What we do
Duct cleaning
Whole-home supply and return cleaning, register and grille wipe-down, and a system run-check when we're done. The job our service stickers are built for. Duct cleaning details
Heating & furnaces
No heat at 9pm is a Front Range emergency. Igniters, inducers, and heat exchangers — repaired in place whenever it's safe. Furnace repair · Furnace not heating FAQ
Tune-ups & filters
Seasonal visits so a cheap part doesn't take out the board: heating inspection, filter check, safety test, written findings. Fall furnace tune-up
Heat pumps
Cold-climate and dual-fuel systems that have to work in a Denver January, not just a brochure.
Air conditioning
Warm air, iced coils, dead capacitors. We diagnose the outdoor unit and get cooling back when Denver heat hits.
Emergency repair
System down and the house is uncomfortable? Pick "Emergency — come now" on the request form. Call for service · Emergency available.
You buy, we install
Mini-splits, UV lights, and whole-home humidifiers. Buy the unit on Amazon — we hang it, wire it, and stand behind it. Refrigerant, 240-volt, and water lines stay on us. We install
Stuck mid-install
Amazon box in the garage, indoor head on the wall, line set hanging? We finish installs homeowners start — no lecture. Tell us what you bought and where it stopped.
DIY supplies
Filters, carbon monoxide detectors, a thermostat, room purifiers, and other things you can do without a license. DIY shop
