I beg to differ with Antara. I recently requested them to do general maintenance on my aircon. They just did some cleaning, which is fine. However, one of the unit is not warm after the servicing, so asked them down again to look at it. Just said it was insufficient gas and pumped some gas. That same night, the unit was warm again, so called them back. This time, they wanted to pump more gas but I insisted they troubleshoot further, and eventually isolated the fault to some valve. Already paid them for the troubleshooting over $100, and then they quoted $180 to fix the issue with the spare parts - claiming that they are just charging for the spare parts since they already got paid for the servicing. Called Daikin and the equal spare parts is $84, plus $80 for service cost, with one month warranty. So, kind of regretting it now... should have called Daikin straight off and have the problem fixed at $160+, instead of now spending over $300 over 3 trips for Antara. Not very honest in their dealings with me, imho.
