System 4 aircon piping

[Kelvingoh45]

Aircon at home fail so went down to Courts,the salesman there tell me that if my existing piping is conceal behine warobe or floor ceilling,they will not be able to change.The price of the system 4 aircon will still be the same even without piping changed.

 

Will the performance of the new aircon be affected if piping are not change?

What are the recomended brands for aircon. Mitsubishi,Carrier,Toshiba?

Currently my system 3 also spoilt after 10 years. Upgrade to Mitsubishi System 4. I bypass all the major store and go direct to a aircon installation shop. Major store offer the BTU is lesser. I manage to get a 34000 BTU for HDB flat. Individual is 10,000 btu and the hall is 24000btu.

 

All wiring and piping change new. If u are from 3 to 4, the bigger unit piping is different size.

 

If I just change my compressor but keep the blower, they say No gurantee.

have to change...

 

otherwise lots of problem down the line...

 

leakage... insulation will deteriorate over time... etc...

 

no point just change compressor without changing pipe

not sure how old is your aircon, but now they are using a slightly bigger piping (in diameter i meant)....

 

better to change everything. why not go Safe superstore to ask for quotation

in short, in "feng" of piping they use in market they call.. 3 feng or 5 feng etc etc kind

I kenna the same problem recently. Unless you have the wet vacuum cleaner then you can DIY. Just suck the dirt out from the water outlet pipe. It's clogging the pipe. Else better to call the aircon guy. I call this guy who did my aircon for $30. Took out the whole unit to clean and also use the vacuum cleaner to suck from the outlet pipe.

A ugly DIY method is to do a bypass from the fancoil output directly and pipe the tube to a pail on the floor. But must remember to empty the pail every morning.

I had been using those aircon cleaner foam [in aerosol can]. The foam will clean the coils/fins in the room units, and will also loosen those "algae" that accumulate in the pipings, especially at the room unit drain hole.

These aircon cleaners are available in Mustafa, Homely Hardware, ........

You can give a try. Simply follow the instructions on the can.

At IMM, I keep seeing this pushcart that sells such cleaners - Mckenzie or something...

 

Anyway, my aircon guy will use compressed air to clear the pipes every 6 months when he comes over to service my aircons...

 

But my system 4 (McQuay) is coming to 10 years old and will need to replace them soon...
