Local know-how
What we see in Golden homes
Sitting right against the foothills, Golden sees colder nights and stronger winds than much of the metro. Furnaces work hard here, and a side-wall vent pipe facing the wind can be blocked by drifting snow. If a high-efficiency furnace quits during a storm, check the pipes outside before anything else.
Older homes near downtown often have a patchwork of heating, from original ducts to baseboard heaters or space heaters in additions. Ductless mini-splits are a practical way to heat and cool rooms that the ducts never reached.
Wildfire smoke drifts along the foothills in some summers. A better filter, matched to what your system can handle, keeps more of it out of the house, and we can check your airflow and recommend one.
If you are unsure whether a problem is urgent, call anyway. We would rather talk it through than leave you without heat overnight.

5 out of 5 stars
We added a cold-climate heat pump and kept the gas furnace as backup. They explained when each one runs and set the switchover with us. The first winter has been quiet and comfortable.

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.
