About us
25+ years of heating, cooling and water heater work
Hot & Cold Mechanical is a licensed and insured HVAC and water heater company based in Boulder County and Surroundings.
Who we are
We handle heating and cooling — furnaces, air conditioners, swamp coolers, boilers and water heaters (tank and tankless) — and we do all three kinds of work on them: service, repair and installation.
25+ years in the trade means most of what shows up on a service call is something we have seen before. That experience is the difference between guessing at a problem and knowing where to look first.
We are licensed and insured for the work we do in your home. And when you call 303-772-1296, you get a real person on the phone who can talk through what your system is doing — not a call center taking a message.
How we work
- Straight answers. If a repair makes more sense than a replacement, we’ll say so, and the other way around.
- One company for the whole house. The furnace, the AC, the swamp cooler and the water heater — no juggling three different contractors.
- Local. We’re based right here in Boulder County and Surroundings.
- Trained & up to date. Our technicians keep up with ongoing training and certification, so we stay current on the latest HVAC technology and products — heat pumps included.
