Customer Reviews

“Furnace died during the polar vortex in Naperville. Our maintenance plan with Summit meant we jumped the queue and had a tech at the door in 2 hours. Neighbors waited 3 days with other companies.”

“Old radiator system converted to forced-air in our Evanston Victorian. Summit designed a system that preserved our original woodwork while actually keeping every room warm. Exceptional craftsmanship.”

“New high-efficiency furnace in Schaumburg. The old one was 80% efficient, new one is 98%. Gas bills dropped by a third and the house heats evenly for the first time.”

“After a power surge during a tropical storm fried our compressor in Sugar Land, Summit had a temporary cooling unit set up the same evening and a new compressor installed two days later.”

“Clogged drain line was leaking water into our ceiling in Katy. They came out on a Saturday, fixed the drain, and found a failing capacitor during the same visit. Thorough.”

“The Woodlands humidity is brutal on HVAC. Summit's maintenance plan keeps our system running and our air quality clean. No surprise breakdowns in 3 years.”

“AC died on the hottest day of the year in Plano. Summit had a tech here in 90 minutes and the system was running again before bedtime. Lifesavers.”

“New furnace and AC combo installed in our Frisco home. Crew was here at 7 AM and done by 4 PM. Energy bills dropped 35% the first month.”

“Been on their maintenance plan for two years now. They catch things before they break. Worth every penny in McKinney heat.”

“Furnace quit on a -5°F night in Littleton. Summit's emergency tech arrived in under 2 hours, diagnosed a failed igniter, and had heat running again before midnight. Incredible response.”

“Installed a dual-fuel heat pump system in our Aurora home. Works as AC in summer and efficient heat pump in fall/spring, with the gas furnace kicking in only on the coldest days. Bills dropped significantly.”

“The altitude adjustment thing is real — our old company never tuned our furnace for Denver's elevation. Summit re-tuned it and the short-cycling stopped immediately.”

“Our Scottsdale AC failed at 112°F with a newborn in the house. Summit dispatched someone within an hour. I've never been more grateful for fast service.”

“Whole-home heat pump installation in Gilbert. They did the Manual J calculation and found our old system was 40% oversized. New system is quieter, cheaper to run, and actually keeps the house comfortable.”

“Tempe dust destroys AC coils. Summit's maintenance plan includes a coil cleaning every visit. System has run perfectly for 4 summers now.”

“Pollen had our outdoor unit so clogged it was barely cooling in Marietta. Summit cleaned it, found a low refrigerant issue from a slow leak, and fixed both. Night and day difference in cooling.”

“Heat pump install in Alpharetta — perfect for Atlanta's climate. Heats and cools efficiently without a gas line. Summit handled the whole project including the new thermostat setup.”

“Our Roswell home is 30 years old with original ductwork. Summit sealed the ducts, added returns to two rooms, and our AC actually reaches the back bedrooms now. Should have done this years ago.”
