Services in Thornton

Everything your Thornton home needs

Most Thornton homes were built from the 1990s on, with older 1950s–70s stock in south Thornton. In Thornton the electric provider can change from one street to the next (Xcel or United Power), and that decides which heat pump rebate a homeowner can use.

$150 – $900+

AC Repair

When the AC quits in Thornton, the July average high is 91.1°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

Thornton plans around a 1°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 Thornton should be sized to your house at 5,210 feet, not copied from the old unit’s label. We run a load calculation, quote flat-rate, pull the City of Thornton Building Inspection Division permit and handle the paperwork.

$3,500 – $8,500 installed

Furnace Replacement

Replacing a furnace in Thornton means sizing for a 1°F winter design temperature, venting correctly at 5,210 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 Thornton, including on a 1°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 Thornton 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 Thornton? We repair and replace tank and tankless water heaters, gas and electric, and handle the City of Thornton Building Inspection Division 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 bonus rooms over the garage. 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 Thornton system ready for a 91.1°F July and a 1°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 19°F night or no AC on a 91.1°F afternoon in Thornton? Call (303) 627-3395. We dispatch from Centennial and give you a flat price on the phone before anyone starts work.

How much does HVAC service cost in Thornton?

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 Thornton?

Repairs generally do not. Replacing or installing a furnace, AC, heat pump or water heater does. Permits for Thornton addresses go through City of Thornton Building Inspection Division. Every contractor needs a City of Thornton Class D Mechanical license before a permit is issued, and applications go through the CityView portal. We pull the permit and schedule the inspection.

For heat pumps: either Xcel’s or United Power’s heat pump rebate, 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. Xcel’s gas furnace rebates ended Jan. 1, 2026, and the federal 25C credit does not apply to 2026 installs.
