HVAC repair and installation in Denver, CO
Denver's mile-high altitude, dry air and hail make HVAC here a little different. Gas furnaces must be set up for elevation, air conditioners lose some capacity in thin air, and many older homes still cool with evaporative coolers.

Denver homes and their HVAC systems
Bungalows and Denver Squares in Park Hill, Washington Park and the Highlands date to the early 1900s and often have basement furnaces with ductwork never designed for AC. Central Park and other newer areas have modern split systems and heat pumps.
Local conditions that affect your system
Altitude
Gas appliances are derated at elevation, and cooling equipment moves less heat per cubic foot of air. Sizing should account for it.
Hail
Summer hail flattens condenser fins and can puncture coils. Hail guards and a post-storm check are common.
Dry air
Winter humidity indoors can drop below 20%. Whole-home humidifiers are popular, but need to be sized and maintained.
Seasons and peak demand in Denver
Denver can swing 40 degrees in a day. Summer afternoons reach the 90s, while winter cold fronts drop nights below zero, sometimes right after a sunny 60°F day. Furnace demand peaks during those first sharp cold snaps in October and November, and hail season in May through July is when condenser damage shows up.

Denver HVAC FAQ
Does altitude affect my furnace in Denver?
Yes. Gas furnaces are derated for elevation so they burn safely and efficiently, and the installer should set gas pressure and orifices for Denver's altitude.
Should I replace my swamp cooler with AC?
Evaporative coolers work well in dry weather and cost less to run, but struggle on humid monsoon days. Many Denver homeowners switch to central AC or a heat pump for consistent comfort.
