10 Reasons of AC Compressor Overheating & Solution

Air conditioner compressor is a significant part of any AC unit, which is placed outdoor and does the pumping of refrigerant through the system. Sometimes, the compressor might completely stop working due to overheating, which is one of the most common problems plaguing an AC. However, in Parker Co the causes behind such overheating may differ.

Causes of AC Compressor Overheating


Most often, overheated compressors are a result of imbalanced voltage, slugging of refrigerant, high temperature of return gas, lack of cooling on the outside, migration issues, and a few other causes including the following:

  1. Dirt in the Filter: It is the filter of the AC unit that prevents it from absorbing unwanted pollution circulated by outdoor air. But in the process, the filter accumulates plenty of dirt and debris, which in turn creates pressure on the compressor to work more and cause it to heat up.
  2. Unclean Condenser Coils: This refers to the tube that extends outdoor from the air conditioner unit. Even if your unit has a York AC compressor, the coils are bound to have deposits of dirt and pollutants in them due to exposure to the outdoor conditions. These deposits act as insulators that prevent the refrigerants from absorbing indoor heat and letting it out, thereby creating the compressor to work more and blow out after a while.
  3. Old Compressor: If you have been using the same AC for over 15 years, there is a high possibility of the parts wearing out and the compressor not being able to do its job properly and get overheated while trying to work for long.
  4. Low Refrigerant: At times, low refrigerant charge may cause extensive working of the unit, resulting in overheating of compressor.
  5. Lack of Maintenance: This is a common cause of compressor overheating. Lack of maintenance indicates unclean filters, condensed inner layers, pipe breakage, damaged filters and more. All these considerably slow down the process of letting out indoor heat and put more pressure on the compressor, thus overheating it.
  6. Oversized Room: There are possibilities that you have placed an air conditioner designed for smaller rooms into a bigger one. This makes the air conditioner work harder than required, thereby heating up the compressor.
  7. High Voltage: High voltage surge would damage the capacitor inside the unit, which makes the compressor motor to overheat and trip.
  8. Short Circuit: Though this is a rare occurrence, it might even result in the burning of the AC units due to compressor overheating.
  9. Internal Parts: There are possibilities that the internal mechanical parts of the compressor wear out due to age or overuse. This is indicated by noise and shutting down of the unit.
  10. Lack of Insulation: When your unit is very old or exposed to extreme sunlight, it tends to lose the insulation and create pressure on the compressor to heat it up in Parker Co atmosphere.

AC Compressor Overheating Solution


Having understood the various causes for overheating of AC compressor, it is high time to seek solutions. While the causes for compressor heating are compartmentalized, the solutions converge to one –maintenance of your AC unit regularly. This involves changing the filters, cleaning them, checking the block in the outside pipelines, opting for timely AC compressor repair and more.

When you are able to identify one of the best AC maintenance and repair companies in Parker and opt for an annual maintenance plan, you can relax since the responsibility will be shifted to these pros. These experts not only clean all required parts and replace the filters but also identify the parts that are wearing out and act in advance rather than waiting for the unit to shut down. Even your AC compressor replacement cost would be minimal when you have a proper maintenance plan in place. After all, it’s better to be proactive and take precautionary measures rather than being reactive and suffer every now and then.

  1. If they any possibility on discharge capillary tubing blockage, due to aging and corbon deposit, it cut in and out in 2-3 min due to compressor overheat, and no adnormal sound during running. Pls advise thks
