Professional Heating Services in Boulder, CO
Three different systems heat Boulder homes — gas furnaces, heat pumps, and boilers — and all three have to survive the same punishing conditions: altitude that derates equipment, Chinook winds that swing 40 degrees in an afternoon, and a heating season that runs from fall deep into spring. When your heat fails or it's time to replace it, the right move depends on which system you have and what fits your home going forward. Boulder HVAC Pros repairs all three, installs what's next, and tells you honestly which path makes sense. For heating service in Boulder, call (720) 764-0399.
Furnaces • Heat pumps • Boilers — all sized for altitude
Why We Are The Top Heating Services Company In Boulder
We handle every way Boulder heats. Most heating results are plumbing-and-electrical generalists; we’re a heating-first specialist that repairs and installs gas furnaces, heat pumps, and boilers — and routes you to the right one instead of the one we happen to sell.
We tune for 5,319 feet (USGS). At altitude, heating equipment loses capacity to thin air and Chinook swings make systems cycle harder; we account for that in every diagnosis and installation, not with sea-level settings.
Reliable Heating Repair Services & Maintenance
Gas Furnaces. A gas furnace burns natural gas and distributes heat through ductwork — still the most common system in Boulder, and often the most cost-effective for homes with existing gas service, provided it’s correctly derated for altitude. For a furnace that’s short-cycling or failing, see our furnace repair page; if you’re weighing a new one, our furnace installation and replacement page walks through sizing and the gas-versus-heat-pump math.
Heat Pumps. A heat pump both heats and cools by moving heat rather than burning fuel, and cold-climate models keep heating in Boulder’s sub-zero snaps. It’s the system that unlocks the largest Xcel Energy and Colorado rebates. For a new system and the full rebate stack, see our heat pump installation page; for icing, a spiking electric bill, or a unit that won’t switch modes, see our heat pump repair page.
Boilers and Radiant Heat. A boiler heats water and circulates it through radiators or in-floor tubing — a hydronic system distinct from forced-air. It matters in Boulder because the area’s older housing stock includes many homes on boiler and radiant systems that most generalist “heater repair” pages ignore entirely. A well-maintained boiler delivers even, quiet heat and can outlast a forced-air furnace; if your radiators are uneven, the boiler is short-cycling, or you hear knocking in the pipes, it’s worth a specialist’s diagnostic.

Our Local Heating Service Process In Boulder
We've refined our heating service process so every Boulder homeowner receives the same smooth, efficient, and customer-friendly experience. Here's how every heating service call across Boulder County is handled, whether it's furnace repair, heating maintenance, or new heating installation.
Why It Matters
In Boulder, a Heating Failure Isn't an Inconvenience — It's a Risk
Boulder winters routinely drop below zero, and a heating system failure during a cold snap is far more than uncomfortable. Frozen pipes burst within hours of indoor temperatures dropping below 32 degrees. Indoor air quality plummets when furnaces aren’t venting properly. Emergency repair costs spike when every HVAC company in town is booked solid. Reliable heating services aren’t optional in Colorado, they’re protective.
What a Heating Failure Actually Costs
A heating system that fails in a Boulder cold snap can go from a simple repair to frozen pipes and water damage within hours.
Prevents Frozen Pipes
Restoring heat quickly keeps indoor temperatures above the point where plumbing freezes and bursts.
Reduces Carbon Monoxide Risk
On gas systems, proper repair includes a heat-exchanger and venting check; a cracked exchanger is a fault that means the system shouldn’t run until it’s addressed.
Extends System Lifespan
Timely repair and altitude-correct service help a furnace, heat pump, or boiler reach the top of its service life.
Lowers Energy Bills
A system fixed and tuned for altitude runs efficiently instead of wasting fuel or leaning on backup heat.
Protects Warranty Coverage
Documented, correct repair helps keep manufacturer coverage intact.

What Colorado's 2026 Energy Code Means for Your Heating
Boulder homeowners keep asking about “the new Colorado furnace law,” so here’s the accurate version: it is not a ban on gas furnaces. Colorado’s Model Low Energy and Carbon Code took effect as the state’s minimum on July 1, 2026, raising energy-efficiency requirements for building systems and adding electric-ready provisions, and Boulder County has incorporated Electric Ready and Solar Ready requirements into its code. You can still install a qualifying gas furnace — the code simply sets a higher bar for what qualifies and adds a compliance dimension.
What actually changes is that a heating replacement now carries a compliance dimension it didn’t before — the equipment has to meet the code’s efficiency thresholds, and electric-ready provisions may apply depending on the project. That’s exactly the kind of detail a knowledgeable Boulder installer handles as a matter of course and pulls the permit for, so it passes inspection the first time.
