All About Aircon (New, Maintenance, related components)

[atrecord]

if you wanna know about portable aircon, i posted quite an elaborate piece in an earlier mail a few weeks back, think the thread is called ‘portable aircon’.


as for the split unit, i do not use it all the time. for the kids, we’ll use the aircon for about 40 min every night when they first go to bed, then after that no more - unless it’s really hot and they make noise in the middle of the night, then maybe another half hour.

our aircon is 10-yr old now. before kids came along in 03, we hardly used it, and when we did the first servicing in 02, the technician went through the whole process, and commented there was almost no dust/dirt, so it could have been money wasted.

subsequently, we had i think 2 more servicings done, the last of which was i think 3 yr ago… which reminds me that it’s perhaps time to have another one again.

but so far, it’s still cool although maybe not as good as before.

oh, i’ll clean the filter and vacuum the coil myself everytime the indicator light comes on. so that could have helped (slightly) it stay cool.

so far only had one instance where some part in one of the blower conked off, and we had to have it replaced, cost $100+.

Anyone has good recommendation for air-con servicing. Could you PM me…Thanks

1. Usually how long can a aircon last. I mean those with a compress and multi-split not portable ones.


2. Can we service our own aircon? I feel is not that difficult whenever I saw the servicemen doing it. Any opinion?

1. My airon has been 10 years. So far only changed the unit in my room once about 3 years ago. I have 4 units split, the rest of the splits are still fine.

2. Yes, hubby and I have done so a few times. Its not difficult, as long as you know how to dismantle and put it back. The most tedious part is the cleaning of the drum. We don't know how to take out the drum, hence use a brush and vacuum cleaner to brush out the thick dirt. One unit takes us about 2 hours to brush the drum, spray the foam on the metal coil, wash the filter.

We also clean our own like what you have described in your earlier post.

but the topping up of the gas and/or chemical wash, still need a technician.

Thanks for all the advice. But why my air con unit is still not cool since I just top up the units less than 6 mths ago and I didnot use it for more than 3 times since topping up. Do air con need to be on weekly or daily on to have a smooth function?

[shurley197323]

Bt the way, if we change the whole unit, that means we had to tear down all the wires and reconnect new wires ? For those who had change the air con before, won’t that be a mess?

[shurley197323]

Dear daisyt, how they change the single unit in your room? Do you bought the same unit ? Because mine is a resale flat with 3 units of aircon but I wish to change / use only 2 units. And I was worried about all the hidden cables -

by right, no need. your aircon should still be cold even if you seldom use it.
