I am considering between a 9k BTU and 12k BTU for a normal size bedroom. Which one saves more money in the long run in terms of power bill?

Assuming that I on for 10 hours a day on 24 degrees. I dont need to cool the room rapidly, just want to balance my comfort with the cost i am paying

To MightyPigeon,

If ur room is < 15 square metres, 9k is sufficient.

Installed a brand new system 1 by Gain City 2 weeks ago.

Model: Mit Electric StarMex 12K

Today morning woke up and found a small part of the pipe/trunking with condensation although it didn't drop on the floor but I smell trouble coming up.

AC is still very powerful though. I set it to 19 Degree to sleep didn't notice any difference since day 1. Still as cold.

Gave Gain City a call today and they will be sending down a technician to do a check on 291214.

Very disappointed. AC is only 2 weeks old only and it is giving this kind of problem

Material used for installation all is upgraded

Armaflex - 1/2
UPG Copper - G22
Drainage Pipe 16mm
Inverter it kind couldn't over cooling as below 20C, then you force the compressor runs till non stop and the water dripping inside the trucking could be created bad smell on water, that is normal.

If you can open the trucking and cut smaller piece of rubber foam inside all are water, store all water can be use as a hose already, lol

Toshiba Air Con

Hi,

Any one used Toshiba air con before? Is it good?

For trunking, anyone knows if the drilling can be done in the reinforced walls (not the partition walls)?

Thanks in advance!

Paid deposit to Best Tech last weekend and now very worried after seeing so many bad reviews on them.

Need some advise from you guys:

1. Mitsubishi Starmex or Toshiba? (Saw some advise is Toshiba is actually overpriced?)

2. Free update to Yamato 3/8 Piping. (Should i request to change to Armaflex insulation instead?)

Hi Terumo

Appreciate if you can advise:

1) what are the various amp points available and charges? What is it for or rather how does it equip to which ever system?

2) what is the differences between Mitsubishi Heavy industries vs Starmex?

Many thanks!
MHI is a separate company vs mit electric. they have its own R&D and independent. in some country MHI advertise as its own brand " MHI" and in some country know as " beaver". The aircon are made in Thailand.

To chiqing,

Mit Electric is more value for money compared to Toshiba.

I will prefer Armaflex. Seems like Yamato, only certain companies are using.

Even most aircon materials supplier are not selling it.

Thanks. So Armaflex the normal 3/8" is ok? Or upgrade to 1/2" is better?

To chiqing,

1/2 is neccessary if your piping is hidden.
If in trunking, its good to have.

Need help troubleshooting my aircon system.

Mitsubishi starmex
Indoor unit turned on, but fan stops after about 1 min with the ops top led flashing, bottom led off.

What could be the problem? The 2 other split units work without problem.

Try to remove air vent up & down, after put back and test again.
