What we see in Highlands Ranch homes
Master-planned, built in phases since 1981. The first Highlands Ranch homes went up in 1981, and the community was built out in stages over the following decades. The oldest neighborhoods are now more than 40 years old and are often on their second or third furnace. Newer areas are reaching the age where builder-installed igniters, capacitors, and blower motors start to fail.
Unincorporated, with a community association. Highlands Ranch isn't a city. It's unincorporated Douglas County, with the Highlands Ranch Metro District handling parks and roads and the Highlands Ranch Community Association (HRCA) running the covenants. A repair in place doesn't change anything outside the house, but if a project turns into moving or adding outdoor equipment, check HRCA's guidelines first.
Around 5,800 feet. Highlands Ranch sits roughly 500 feet higher than downtown Denver. Gas furnaces at this elevation have to be set up for thinner air per the manufacturer's high-altitude instructions, and the dry winter air makes a whole-home humidifier worth considering.

Common questions
Do I need HRCA approval for a furnace or AC repair?
We can't answer for HRCA. A repair in place doesn't change the outside of the house. If an outdoor unit is moving, changing size, or going somewhere new, check HRCA's guidelines before the work starts.
Our house was built in the 1980s. Is the furnace due for replacement?
Age alone doesn't decide it. We repair first. If replacement is the honest path, you'll get numbers and time to think.
My heat pump is blowing cool air on a cold morning. Is it broken?
Not necessarily — heat pumps run a defrost cycle, and their air is warm, not furnace-hot. See the heat pump FAQ for the safe checks, then request a visit if the house keeps losing ground.
