OMG, i was wondering whether anyone had the same experience with Sky Blue. we didn't sign a contract with them, but knew it was time for an aircon service and called Sky Blue. They told us the same exact issue, that they all needed chemical treatment and to be regassed it was going to cost $1500 for the 5 aircons. I agreed to 2 of them, the ones with the most usage being done and with their servicing of all the others I paid $900 all up.
A few weeks later, I was told by others in our condo
thet were told the same thing and people have been paying upwards of $1000 with them. Our condo is only about 2-3 years old, so why all the aircons need such serious treatment.
About 2 months after above treatment, one of the aircons chemically treated broke down and the other one also chemically treated started leaking a few weeks after. They came out to take a look again as they were still under service warranty and told me they needed another clean (and another payment). I refused. They then said the one which had broken down needed a new computer board at a cost of $1200. I kicked them out of the apartment, rang our landlord who put us onto another company to come and take a look as to why they were leaking and not working. Both were fixed quickly at a cost to our landllord who covered it given the prior problems at $80, no new board needed.
On top of that Sky Blue stuck their stickers all over our aircons both inside the apartment and on the outside units without asking. They also spam our condo with flyers weekly.
Avoid them at all cost (literally).
