AC Installation
AC Installation for Lone Tree homes
A new AC in Lone Tree should be sized to your house at 6,280 feet, not copied from the old unit’s label. We run a load calculation, quote flat-rate, pull the City of Lone Tree Building Division permit and handle the paperwork.
You get a flat price in writing before any work, and we will tell you plainly when a repair is not worth doing.
See our main ac installation page for how we approach this work across the metro.
AC Installation 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.
Sizing for Lone Tree
Design conditions here are a 87.9°F July average high at 6,280 feet. We size from a Manual J load calculation because an oversized unit short-cycles and leaves the house clammy, and an undersized one runs all afternoon.
Refrigerant change
New systems now ship with A2L refrigerants (R-454B or R-32). EPA’s May 2026 rule dropped the install deadline for leftover R-410A stock, so both are legal; we explain the trade-off on parts and service life before you choose.
Permit
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.

Rebates and programs for Lone Tree homeowners (2026)
Power Ahead Colorado: $1,500 off a new ENERGY STAR cold-climate heat pump (ducted or ductless) in an existing home. Needs pre-approval through a Power Ahead-badged contractor before work starts; stacks with utility and state incentives. Source
Colorado heat pump tax credit: $1,000 for air-source systems in 2026, claimed by a registered contractor who must pass at least a third to you as an invoice discount.
Our published range is $3,800 – $10,000 installed. 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.
Should I get a heat pump instead of a new AC in Lone Tree?
Often, yes. A heat pump costs more than a straight AC but also heats, and in Lone Tree it can qualify for Xcel Energy’s 2026 heat pump rebates (the largest bonus goes to homes replacing gas heat) and the $1,500 Power Ahead Colorado rebate (pre-approval required). A plain central AC has no current Xcel rebate. We quote both side by side.
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.
