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 Castle Pines?
Repairs generally do not. Replacing or installing a furnace, AC, heat pump or water heater does. Permits for Castle Pines addresses go through City of Castle Pines Building Department. Contractors need a City of Castle Pines Class G (Mechanical/HVAC) license before working in the city; no permits are issued to unlicensed contractors. We pull the permit and schedule the inspection.
What HVAC rebates are available in Castle Pines in 2026?
For heat pumps: either Xcel’s heat pump rebate or CORE’s thermostat credits, depending on which utility serves the address; 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. Black Hills gas customers get $260–$375 on a new 90%+ furnace. Xcel’s gas furnace rebates ended Jan. 1, 2026, and the federal 25C credit does not apply to 2026 installs.
Is it safe to run my Castle Pines furnace if it keeps short-cycling?
Short-cycling usually means a dirty flame sensor, a clogged filter or an overheating heat exchanger tripping the limit switch. The first two are cheap fixes; the third can be a carbon monoxide risk. If it cycles in under five minutes repeatedly, shut it off and call us. We test combustion and CO on every furnace repair call.
Who provides gas and electricity in Castle Pines?
Electric: CORE Electric for most addresses; Xcel in Hidden Pointe. Gas: Xcel Energy or Black Hills Energy depending on address. That matters because rebates, operating costs and who you call about a gas leak all depend on the utility.
