Heat pump or furnace? That is the first thing that matters when the heat quits in Boulder, CO, because the two fail in completely different ways. Heat pumps tend to freeze up when defrost stops working, get stuck in cooling when a reversing valve fails, or quietly lean on the electric backup strips, at several times the normal operating cost, when the outdoor unit dies. Gas furnaces usually come down to the flame sensor: once oxide coats it, the burners light but the flame cannot be proven, so the board cuts the gas and locks out after three tries. After that, we most often find cracked hot surface igniters, stuck pressure switches, clogged condensate traps on high-efficiency models, and blower motors at the end of their life.
The repair homeowners call us about most is Furnace Repair. Start there if your system isn't running right.
When to Call for Heating Repair in Boulder
The sooner you notice these red flags, the easier and cheaper the fix. Watch for these telltale signs:
- No warm air at the registers even with the heat turned up
- A furnace that tries to light, clicks, and then quits
- A heat pump's outdoor unit encased in frost or ice
- Cold rooms in one part of the house while others are comfortable
- A rotten-egg, burning, or musty smell once the heat kicks on
- A loud boom when the burners light, which points to delayed ignition
- Frequent on-off cycles that never bring rooms up to temperature
- Energy costs climbing even though the house feels colder
