Family owned · Eatonville, WA
An honest comparison from a local team that installs both, so we don’t need to push either one.
For most South Sound homes, a heat pump is the stronger all-around choice because one system both heats and cools, and our mild, damp winters suit it. A high-efficiency gas furnace still makes sense if you have gas, want the lowest upfront price and don’t need cooling. A hybrid setup pairs the two.
Side by side
| Heat pump | High-efficiency gas furnace | Hybrid (heat pump + gas furnace) | |
|---|---|---|---|
| Heats your home | Yes | Yes | Yes |
| Cools your home | Yes | No (needs a separate AC) | Yes |
| Runs on | Electricity | Natural gas or propane | Electricity, with gas as backup on the coldest days |
| Flow Tech price range* | $9,250 – $24,000 (ducted) | $5,250 – $9,750 | Priced at your visit |
| Utility rebates (as of Oct 2026) | PSE and Ohop Mutual list rebates for eligible customers | PSE does not list a rebate for a gas furnace by itself | PSE lists rebates for adding a qualifying heat pump to a gas furnace |
| Usually best for | Most homes, especially those wanting AC or leaving baseboard or electric furnace heat | Gas homes that don’t want cooling and want the lowest upfront cost | Gas homes that want cooling plus gas backup during cold snaps |

How each one makes heat
A furnace burns gas (or propane) and blows the warm air through your ducts. Today’s high-efficiency models turn about 96% to 97% of their fuel into heat.
A heat pump doesn’t burn anything. It moves heat that’s already in the outdoor air into your home in winter, then runs in reverse to pull heat out in summer. That’s why it can replace both a furnace and an air conditioner.
What about cold snaps?
Our winters are mostly mild and wet, which is the kind of weather heat pumps handle well. When an arctic blast does roll through, a standard heat pump leans on its backup heat. If you’re up in the foothills or want the heat pump to carry the whole load, a cold-climate heat pump keeps heating strongly as temperatures drop. Another option is a hybrid system that hands off to your gas furnace on the coldest days.
Which costs less to run?
It depends on your home and on what you pay for electricity and gas, and both vary by utility. We’d rather not promise a savings number we can’t back up. At your free visit we can look at your bills with you and talk through what’s likely for your home.
Quick decision guide
A heat pump is probably your best fit if:
– you want air conditioning, or you’re replacing an old AC too
– you heat with baseboard, wall heaters or an electric furnace now
– you’re a PSE or Ohop Mutual customer who may qualify for a rebate
A new gas furnace may be the better call if:
– you already have gas and don’t care about cooling
– the lowest upfront price matters most right now
– your current furnace failed mid-winter and you need heat fast
Consider a hybrid if:
– you have gas, want cooling, and like the idea of gas backup on the coldest nights
Heat pump vs. furnace questions
Can a heat pump replace my gas furnace completely?
Yes. A properly sized heat pump, especially a cold-climate model, can heat a Western Washington home on its own. Some homeowners prefer to keep the furnace as backup in a hybrid setup.
Can I add a heat pump and keep my furnace?
Yes. That’s a hybrid, or dual-fuel, system. The heat pump handles most of the year and the furnace takes over on the coldest days. As of October 2026, PSE lists a rebate for adding a qualifying heat pump to a gas furnace.
Is a heat pump noisy?
Modern variable-speed heat pumps are quiet, because most of the time they run at low speed instead of switching fully on and off. We’ll help you choose a spot for the outdoor unit away from bedrooms and patios.
Do heat pumps work during power outages?
No. Heat pumps need electricity to run, and gas furnaces also need power for the blower and controls, so neither runs without power.
Which lasts longer, a heat pump or a furnace?
Both can last many years with yearly maintenance. A heat pump runs in summer and winter, so regular tune-ups matter. See maintenance plans
Will you tell me if my furnace just needs a repair?
Yes. If a repair makes sense, we’ll say so and show you the price before any work begins. Furnace repair
