Heat Pump Installation in Louisville

Old Town Louisville's homes date from the coal-mining era, 1877 through the 1950s. Small rooms, plaster walls and later additions make new ductwork hard to run. Ductless heads or a slim-ducted unit for a few rooms are often the cleaner way to add heat pump heating and cooling, with the existing heat kept as backup. See our ductless guide for older homes.

Louisville's population tripled between 1980 and 2000, and the homes from that period, including surviving houses in Coal Creek Ranch, usually have a basement furnace and conventional ducts. When the AC fails, a heat pump on top of the existing furnace (dual fuel) is typically the best value.

Boulder County's heating design temperature is 0°F, colder than Denver's. We size from a room-by-room Manual J at that temperature and select equipment by its published 5°F capacity, corrected for the roughly 5,400-foot elevation. The same downslope winds that drove the Marshall Fire, with gusts up to 112 mph, mean outdoor units need secure mounting and placement out of drift zones.

A heat pump runs its blower more hours than a furnace, which makes it a good time to upgrade filtration. During wildfire smoke events, a high-MERV filter in a properly sized filter rack helps, provided the ducts can handle the added resistance. We check static pressure before recommending one.

Xcel Energy supplies gas and electricity in Louisville, so Xcel heat pump rebates apply. Installers report Xcel cut them on October 1, 2026, so confirm current amounts with Xcel. Louisville is a DRCOG member, so existing homes can get Power Ahead's $1,500 with contractor pre-approval. The Colorado heat pump tax credit is $1,000 in 2026, with at least $333 off your invoice. Boulder County's EnergySmart rebates are income-qualified only (at or below 100% AMI) since January 2026. The federal 25C credit has ended.

At current prices, a 95% furnace usually costs less to run than a heat pump in cold weather. An all-electric home that drops gas service saves the fixed monthly gas charge, which helps. See heat pump vs. furnace in Colorado.

The city's Building Safety division has a specific Furnace/AC/Water Heater/Heat Pump MEP permit, and every job requires a final inspection. We file the permit, coordinate electrical permitting for new circuits or a panel upgrade, and meet the inspector. Estimates are free and itemized.

Every estimate includes a written load calculation, the AHRI-matched equipment and its published 5°F capacity, the planned backup heat, and any duct, filtration or electrical work. That makes it straightforward to compare our proposal with others. Financing is available.
