Mitsubishi Starmex Inverter Ac-Chemical Cleaning

[paopei 0]

We have our Mitsubishi Starmex inverter aircon about 2 yrs. We always clean the filter every 2 weeks and have general cleaning every 3 months. Yesterday after general cleaning, there is a bit noise "wush wush" from the blower. The service guy said that the aircon started to blocked and need chemical cleaning. But it is not even 2 years, so fast need chemical cleaning? Our daily usage about 10 hours and 12 hours for weekend. I thought if we have general cleaning every 3 months, the condition should be quite clean and no chemical cleaning needed until few years.

Another question, how long do we need to clean the compressor? cos the company that I signed contract with said that it is up to the technician to check whether need to clean compressor or not. I mean if the guy is lazy then he can just don't do it? Is there any rule like at least every 6 months must clean the compressor? what is the effect if compressor is dirty?

Thanks a lot for the reply cos I really have zero knowledge about this. Feel like the company that I have signed contract with for 2 years plus not really realiable. Quoted me $250 - 30 discount = $220 for chemical cleaning. I checked with other company is only $170-190 including topup gas R410. Feel disappointed cos just renew the contract yesterday. Haiz ...

Well...i did mine chemical cleaning after 2yrs as well...200 buck including gas for the same brand.The compressor needs to maintain the air flow otherwise the aircon will not function well...atleast not optimum i guess.

Why need top up? My understanding is that, if you need top up, there's a leak somewhere. Then, need to tackle the leak first, not topping up the gas first.

I am using the same air con, it's now two years. My situation is same as you, under service contract as well. So far the air con still working fine. My concern is the annual service contract $360, general service never clean the compressor so far. They service guy say can't clean, coz afraid downstair neighbor complaint. Ask me to spray water when it's raining. Is this matter? Just worry.
