Quick answer
Converting from gas to a heat pump works well in our mild climate, but it's not automatically the right call for every home — gas is competitively priced here, so the case usually rests on adding cooling, simplifying to one system, and moving off fossil fuel, not on dramatic bill savings. A dual-fuel system that keeps your furnace as backup is often the smartest first step, and it's a configuration we install and service alongside full conversions.
- Heat pump conversions from gas are about cooling, simplicity, and electrification — be skeptical of guaranteed-savings pitches.
- Dual-fuel (heat pump + your gas furnace as backup) is a legitimate middle path, not a compromise.
- Heat pump heat feels different from furnace heat: lower supply temperatures, longer and gentler run times.
- Panel capacity and duct condition are the two site factors that most often shape the project.
- Clark Public Utilities' heat pump rebates apply to electrically heated homes — not gas conversions — so verify before counting on them.
When does replacing a gas furnace with a heat pump make sense?
The clean cases first: your furnace is near end of life anyway, you don't have central AC and want it, or you've decided to move the house off gas. In those situations a heat pump answers several questions with one system — replacement heat, new cooling, and one piece of equipment to maintain instead of two. Our climate helps: winters mild enough that the heat pump rarely needs help, summers now warm enough that cooling is no longer optional for many families (see why heat pumps fit the PNW).
The honest counterpoint: if your gas furnace is mid-life and healthy and you already have AC you're happy with, the conversion math is much softer. Natural gas is competitively priced in SW Washington, so operating-cost savings alone rarely justify retiring working equipment early. We'd rather tell you that up front than sell you a conversion you didn't need.
What's a dual-fuel system, and why do we often recommend it?
Dual-fuel pairs a heat pump with a gas furnace in the same air handler cabinet. The heat pump — the efficient half — carries the bulk of the season; below a configured switchover temperature the furnace takes over. You get heat pump efficiency for the mild 90-something percent of PNW winter hours, furnace muscle for Gorge-wind cold snaps, and summer cooling from the same outdoor unit.
It also de-risks the decision: you keep gas service and a familiar backup while finding out how a heat pump actually performs in your house. Many homeowners who start dual-fuel go all-electric at the furnace's natural end of life. Home Energy Group installs both configurations, along with furnace replacement and fuel-conversion work, so the recommendation you get is based on your home — not on what we happen to sell.
What changes about comfort and the house itself?
Heat pump heat feels different. A gas furnace blasts short cycles of very hot air; a heat pump delivers cooler supply air over longer, gentler run times, holding temperature more evenly. Most people prefer it once they adjust — but you should know before, not after.
Two site factors shape almost every conversion quote:
- Electrical capacity. A heat pump plus backup strips draws real amperage; older 100-amp panels sometimes need an upgrade, which belongs in the budget conversation from day one.
- Ductwork. Because supply air is cooler, airflow matters more. Ducts that limped along with a furnace can undermine a heat pump — our duct design & sealing guide explains why we test rather than assume, and our own sheet-metal shop fabricates what fixes need.
What rebates apply to a gas-to-heat-pump conversion?
Here's where honesty beats marketing: Clark Public Utilities' heat pump rebates ($500–$1,250) are for electrically heated homes — an electric furnace or zonal-heat conversion qualifies; a gas furnace conversion generally does not. On the Oregon side, Energy Trust of Oregon runs heat pump incentives for customers of participating utilities with their own eligibility rules. And the federal energy-efficiency tax credit expired for equipment placed in service after December 31, 2025 — so treat any pitch still promising it with suspicion.
Programs shift year to year. Rather than promise a number this page can't guarantee, ask us about current rebates when you get a quote — we check what your specific project qualifies for, and our rebates guide tracks the verified programs.

Common questions
Will a heat pump lower my bill compared to a gas furnace?
Not necessarily — gas is competitively priced in SW Washington, so the operating-cost comparison is closer than heat pump marketing often implies. Conversions from electric resistance heat save dramatically; conversions from gas are usually justified by adding cooling, simplifying to one system, and electrification goals. We'll run your actual numbers rather than promise savings.
Can I keep my gas furnace as backup?
Yes — that's a dual-fuel system, and it's often what we recommend. The heat pump handles the mild majority of the heating season plus summer cooling, and your furnace takes over automatically on the coldest nights. It's a low-risk way to get heat pump benefits without giving up gas.
Do gas-to-heat-pump conversions qualify for utility rebates?
Usually not the big local ones — Clark Public Utilities' heat pump rebates target electrically heated homes. Energy Trust of Oregon has separate incentives for Oregon customers of participating utilities. Programs change, so ask us to verify what your project qualifies for before you count on any rebate.
Does my electrical panel need upgrading for a heat pump?
Sometimes. A heat pump with electric backup strips draws significant amperage, and older 100-amp panels can be at their limit. We evaluate panel capacity during the quote so an upgrade — if needed — is in the budget from the start, not a surprise mid-project.
