Heat Pump Repair
Heat Pump Repair for Lone Tree homes
Heat pumps in Lone Tree run all year, heating in winter and cooling in summer, so they wear faster than a furnace or AC alone. We diagnose defrost, reversing valve, refrigerant and control faults and quote the fix before we start.
We are a family shop, not a franchise call center. The tech who shows up can explain what failed and why, and the quote does not change after you say yes.
See our main heat pump repair page for how we approach this work across the metro.
Heat Pump Repair in Lone Tree: what’s different here
Lone Tree publishes its own HVAC design values: a -3°F winter design temperature, 90°F summer dry bulb and 6,343 heating degree days. Unlike its CORE-served neighbors, the city is Xcel for both gas and electric.
Defrost season
From November to March, Lone Tree nights average around 14.9°F. Outdoor coils ice up and the defrost cycle has to clear them; a failed defrost sensor or board is the most common winter call we get on heat pumps.
Snow and ice
Units need to sit above the snow line with clear drainage, or meltwater refreezes into the fan and coil. We check the pad height and clearance on every call.
Year-round wear
A heat pump logs roughly twice the run hours of a single-season system. Capacitors, contactors and the outdoor fan motor get the hardest use.

Our published range is $150 – $1,200+. Every Hytek job is quoted flat-rate and approved before work begins, so the price you agree to is the price you pay. Replacements get free in-home estimates; see the full HVAC cost guide for the other services.
Do I need a permit for HVAC work in Lone Tree?
Repairs generally do not. Replacing or installing a furnace, AC, heat pump or water heater does. Permits for Lone Tree addresses go through City of Lone Tree Building Division. Permits are online-only through the city’s Accela portal. Lone Tree does not issue contractor licenses, but everyone on a permit must hold a Lone Tree business license. We pull the permit and schedule the inspection.
What HVAC rebates are available in Lone Tree in 2026?
For heat pumps: Xcel Energy’s 2026 heat pump rebates (the largest bonus goes to homes replacing gas heat); the $1,500 Power Ahead Colorado rebate (pre-approval required); Colorado’s $1,000 air-source heat pump credit, at least a third of which the installer must pass to you as a line-item discount. Xcel’s gas furnace rebates ended Jan. 1, 2026, and the federal 25C credit does not apply to 2026 installs.
Why is my heat pump blowing cold air in Lone Tree?
Usually one of three things: it is in a defrost cycle (normal, a few minutes), the reversing valve or its solenoid has failed, or it is low on refrigerant. If cold air lasts more than 10–15 minutes, or the backup heat is running constantly, call us.
Who provides gas and electricity in Lone Tree?
Electric: Xcel Energy. Gas: Xcel Energy. That matters because rebates, operating costs and who you call about a gas leak all depend on the utility.
