Does My Wall AC Need Repairs?

4 months ago

All appliances need maintenance from time to time, no matter how well you take care of them. Responding to repairs quickly is crucial to preventing damage and controlling costs, so we’ve put together a helpful list of ways you can tell your wall AC might need repairs.

Your Wall AC Is Blowing Warm Air

There are a few different reasons your air conditioner might be blowing warm air instead of cool. One of the most common is leaking or low refrigerant, since this fluid is what pulls the heat out of your space. Another issue might be your thermostat settings.

If the temperature set is higher than the ambient temperature of the room you’re in or if you accidentally switched your thermostat to heat, the air from your vents might feel lukewarm or even hot.

The Airflow Coming From Your Vents Is Weak

If the air coming out of your vents is the right temperature but the flow seems weak, this may be due to a different set of problems. For example, your air filters might be dirty or clogged, especially if you have pets that shed.

Or, your blower motor might be going out. You can check and clean the filters on your air conditioner yourself, but aside from that, airflow that feels faint should be addressed by an HVAC professional.

Of course, if your AC is blowing warm air and it feels weak coming out of the vents, you could have multiple issues that need to be repaired.

Your AC Makes Loud Sounds When It Runs

Wall ACs are intended to be incredibly quiet. In fact, this is one of the best features of owning a ductless air conditioner. But if your unit isn’t working properly, you may start to notice that it runs louder than usual. You may even hear a humming, buzzing, or knocking that gets worse as time goes on.

Often, clanking or banging sounds can be attributed to loose parts or snapped belts, particularly when combined with warm or weak airflow. Other things to check when your AC is making strange sounds are the fan motor, the condenser fan, the compressor, the relay switch, and the expansion valve.

There’s a Musty Smell Coming From Your AC

If you start to smell mildew or a musty, basement-like smell coming from your air conditioner, this is probably exactly what it seems like. Condensation buildup can result in mold and mildew growth, which at best can make your space unpleasant and at worst potentially trigger allergies and respiratory health issues.

Chances are, you don’t need an expensive repair. Replacing your filters and deep cleaning the inside of the unit will likely do the trick. This should be done on a regular basis anyway, like you might get the oil and filters changed in your car.

Your Space Is More Humid Than Usual

Ductless mini-splits are excellent at controlling humidity in a space, even with the gorgeous coastal weather in Cape Cod. If you notice that your home or workplace is starting to feel hot, sticky, or muggy, check the humidity levels.

High humidity likely means that your air conditioner isn’t doing its job. Don’t be too quick to buy a dehumidifier at the store – this may give you a false sense of security by removing humidity without addressing potential AC issues.

Your Energy Bills Are Increasing

Cape Cod summers can get hot and it’s pretty normal for your electric bill to go up as you run your air conditioner. But if your expenses continue getting higher and higher, this is a good indicator that there’s something wrong with your unit.

If your filters are clogged, this could prevent cool air from getting to your space, causing you to adjust the thermostat and use more of your AC’s power to stay comfortable. An older unit or one with loose parts may also be using more energy than it needs.
