Causes of Compressor Failure

Air compressors are robust pieces of equipment that are crucial in manufacturing and other commercial situations. These powerful tools make easier tasks that would otherwise take a lot of time and effort.

If you take care of your compressor, it will provide constant and reliable cooling for your space. This necessitates that you schedule maintenance for your air conditioner twice a year with a reliable AC service firm. If you need maintenance, look for They’re familiar with the issues that can lead to AC compressor failure and can take steps to prevent it.

When anything breaks, it can take a long time to figure out what’s wrong and fix it. Fortunately, air compressor issues are usually easy to fix. Better yet, breakdowns can be avoided entirely with consistent upkeep. The most typical reasons for air compressor failure and how to fix them are discussed below.

  • Electrical Issues:

In the event of an electrical failure, acids can build up and do significant damage to the compressor and other components. Make sure the technician checks for these acids if you have a broken compressor. Even if he does find them, the entire system has probably been irreparably damaged by the electrical burnout, so it would be a waste of time and money to try.

But if you have an experienced technician like check out your system, he can discover and fix faulty wiring, fuses, and contractors before they bring down the entire system and trigger AC compressor failure.


  • Pressure and Flow Problems:

Problems with pressure and flow rate are typical for air compressors. If your hose isn’t blowing air, for instance, this could indicate:

  • There is an incorrect pressure setting on the regulator.
  • Your tank is completely empty.
  • The discharge coupler has the incorrect hose connector attached.

It may be necessary to replace a corroded or otherwise damaged intake filter. Overheating of the motor and longer times required for the compressor tank to build the correct air pressure are typical indicators that it is time to do this. 

  • Oil Issues:

Oil is used in compressors to prevent overheating and keep moving parts lubricated, but this oil must never enter the air distribution system. If that happens, seals might expand, break, and fail.

This issue can be avoided by routinely replacing the intake filter and the piston rings. You can also avoid oil problems by never overfilling your oil tank and always using the correct oil viscosity.

  • Dirty Compressor Coils:

The condenser coils are a particularly weak point in any cooling or refrigeration setup. Build-ups of dirt and mineral scale have the potential to adversely affect the functioning of all other major parts. Thankfully, these can be regularly cleaned to preserve functionality.

  • Clogged Drainage Systems:

Any cooling system will lose efficiency if the refrigerant lines become blocked. Over time, the pressure and temperature will rise, and while this may be a gradual process, it can also happen quite quickly. Overheating leads to compressor failure in the long run.

Troubleshooting AC Compressor Issues:

Air compressors, like any piece of gear used frequently, should be checked and serviced regularly to guarantee optimal performance. Due to frequent and prolonged use, these equipment eventually break down. Here is a checklist to go over before calling in a professional HVAC specialist for more in-depth troubleshooting, repairs, and maintenance:

  • Possibly A Breaker Has Tripped:

Locate the air conditioner’s circuit breaker on the service panel. If the switch looks to have been tripped, turn it off and then on again. This should reset your control board and get your system back up and running.

  • Perform a Temperature Test:

Make sure that the batteries are still good and the thermostat is set to the right temperature. If the settings have been tampered with, your air conditioner may no longer function.

  • Pay Attention To Any Buzzing Sounds:

Head outdoors to the condenser unit while the system is kicking into gear. It’s possible that the start capacitor has to be replaced if the compressor is making noise but the system won’t come on. This component contains potentially dangerous and high voltages, so only a trained technician should replace it.

  • Hear If There Is A Clicking Sound:

Your air conditioner’s compressor will activate with a distinct clicking sound. The relay may be broken if the compressor won’t start, clicks repeatedly, or doesn’t click at all. Again, only a trained HVAC professional should attempt to replace this component.
