Technicians like Daniel, Taqif, Mustakim and Haziq draw consistent praise for skill and honest diagnosis, but the business side has stumbled: unclear pricing approval and a case of water damage from unauthorised roof drilling stand out in the review set.

• Technicians explain and educate customers
• Fast turnaround on jobs

★★★★☆4.2 (6 reviews)score 65/100

EPSIS covers a different niche on this list, industrial air-cooled and water-cooled chillers plus HVAC installation and design, with reviewers calling the technical work honest and competent. The review base is thin at just 6 reviews, including one older complaint about management communication, so treat this as a low-confidence but specialised option.

• Skilled, honest technical work
• HVAC installation and design capability

Watch out: Very few reviews (6) and one flagged communication issue with management, so confidence here is low.
