing or replacing your furnace control board. You can do this yourself or contact a professional HVAC technician to ensure they complete the job right the first time.

Five Steps for Checking Your Furnace’s Control Board

Before checking your furnace’s control board, find the items on this list:

• Furnace control board manual (if not available, look it up online)
• Screwdriver
• Electrical tape
• Voltage meter

While most households have the first two items, you might wonder why you need a voltage meter. This tool helps you troubleshoot your control board, other parts of your furnace, and many other electrical parts of your home.

After gathering the necessary tools, check your control board with step one.

Step One: Remove Access Panels

Using your screwdriver, take your furnace’s access panels off. You can usually find the control board near the blower at the bottom of the access.

Step Two: Visual and Odor Inspection

Some control boards show apparent signs of damage. For example, you may see burn marks or bad wires, indicating that you’ve lost the entire board.

If you don’t see any damage, use your nose. Strange smells or burning odors easily answer the question, “How do I know if my furnace control board is bad?”

Step Three: Check Diagnostic Lights

Your control board has a diagnostic light that can tell you if issues have occurred. Count the blinks and refer to your manual to deduce the problem. If the indicator light isn’t on, your control board has no power.

Step Four: Test for Power

First, check if your furnace has a door switch to test the power coming into your control board. Tape this switch down to ensure no electrical accidents occur.

Locate the common wire leading from your transformer into your control board. The wire should have a black exterior with a 120VAC Hot label. Use your voltage meter to determine if the line has power.

If your board’s wire receives a reading of 120 volts AC, then the power works fine. Power going into your board should light up the indicator light, but if it remains off, it’s time to consider furnace repair and possibly replace the board.

Step Five: Test the Terminals

If the power does make it to your control board and the indicator light blinks, you need to test the thermostat terminals. Turn your furnace off and use a wire to connect and test the terminals, turning the furnace on and then back off between each test. The terminals to test and positive responses include:

• R and G: Blower should come on
• R and W: Heating should come on
• R and Y: Cooling should come on

These tests may jump-start your furnace, proving that the control board doesn’t need replacing.

What Should I Do If My Furnace Control Board Is Bad?

If all of your testing doesn’t get your furnace working again, you may need to replace the control board. You can replace your own board, but you’ll need a thorough working knowledge of your furnace to avoid creating more significant problems.

A professional can help you purchase the correct control board for your furnace and install it for you. However, if you insist on installing your own furnace control board, use these steps to guide your way.

Step One: Take a Photo

Photographing your current furnace control board can guide you in wiring your new one the same way. You can also use your control board’s manual if you have it handy.

Step Two: Turn Off the Furnace

Forgetting to turn your furnace off may short out other parts of your house and cause significant injuries from electrocution.

Step Three: Remove the Old Board

Take off the access panels on your furnace so you can fully reach the control board. Disconnect all wires and connectors. Use your screwdriver to remove any screws holding the board in place.

Step Four: Install and Test

Place the new board inside your furnace and refer to your photo or manual to guide you in reconnecting everything. Once finished, place your access panels back onto the furnace and turn your power back on. Use your thermostat to ensure the furnace responds to temperature commands.

Whether you’re shopping for your first HVAC system or replacing one, knowing the differences between systems can help you make the best choice for your needs. HVAC systems come in forced-air and central air variations. In this blog, we’ll discuss forced air vs. central air and highlight the benefits of each to help you decide which is the right fit for your home.

When it comes to HVAC, there are a lot of technical terms the average person may find confusing. Quality Heating, Cooling, & Plumbing, the most knowledgeable and experienced HVAC contractor in Tulsa, OK, want you to have all the information you need when buying a new HVAC system. By hiring us, you can rest easy knowing you made the right choice.

What Is Forced Air, and How Does a Forced-air System Work?

Often, you’ll see industry professionals using the term “forced air” when referring to air heating systems. While this may be a proper use of the term, it’s not quite that simple. Realistically, any HVAC system that sends temperature-regulated air through vents and air ducts into a home is a forced-air system.

HVAC technicians who use this term exclusively for heating are probably thinking about a furnace or heat pump.

How Does a Furnace Work?

Gas, oil, and electric furnaces work pretty much the same way. Furnaces heat houses through the following process:

• Propane, oil, natural gas, or electricity generates heat for the furnace.
• This heat passes through a heat exchanger.
• As the air in the house’s ductwork flows over the heat exchanger, it becomes warm.
• Finally, the blower in the furnace forces air through the ductwork to heat the house.

Most people refer to furnaces as forced-air furnaces because they send heated air throughout the rooms in a house with a blower.

How Does a Heat Pump Work?

The heat pump operates like an air conditioner but differs in that it heats and cools. In warm seasons, it pulls heat out of the house and releases it outside. During the colder months, it takes heat from the outdoor air and sends it into the house.

Heat pumps produce warmth in a house through the following steps:

• The evaporator pulls heat from outside the house and delivers it to a heat exchanger. Different heat pumps will pull heat from the ground, the air, or a nearby water source.
• When heat meets the refrigerant, it causes it to evaporate. The evaporated refrigerant heads to the compressor, where the fluid compression amplifies the heat.
• Once the refrigerant fluid becomes a gas, it travels to the condenser to return to a liquid form. The condenser is a secondary heat exchanger that allows water from the central heating system to absorb the heat.
• The system then distributes the heat throughout the house.

Some heat pumps use heated water to warm a house by sending it through pipes under the floors or into radiators. Other heat pumps use motorized blowers to send hot air into the ductwork.

What Is Central Air Conditioning, and How Does It Work?

A central air system uses a closed circuit of refrigerated air to keep a house cool and comfortable. Most central AC systems consist of outdoor and indoor units working in tandem. Central air cools a home through the following process:

• A vent pulls warm air from inside the home, where it flows over the evaporator coils. The evaporator coils absorb the heat and send cold air back through the ductwork.
• Once the refrigerant absorbs the heat, it changes from a liquid form to a gaseous state and heads to the compressor. The compressor decreases the volume of the gas, increasing its temperature and pressure.
• The gas heads to the condenser in the outdoor unit, where it releases heat outside. This temperature change converts the gas back into a liquid.
• Once the refrigerant cools, it is sent back through the system to repeat the process.

Forced Air vs. Central Air: What Is the Difference?

The main difference between central air and forced-air systems is that a central air system refers specifically to the cooling system. A central air conditioning system uses vents, ducts, and a plenum (a box responsible for moving air) in a forced-air setup to deliver temperature-regulated air. A central air conditioning system uses the same duct system your furnace does to distribute cool air throughout your home without no other connection.

The use of the same ductwork and similar temperature conditioning processes make these two forms of air control hard to distinguish, which is why many industry professionals use the terms interchangeably.

Should I Choose a Forced-air or Central Air HVAC System?

A forced-air system gives you the benefit of filtered air and the ability to upgrade the filtration quality of your system. A forced-air system can adequately cool a house with great energy efficiency while improving air quality and naturally reducing humidity. Forced-air systems don’t require excessive maintenance and can lower your monthly energy bills.

There are many high-performance, energy-efficient air conditioning units on the market today. If your home seems to be constantly humid, a forced-air HVAC system may be right for you. Conversely, if your home has a working air duct system, staying with a central air system may be your best option. Be sure to find a reliable HVAC technician to install your new system to ensure optimal performance and reduce utility bills.
