Before you call — a few things customers ask.

Quick answers to the questions we hear most.

Do you really answer at 2 a.m.?

Yes. Our 24/7 emergency line is for real emergencies — no heat, no cooling, leaks, or anything dangerous. A tech will be in touch quickly. For routine service or quotes, calling during the day will be the fastest path to a scheduled visit.

Are estimates really free?

Yes — free estimates on new installations (furnace, AC, heat pump, water heater, etc.). We'll come out, walk the home or building, and put a written quote in your inbox. No pressure, no upselling.

Do you service my brand of furnace or AC?

We service all brands. For new installs we partner with industry-leading manufacturers including Amana, but we're brand-agnostic on repairs and maintenance.

Are you licensed and insured?

Fully licensed and insured. Our Colorado contractor license number is #125538500CL. Locally owned and operated — not a franchise.

Do you handle commercial HVAC too?

Yes. Light commercial HVAC is a core part of what we do — design, installation, retrofit, maintenance, and repair. Call us to talk through your building's needs.
