The compressor is an essential component that transforms the refrigerant from a liquid into a gas and back into a liquid state. When the refrigerant is turned into a gas, it removes the heat from the air which is how we get the needed cool air that is then circulated throughout the home. When the compressor fails, the cooling system fails, leaving the home very warm and uncomfortable. West Lake Houston HVAC will share some of the most common signs of compressor failure and when to seek professional repairs.
Air Conditioner Running But Not Cooling
When a compressor begins to fail you may notice the air conditioner is running but the indoor temperature isn’t cooling down. When you cannot detect a problem with the air conditioner and the entire system appears to be running, this is a sign the compressor is at fault. When the compressor isn’t functioning it will not remove the heat from the air, yet the air conditioner will continue to run and finish the cycle. You may even feel warm air coming from the air vents and into the home. A compressor will fail for a few reasons such as:
• Faulty Wiring
• Failed Contactors
• Failed Capacitors
• Dead Motor
Depending on the reason why the compressor has failed the repairs may vary. The wiring or the contactors or capacitors may need to be repaired or replaced. However, a failed compressor motor will require replacement which isn’t the cheapest component to replace.
Ice on Evaporator Coils
The compressor works in conjunction with the evaporator coils to help absorb the heat from the air. As the air flows over the evaporator coils, the heat is absorbed. At the same time, condensation will form. When there is an air flow restriction the condensation will ice up as the air conditioner will run for long periods of time. When ice forms the air cannot flow to the compressor, which in turn causes the compressor to overheat. When a compressor overheats this can cause major problems and even lead to burning out the compressor’s motor. Ice on the evaporator coils are often caused by:
• Dirty Evaporator Coils
• Dirty Condenser Coils
• Dirty Air Filter
It is very important to keep the air filter and the coils of the air conditioning system clean. With proper HVAC maintenance and tune-ups the coils should always be kept cleaned. Make sure to change out your air filter every one to three months and you should avoid ice building up on your air conditioner.
Noisy Air Conditioner
Often when the compressor develops a problem there may be an accompanying strange noise. The noise coming from the compressor may help determine the problem. For example:
• Humming indicates an electrical connection problem or failing motor.
• Rattling indicates a loose part or separated part.
• Squealing indicates a dying or overheating compressor.
