All About Aircon (New, Maintenance, related components)

ltn:

Let me post my honest encounter with coolserve.


1. One of my air cond unit was choked and hence water was leaking
2. I called Coolserve and told them to clear the choke and advise my wife how much it cost for yearly contract so we can decide on the spot.
3. I was traveling for business hence not in town.

The uneducated technician came and started working on all the other air con unit ... wife called me and i asked him to stop and just clear 1 unit and i know the price is 150. The guy proceed to clean the unit and then started saying compressor gas was low and need refilling, even said that the 3M filter i am using will damage my air cond hence recommend his charcoal filters.. and telling all sorts of things to my wife. End of the day the bill was 500-600 bucks!

I called the customer service when i got back and the ah lian on the other line just entertained me and gave a smirk in her tone of voice. I swear if i was there on that day the technician would have his ass kicked back to JB

PLEASE THINK TWICE Before engaging COOLSERVE

From previous experience, i do not sign contracts with aircon compannies. I tell them that if i need to assess their service first before deciding. Anyway i think 3 monthly servicing of air con is not necessary if you clean it frequently on your own. If they need to do more, as in your case, i will always ask them what is the total amount including all the labour charges and gst before deciding. If it is too expensive, i will tell them that i will need to discuss with hubby and may also need to get 2nd opinion.

BMy hb’s friend is our ac supply & install guy.


At my previous place, it was a Daikin installed by previous tenants. Around 6 years old system 3.
Always got Problem! But the guy only charge us $70 per visit.

Then when we got our new house, we ask him for quote. Slightly more exp than outside but he gave us the best insulator n piping plus his workmanship is very good. Even my neighbours decided to get him to install their ac after they saw ours.

Best to get someone reliable who won’t cheat you.

Yeah... I also wonder if the brand has anything to do with aircon problems. I used to have a National split unit with 3 blowers - and 2 always on daily. Yet I have ZERO leakage problems with it... only need to top up coolent on an annual basis. My current set is pre-installed by the condo - Daikin. Problems started with 6 months on us moving in. What are your experiences with air-con brands?

[corneyAmber]

I used to have 3 split units, National also I think and after 3 years still good, 2 of which commonly used.


Now I have Daikin, also pre-installed. First 5 years ok, then 2 started to leak, 2 rotating motors for the vent out of order, 1 had to change the motherboard, then compressor also changed piping and themister…chemical wash twice…everything happened in the second 5 years. But all these years we have yearly maintenance contract. Is this normal?

[mrswongtuition]

Our ac guy recommended other brands to us, told us not to take Daikin.


We currently have Panasonic. Find it very good. My parent’s place also using the same model. Cools the room very quickly and my electrical bill is not sky high though we on the aircon almost the whole day.

We are using Toshiba. It is only 1.5 yrs old. The unit in our room leaked and we realised that it could be the way the piping was run.... sorry layman... something to the effect that my contractor probably did not slant the pipe enough so the water would backflow back.... We do have this probably once in a while.


For our old house, the developer installed Mcquay. It served us well for 8 years. It is currently tenanted out to a american couple who turns on the aircon 24/7. Last year they called us saying that our living room unit \"rained\" when the wife was out fetching the hubby from the airport.... So our false wall,etc... at that area was soaked with water. The other contractors came with quotes that need to heck off the false wall to enable easy servicing,etc... but we called in the guy who has always done it for us. We supposed he got it fixed with all the chemical wash,etc..... so now our tenant is using that guy for servicing as well. :xedfingers: We've not heard anything hopefully.... it is fine now. But we supposed when they leave, we probably need to replace the units due to their super heavy usage. :!:

My mum's house also using panansonic and so far so good.

I am also using Toshiba currently. It’s about 7+ years already and a 3-room split unit. Only two are used every night while the other one only once in a while. So far so good touch wood. I’ve had it chemical cleaned once only. The rest of the time general cleaning on an adhoc basis, once a year.


Does anyone know what’s the average lifespan of an aircon? From what I’ve read here, no one has had their aircon for more than 10 years. Is the lifespan about 7 years? I would dread having to change the whole thing cos a colleague of mine recently had her 3 room split unit changed and it took two technicians and a whole day!

Hi, how long do you service your aircon?

Everytime I tried to use , it was not cold at all.
the last service is around 4-5 mths ago and i had just use only twice after servicing. And now it was not cold at all. Anyone had this experience before? Anyone use portable aircon ? It is effecient?

is there any leakage?

otherwise you can try to turn off everything, take out the plug wait for a few minutes and turn on the air con again. if its not cold, you should call the guys who service your aircon earlier.

I am not sure of the leakage. How to check the leakage ?

Thanks
