How Do You Diagnose An Air Conditioner Problem?

Air conditioners have become an essential part of every homeowner’s life, especially those who live in areas with high summer temperatures.

Unfortunately, many homeowners have issues with their air conditioning units periodically. If your air conditioner system begins to malfunction, there are numerous steps you can take to diagnose and fix the problem.

Common Air Conditioner Problems

When diagnosing AC problems, the best part is that there are a few obvious culprits. Here’s everything you need to know about common AC issues.

  • A circuit breaker tripped.
    If your air conditioner won’t turn on, the first thing to check is for a tripped circuit breaker. If the circuit was overloaded, there’s a good likelihood the culprit is a tripped breaker.
    That is especially prevalent in the summer when temperatures increase, and your air conditioner unit works overtime to keep you comfortable. It is possible, though, that a power outage caused your air conditioning system to trip a breaker. 
    All you have to do is locate the air conditioner circuit breaker and completely turn it off. Then wait a few moments before switching it on.
  • Thermostat problems
    The thermostat is an essential component of your AC system. So, if your thermostat isn’t working correctly, your air conditioner won’t turn on.
    If your thermostat still fails to work, you need to replace it. A professional expert will need to come in and check on it because there might be an electrical fault with your thermostat.
  • Refrigerant leaks
    There are several methods to diagnose a refrigerant leak before your air conditioner stops working. If your air conditioner isn’t cooling your home, your utility costs are increasing for no apparent reason, or you hear a hissing sound, you most likely have a refrigerant leak.
    It may appear simple to diagnose and repair your refrigerant problem, but this is another job for a reliable AC tune-up in Galliano, LA specialist. They can readily evaluate your refrigerant levels and make any required modifications.
  • Inspect compressor
    When the compressor fails to function effectively, the air conditioner does not perform to its full potential and sometimes does not work. The cause could be a burned wire, a faulty start capacitor, or a faulty compressor itself.
    To repair a malfunctioning compressor in your AC, clean the condenser coil, inspect the capacitor, clean the outdoor unit’s fan, and replace the compressor.
  • Frozen coils
    When your AC coils freeze, you may notice problems with airflow, low refrigerant levels, or the fan’s operation. This is another air conditioner issue left to the AC repair professionals in Lockport, LA. 
    Even if you could confirm that the coils are frozen, you may still require the services of a professional to diagnose and repair the underlying source of the problem.
