What we do
Six services, prices upfront
Rates below are per wall-mounted unit. We confirm the price on WhatsApp before booking. Book three units in one visit for a discount.
Routine servicing
Filter, blower and coil cleaning, plus a cooling check. Do this every three to four months for units used daily.
RM 80/unit
Chemical wash
We strip and wash the indoor unit with coil-safe chemical. This clears blocked fins, mould and drip-tray sludge.
RM 160/unit
Chemical overhaul
A full dismantle with fan barrel removal and drain flushing. For units that leak water or blow weak, musty air.
RM 300/unit
Gas top-up
R32 and R410A top-ups, done only after a leak check confirms gas is the problem. We show you the pressure readings.

SurayaHomeowner, USJ 4 Another company quoted me a gas top-up. CoolFlow checked and found a blocked coil instead. They did a chemical wash, and the room has been cold since March.
MarcusCafe owner, SS15 Subang Jaya I manage six tenanted units. I just forward tenant complaints to their WhatsApp. Slot confirmed the same day, job done within the week, every time.
