3 Common Reasons a Home A/C Will Overheat and Shut Down

Imagine you get home from a long-day work only to find your air conditioning unit not working. It’s a real DISASTER, right?

Unfortunately, this is a usual case in many residential properties in Denton, TX when the summer season steps in. And the most common diagnosis- an overheating air conditioning unit! Why does your A/C overheat in the first place? Check out these common reasons and what you can do save your comfort from this chaos:

  • Dirty Air Filters

Do you still remember the last time you replaced or at least cleaned your air filter? If it has been a long time now, there’s already a big population of dust and dirt particles lurking in the device which hinder the proper flow of air. This is when your air filters turn from a friend to a foe.

When the airflow is obstructed due to the buildup of particles in the filters, your unit will work harder than its normal operation. This results are either the system overheats and trips the circuit breaker or you’ll experience a total A/C breakdown.

We know you don’t want to experience any of these, that’s why we recommend you give your filters enough attention. Replace or clean them every 1-3 months to keep your unit’s proper performance.

  • Dirty Condenser Coils

The condenser coils are tubes on your air conditioning unit responsible for removing heat from the refrigerant. When the coils are covered with dust, dirt and other particles, it becomes insulated therefore preventing the refrigerant from releasing heat easily.

Imagine yourself wearing a sweater on a hot summer day. Your body wants to release heat, but the jacket is preventing the heat from leaving.

Since the refrigerant can no longer absorb more heat from the air, there’s a tendency that your unit will produce lukewarm air or worse, it will keep on running to reach the temperature set on your thermostat. This is where overheating takes place.

  • Low Refrigerant

You know if your air conditioner is low on refrigerant when you see ice build-up on the outside unit, or your A/C is not cooling as fast as it should. If this is your case, you should seek immediate help for you are dealing with refrigerant leaks.

Only professional experts have the skills and expertise in identifying the leaks and providing rightful solutions to bring back the performance of your unit.
