When a heating system reaches the end of its life, most Vancouver homeowners face the same decision: replace it with another furnace, or switch to a heat pump. Neither answer is right for every house. The better choice depends on what fuel your home already has, how your ductwork is set up, how cold your rooms run in a January freeze, and how you weigh upfront cost against monthly bills.
Short answer: For most Vancouver homes, a heat pump is the better long-term choice. It heats efficiently in our mild winters, adds air conditioning, and at Clark Public Utilities' electric rates often costs less to run than gas. A high-efficiency gas furnace still makes sense if you have gas, a furnace in good shape and no need for cooling, and a dual-fuel system splits the difference.
This guide walks through how each system works, what each costs to run at local utility rates, and when a combination of the two makes the most sense.
What's the difference between a heat pump and a furnace?
A furnace creates heat. A gas furnace burns natural gas in a combustion chamber, and a heat exchanger passes that heat into air your blower pushes through the ducts. An electric furnace does the same job with resistance coils, much like a toaster. Either way, the furnace turns fuel or electricity directly into heat, and it can't turn out more heat than the energy it consumes.
A heat pump moves heat. A heat pump uses refrigerant to collect heat from the outdoor air, even cold air, and carry it indoors. In summer it runs in reverse and works as an air conditioner. Because it moves heat rather than making it, a heat pump can deliver two to three units of heat for every unit of electricity it uses across a heating season. We cover the refrigeration cycle in detail in How Heat Pumps Work in Vancouver WA.
That's the core difference: a furnace heats only, while a heat pump heats and cools with one piece of outdoor equipment.
Why Vancouver's climate suits heat pumps
Heat pumps lose efficiency as outdoor temperatures drop, which is why older units earned a poor reputation in cold regions. Southwest Washington's climate plays to their strengths. Average January lows here sit in the mid-30s, and most of the heating season runs between the upper 30s and the 50s, the range where heat pumps work most efficiently.
What we do get are a few short cold snaps each winter, often when east winds come down the Columbia River Gorge. Modern heat pumps, especially cold-climate models, keep producing usable heat well below freezing. Many systems also include backup electric heat strips for the coldest hours, or pair with a gas furnace as described below.
Our summers matter too. Vancouver now sees regular stretches of 90-plus-degree days, and plenty of homes that never needed air conditioning now want it. A heat pump covers both seasons with one system.
What each costs to run here
Operating cost comes down to local energy prices and equipment efficiency.
Electricity: Clark Public Utilities' residential rate is 8.79 cents per kilowatt-hour, plus a $19 monthly basic charge. That's low by national standards, and it's the main reason heat pumps pencil out well in Clark County.
Natural gas: NW Natural's Washington customers saw a rate increase take effect August 1, 2026, adding about $12.81 per month for a typical household using 54 therms a month. Further increases are already approved for August 2027 and August 2028.
A simple comparison: A 95% efficient gas furnace delivers about 95,000 BTUs of heat from one therm of gas. For a heat pump averaging a seasonal efficiency of about 2.3 units of heat per unit of electricity, producing the same heat takes roughly 12 kWh, or about $1.06 at Clark Public Utilities' rate. To compare this with your own bill, divide your total NW Natural gas charges for a winter month by the therms you used. If that figure is higher than about $1.06, a heat pump would likely cost less to run for the same heat.
If you heat with electric resistance today (an electric furnace, baseboard or wall heaters), the math is even clearer. The same 95,000 BTUs from resistance heat takes about 28 kWh, or roughly $2.45. A heat pump uses about 60% less electricity for the same heat, so switching often gives the biggest drop in your heating bill of any upgrade.
Your actual costs depend on your home's insulation, your thermostat habits, the specific equipment and how well it's sized, so treat these figures as a starting point, not a quote.
Upfront cost
A like-for-like furnace replacement is usually the lower upfront cost, especially when the ductwork, gas line and venting are already in place. A heat pump system usually costs more to buy, but compare it with the right alternative: if you'd otherwise buy a new furnace and a new air conditioner, a heat pump replaces both.
Costs vary widely with house size, ductwork condition, electrical service capacity and equipment tier, so a real number needs a site visit. Tri-Tech Heating, Inc. offers free estimates on all installations, and financing is available through Synchrony for qualified buyers.

