Reviewers consistently report punctual visits, thorough work, and staff who explain what they are doing. Technicians keep job sites clean, offer honest advice without pressure, and handle both routine maintenance and problem diagnosis (like odour removal). Named technicians Sen, Lo, Xi, Ah Lun, and Vic appear across multiple positive reviews, suggesting continuity.
Long-term customers use the service repeatedly. The business does not hard-sell upgrades. Common feedback emphasises speed, efficiency, and straightforward pricing without hidden charges.
Five-star reviews praise professional installation, neat work, and quick service. However, recent contract customers report lost contact, delayed responses, and pressure to upsell expensive services. One customer was misdiagnosed on a gas leak and left without resolution. Overall mixed record.
Most reviewers praise Mastercool's speed, professionalism, and fair prices, with several naming technicians Ah Teck and Tay for their knowledge and care. One recent review alleges deliberate gas venting during routine checks to justify unnecessary repairs, describing the technician appearing to release gas for 2 minutes after noting pressure, then claiming a leak and resulting in low pressure days later. While the majority rate them highly, the specificity of this accusation warrants direct observation during pressure checks.
Not enough recent reviews yet to synthesise a reliable sentiment read for this business.
