Need some advice, for me, heavy user, 3 bed room on every night and living room occasionally.

I decided to go with ME system 4 for my new house. 2 ticks 4A38VA compressor and 9k for 2 bedroom and 12k for master and 18k for living. One of my Aircon guy quoted me $4.4k for armaflex class 0 1/2" insulation, 22SWG copper pipes, 16mm drainage pipes, keystone cables and 2 trip install, which I find, is reasonable.

Then when I ask him how much for the 5 ticks 4G38VA version same btu config (FJ series) for rooms, he like very reluctant to quote me, and just tell me $6500 for the 5 tick version which is think is BS and he just anyhow pluck number from thin air one.. why ah? 2 tick profit margin higher issit?
Get Lg better, they have 3-5 ticks compressor u can choose n 5 years warranty on parts. Or mhi. Have ioniser

Try aircon 101 for quote if u can pay cash or chq. Ask for quote based on group bto buy https://m.facebook.com/Aircon101p/

4rm hdb will take sys4 or 3+1 or 2+2(daikin 5tick no sys1??)
2+2 better. Alot of system 2 has good ticks rating. Can be cheaper than system 4

My parent home, whole trunking from toilet to room has water condensation. Quite jialat. Is it because frequent usage?

Using me. Suck big time. Compressor unit got problem in 3 + years. Not covered by warranty. Also fcu keep breaking down or not cold.
Trunking no matter to wat brand of sys. Its the insulation quality. Most cases are insulation choked with aglae or moss or fungi and hence insulation is gone and hence water condensation happened.

Frequent usage is the main cause of all problems. No choice, eventually wear and tear comes in and regular servicing is require.

A qualified installation personnel is as important as selecting the right air conditioner.

So, you had spent much time understanding the types of system and brands that you need to purchase as well as the types of material required for a lasting and efficient system.

Having the correct hardware is important but having a skilled person to install the hardware is equally important for the whole system to operate effectively.

There are many air conditioning companies in Singapore but there are even more people doing air conditioner installation and maintenance.

How do the public check that the person doing the installation and/or maintenance has the proper air conditioning training to do the job? Can anyone help?

First - Big com or what? very likely BS.
Second - How many units u have were cleaned? Which one with chemical and which one with take down?
third - if $400 for a sys4 chemical cleaning plus takedown, gas top-up and compressor cleaning isn't expensive
Fourth - Ur bedroom unit likely choke up dirt in fan coil which chemical cleaning have no effect
fifth - dun believe even the next 2 companies, they are BSing you abt the chemical wash.

General Guide when ordering for your cleaning of AC:

General Cleaning - $20 per unit? No sure market rate now - "general" vaccum and brushing of dirt and grime of cooling coil and fan coil. Not thorough one.
Chemical cleaning - 40-50 per unit? cleaning the cooling coil and drainage only from grime and dirt. Quite thorough for the cooling coil.
Takedown cleaning - $200-250 per unit? Removing blower from wall will be able to clean the fan coil. Need to top-up gas. (exception of starmex GE series)
Compressor cleaning - $40? Flushing the fan and condenser with clean water, remove dirt only
Refrigerant top-up - $100-$150? Especially needed when a takedown cleaning is done.

Rule of Thumb - Google and read to know more...

I think the same guys came to my place a few years back and tried to jack up the pricing too in the same method. But we rejected them as we did not feel comfortable with them. They broke my aircon cover and went off just like that.

Last time I cheapskate. Took up those cheapo groupon aircon servicing deals.

The guys are totally not professional. Broke my aircon cover and never confess on that day.

1 week later, I found out. I went to their Facebook page and blast them.

Thereafter, they sent someone down with a new cover replacement.

That was the last straw. I will never engage Groupon listed aircon servicing companies.

Aircon 101

Just checking. Has anyone purchased their new aircon from Aircon 101? Any comments / experience to share? What are the materials that they provide and are you happy with their services and any problem encountered?

I am looking to purchase from them. Called their hotline but no one answer the call. Feeling a little concern about this!

To Boopit. You mentioned M. Starmex system 4. But what model? Your house has 3 bedrooms + 1 living room. How you want to allocate your 4 FCUs?

Hi Boopit. The FJ series is the latest if I am not wrong. Price not bad but depends whether supplier cuts corners during installation. The installation of an air conditioner is as important as the effectiveness of the air conditioner itself.

Theoretically, the BTU is fine for the living room with that size (if I am not wrong) but the location of the FCU may be affected by the "L" shape of the living room. So there may be hot spot. It also depends on the number of people in the living room when using the air conditioner as well as what is the activity there (more active activity and more people would mean more heat), and whether the TV is turned on and what type and size of the TV. Furthermore, part of the living room would likely be used as a dinning place and therefore the kitchen door may likely be opened frequently. In the end, it depends also on the temperature that you are comfortable with. Some people feels fine with 25 degree while others need 20 degree. Alternatively, a ceiling fan installed at the right place can help circulation as well as cools the body. I understand that there are suppliers who my provide a large FCU of 18K BTU and three 9K BTU for the system 4. But you need to check whether there is any advantage of doing so. Over sizing the system is not good for cooling, comfort and economical effectiveness. The above are my option. Let's see what others have to advise.
