4 Reasons Your Air Conditioner May Overheat

It’s been a hot summer here in the Northeast, and at our West Chester cooling company, we’ve seen our fair share of home air conditioning problems. If your air conditioner has overheated or you’re afraid it may, here are some of the most common reasons for it:

Dirty Coils

Each air conditioning unit is fitted with condenser coils that carry refrigerant through them: in the indoor unit, the coils absorb your home’s heat and the hot refrigerant travels to the outdoor unit. In the outdoor unit, the coils release the refrigerant’s heat. However, if your outdoor unit’s coils are dirty, the dirt acts as an insulator and the coils can’t release the heat that they need to. Because the heat is trapped, it can cause your unit to overheat.

Clogged Filter

Your HVAC filter is there to do just that – filter out contaminants so that they don’t flow through your air conditioning unit and into your home. However, HVAC filters can collect a significant amount of dust, dirt, dander, pollen, and other airborne particles in a short amount of time – especially during the spring and fall seasons. A dirty filter means a lack of clean air, which can lead to overheating. At our West Chester cooling company, we recommend replacing your HVAC filter every two to three months (and even more frequently if you have pets).

Too Much Use

Even though your air conditioner is there to keep you and your family cool, using it too often can cause it to be overworked and therefore overheat. Try limiting your use in order to extend your air conditioner’s lifespan. Instead, use ceiling fans or floor fans to keep cool and do your heat-producing housework (like laundry or using the oven) in the early morning or at night.

Low Refrigerant

If your air conditioner is low on refrigerant, it will cause your unit to run more than it needs to and in turn, can cause overheating. A few signs of low refrigerant include weakened cooling performance, slower cooling performance, and ice build-up on your outdoor unit. However, with regular maintenance check-ups by our cooling experts, you can make sure your refrigerant level stays where it should at all times.
