5 Signs Your Air Conditioner Compressor is Failing

The compressor is one of the key components of your air conditioning system as it produces cool air by pumping refrigerant throughout the system. If your compressor is failing, it needs to be addressed right away before your air conditioner stops working. Here are five warning signs that indicate a potential compressor problem:

  • Your air conditioner does not cool. When the compressor is starting to fail, it cannot properly pump refrigerant through the system. Warm air coming from your vents is a surefire sign of a compressor problem.
  • Your circuit breaker repeatedly trips. Frequently tripping the circuit breaker is another sign of a failing compressor. The compressor might be working too hard and overheating, tripping the circuit breaker and cutting off the power to the unit. You should have your unit repaired if this continues to happen.
  • Your air conditioning unit makes a lot of noise. It’s normal for your outdoor unit to make some noise. However, if it’s making much more noise than usual, it’s a sign of trouble. If you hear a chattering, clicking, or rattling sound, the compressor is likely to be the cause. The noise can indicate a loose belt in the compressor or an issue with the fuse.
  • Your outdoor unit vibrates or shakes when starting. Does your condenser unit shake while it’s turning on? This is a “hard start,” which means that it is struggling to turn on. One of the most common causes of hard starts is a failing compressor.
  • You see puddles or moisture around your air conditioning unit. Puddles around your air conditioning unit indicate that there is refrigerant leaking from the compressor. If the leak isn’t fixed, your air conditioner will no longer be able to generate cold air.

Air Conditioning Contractor Explains Why Your AC Keeps Tripping the Circuit Breaker

A circuit breaker protects your electrical system and the electric devices in your home from excessive electrical current. Too much electrical current can damage your air conditioning system and heat up wiring to the point of causing a fire. This is why you should never continually reset a circuit breaker every time it trips.

Now and then a one-time power surge may trip the circuit breaker, such as from a lightning storm. To rule this out, reset your circuit breaker only once before turning your air conditioner on. If the breaker trips again, there’s a problem with either your circuit breaker or the AC system. If the breaker has a burning smell, feels hot, or you see signs of charring, the circuit breaker has gone bad. Otherwise, the issue probably lies with your air conditioner.

Here are four possible problems with your AC:

  • The air filter is dirty. A dirty air filter increases resistance to air flowing through it which then intensifies the workload on your AC system, which ultimately increases the draw of electrical current. This increased current trips the circuit breaker. Replace the air filter and try again.
  • The condenser unit requires cleaning. The condenser unit can get full of dirt and debris, especially in its fins. This reduces air flow through the fins and prevents the condenser from efficiently dispersing heat. The AC then draws too much current, which trips the circuit breaker. If the condenser is dirty and you have experience cleaning the condenser unit, then give it a good cleaning.
  • A motor has a problem. A motor could have shorted out from running too hot. For example, if a fan motor is working too hard to push air, the internal wiring could overheat and break down the insulation; thus causing a short, which trips the breaker. The motor having a bad capacitor can also trip the circuit breaker.
  • The air conditioner has a refrigerant leak. Too little refrigerant causes the AC system to work too hard. If this is the problem, there is no point in refilling your AC with more refrigerant. The fact that your AC worked without problems in the past means that it used to have plenty of refrigerant; which means that your AC has a leak and should be fixed.

3 Signs You Should Get Air Conditioning Service

If your home has poor indoor air quality, it could be a sign that your HVAC system needs to be serviced. Dander from your pets, mold, dust, and household chemicals can really harm the air quality in your home. Since this can cause serious health problems if left unresolved, it’s important to do everything you can to make sure your family is healthy. If you experience any of the three you may want to call Cunningham Associates Heating and Air Conditioning in Atlanta, GA to receive air conditioning service.

Warm and Drafty Spots

Sometimes bugs or contaminants can block your air conditioner and make certain areas of the home warm and drafty. This could be a sign that your unit is leaking or clogged. We recommend getting your air conditioner cleaned and inspected periodically to prevent this from happening.

Odor and Foul Smells

Are you starting to notice a foul odor in your home? You can also ask friends and family if they smell anything unusual just for confirmation. Pollutants such as mold and pests can make your home smell if they get stuck in your air conditioning ductwork. A professional HVAC company can inspect your air conditioning unit and find animal nests, bugs, molds and other pollutants that are making your home smell bad.

Allergies

Have you noticed that you or other family members are sneezing more? Bad air quality can cause headaches, coughing, sneezing and other allergy symptoms. If you believe your allergies only get worse when you spend time at home, it may be a sign that you should have your HVAC system checked and get an air purifier.
