Is my old furnace dangerous?

Age alone isn't the issue — cracked heat exchangers are. They can leak carbon monoxide into the supply air, which is why annual inspection matters and why every home with gas heat needs working CO detectors.

Can a heat pump handle winter here?

Cold-climate heat pumps handle much of the season, but Fort Collins's deep cold stretches push them to their limits — most setups pair the heat pump with a furnace or electric backup for the coldest nights. A pro can tell you whether your home is a good candidate.

How often should my furnace be serviced in Fort Collins?

Every fall, without exception. Fort Collins's long, cold heating season is brutal on furnaces, and a tune-up catches failing ignitors, dirty flame sensors, and cracked heat exchangers before the coldest nights — when a breakdown becomes a frozen-pipe emergency.

Homes here, and the HVAC problems they get

Local housing notes

New mountain-modern builds with cold-climate heat pumps and high-efficiency furnaces.
Basement-heavy housing where furnaces live below grade and duct runs stay short.
Historic homes with retrofitted forced-air systems threaded through plaster and tight framing.

Common local HVAC issues

Dry winter air: heated mountain air drops indoor humidity dramatically — static, dry skin, and shrinking woodwork.
Attic duct heat loss: long duct runs through cold attics bleed heat before it reaches rooms.
Summer cooling shortfalls: older homes sized for milder summers now face hotter heat waves with undersized AC.
Heat-pump defrost struggles: extended sub-freezing stretches push heat pumps to their limits, and backup heat does the heavy lifting.
Old Town's historic storefront apartments and carriage houses hide ancient ductwork and uninsulated party walls that bleed heat to the alley.
CSU student housing turns over every August, and landlords who schedule filter changes and coil cleanings between leases see fewer emergency calls.
Horsetooth-area homes on windy ridges face brutal infiltration; blower-door testing pinpoints the leaks that caulk and foam can actually fix.
Cache la Poudre canyon cold-air drainage can freeze condensate drains on high-efficiency furnaces overnight, so insulated and heat-taped lines matter.
Fort Collins' aggressive energy codes push new builds toward heat pumps and tight envelopes; commissioning reports verify the systems perform as designed.

Most Colorado jurisdictions require a mechanical permit for furnace replacements, and gas-line work adds its own requirements. The installing contractor typically pulls the permits — confirm before work begins.
