system 2 aircon very simple and direct job, no matter you buy from Gain City/Best Tech/Cool World, their installer also can do a good job for you..if only install 2 unit aircon their installer also cant install well then they can close their business ady

Bad Experience with Gain City

It clearly states Gauge 22 in the invoice, and the sales man ran through with me at the Store after the invoice was printed. Today during installation, they say the salesman typo it's Gauge 23 instead. "Standard Package etc".

Seems like a standard Bait and switch tactic.

Salesman also said I can either retain my current unit or they can help to dispose. No extra charges.

Today during installation, installer says they will charge if we wish to retain the current unit.

Be careful with unscrupulous salesmen with Gain City, run through and record the conversation with them and go through the invoice carefully. Eventually settled for keeping the air con without additional charges, but really disappointing to see this from an established big retailer.

Just go with any small shops instead. I feel quite cheated..

Hi, need recommendations for replacing current system 3 aircon. Current I have "Mitsubishi electric" Starmex installed. Horrible experience with aircon itself and craftsmanship from the shop.

Replaced starting capacitor
Replaced control board TWICE
Bolt and nuts problem and caused leaking
One fan coil dead
Pipe is leaking here and there

All happened after just 5 years of warranty.

Want to find out:
1) want to have a 5 ticks outdoor unit with the longest warranty
2) a good installation service on scraping current system and install the new system with the longest warranty

Thanks for any suggestion!

Just finished my aircon installation on 17 Nov 2015. My experience is as follows
Initially I sourced 3 quotes for a Mitsubishi Electric system which consists of :-
MXY-2E20VA + 2 x MSY-GE13VA &
MXY-3A28VA + MSY-GE13VA + MSY-GE18VA
Installation includes :-
•22SWG (1/4”) copper pipe (new)
•Separate 3/4" Armaflex insulation for gas and discharge pipe
•16mm diameter PVC water drainage pipe with 1/4'' insulation
•Replacement/ patch up of false ceiling

The 3 quotes I received were Newway Systems $6,500, Gain City $6,728 and another contractor recommended by a Bro in the forum here $9,000.

Only the forum recommended contractor and Newway System did the site survey, Gain City appointment for site survey was fully booked until the following month. I paid $60 for the site survey by Newway System which was offset subsequently when I awarded the job to them. Nothing to shout about forum recommended contractor's site survey as he just ask where you want to place the aircon and he just quote accordingly to what I want.

For Newway system, he could tell me that the original aircon layout in my place was incorrect and recommended me where the correct placement should be. He also recommend me to take Mitsubishi Heavy Industries rather than Mitsubishi Elect aircon as he has been servicing quite a number of PCB board failure in Mitsubishi Electric Aircon. He recommended me the following instead:-
MITSUBISHI HEAVY System 2 (SCM60ZJS (BTU25,590)/ SRK35ZM (BTU12,000) X 2)-$2,600
MITSUBISHI HEAVY System 1 (SRK/SRC71 ZM-S) BTU24,300- $2,300
Labour Charges - $900.
Total was around $5,992 after discount and reimbursed survey fees.

The installation took about 1.25 days. Overall I'm very satisfied with their work.

Daikin 4mk90hvec8, is it a R22 or R410 system ?

After doing some research I realised that R22 system is phasing out so I intend to replace my Daikin (almost 10 years old).

Question is do I need to redo the piping ? Understand R22 and R410 piping are not compatible due to different specification.

Any expert out there to shed some light ?

If walls concealed then high pressure test will do.
If just running with trunking then 100% from my suggestion to be redo and remove all, then replace with all new.

Cause the old insulation can't take the R410a gas and cooling condensation anyway.

The only way new insulation can be prevent water condensation in pipeline with new insulation as well.

Why so? What alternative value for money brands do you recommend then?
