Need to warn ppl here about c&d aircon services (if they are reading this, you know who I am)
Air con problem: Auto shut down + not cold + Blinking light
Talk about good thing first: Fast response, fast activation possible to come down on same day.
Bad:
First visit: Technician came down, told him that aircon auto switch off after 15-20 min and not cold, technician take remote control switch it on and checked compressor, say aircon very dirty and if still auto shut down pls book appointment for chemical wash and he left. Subsquently, aircon still switched off automatically and I contacted their boss to feedback and the technician just called back to say pls book chemical wash. $40 for transport.
Next day, called back to make appointment for chemical wash, did some research to see if it is necessary since they other checks were done, and found out maybe circuit board might be the reason, so called back just to enquire if they might do a check to see if it might be that problem instead, if not just do chemical wash for nothing??? So the boss said, usually technician will recommend a chemical wash first and then if it doesn't solve the problem then they might need to check again (means more money to pay la???) But nevermind, still book with chemical wash with them and say that they will still do a check before proceeding but usually machine this kind of thing no guarantee one they can only start by doing the basic repair first (in this case, chemical wash)
Fast forward to the day they suppose to come down for chemical wash, boss called say she further discuss with the technician and technician told her "AIRCON NOT VERY DIRTY"(previously he said VERY DIRTY) so probability of circuit board spoil higher than because of dirty. (What????) End up say how about that day just change circuit board straight? LOL
Told them don't need come down in the end.
So if I never call and ask if it might be the circuit board, then they will just come down and do chemical wash?? But now I tell them about circuit board, immediately say might be circuit board problem? Change circuit board ($190) vs Chemical wash ($100).
Not sure about you, but it sure sounds like a shady work to me.
Also, recommend Aircon Uncle, though their slots are harder to book, they came over and did a diagnostic by checking the compressor, and because I don't stay in that house I have no idea what repair has been done before, the technicians did a trial and error to find out what is the problem. Turns out that it was the wiring! So if I had went forward to do chemical wash ($100) / change the circuit board ($190), the aircon will still not be fixed!
TL;DR Avoid C&D air con, 10/10 recommend aircon uncle.
