I purchased MHI system 4 from GC at Changi Expo during promotion. Sales did not bother to check where I stay.
On installation day, technician found the compressor can not fit to MBR windows aircon ledge. Tried to call sales, no luck. Called and spoke with CS, they told me sales was off duty, and they end up pushed me to change with Panasonic brand, and told me, if I don't confirm on immediate, they will need to charge $150 for delaying installation.
I went to GC Sengkang for reporting the problem. One staff helped to make some call, and next day, sales called and arranged to change the aircon with Starmex system 4. I requested to change the technician with more senior one.
However, the next technician came even worst.
They did not cover my parquet floor, causing lots of scratches.
They also made one side of work desk in my common room broken on the alignment due to kena heavy pressure. And they also joint the cooper pipe, reasoning pipe already more than 15m. And worst, they did not bother to do vacuum for the piping. I called the sales and only being told to submit the feedback by email, which I did.
Different supervisor came to my house, to check and only apology for all the problem and promised to follow up with office today.
Just to share, so if you intend to get GC for your aircon, think twice. I am very disappointed.
I was quoted 3.3k for
Mitsubishi Electric Starmex MXY-3A28VA system 3 2700 btu inverter
Dunno g23 or 22 copper pipe
Replace new iron bracket for outdoor unit
Uninstall my 2 old indoor AirCon unit
How often to service your units is always dependent on your usage/environmental factors.
A rough guide would be that for daily users, it is recommended to service your units every 3-4 months. Especially for those with children/pets/smokers whereby the units will tend to get dirtier due to powder/fur/cigarette smoke
For the average users every 6 months and once a year for those that seldom use their units.
What you can do for self upkeep will be to wash your aircon filters regularly and also wipe the exterior of your units 1-2 times a week. Some brands allow easy removal of vanes etc that makes the upkeeping job easier.
What you can also do would be to ask your appointed contractor after your servicing how often would you need to service your units. They should be able assess the current condition of your units and advise accordingly for your consideration.
Hi if i want to change my system 4 unit. Can i keep the gas and water pipings and cables and just change the indoor and outdoor units as all items are inside trunking and some concealed. About 14 yrs old already.
If I may comment, quote is still reasonable,
I personally, I don't bother to spend more $$$ and even willing to give kopi money for the job done nicely, as appreciation.
But if you anyhow choose vendor based on cheapest one, you will risk the job not done properly, end up wasting your time and $$$ and more headache.
My suggestion is to check the quality of the vendor, rather than tempted with cheap proposal or sweet talk. And do not hesitate to ask question or to check when they carry out the job, to make sure you got what you already paid.
Its time to open it here on the table, which vendor is good, and which vendor is not good, so bad experience won't happen to other.
Let the vendor think, if their name and image are not good, because the way they carried the job not good, it is their option.
Remember, people talk based on their experience.
