Claim This BusinessCoolmasters Air Conditioning and Heating has kept residents comfortable across Manor and Austin since 1997, building a reputation on 70 customer reviews that average 4.9 stars. This family-owned operation holds licenses, is bonded and insured, and operates Monday through Friday from 8 AM to 5 PM. The company serves both residential neighborhoods and commercial properties throughout the Austin metro, including establishments along South Congress Avenue and Downtown.
What separates Coolmasters from other HVAC contractors is their round-the-clock availability for emergencies paired with a 100% satisfaction guarantee. They handle commercial refrigeration systems including walk-in coolers and ice machines, a specialty many residential-focused contractors do not offer. Same-day service is available upon request, and their team installs and services all major brands.
Customer stories from reviews reveal the people behind the company name. When rjcuriel01 reached out on a Saturday evening, Madisson answered promptly and owner Mario made a house call to ensure everything was handled properly. Kaylene Thompson mentions Greg as the technician who took time to explain repair options and diagnosed issues accurately. These named accounts illustrate why reviewers recommend Coolmasters for honest, detailed service.
Eight reviews show strong satisfaction, with five-star ratings praising same-day response, owner involvement, and technicians named Greg, Madisson, and Dalton. One two-star review cited a filter specification issue that was partially resolved. All positive reviews highlight honest communication and diagnostic skill.
