Your old aircon still worst as scrap metal. Sell it to scrap yard. You can get back some money.

I do that last time.

If without gas refill, the price is normal just like others non inverter service. Nothing special there.

I m not sure what is the price. Cause till now, I never refill since new installation. The service guy also don't have the gas too. Guess it stll not common yet.

The service guy told me no need refill everytime service. As long as the gas pressure remain spec. If need to refill everytime service, than the gas pipe got leaking.

What I can say is bullshit.

Sizing the aircon is very important from saving electricity to the lifespan of the aircon. A lot of people neglet this thing and brought the small aircon for big room to save cost. When longrun, it actually not save your wallet. It is my experience.


I m early adopter of inverter aircon. Have been using for 3yrs+ now. It reliable as normal aircon and the bill show me it save alot from my old aircon. The saving is enough for me to service the aircon every year without extra money from wallet compare normal aircon.

Not really. I place the outdoor unit ontop of the house at the open watertank area. It prompt to rain, storm, lightning and anything. No sign of rust or whatever. My old aircon too place at the same place for 9yrs. Too without showing any rust and corrod. 1 yrs 2x, I will spray the water into it to clean the condenser fin, to clean up the dirt.

Actually it is important to place the outdoor unit at the open space which have good air circulated. If the hot air can blow out fast and efficiency from the condenser, your compressor will run less too. The large open area is cooler compare small close area. It saving your bill.

Outdoor unit and the compressor is treated with antirust coat and paint. It won't get rust easilly. Most of the problem come from installation. Rough handling scratch off the paint and prompt to rust. The most easilly get rust is at the leg that mount the screw to the base. You will see alot of outdoor unit rust at the leg.

Quality servicing too will cause the unit problem. After open up and not install back properly will let the water sip in to the electronic part.


I would rather to pay more expensive servicing guy if he have a good quality servicing skill. Problem is, very hard to find. Specially like this new inverter aircon.

We have internet now. Do some research and understand it.

Inverter aircon is not new tech. Million of million people in first world counttry have been using it for many many yrs. Do they tell us that this inverter not recommend?

Old people have technology resistance. Cause still unknown to them. Even when you old, you too will have this phobia. Or is it our third world mind?

How you know your room size is enough for 1hp? Do you have some fomula to sizing? Or wild guess?

I don't know. I just use some fomula preset or data infor from website. There is a tons of infor in the net. You know uncle google right? Anyway, here in LY also have a lot of people helping you out.

I guess you know how to compare the infor in the net which one is right or wrong.

Each month I save around rm20-30 compare my previous bill. For 3yrs+. You do the math.

I m not inverter guys. Aircon inverter is my first use since it just arrived here. But I know this tech many yrs before arrive here. Just passion waiting.

Is it a bad smell? Probaly the water remain and infect with bacteria that cause the odour smaell.

If the gas leaking, it will continue leak till finish. It won't wait for you to on the aircon first.

Gas won't stop leaking even you on/off. It keep on leaking till finish. Either fast or slow depend on the hole.

It is most probaly the bad smell from the water leftover with bacteria infect. very common.

Is it the cracking sound start when the motor fan start to run? Probaly something touch the fan or the swing fin.

Sometime the cracking sound come after few min. That due to temperature different and some part expand and shrink.

This mostly aircon installation problem. The aircon didn't tilt slighty to the drain pipe side. Let the water gravity flow to the drain pipe.

This got to solve by the service guy.

Last time use to service the aircon by myself. You can see the dirty water and the slim at the water collection drainer. I don't know how many bacteria n there.

Nowaday when I clean the filter, I use the dettol to spray at the condenser to disinfect the fin and the drainer. Before putting back the filter.

I always wonder, does the air blow out contain bacteria or really clean.

He... I Not really that worry about bacteria. Some bacteria is not harm too.

With 8hr blowing everyday during sleep, 365day, I need to makesure the air as clean as possible. When I have flu or running nose that take time to cure, I will take extra measure to clean. Others time just normal filter clean.

Added on January 20, 2011, 3:47 pmI have those kind of filter. It is white color like fibre.

But it reduce the air flow and create a resistance to the blower.

Your blower is full of dust. That disturb and reduce the air flow. You need to do some servicing.

As long as the gas is still between pressure spec, you don't need to top up.

Check the manual for the piping lenght limitation.

Not just long run. Short run too will killing you with the bill.

Does your aircon come with the manual? Check the manual see what is the light mean.

I see alot of cassette type have water leaking after sometime running.

Yes, I see alot. Office or shopping centre with cassete type.

I m not sure is the design problem or the installation. This happen way back longtime even upstair my office have this water leaking problem using cassette type.

Not really. With schedule maintain, the leaking won't happen at all. The installation play a major part too.

Inverter and r410a gas is not new technology and has been using at others country many many yrs.

It only new in our country.
