Causes of a Compressor Burnout and the Cost to Replace

CompressorTypically, an AC system comprises four main components which include an evaporator, expansion valve, condenser, and a compressor. The compressor is a crucial part of the entire cooling process because it takes in Freon and compresses the gas under high pressure and temperature. The compressor then emits hot gas and circulates the remaining cool air throughout the system. A dysfunctional compressor causes your AC to underperform.

How a Compressor Works

The main work of the compressor is to direct the hot gas towards the condenser coil located within the outdoor unit. The condenser coil is fitted with fans that blow air on it and transfer any heat left over to the outside air. The effect of this is that cool air circulates throughout the system and your home. This is a much complex process than it is explained here.

Causes of Compressor Burnout

If your unit no longer blows out cool air or you are experiencing some issues with your HVAC system, chances are high that your compressor is faulty. One of the key signs of a failing compressor is the fact that you may no longer hear the fan from the unit whenever your AC turns on. You may also hear some loud noises coming from your unit.

Among the notable causes of a compressor burnout include:

  • Poor HVAC maintenance which leads to damaging buildup on your compressor.
  • Power surges may also cause electrical failures which lead to compressor burnout.
  • Excess moisture may cause chemical reactions that form acid byproducts which eat away the compressor.

The Replacement Cost of a Compressor

Depending on where you buy your compressor, you are likely to pay varying amounts. The person doing the installation may also charge you dearly unless you know the average costs to install such units.

Assuming you are doing the installation yourself, expect to pay anywhere between $300 and $600 for a compressor that fits your AC well. If you are like a majority of the people who want nothing to do with the installation of compressors, you may have to get a HVAC technician. In this case, you may pay anything between $1,500 and $2,000.

The best approach to maintaining the functionality of your compressor is to schedule regular cleanings with your local HVAC expert. Doing this prevents unannounced failures as well as costly repairs and the inconvenience caused.
