Total HVAC Houston has provided heating and cooling services in the greater Houston area for over two decades, carrying a 5.0-star rating from 18 reviews and operating a 24/7 service model that covers both residential and commercial HVAC needs. Reachable at (281) 749-1195 and accessible via their site at greaterhoustonhvac.com, the company offers free estimates and dispatches technicians around the clock.

The service menu is comprehensive: 24-hour AC services, AC installation, AC repair, residential AC service, furnace repair, heat pump services, heating replacement, heating installation, air filtration systems, air purifiers, germicidal UV light systems, and commercial AC and heating services. The germicidal UV light system installation is a specialty offering—these systems use ultraviolet light to neutralize airborne bacteria, viruses, and mold spores within the HVAC system before they circulate through the home. For Houston homeowners with allergy or respiratory concerns, UV germicidal systems represent a meaningful air quality upgrade.

Total HVAC emphasizes three operational commitments on their site: decades of experience, an unbeatable warranty program that includes both extended manufacturer and labor warranties, and 24/7 availability. The warranty commitment is worth noting—many contractors offer manufacturer warranties without adding their own labor warranty, and Total HVAC's inclusion of both gives customers protection against both equipment defects and installation issues.

Technicians Sebastian, Adrian, Jose, Chase, and Julia's family describe a company that communicates proactively—calling before arrival, confirming appointments, and following up on ordered parts. One review describes a technician identifying a safety issue in the heating system and scheduling a return to resolve it, demonstrating the kind of proactive care that prevents larger problems down the line. A long-term reviewer describes having their HVAC system installed by Total HVAC seven years ago and never regretting the choice—a loyalty statement earned through sustained reliability rather than a single interaction.
