Your furnace picked the coldest night of the year to quit. Of course it did — they always do. We've been on the other end of that panicked phone call enough times to know exactly what you're feeling. The good news: we carry the parts that fix 90% of furnace failures right on the truck, and we're headed your way.
Let's be real — a dead furnace in Boulder isn't a minor inconvenience. When it's 5 below and dropping, your pipes are at risk within hours. We treat every no-heat call like the emergency it actually is. Ignitors, flame sensors, blower motors, thermocouples — the parts that take out most furnaces are on every truck, every day.

| Heat Pump | Defrost cycle failure, refrigerant issues, reversing valve | Valve repair, charge adjustment for altitude |
| Boiler / Radiant | Circulator pump failure, zone valve issues, air locks | Pump replacement, system bleeding, valve repair |
| Electric Furnace | Heating element burnout, sequencer failure | Element and sequencer replacement |
Boulder County experiences 155 heating degree days per year on average, with sustained cold snaps where temperatures remain below 10°F for days. The Chinook winds add another variable — rapid temperature swings of 40°F or more in a few hours stress gas valves, thermocouples, and expansion joints in heating equipment.
Many Boulder homes built in the 1950s through 1970s — particularly in South Boulder, Martin Acres, and Table Mesa — still have original or second-generation furnaces that may not meet current safety standards. Our techs inspect heat exchangers for cracks that can allow carbon monoxide to enter living spaces, a critical safety concern with aging equipment.
Most furnace repairs in Boulder range from $150 to $500. Complex repairs involving heat exchangers or blower motors may cost $500 to $1,200. We provide upfront pricing before beginning work.
First, check your thermostat settings and make sure the fan is set to AUTO, not ON. Then check the air filter — a clogged filter can cause overheating and safety shutoff. If those are fine, call us for a diagnostic.
Signs of a cracked heat exchanger include a yellow or flickering burner flame, soot around the furnace, a strong odor when the furnace runs, or headaches and flu-like symptoms in your household. This is a safety emergency — call immediately.
Yes. We provide after-hours heating repair service in Boulder. When temperatures drop below freezing, a heating failure is an emergency. Call (720) 881-7130 any time.
