TL;DR
- American Fork’s 84003 has older housing than neighboring Lehi: the median home was built in 2001 (Lehi’s 84043: 2008), and 48% of housing units predate 2000 (ACS 2020–2024).
- Many original furnaces and ACs from the late 1990s and early 2000s are past the 15-to-20-year span furnace makers commonly cite, so replacement conversations are common, often for both pieces at once.
- 84% of occupied homes heat with utility gas. Enbridge Gas ThermWise furnace rebates apply; Wattsmart dual-fuel rebates apply if your electricity is from Rocky Mountain Power.
- Free request; licensed shops that serve your ZIP may reach out. We don’t install, dispatch, or quote.

What the numbers suggest
General context, not a diagnosis:
- Nearly half of housing units were built before 2000. In those homes, the furnace and AC may have been replaced once already, or may still be original. Knowing which (and roughly when) is the most useful thing to tell a shop.
- Replacing both at once is a common conversation when the furnace and AC are the same age. Our AC and heat pump page explains the AC-only, dual-fuel, and all-electric paths.
- Older ductwork and venting. If a bid moves you from an older 80% AFUE furnace to a 90%-plus condensing model, it usually needs new PVC venting and a condensate drain. Ask whether that, and any duct repairs, are in the price.
American Fork’s heating season
Utah County winters are close to Salt Lake’s. At the Provo BYU weather station, NOAA’s 1991–2020 normals show about 4,968 heating degree days a year, climbing from 327 in October to 995 in December and 1,007 in January (NOAA monthly normals; annual). Provo is the Utah County station we used, so treat it as a regional guide rather than a reading for your street.
Utilities and rebates
- Gas: Enbridge Gas ThermWise listed $300 for a 95%–97.4% AFUE gas furnace and $350 for 97.5% AFUE or higher with an ECM blower, plus $700–$1,200 for qualifying dual-fuel systems, on October 7, 2026 (ThermWise).
- Electric: if your bill says Rocky Mountain Power, Wattsmart listed up to $1,450 for an AHRI-rated dual-fuel heat pump system ($700 if not AHRI-rated), installed by a participating contractor in an existing single-family home (Wattsmart).
- Federal: the 25C tax credit isn’t allowed for equipment placed in service after December 31, 2025 (IRS).

Permits in American Fork
Furnace and AC replacements normally need a mechanical permit and inspection. American Fork’s Building Department is the place to confirm requirements. Ask your contractor whether the permit is included in the bid.
Check the license before work starts
Before anyone works on your system, look the company up on DOPL’s free Licensee Lookup & Verification. You want an Active status and an HVAC classification (H100, or the older S350), under the same business name that’s on your estimate. Step-by-step: how to check a Utah HVAC license.

How we put this page together
This page was written by the Utah HVAC Connect editorial team, not by a contractor. We used public data only: NOAA 1991–2020 climate normals, U.S. Census Bureau American Community Survey (ACS) estimates, and the rebate, permit, and licensing pages published by Utah utilities, cities, and DOPL, each checked on the date shown above. For this page we also pulled ZIP-level housing data and checked the city’s own building and utility pages. We don’t publish prices we can’t source, contractors can’t pay to be mentioned here, and we don’t name partner shops on this page. Programs and rules change, so confirm details with the program or your contractor before you sign anything. See our editorial policy. Spot an error? Email hello@lendifi.io.

FAQ
My American Fork home was built in the 1990s. What should I ask an HVAC shop?
Ask whether your furnace and AC are original or replacements, what condition the ductwork and venting are in, and, if replacement comes up, whether the bid covers venting changes, permit, and haul-away. We don’t recommend equipment; licensed shops assess on site.
Which rebates apply in American Fork?
Gas furnace and dual-fuel rebates come from Enbridge Gas ThermWise. If your electricity is from Rocky Mountain Power, Wattsmart lists dual-fuel heat pump rebates. The federal 25C credit ended for equipment placed in service after December 31, 2025.
Do I need a permit to replace a furnace or AC in American Fork?
Normally, yes. American Fork’s Building Department handles permits; most homeowners have the contractor pull it.
Do you cover Pleasant Grove, Highland, or Cedar Hills?
Enter your ZIP on the Get Help form. Matching depends on licensed shops that serve your ZIP.
Is the request free, and do you send the technician?
The request is free for homeowners with no obligation to hire. We don’t send technicians or quote; we’re a matchmaker that connects you with licensed Utah HVAC shops that serve your ZIP. Contractors who receive leads pay us.
