HVAC St. George

Twice a year is the standard for combined heating and cooling systems: a cooling tune-up in spring and a heating tune-up in fall. In St. George’s climate, the heating side matters most before the first cold snap, when equipment that sat idle all summer gets fired up again. Annual heating service is the minimum we recommend.

Yes — Thompson services, repairs and installs furnaces, heat pumps, boilers, air conditioners and indoor air quality equipment. Because we also run plumbing and electrical crews, most homes can be covered end to end without a second contractor.

Furnaces and heat pumps typically last 15 to 20 years with regular maintenance. Air conditioners often need replacement sooner here because they run hard through long summers, and dust is harder on equipment than in wetter climates — which makes filter changes and tune-ups more important, not less.

The right size depends on square footage, insulation, window area and ductwork — not just the climate. An oversized system short-cycles and wears out early; an undersized one runs constantly and still falls short on the coldest and hottest days. We size every installation with a proper load calculation rather than a rule of thumb.

The VIP Club is Thompson’s Home Service Membership: it includes seasonal tune-ups, priority service scheduling, waived dispatch fees on service calls and a 10% discount on all repairs, across plumbing, HVAC and electrical. It’s the most cost-effective way to keep both halves of your HVAC system serviced on schedule.
