Denver, CO
Air Conditioning in Denver: what's different
Air Conditioning work in Denver follows the local climate. Cooling seasons are shorter in cold climates, but summer heat waves still bring urgent AC calls, often for systems that sat unused all winter. Spring start-up checks catch failed capacitors, low refrigerant and blocked drains.
A common Denver pattern: dry air. Humidifiers are popular in winter. Another: hail. Hail damages outdoor units.
The air conditioning services Denver homeowners ask for most are AC Replacement & Installation, evaporative (Swamp) Cooler Service. Correctly sized new systems, SEER2 ratings and refrigerant changes.
Denver's Community Planning and Development department issues mechanical permits and requires licensed contractors. Schedule furnace service in early fall and AC service in spring. Hail season peaks from May through August, so check outdoor units after storms.