Comfort and how the heat feels
The two systems feel different:
- A gas furnace delivers air at a high temperature, often 120°F or more at the register. It warms a cold house quickly, and many people like that blast of heat.
- A heat pump delivers air closer to 90–100°F and runs longer, steadier cycles. The result is more even temperatures with fewer hot-and-cold swings, though the air from the register feels less hot to the hand. Variable-speed heat pumps are especially good at holding a steady temperature and running quietly.
Ductless mini-split heat pumps add an option a furnace can't match. They heat and cool individual rooms with no ductwork at all, which suits older homes, additions, converted garages and rooms the central system never reached.
Lifespan and maintenance
A well-maintained gas furnace commonly lasts 15 to 20 years. A heat pump typically lasts around 15 years. It runs year-round for both heating and cooling, so it accumulates more operating hours than a furnace that sits idle all summer.
Both last longer with annual service. That means cleaning coils and burners, checking refrigerant charge or combustion, and testing the safety controls and defrost cycle. Tri-Tech Heating, Inc.'s Pre-Paid Preventative Maintenance Program (ESA) keeps that service on a schedule so it doesn't get skipped.
The middle option: dual-fuel systems
A dual-fuel, or hybrid, system pairs a heat pump with a gas furnace. The heat pump handles heating through most of the season, when it's the cheaper option, and the furnace takes over automatically below a set outdoor temperature or when gas becomes the cheaper fuel. You get air conditioning, lower operating costs through most of the winter, and the strong heat of a furnace during the rare hard freeze.
Dual fuel often works well for homes that already have gas service and a furnace in good condition, since the heat pump can be added alongside it.
Regulations and refrigerants to know about
Two industry changes may affect your decision:
- Refrigerants: Since 2025, new residential heat pumps and air conditioners have moved from R-410A to lower-global-warming refrigerants such as R-454B and R-32. New systems use the new refrigerants, and existing R-410A systems can still be serviced.
- Furnace efficiency rules: The Department of Energy adopted a rule requiring most new gas furnaces to be at least 95% efficient starting December 18, 2028. In June 2026 the U.S. Supreme Court sent the case back to the federal appeals court for reconsideration, so the final timeline is uncertain. Either way, high-efficiency condensing furnaces are already widely available.
Incentives in 2026
The federal 25C tax credit, which covered 30% of heat pump costs up to $2,000, expired on December 31, 2025, and does not apply to systems installed after that date. If your system was installed on or before that date, you may still be able to claim it; see the IRS Energy Efficient Home Improvement Credit page.
Clark Public Utilities offers rebates and low-interest loans for qualifying energy-efficiency upgrades. Eligibility depends on factors like your current heating type and whether an approved contractor does the work.

So which is right for your home?
In general:
- You heat with electric resistance today: a heat pump is almost always the better choice.
- You have no gas service: a heat pump, ducted or ductless, is the practical choice.
- You want air conditioning and need to replace your heating anyway: a heat pump covers both with one system.
- You have gas, a newer furnace, and want AC: consider adding a heat pump as a dual-fuel system.
- You have gas, an aging furnace, and no interest in cooling: a high-efficiency gas furnace remains a reasonable choice, but compare your per-therm cost with the heat pump figure above first.

Frequently Asked Questions
Is a heat pump a furnace?
No. A furnace creates heat by burning gas or running electric resistance coils, and it only heats. A heat pump moves heat from the outdoor air into your home, and it also cools in summer. The two can work together in a dual-fuel system.
Will a heat pump need a new electrical panel?
Not always. A heat pump typically needs a dedicated 240V circuit, and older or fully loaded panels sometimes need an upgrade. We check your panel during the estimate.
Are heat pumps loud?
Modern heat pumps are quiet, especially variable-speed models. Placing the outdoor unit away from bedroom windows and on a solid pad helps too.
