8 Things that Can Happen Without Aircon Unit Maintenance and Check

Maintaining your aircon unit with the best aircon installation company in Singapore is very important, as if not maintained properly it could lead to costly repairs. If you follow some simple tips you can keep your aircon unit working for many more years.

Here are some of the problems that you might encounter if you don’t maintain and check your aircon unit:

1) Low refrigerant

It will result in a low oil level in the compressor bearing which will reduce the aircon unit’s cooling ability and in turn, will also cause leakage or damage to the aircon compressor.

2) Problems in condensers

This will result in low cooling or water leakage which can deactivate the safety device in the compressor and cause the service life of the aircon unit to be reduced.

3) Low gas pressure in the high side of a refrigeration system

It will result in the loss of cooling ability and the aircon unit compressor which can’t provide proper cooling in return due to higher gas pressure in the lower side of a refrigeration system.

4) Loss in cooling ability and compressor will run but not provide the required load

This will be your worst nightmare as your aircon unit will definitely not give you the kind of cool feeling that you’ve always wanted. You don’t want to be sweating all night and wake up feeling restless, right?

5) Engine oil can pollute the gas by producing carbon based or other materials

This in turn can affect the cooling capacity of your aircon unit. Not only that, but it is also harmful to your health since studies have shown that carbon emissions can worsen an allergic disease such as asthma and other respiratory diseases.

6) Motor winding damaged due to low voltage, over current, dirt accumulation

It will result in loss of power and control in the aircon unit compressor and might require you to replace your aircon unit even if it’s not the right time yet.

7) Water accumulation in the electrical motor or under the base plate.

Water accumulation can cause bearing damage and result in leakage from the pump resulting in loss of cooling capability and overheating of a compressor resulting in poor performance of the aircon unit.

Also, acid formation due to water leaking resulting in insufficient lubrication can result in low efficiency, gas pressure loss, and compressor can’t provide required cooling to the surrounding.

8) Loss of position indication in the compressor which is located by back contactors

This loss will give no signal to other control systems or other electrical parts of the chiller system causing under-performance of the whole chiller plant.

These are just some major problems identified due to poor maintenance which can affect the whole cooling unit of your aircon unit.
