Replace your gas furnace with a heat pump for $8,500.
That’s the quote and that’s the invoice. Every line of what’s included — and what isn’t — published below, before you call. Heat this winter, air conditioning next summer, one system, one install.

Every tier is a fixed price for a standard changeout on serviceable ductwork. If your home needs something outside that, you’ll see the number before we order anything.
No rebate math. Nothing to chase.
If you’ve been shopping heat pumps, you’ve seen a lot of advertising built on incentives. Here’s what’s actually true for a gas-heated home in King or Pierce County this fall:
× The federal credit is gone
- The 25C tax credit — up to $2,000 off a heat pump — expired December 31, 2025. Installations after that date don't qualify. Some state and contractor websites still haven't updated their pages.
× Gas-to-electric rebates are income-limited
- PSE's rebate for switching from gas heat to a heat pump is income-qualified only. Most households that pay market rate get nothing toward a straight gas-furnace changeout.
So we compete on the number, not on the paperwork.
$8,500, all parts and labor, for a gas furnace changeout. Nothing to apply for, no six-week rebate processing, no income verification, no waiting on a check. The price on your quote is what you pay on install day.
Exactly what $8,500 buys — and what it doesn’t.
A fixed price is only worth something if you know where its edges are. Here they are.
+ Included
- Payne PH5SAN5 outdoor unit, sized to your home
- Matched indoor air handler with electric backup heat
- New refrigerant line set and electrical whip
- Programmable thermostat, installed and set up
- Hookup to your existing electrical panel
- City or county permit and inspection
- Removal and disposal of the old furnace and outdoor unit
- Startup and commissioning — charge verified, airflow checked, performance documented
× Not included
- Electrical panel upgrade, if your panel can't carry the new load
- Duct repair or replacement, if inspection finds leaks, undersized returns, or damage
- Gas line capping by a licensed plumber, where code requires it
- Asbestos or vermiculite abatement
- Crane, lift, or specialty access for difficult placements
- Structural or framing work for the pad, platform, or wall mount
If one of those comes up, here’s what happens.
You get the added cost in writing before we order a single piece of equipment — and you can walk away at that point with no charge and no pressure. We would rather lose the job at the quote than surprise you on install day.
What happens between your call and a warm house.
Fall is when every furnace in the county picks its moment. Here’s the actual sequence, so you know what you’re agreeing to before you agree to it.
- 01Same day
You call or book online
A person picks up, or calls you back the same day. Not a dispatch queue.
- 02At the visit
In-home evaluation and fixed written quote
We measure, look at your ductwork, check your panel, and hand you a number with the inclusions and exclusions listed on it.
- 03Once you sign
Equipment ordered, permit pulled
We file with your city or county and schedule the inspection.
- 04Install day
One day for a standard changeout
Old equipment out, new system in, site cleaned before we leave.
- 05After install
Startup, commissioning, inspection
We verify the charge and airflow, walk you through the thermostat, and meet the inspector.
Your install date goes on the quote.
Not “we’ll call you when we have an opening.” You see the date before you sign. If a permit office or a special-order part would push it, you hear that first — not after you’ve committed.
What a heat pump will and won’t do for a gas-heated house.
We’re not going to tell you this cuts your energy bill. Natural gas is cheap in Washington. When you move your heating from gas to electric, your gas use drops and your electric use climbs — PSE says the same thing on its own rebate pages. For most gas-heated homes, the bills roughly trade places.
So here is the honest case for doing it:
You're replacing a furnace anyway. If yours is 15–20 years old, you're buying heat this year or next. This is the version of that purchase that also cools the house.
Air conditioning, included, no second install. One outdoor unit does both. Adding AC separately later means a second system, a second crew, and a second permit — and Puget Sound summers keep making the case on their own.
Electric backup heat is built in. On the coldest nights the air handler's electric heat carries the load, so the house holds temperature through a cold snap.
A dramatically lower monthly bill. Anyone promising that for a gas-heated home in this region is selling you something.
Is this offer actually for you?
Your home is heated by a natural gas furnace, you're in King or Pierce County, and your ductwork is in serviceable shape.
You want it done before the cold, at a number you can see in advance.
Your home runs on electric baseboard or wall heaters with no ductwork. You want a ductless quote instead — call us and we'll price that separately.
Your ducts need full replacement, or this is new construction. Both are real jobs, just not this one.

“Great experience working with this team. They were responsive, very accommodating, and pricing was much more competitive than other companies that I called. Had them look at my system the next day and installed on the next business day after the weekend. Everything was installed smoothly, no issues, and the install crew was very professional and easy to work with. I would absolutely refer them.”Danny S.Verified Google review
