8 Signs of Non-Functional Aircon Compressors

An aircon compressor is a delicate mechanism and will eventually break down. There are certain telltale signs that indicate when it’s time to have your aircon system repaired. While a broken aircon compressor may not indicate that you need to replace the entire unit, there are some warning signs that you should be aware of.

Here are 8 signs of non-functional aircon compressors:

1) Abnormally high power consumption and/or noise.

A unit that’s struggling will often draw more power than it normally would as it attempts to maintain the same level of comfort output. This may also manifest as a high-pitched or “whining” noise as the system attempts to compensate for a lack of cooling effect.

2) Frequent compressor shut-offs or other shutdowns.

If you notice that your unit is turning off abruptly, this could mean you need a new compressor. The loss in power output will cause the thermostat to trigger an emergency stop so it can re-acquire the cooling effect.

3) Leaking refrigerant.

The condenser and evaporator coils may start to leak out their coolants, rendering your unit nearly useless. While this is a serious problem that requires professional attention, it’s indicative of other issues such as an improper charge or a defective compressor that has failed due to the strain of pumping out the leaking coolant.

4) Loss of cooling effect.

If you notice that your aircon system isn’t as cold as it used to be, this could indicate a partially failed compressor or an undercharged unit. In both cases, the compressor is still working but not as efficiently as it should.

5) It’s been more than three years.

Most manufacturers recommend that their units are serviced every three years. If you haven’t had your unit checked in more than 3 years, it would be wise to do so.

6) The exterior of the unit is soiled with dirt or debris.

This could be caused by overcharges which have damaged the compressor’s core, rendering it unable to circulate refrigerant properly.

7) Branches or other debris are obstructing the fins of the condenser.

Debris, like leaves and branches that would ordinarily pass through your window screen create an effective insulation barrier against your unit’s cooling capacity. Check for this problem before calling in a technician; it could be easily resolved with a simple cleaning.

8) Frequent power outages.

If your unit is frequently shutting down due to sudden blackouts, this could mean the compressor’s starter capacitor isn’t keeping up with its workload. This problem can be resolved by replacing the old capacitor with a new, upgraded version.

It’s always a good time to talk about the common issues that aircon units have.
