Furnace and heating repair
No heat at 9pm is a Front Range emergency. Igniters, inducers, and heat exchangers — repaired in place whenever it's safe. Denver sits at 5,280 feet, and a gas furnace up here has to be set up for thinner air following the manufacturer's high-altitude instructions, so we check the setup, not just whether it lights. Before you call, run the five checks for a furnace that won't heat; for on-off-on-off, see short cycling.
AC repair
Warm air, iced coils, dead capacitors. We diagnose the outdoor unit and get cooling back when Denver heat hits.
Tune-ups
Fall furnace tune-ups: heating inspection, filter check, safety test, written findings. Tune-ups are quoted per visit. The National Weather Service puts Denver's average first freeze on October 7 and first measurable snow on October 18 — find the weak part before the first cold night. What a tune-up covers.
Why Denver winters find the weak part
Cold arrives fast: on December 21–22, 2022, an arctic front took Denver International Airport from 51°F to −24°F. Dry winter air is one reason we install whole-home humidifiers.
How a visit works
Diagnose before we sell: a plain-language finding, and you approve the repair before parts come off the truck. Workmanship warranty on every repair.
