Answer is NO. You can use your fridge for many years without having to top up gas. The same goes for your aircon.
When do you need to top up gas for your aircon?
Answer: Only when there are unsealed leakages in your air con system. If this happens, you need to seal the leaking area or get the leaking part replaced before topping up gas. Once the leaking area is sealed, you don’t need to top up gas until leaking happen again.
What are some common causes of gas leakages?
- Improper installation of your aircon.
- Poor quality copper pipe used.
- Chemical residue left over from improper chemical wash procedure causing corrosion in your air conditioning system.
Note that if your aircon is properly installed with quality piping and properly maintained, it is unlikely to have gas leakages. If there are leakages, you need to seal the leakage area to stop the leaking before topping up the gas.
There is no need to top up gas regularly unless there is unsealed leakages in your air conditioning system.
