Isis aircon repaired, bought replacement filters
The Isis aircon was really down. YowCH sent the car for assessment at Tomika (Alexandra Village, Bukit Merah) on 5 Feb and Mr Lee, the boss, checked that all the gas recently topped up is gone! Given that the cabin temperature is hot, it would be the evaporator (coils) leaking, which needs 5 hours to repair. Quoted $480 before GST.
Today, YowCH sent the car in at 9:00am and got it back at 12:30pm (3.5hours only).
The coils were replaced, here is the leaking coils taken out.
Tomika also changed to a new cabin filter, and topped-up the aircon gas and compressor oil. All for $430 before GST. Aircon is now as good as before. Tomika is quite known to be reasonable and honest, and they are official suppliers of OEM Denso parts.
While at Alexandra village, YowCH bought some replacement engine filters ($9.50 each) and aircon filters ($13.00 each).
