Will they follow up if the issue isn't fixed on the first visit?

Yes. In one case, when a leak was not identified initially, the owner (Hao Jun) personally called back and sent the same technicians within two hours to resolve it at no extra cost.

Can I get a quote before booking?

Yes. Reviews mention quotes are given with clear expectations and steps outlined before appointment confirmation.

Do they charge for diagnostics if I don't proceed?

They may charge a leak-check fee, but it is waived if you proceed with servicing, as one customer experienced.

Kai Leong Air-conditioning & Engrg. Pte Ltd

Services: Aircon Repair, Aircon Installation, Aircon Servicing & Maintenance
Reviews: 47

What recent reviews say

Most customers praise Kai Leong for fast responses, honest pricing, and thorough diagnostic work that rival companies missed. Technicians are named, polite, and clean up spotlessly; many customers return year after year, some for over 20 years.

However, one recent five-star review noted installation quality fell short of expectations, though the business's service recovery on repairs is strong. Prices are fair for the expertise shown; staff proactively follow up after visits and explain maintenance needs without upselling.

Caredy Air-conditioning & Electrical Services

5.0(105)✓ Google-verified

Caredy consistently delivers on two fronts: speed and trust. Reviewers report same-day or next-day appointments, fast turnarounds once on site, and staff who actively steer clear of unnecessary work. They cover furniture with plastic, clean up thoroughly, and explain what they are doing step by step. Jin Teck (named in multiple reviews) and his team handle routine servicing, repair diagnostics, and emergency call-outs with equal care. One reviewer paid only for the actual fix after the diagnosis changed, another had Caredy make two trips to source the right part, a third saw a technician squeeze them in despite a full schedule. Honest quotation and no upselling are the consistent threads.
