24/7 EMERGENCY HVAC SERVICE AVAILABLE — DENVER & METRO (555) 012-4400
What we do
Heating & Cooling Done Right
Every service starts with an honest diagnosis. We fix what’s broken, replace what needs replacing, and leave you with a system that actually runs efficiently.
Air Conditioning
Repair, recharge, and full system replacement. Most AC repairs completed same day. Systems installed same week with proper load calculations — no oversizing.
From $149 diagnostic
Heating & Furnace
Gas furnace, heat pump, and boiler service. Denver winters are no joke. We diagnose, repair, and when replacement makes more sense, we say so — and explain why.
From $129 diagnostic
Emergency Repair
Heat out at midnight. AC down on a 95-degree Saturday. We run 24/7 emergency calls with a 2-hour arrival guarantee. Flat $99 diagnostic — no surprise fees.
$99 flat diagnostic

Real Reviews. Real Jobs.
“Called at 11pm on a Sunday when our furnace died with temperatures dropping below zero. They had someone here by 1am and fixed it that night. Absolute lifesavers.”

“Used Summit for our AC install last spring. Fair price, clean crew, and they walked me through the financing options clearly. No pressure, just facts. Really appreciated that.”
