Services in Denver

Everything your Denver home needs

One in six Denver homes (16.9%) was built in 1939 or earlier. Denver’s pre-1940 housing means boilers, gravity furnaces, chimney-vented water heaters and houses with no ductwork at all show up far more often than in the suburbs.

$150 – $900+

AC Repair

When the AC quits in Denver, the July average high is 89.9°F and the upstairs bedrooms go first. We diagnose the actual failure, quote a flat price before any work, and carry the common parts on the truck.

$150 – $1,200+

Furnace Repair

Denver plans around a 5.8°F winter design temperature. When the furnace stops, we find the failed part, give you a flat price before we start, and fix most problems on the first visit.

$3,800 – $10,000 installed

AC Installation

A new AC in Denver should be sized to your house at 5,280 feet, not copied from the old unit’s label. We run a load calculation, quote flat-rate, pull the Denver Community Planning & Development permit and handle the paperwork.

$3,500 – $8,500 installed

Furnace Replacement

Replacing a furnace in Denver means sizing for a 5.8°F winter design temperature, venting correctly at 5,280 feet, and pulling the right permit. We quote flat-rate, and the price we quote is the price you pay.

$6,000 – $15,000 before rebates

Heat Pump Installation

Cold-climate heat pumps work in Denver, including on a 5.8°F winter design temperature nights, when they are sized and set up correctly. We design the system, pair it with backup heat where it makes sense, and line up every rebate your address qualifies for.

$150 – $1,200+

Heat Pump Repair

Heat pumps in Denver 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.

$900 – $2,800 installed (replacement)

Water Heater Repair & Replacement

No hot water in Denver? We repair and replace tank and tankless water heaters, gas and electric, and handle the Denver Community Planning & Development permit when a replacement needs one.

Quoted per zone

Ductless Mini-Split Installation

Ductless mini-splits heat and cool rooms the central system never reached, such as additions, basements, garages and older Denver homes built without ductwork. We design by zone and install cold-climate models rated for Colorado winters.

Furnace tune-up $100 – $149; AC tune-up $100 – $129

HVAC Maintenance & Tune-Ups

Two visits a year keep a Denver system ready for a 89.9°F July and a 5.8°F winter design temperature. Our tune-ups include combustion and CO testing, electrical checks, coil cleaning and an honest report on what is actually wearing out.

Flat-rate, quoted before work

Emergency HVAC Repair

No heat on a 18.7°F night or no AC on a 89.9°F afternoon in Denver? Call (303) 627-3395. We dispatch from Centennial and give you a flat price on the phone before anyone starts work.

HVAC in Denver: common questions

How much does HVAC service cost in Denver?

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 Denver?

Repairs generally do not. Replacing or installing a furnace, AC, heat pump or water heater does. Permits for Denver addresses go through Denver Community Planning & Development. Most residential equipment swaps are Quick Permits through Denver e-permits, with a separate Boiler and AC quick-permit type; contractors need a Denver license backed by a supervisor certificate. We pull the permit and schedule the inspection.

What HVAC rebates are available in Denver 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. Denver’s residential heat pump rebate (Climate Action Rebate) is fully subscribed and not available to single-family homes in 2026. Income-qualified homeowners in the Valverde neighborhood can get whole-home electrification through Xcel’s 2026 neighborhood retrofit pilot. Xcel’s gas furnace rebates ended Jan. 1, 2026, and the federal 25C credit does not apply to 2026 installs.

Who provides gas and electricity in Denver?

Electric: Xcel Energy citywide. Gas: Xcel Energy. That matters because rebates, operating costs and who you call about a gas leak all depend on the utility.
