All Air Masters has earned a near-perfect 4.9-star average from 370 customer reviews in Upland, California. This family-run contractor handles installations, maintenance, and repairs across the Pomona Valley, with clients routinely noting Frank, Frankie, and their crew as among the most thorough and hardworking technicians they have ever hired. Whether the project involves a brand-new HVAC system or emergency heating repair, homeowners in Claremont, Montclair, and surrounding communities trust this team for straightforward guidance and reliable craftsmanship.

Reviewers repeatedly praise specific technicians by name rather than generic customer service scripts. Frankie Cruz arrived within 24 hours of a maintenance request, diagnosing the issue and replacing parts faster than expected while explaining costs clearly. During a full HVAC replacement, technician Fabian led a crew that customers called simply awesome for their coordination and care. For a complex attic duct installation involving a new Slimline AC unit, Rafael performed additional tasks without being asked, demonstrating genuine investment in the final result.

Homeowners planning upgrades can learn from real All Air Masters projects. A Claremont resident described a complete transformation when the crew constructed a new platform for the furnace, installed custom ducting, and added air vents and returns. Another customer shared that Frank Cruz identified her central heating problem quickly, answered every question patiently, and provided honest repair options instead of pushing unnecessary work.
