Heat Pump Installation in Englewood
Englewood has a local rule that works in a heat pump buyer's favor. Since July 1, 2024, the city's Building Division has required a Manual J load calculation and a Manual D duct design for every HVAC replacement or addition. Since most of Englewood was built by 1960, that duct design often decides whether a ducted heat pump will work or whether ductless is the better route.
Why the Manual J and D rule matters for heat pumps
A gas furnace can push very hot air through small ducts and still heat a room. A heat pump delivers cooler supply air and needs more airflow to deliver the same heat. In a 1950s house with ducts designed for a small furnace, that difference shows up as noisy registers, high static pressure and rooms that never warm up.
Englewood's requirement means every bid should start with the numbers: heat loss room by room at the Arapahoe County design temperature of about 4°F, and a duct plan that can carry the airflow. We prepare both for the permit, and we use them to choose equipment by its rated capacity at 5°F after an altitude correction for 5,350 feet. Our sizing guide explains what to look for in those reports.

Englewood Climate Note
Older homes (1940s-60s) common in Englewood often have undersized HVAC, no insulation, and original gravity systems that need full replacement.

Postwar homes and older streets
About 44% of Englewood's homes were built between 1940 and 1969, and another 11% before 1940. Northwest Englewood has houses from the 1910s, while Arapahoe Acres (1949–1957, on the National Register) is a mid-century modern neighborhood whose homes used radiant floor heat combined with forced air. In homes like these, ductless heads or a slim ducted unit for a few rooms often make more sense than replacing a whole duct system. The existing heat can stay as backup.
Where the Manual D shows the ducts can handle it, a ducted heat pump on top of the existing furnace (dual fuel) is usually the least disruptive upgrade, especially when the AC is the part that's failing.
The electrical side
Many 1940s and 1950s houses have 60- or 100-amp service. An outdoor unit needs a dedicated 240-volt circuit, and an all-electric design with backup strips can push a small panel past its limit. We check capacity during the estimate. If an upgrade is needed, HomeGuide's national range for 100 to 200 amps is $1,300–$1,600. A licensed electrician does that work under its own permit.
Rebates and running costs
Xcel Energy provides gas and electricity in Englewood, so its heat pump rebates apply. Installers report they were cut on October 1, 2026, so confirm current amounts with Xcel. The city is a DRCOG member, so Power Ahead Colorado's $1,500 rebate is available with contractor pre-approval. The Colorado heat pump tax credit is $1,000 in 2026, and at least $333 must be passed to you on the invoice. The city also maintains a home energy rebates page worth checking. There is no federal 25C credit for a 2026 install.
Be ready for an honest answer on operating cost. At current Colorado prices, a 95% gas furnace usually costs less to run than a heat pump in the coldest months. A heat pump saves most when it replaces an old 80% furnace, electric heat or an AC that has to be replaced anyway. See heat pump vs. furnace in Colorado.
Permit and inspection
We submit the mechanical permit to Englewood's Building Division with the Manual J and Manual D attached, coordinate electrical permitting and schedule the inspection. Your estimate is free and itemized, so you'll see the equipment, its 5°F capacity and any duct or electrical work before you decide.

Heat Pump Installation FAQs — Englewood
Does Englewood really require Manual J and Manual D?
Yes. Since July 1, 2024, the Building Division has required both for all HVAC replacements and additions.
Can I put a heat pump in an Arapahoe Acres home?
Often, yes. Ductless or small ducted units can add heating and cooling without disturbing the original design, and the existing heat can stay as backup.
Will my old ducts work with a heat pump?
The Manual D answers that. Some homes need only a larger return. Others are better served by ductless heads.
What incentives apply in Englewood?
Xcel rebates (confirm current amounts), Power Ahead's $1,500, the state credit's minimum $333 discount, and any city program listed on its rebate page.
