Serving Boulder County since 2009
Comfort that holds through a Front Range winter
Furnace and air conditioning repair, replacement and maintenance — from technicians who explain what they found before they fix it.
No heat or no cooling?
We hold same-day slots for emergencies through the heating season. Call and you will speak to someone in Boulder, not an answering service.
The company you call when the last one guessed
Ridgeline works on the homes along the Front Range as they actually are — 1950s bungalows with one return, split-levels that cook upstairs every August, additions nobody ducted properly.
We size equipment against the house, not the square footage on the listing, and we would rather talk you out of a system you do not need than sell it twice.
What we work on
Heating
Furnaces, boilers and heat pumps — repair, replacement and annual service.
Cooling
Air conditioning and heat-pump cooling, sized against your house.
Air quality
Filtration, humidification and ventilation for wildfire season and dry winters.
Maintenance plans
Two visits a year, priority scheduling and no overtime charges.
Why homeowners choose us
The part that is hard to advertise
Same-day emergency slots
Held open through the heating season, because a furnace that quits in January is not a next-week problem.

“Our furnace quit on the coldest night of the year and Ridgeline had someone at the house before eight the next morning. He showed me the cracked igniter before replacing it, which no one has ever bothered to do.”
“They sized the new air conditioner against the actual house rather than the square footage on the listing, and talked me down from the bigger unit I thought I wanted. The upstairs is finally usable in August.”
“Third winter on the maintenance plan. They come when they say they will, and the one time something did go wrong it was covered without an argument.”
