Anyone can recommend me good contractor to install air con?

Why people like to buy a aircon without a installer?

Cheaper?

what synthetic refrigerant additive available for R410a system in our local market?

My house need to do installation from living room to backyard which is not standard installation as you buy from air con package less than 10 ft length. A lot hacking and conceal need to do and normal installer won't entertain you and is not you like or not like.

make sense

You can tell them what you want and where to place. The extra installation work need extra charge from the std installation.

I go through 2 installation which is not std. Conseal and more than 10ft piping. As I require the outdoor unit to be place ontop the roof water tank area.

No problem for the installer and no complain.

Is it you're not agree with the price ?

agree..i always set the temp between 26-27..for my case i used the aircond daily around 6pm until 7.00am the next day..using hitachi inverter 1hp..1st bill around 80ringgit

I Don't read all the thread post but i have a question. How to reduce your electric bill but at the same time you frequently on your aircond. I just install 1HP aircond since January 2017 at my bedroom. At February,March i only pay RM30++ because i only set the temperate between 24-27 degree celcius. But when April's electric bill come, i shocked a lil bit because the bill shows RM90++ since i did'nt change the temperature. Fyi i only on my aircond at night only. So how to fix ?

How much was the electric bill before February?
I think sometimes TNB uses "anggaran" based on previous readings so the bill is not so accurate. But after that they will adjust again for new usage (your new aircon) based on actual reading. So the April bill may cover what was under charged by TNB in Feb and March.

Hi, For those who as wall unit in their bedroom and uses it every night. how often do you call for cleaning services in a year? I have to do it every 3-4 months.

Every 3-4 months is like too frequent. Normal frequency should be around once per year only.

Is your area very dusty?

its a housing area where its away from any big main roads and there's not that many cars that passes by. Only one unit out of 5 others in my house needs servicing that frequently and I'm using an inverter unit.

after 5 months, the room will no longer be cold despite it being on low temp and full blast

Paying for cleaning service that frequently is rather expensive so Im still trying to find out the cause of it and I am contemplating buying a new non inverter unit all together. serving that unit 3-4 times a year for 2 years is enough to buy a new unit d for 1 HP

Is your air con correctly sized? Seemed to me either an undersized air con or faulty unit. Shouldn't need that frequent servicing.

Also did you clean the indoor filter regularly? Like every two weeks.

its a small room and i have the air con unit blowing straight at my desk yet i'm still sweating under it
and yes I do clean the indoor filter regularly 3-4 weeks once but it doesn't solve my problem. It has been like this for more than year and I service my aircon every 4-5 months when i can't stand it anymore cuz its really really hot.

It will be cold for a month or so after cleaning with only low speed required. after a month i'll have to turn up the fan speed gradually .

you recon that the unit is faulty? should i just go ahead and buy a new one.

Another possibility is the refrigerant is leaking somewhere. When the contractor came for servicing, did they mention about gas leak? Do they need to top up the gas for you every time they do servicing?

Is your drain pipe correct installed? Should be slightly slanted to drain the condensate to outdoor.

Buying a new one seemed like the last resort. I would recommend you to troubleshoot your current unit first.

I had 2 different contractors to do the cleaning for me for 2 years and all said that there's nothing wrong with the unit and no need to top up the gas. They just mentioned that its dirty and its normal to clean every 3-4 months maybe just to charge me more for cleaning frequently.

January bill still RM30++. I've wondered if my aircond need to be service. I use SHARP Brand with inverter.

anyone can help? I'm looking for a reliable air con person. My area is Puchong. Appreciate if anyone could recommend a great and reliable air con person. All my previous air con people are utterly useless

Mostly can last nore than 10yrs.

Mind already 9yrs+.

What's wrong with that?

Why related the gas with the aircon lifespan?

Aircon don't require to pump gas in every service or every yrs.

R22 gas will be phase out cause depleted the ozone. Your responsible to takecare the enviroment. It is volunteer you want to do it or not.

Even it replace by R410, it is not totally gone for the R22 gas. It will cost higher since in the market getting less. Till the manufacturing totally no more produce r22 type aircon.

I knew this phase out since 16yrs ago. And my 9yrs+ aircon is using R410.

Never top up or low gas pressure since install time.

If tomorrow they told me no more r410 gas, it doesn't matter to me.
