The air conditioner has many parts, one of which is the compressor. The compressor is essential to the cooling system. When the compressor begins to fail it is important to tend to the repairs to prevent additional problems. To prevent compounding problems it is important to diagnose a failing compressor. Air Supply Heating & Air Conditioning will share how to troubleshoot a failing compressor and when to seek professional help.
AC Compressor Troubleshooting Guide
When an air conditioner’s compressor begins to develop problems, often one of the first signs is warm air coming from the air duct vents. When you can feel warm air blowing through the vents, yet the air conditioner seems to be running fine, this can be due a few different issues. One of the common reasons why warm air is blowing through the vent is due to a failing compressor. When you believe the compressor is the issue, you will want to take the right steps when checking the compressor. The first step is to first turn off power to the air conditioning system. To ensure safety you always want to turn off the power as your unit can switch on or exposed wiring can cause electrocution. Once the power has been turned off you can then inspect the compressor. The compressor is located inside the outdoor unit. If the unit is on the roof, we strongly recommended that you seek out a professional HVAC technician to troubleshoot your air conditioning problems. If the compressor is located inside the outdoor unit, you will need to remove the exterior panel for a closer inspection. Start by checking the compressor temperatures. Once the power to the air has been turned off, immediately touch the surface of the compressor. If the compressor feels extremely hot to the touch, then the air conditioner system may actually be low on refrigerant. Next, check the wiring that is connected to the compressor. Look for any damage, such as burnt cords or lose or worn wiring. Look closely at the compressor terminal box and the wiring that feeds out as this is a common site for wiring issues. If the compressor feels fine and the wiring appears intact, then inspect the fan motor. The fan motor can have a major effect on the compressor. If the fan motor is not turning the fan or running properly, the compressor can overheat and cause premature wear on the compressor.
Response to AC Compressor Failure
When you detect a problem with the air conditioner’s compressor, you will want to turn the air conditioner system off and seek out a professional HVAC service. If you continue to run the air conditioner unit with a bad compressor it will cause compounding problems. The compressor is a key component for the creation of the cooler air that flows into the home. When a single component is flawed then the entire air conditioning system becomes stressed. Stress on the air conditioning system can lead to premature failures and replacement of the air conditioner.
