Hi sifus, recently my aircon broke down. It was blowing normal/warm air instead of cool air.

I noticed that the compressor fan is still running, and the compressor sound is softer than usual.

It is an old aircon 1.5hp Panasonic aircon (CS-PC12EKH)... probably more than 10 years already. I managed to get someone to check. He told me is it time to change the whole aircon even though he has not done any checking.

Is there anything that I should or am able to check first?

Who is the someone ? Generally if you ask people, he will advise to change for a 10 years AC.....is oredi worth your investment ! All my Pana AC are above 10 years and still running. But if you have intention to replace another efficient AC invertor, then go ahead.

When wss the last time you did a full cleaning service? If you can find a technician who is willing to do the service now, then that is the first step you need to detect the fault.

If you are not a diy guy, then just clean the air filter and test again.

If that fails, you may need to clean the outdoor unit using a garden hose. If you cannot reach it, then DONT do it and wait for the AC technician.

That someone was an aircon technician. He came, took a look at the compressor (without opening it) and I think shaked it a bit (sorry, I wasn't around at that time to see), then the compressor started to work normally. However, a few days later the problem re-occurred.

The last full cleaning service was done on Sep 2019. After that no more because of Covid, didn't want unnecessary contact with outsiders.

I do clean the indoor unit filter regularly, so this should not be a problem.

For me, if possible, I would like to repair it instead of changing a new one, trying to minimise expenses. Also, not sure whether my current copper piping can support the newer inverter gas though. I heard that older piping may not be thick enough (sorry, that's what I heard, not sure how accurate is it).

Thank you all sifus for your views. I think I'll have to get another technician to check and repair if possible.

Mr CEO, my current AC uses the R22 gas. So, I'm not sure if it can support the R32 until I get a technician to check it out right?
