• ✓Multi-trade capability beyond aircon

Why it ranks second

• ✓Efficient same-day or next-day visits

Why it ranks tenth

With over 10,000 reviews and a 4.9 average, 338 Aircon has the largest review base on this list by a wide margin. Technicians like Sankar, Mamun, Shahin and Yusof are named for patient explanations and for tidying up after mold-heavy chemical washes, not just the standard filter clean.

Why it ranks #11

Luce SG runs on app and WhatsApp booking with same-day or next-day slots and staff assigned by name to each job. The review base of nearly 9,700 is huge, but almost all of it discusses housekeeping work rather than aircon specifically, so treat the aircon side as unproven by recent reviews.

Pros

• ✓Same-day and next-day availability
• ✓Payment collected only after job completion
• ✓Responsive app and WhatsApp support

Why it ranks #12

• ✓Deep chemical cleaning and gas refill service
• ✓Long customer retention, including an 8-year relationship
