Bubbling or hissing noise from the air conditioning unit

refrigerant work

Abnormally high electricity bill

These are signs that it's time to get
an aircon gas refill!

When the aircon gas level is low, air conditioners cant operate effectively and will have to work harder to maintain the desired temperatures.

Usually, the cooling chemicals inside the refrigerant storage of air conditioning units will not be entirely utilized throughout their service life.

More likely, though, low gas levels are caused by an aircon gas leak, especially if the aircon unit has never been serviced.

Why You Need to Top Up Aircon Gas

aircon gas top up

Air conditioners contain copper coils filled with refrigerant (aircon gas) to produce that cold air we love so much.

The refrigerant gas absorbs heat from the air, changing from a low-pressure gas to a high-pressure liquid. The other components of the air conditioner blow hot outdoor air over this cooling coil which rapidly cools the air, giving us cool comfort.

Unfortunately, your air conditioner can't produce this cooling effect if the aircon gas tank is low.


Aircon gas leaks are harmful to the environment if the chemicals get into the water system. Fortunately, you can minimise this possibility with regular aircon servicing.

Maintains energy efficiency

In general, better-maintained equipment will operate more effectively. A poorly maintained air conditioning unit uses more energy in order to function.

Prolongs lifespan of air conditioner

When the refrigerant storage leaks, the compressor can't cool down, causing it to eventually overheat and fail.

Ensures your aircon system is working properly

Sometimes, an aircon gas leak is caused by improper installation. A professional aircon technician can identify and fix leaks and any other problems in the air conditioner.
