Expert Heat Pump Repair in Boulder, CO
Your heat pump is running, the house still feels warm, and your Xcel Energy bill just jumped for no obvious reason. In Boulder that combination usually means one thing: the heat pump quietly stopped carrying the load and your expensive electric backup heat has been running full-time. Heat pumps fail differently here than furnaces do, and the symptoms — icing, a stuck reversing valve, runaway backup heat — are specific to a cold, high-altitude climate. Boulder HVAC Pros diagnoses the actual cause and tells you honestly whether it's broken or just doing its job. For heat pump repair in Boulder, call (720) 807-8673.

WHY WE ARE THE TOP HEAT PUMP REPAIR COMPANY IN BOULDER
We diagnose for how heat pumps fail here. Boulder’s deep cold, moisture, and same-day temperature swings produce specific faults — defrost problems, worn reversing valves, refrigerant issues that only show up in cold — and knowing the pattern is the difference between a real fix and a parts-swap that fails again in January.
Cold-climate certified. Our Mitsubishi Electric Diamond Contractor and Daikin Comfort Pro certifications mean we understand the defrost logic and low-temperature controls that generic shops guess at.
EPA 608 certified specialists. Our technicians handle refrigerant under EPA Section 608 certification — a real heating-and-cooling specialist, not a lead-gen listing.
A local specialist since 2005. A City of Boulder licensed, insured contractor, with a written estimate before any work and a workmanship guarantee behind it.
WHY BOULDER HOMEOWNERS TRUST US FOR HEAT PUMP REPAIR
A struggling heat pump is quietly expensive. When it stops carrying the load, your backup electric heat picks up the slack — and that shows up as a higher Xcel Energy bill every day it runs, long before the system looks obviously broken.
Boulder’s winter doesn’t let up. Heating season runs fall into spring, so a heat pump that’s icing or short on refrigerant is under constant demand; a minor fault caught early is a straightforward repair, while ignored it can escalate to a failed compressor.
Catch it before you decide. If the unit is near the end of its life, catching it now lets you weigh a rebate-eligible replacement calmly — see our heat pump installation page for the full Xcel and Colorado rebate stack.

Our Local Heat Pump Repair Process In Boulder

Why It Matters
A Heat Pump That Limps Along Costs You on Every Xcel Bill
Small heat pump issues reduce efficiency, increase energy bills, and often lead to expensive system damage if ignored too long.
Stops Year-Round Energy Waste
A heat pump fighting a fault runs longer and leans on backup heat; fixing it restores the efficiency you paid for.
Prevents Compressor Damage
Catching a refrigerant or airflow fault early protects the compressor, the most expensive part to replace.
Prevents Reversing Valve Failure
Boulder’s same-day heat-to-cool swings wear the reversing valve; catching it early avoids a bigger repair.
Reduces Auxiliary Heat Costs
Electric backup strips run at roughly two to three times the cost of the heat pump itself; fixing the fault stops them running full-time.
Protects Warranty Coverage
Proper, documented repair with correct refrigerant handling helps keep manufacturer coverage intact.

Is It Broken, or Is That Just How a Cold-Climate Heat Pump Runs?
Boulder added a wave of heat pumps during the electrification push, and many newer owners aren’t used to how they run. A cold-climate heat pump normally has longer cycles, delivers supply air that feels cooler than a furnace’s, and gives off visible steam during a defrost cycle — none of which is a fault. Before you pay for a repair, it’s worth knowing whether what you’re seeing is normal, and we’ll tell you honestly.
