Air conditioning - Any recommendations please??

[kimsim]

Hi guys, I'm looking for either Mitsubishi Starmex system 3 inverter or Daikin system 3 inverter for my HDB resale flat. 9000 BTU for each unit.

I went to Gain City and All Best at IMM.

Gain City (total price is $3448)
- Air Con $3169
- Additional warranty for 5 years for blower and all parts $99
- Upgrade pipes to bigger pipes $180

All Best (total price is $3098)
- Air Con $2799
- Additional warranty for 5 years for blower and all parts $299
- Pipes are already 16mm bigger pipes
- Provides workmanship warranty that covers everything including condensation and any issues for 5 years

Which one should I go for? Or are there any other shops you guys recommend? Thanks in advance!

All Best still much cheaper I guess, cause my unit also from All Best.

Please check the bracket & Dismantle the old unit are included, if you have

New aircon installation

Hi

I need to change to new aircon, but getting different feedback on changing the new piping. SOme say new aircon must use new piping due to diff gas use, but others say condo aircon piping are very good and need not change. My aircon is 15 years old and now in dilema - daikin or mitsubishi> New pipe or old pipe? Gain city quoted $1k+ for installation and change new piping.

15 years old better to change piping.. but is any of it concealed? if concealed the cost will be more..

Why 10% old pipe cause the place inaccessible for replacement? mostly cause by the old pipe cause it can't handle R410 gas pressure. (2x the R22 gas pressure). The pipe crack hole become larger n larger so the gas leak will become faster overtime...

10% old pipe inaccessible as its covered-up, & I didn't want to open up 4yrs back when installing the new aircon. Thanks.

Will be relaying the piping, need some help with the recommended sizes

My setup:
StartMex Sys4 - MXY4A28VA, MSY-GE10VA x3, MSY-GE26VA x1

According to the manuals,
pipe diameter liquid/gas (thickness)
GE10VA, 9.52/6.35(0.8)
GE26VA , 15.88/9.52(1/0.8)

Am I correct to interpret as
GE10VA, drain pipe diameter 9.52, copper pipe diameter 6.35, both thickness 0.8.?

GE26VA, drain pipe diameter 15.88 thickness 1.0, copper pipe diameter 9.52, thickness 0.8?

Insulation thickness, as per terumo's post #6000, pg400.
For 9k/12k btu for Mitsubishi, the pipe size should be 1/4 & 3/8.
For 18k should be 1/4 & 1/2.
24k btu should be 3/8 & 5/8.

Advice appreciated, thanks.

Hi RedCon,

Please quote

HDB 4 room.
Mitsubishi Starmax, MXY3A28VA + MSYGE10VA x 3
Copper pipes, Grade 23 (0.61mm)
Do you use pipe benders for corners?
Class 0 insulation, 1/2"(12.7mm), Amarflex or Thermaflex
PVC piping 16mm
3C40 wire for outdoor
3C70 wire for indoor
Is there any length limit to the supplied material?
GST included, parts & labour too.
I would assume installation is by BCA certified personnel.

Thanks alot.

pipe size r right. copper ask to use 22swg thickness for R410 gas. insulation amaflex brand 1/2 inch thickness

Why 22SWG?
Mitsu manuals says 0.8mm thickness, shouldn't it be 21SWG according to SWG Wiki ?

Thickness not too important, but the insulation of rubber foam most important than used G23 copper pipe, if the PVC pipe didn't cover with rubber foam at all.

The water dripping would be an issue too.

Recommendation for air-con

Hi,

My unit is a HDB 3-room flat, and I intend to install air con to the master room and common room, what are your recommendations for best cost saving, budget $2,500 and below, this unit has never installed any air con before so please quote all inclusive.

Thanks.

I don't get what you mean by "PVC didn't cover with rubber foam at all". Are you saying PVC drain pipe should be insulated?

Yap, even PVC pipe should cover with insulated rubber foam.. To avoid water dripping after 3-6 mths usage time, cause has many similar case was the PVC drain outlet pipe didn't cover foam at all.

The bottom part of trucking can see a lot water yellow marks or some may water dripping down already.

Sales introduce lg but I think he want to hit quota lah since seldom hear ppl use lg.. Then Mitsubishi is I ask then he say one... Looking for lsystem 2 msyge10va n 2e20va compressor(or do I need 3a28va?)

 

[terumo]

To bananaboat,
$2.5k can get you a system 2 with installation and the necessary power supply.
Do not worry.

 

[terumo]

To streakin,

I suggest you look at Mitsubishi Electric, Toshiba & Daikin and steer away from the rest of the brands.
Living room will require 24k btu while the rest of the rooms 9k btu.
