Local know-how
What we see in Centennial homes
Many neighborhoods in Centennial were built from the late 1970s through the 1990s. Most of those homes are on their second furnace and air conditioner by now, and some of the second ones are due again. An air conditioner installed before about 2010 may still run on R-22, a refrigerant that is no longer produced, which makes any leak an expensive repair.
Two-story houses with finished basements are common here, and one system often has to serve three very different floors. Zoning, a second thermostat or a variable-speed system can help, and sometimes balancing the existing dampers is enough.
Dry winter air is another common complaint. A whole-house humidifier on the furnace adds moisture as air moves through, and a properly set one eases static shocks and dry skin without fogging the windows.
We stock common furnace and AC parts for equipment of this age on our trucks, so many repairs finish on the first visit.

4 out of 5 stars
They replaced our 1990s furnace with a high-efficiency one and did a load calculation instead of just matching the old size. The permit inspection took a few days to schedule, but the install crew was tidy and explained the new thermostat.

Hail flattened a lot of the fins on our outdoor unit and the AC was struggling. They combed out what they could, cleaned the coil and told us honestly the unit still had a few good years in it.

Booked a fall tune-up. The tech found a cracked condensate line on the furnace and a filter slot that let air go around the filter. Fixed both. They had to move my appointment once, but they called a day ahead.
