Broomfield
Broomfield is its own city and county, and it is really two towns in one. The original core grew up as a bedroom community in the 1950s along the new Denver-Boulder Turnpike, starting with the Broomfield Heights neighborhood the city still calls the First Filing. The other Broomfield is Interlocken, Anthem, Broadlands, and the north side, almost all built since the 1990s. The median home dates from 2002.

Why Broomfield Homes Are Different
Two Broomfields, two sets of problems
More than half of Broomfield’s homes were built after 2000 and fewer than one in ten before 1980. The 1950s and 60s core and the 2000s north side fail in completely different places, and the utility line that splits the city in two decides which rebates apply.
Broomfield Heights and the 1950s core
Post-war ranches with a few inches of original attic insulation, uninsulated walls, and ductwork that has outlived two furnaces. Seal the attic and bring it to depth before anything else.
Anthem, Broadlands, Wildgrass, and McKay Landing
Post-2000 production two-stories: thin attics, open top plates, open rim joists, rooms over garages. Tight enough to look finished, leaky enough to show on the bill.
Two electric utilities
United Power serves the north side of the city and Xcel Energy the south, with Xcel gas throughout. Your electric bill decides which heat pump rebates you can use.
Radon in a Zone 1 county
Colorado’s health department puts all 64 counties, Broomfield included, in the EPA’s highest radon zone. You will not know without a test.
Diagnostics
What we commonly find in Broomfield homes
These are the patterns that show up repeatedly in this housing stock and climate. Your home gets tested, not assumed, but this is where we look first.
Original attics in the First Filing
1950s ranches in Broomfield Heights were insulated to a few inches at most, and what is there has compressed. Depth checks come back far short of current targets.
Rim joists in the 2000s two-stories
The band of framing where the floor meets the foundation, and where the garage meets the house, is routinely uninsulated in Anthem and Broadlands plans.
Wind-loaded west and north faces
Downslope wind loads the exposed faces of a house and sucks conditioned air out the far side; the leaks that matter are at the top plates and penetrations, not the windows.
Ducts in unconditioned attics
Both eras run ducts through attics that bake in summer and freeze in winter. Sealing and insulating them is a quiet, high-return fix.

Local Rebates
Rebates for Broomfield addresses
Broomfield’s rebate picture depends on which side of the city you live on. South-side Xcel Energy addresses can use Xcel’s audit rebate (as much as 60% back), its separate insulation, air sealing, and HVAC rebates, plus the $600 it adds to a heat pump that follows envelope work. North-side United Power addresses get the co-op’s 2026 heat pump rebates (ducted systems $500 or $1,000 by size, mini-splits $250 or $500) and no insulation rebate, so the envelope case there rests on the bills.
The city’s own rebates page mostly passes along Xcel offers, including the envelope-first heat pump bonus, plus a Switch Together group-buy program and Xcel’s Home Energy Squad visits. Power Ahead Colorado’s $1,500 metro heat pump rebate applies in Broomfield but only through contractors the program has verified, and PowerHouse is not on that list today, so we explain it rather than promise it.

Broomfield questions, answered
How do I know if I am Xcel or United Power?
Your electric bill. Roughly, the north side of Broomfield is United Power and the south is Xcel, with Xcel gas everywhere. We confirm it before quoting because the rebates differ.
My 1960 Broomfield Heights ranch is drafty. Where do I start?
With a blower door. In these ranches the attic, the rim joist, and sixty-year-old ducts are the usual culprits, and sealing them before adding insulation changes the house more than a new furnace.
Does the city pay rebates of its own?
Not cash rebates; its program page points to Xcel’s offers, a Switch Together group buy, and free Home Energy Squad visits. We stack the Xcel pieces on our work and file them.
Is my Anthem house too new to need this?
Rarely. Post-2000 homes leak at predictable spots: the rim joist, the attic top plates, the hatch, and the floor over the garage. A blower door puts a number on it in an hour.
Is radon a Broomfield problem?
Every county in Colorado sits in the EPA’s highest radon zone. A test costs little, and a mitigation system reliably brings an elevated reading down.
