5 Signs You Need Air Conditioning Repair

Posted on: May 31, 2022

Outdoor air conditioner unitIf you’ve noticed anything unusual or different about how your cooling system runs, you might need professional air conditioning repair — even if the problem isn’t yet affecting your comfort.

Little abnormalities can develop into bigger issues, so taking care of them early could save you a lot of money, frustration, and discomfort.

Read below to learn the five common signs of air conditioner malfunctions that are likely to be overlooked, downplayed, or wholly unnoticed and what might be causing those issues.

System Short-Cycling

If your air conditioner turns on and off regularly, especially if it does so without reaching the temperature you have your thermostat set to, then you need AC repair. Under the best circumstances, your air conditioner should run until you hit your target temperature. It may run continuously if it’s at its absolute limit on the hottest day of the year.

If you’ve recently installed a new air conditioner, it may be short-cycling because it is improperly sized for your home. If your cooling system suddenly starts short-cycling, it could be due to low refrigerant from refrigerant leaks, a miscalibrated thermostat, or electrical issues.

Frequently Tripping Circuit Breaker

It’s easy to treat breakers flipping as a nuisance that doesn’t warrant further investigation after resetting the breaker. Whether it’s affecting your air conditioner or any other electrical device or circuit in your home, it’s a clear sign of trouble if your breaker frequently trips.

Nearly any problem with your AC can lead to breakers tripping:

  • Dirty air filters can reduce airflow and cause your unit to overheat, tripping the breaker for electrical safety.
  • Dirty condenser coils can’t effectively disperse heat, which can lead to an electrical short.
  • Missing or broken components cause the unit to use more electricity, and the circuit may not be able to supply enough power, tripping the breaker.

Frozen Air Conditioner Coils

You may be able to resolve frozen AC coils yourself, so many homeowners change their air filter and forget about it until the next time their evaporator coils freeze.

Frozen coils occur when moisture accumulates on your evaporator coils. This is most often due to a dirty air filter and poor airflow, but it can also happen because of leaking or low refrigerant.

Rising Energy Bills

If your power bills keep rising without a significant change in your energy usage, your AC is a likely culprit. Reduced energy efficiency can be caused by system age, especially if you don’t keep up with annual AC maintenance.

However, it can also signify a developing issue warranting repair, especially for a newer unit. Missing or damaged components inhibit performance and make your system work harder for the same or diminished comfort.

Before calling an HVAC professional, replace your air filter if you haven’t done so in the last three months.

Strange Sounds Coming From the Unit

Your air conditioner will make some noise at the beginning and end of each cycle. However, an HVAC professional should always investigate weird AC noises such as banging, squealing, hissing, and screeching.

These noises are usually a result of mechanical failures or loose components, such as:

  • Fan blades
  • Fan motor bearings
  • The fan belt
  • The compressor

Electrical problems can also cause buzzing noises.
