- ✕ Visible water dripping from the indoor unit onto ceilings, walls, or furniture
- ✕ Musty or smelly smells every time the aircon is switched on
- ✕ Climbing SP Group electricity bills because units are dirty or undersized
- ✕ Fear of hidden charges from contractors who bait-and-switch

What Singapore Homeowners Say
Real reviews from Jurong West, Clementi, Bukit Batok, and beyond.
"Our 9-year-old Daikin was blowing warm air and dripping water. Coolbest diagnosed a blocked drain and low gas, fixed both the same afternoon. Still running strong six months later."
"Mr Chong quoted the chemical overhaul on the phone, stuck to the price, and actually laid down dust sheets. My Mitsubishi Starmex smells brand new again."
"Needed a multi-split installed for a new BTO handover. Team handled the HDB approvals and brackets, vacuumed the pipes properly, and tidied up. Fair price, zero drama."
"Gas top-up for an R32 system — booked, quoted, done in 40 minutes. Cool again by dinner. Will use them for routine servicing from now on."
