What do recent reviews say?
THL HQ Aircon wins consistent praise for on-time service, tidy work, and staff courtesy across dozens of jobs over five-plus years. Technicians like Yoon, Raj, and Soh are named for technical skill and professionalism. Pricing is transparent, and the admin team responds quickly via WhatsApp. However, a small but vocal minority report unresolved cooling after servicing, recurring refrigerant leaks, and installation damage they say the company dismissed, raising concerns about consistency.

AR Contractor Pte Ltd (Best Painting & Aircon Service Provider in Singapore)
5.0(599)✓ Google-verified
Five-star dominance across nearly 600 reviews shows customers consistently get fast, polite technicians who arrive on schedule and clean thoroughly. Reviewers name staff members (Sohel, Ontor, Sojib, Sagor, Hossain Ali) and praise their professionalism; the company responds quickly to calls and arranges visits without fuss. Chemical wash and general aircon service draw particular praise. One or two four-star ratings appeared, though these still called the work decent and good without elaborating on shortcomings. AR Contractor covers HDB flats, condos, and landed properties across Singapore. Their website lists 10+ years in business with BCA training and bizSAFE Level 3 certification. They bundle painting, electrical, and flooring alongside aircon work, but reviews focus almost entirely on aircon servicing, installation, and chemical cleaning. No pricing is mentioned in reviews, and no complaints about cost, delays, or unfinished jobs surface.
