How To Fix a Freon Leak in a Window AC Unit in Haskell, OK
Window-mounted HVAC systems come in mighty handy. If you live in a small building or recently added a room without HVAC connections, you can purchase and install this equipment for a fairly inexpensive price. However, window units still have their fair share of HVAC issues, such as refrigerant leaks.
As your trusted source for AC repair services in Haskell, OK, Quality Heating, Cooling, Plumbing & Electric knows how to fix a refrigerant leak in window AC units. We’ll share our knowledge about this topic below so you can make quick decisions about when to call us.
What Causes Refrigerant Leaks in Window Units?
Most refrigerant leaks develop because of old, corroded parts. For instance, the refrigerant lines in window units consist of mechanical components made predominantly of metal. Metal becomes rusty as time passes, which allows the refrigerant to escape.
Sometimes, your window unit springs a leak because of incorrect installation or damage caused by sudden, blunt force. An HVAC technician or a heating expert in Haskell, Oklahoma, who knows how to fix a refrigerant leak can recharge your AC unit with a top-off and repair the damage. However, you’ll typically face leaky refrigerant because your system is outdated and still uses Freon, which is no longer manufactured.
Recognizing The Signs of Leaky Refrigerant in Haskell Window Air Conditions
How do you know you need window AC repair services in Haskell, Oklahoma? Let’s explore the specific symptoms that occur in this contained air conditioning equipment below. You’ll find out what to look for and how to safely handle it.
Pronounced Hissing Sounds
One of the first low-Freon symptoms you might notice is a persistent hissing noise from your unit. It might also sound like a soft bubbling as your equipment tries and fails to cool the air it takes. The noise means the refrigerant is escaping from the window unit, turning from a liquid to a gas as it exits.
Dripping Water Near the Unit
You need an HVAC technician service that knows how to fix a refrigerant leak in window AC units if you discover puddles of water on the window sill or beneath the window. Refrigerant leaks can cause the coils to freeze. Once they thaw, that excess moisture becomes a liquid that escapes from the unit’s interior. Keep an eye out for soggy carpet, noticeable dribble, and water stains on hard floors.
Excess Indoor Moisture
Refrigerant helps remove humidity from your interior spaces. When it leaks, your window unit has nothing to absorb and transfer the moisture out of the room. As you try to relax or nap, you’ll notice the air feels lukewarm and sticky with vaporized water rather than cool, dry, and brisk.
The warm, humid environment creates an atmosphere conducive to mold growth. Lack of sunlight and proper airflow will enable the spores to spread. This particular symptom can make your room unhealthy and filled with allergy triggers.
Pungent Odors
Refrigerant has an unmistakable smell — somewhat sweet with a sharp, chemical twang — that you’ll quickly detect. Some people think the odor smells almost floral, while others pick up on a smell that resembles car exhaust. When you detect an off-putting scent coming directly from your window unit, consider reaching out to a technician who knows how to fix a refrigerant leak.
How To Fix a Refrigerant Leak in Window AC Units
What might a technician do to fix your leaky refrigerant line? They’ll likely begin with a refrigerant leak detection service to ensure that your problems come from a leak and pinpoint where it developed. Then, they’ll finish the service by sealing refrigerant lines with small patches.
Bigger, more problematic leaks often require more intensive remedies, like replacing the affected parts altogether. However, you should think about replacing the whole system if:
- You installed the unit over ten years ago. Most window units don’t last more than 15 years.
- You’ve dealt with a long string of previous repairs. Increasing repair demands typically mean the system is too outdated to revive.
- Your unit still uses Freon. Systems that run on Freon have been phased out.
- It doesn’t supply the same comfort level as it once did. You’re shelling out money for repair services in exchange for low comfort quality.
