Good, Better, Best in plain words
Good: 96% efficient single-stage furnace
A high-efficiency furnace that turns about 96% of its fuel into heat for your home. It runs at one level, on or off. Reliable warmth at a great price.
Better: 96% efficient two-stage furnace (Recommended for most homes)
Runs on a gentle low setting most of the time and switches to high on the coldest days. Quieter, steadier heat and fewer temperature swings.
Best: 97% efficient modulating furnace
Adjusts its output in small steps to match your home, with a variable-speed blower. The most even, quiet comfort we offer.
Thinking about a heat pump instead?
A gas furnace heats only. A heat pump heats and cools with one system. You can also pair a heat pump with a gas furnace so the furnace backs it up on the coldest days. Which costs less to run depends on your home and your gas and electric rates, and we’ll walk through it honestly at your visit. Learn about heat pumps · Compare heat pump vs. furnace
PSE gas customer? As of October 2026, PSE lists a $1,500 rebate for adding a qualifying ducted heat pump to your gas furnace, or $2,400 for income-qualified households. Rebates are not taken off the prices shown, are subject to PSE eligibility, funding is limited, and PSE can change or end offers at any time. See rebate info · pse.com/rebates/heating

Furnace questions
How much does a new furnace cost?
Our typical range for a new high-efficiency gas furnace runs from about $5,250 to $9,750, sales tax included for Eatonville, depending on your home’s size and whether you choose our Good, Better or Best option. Removal of your old furnace and permits are included. The final price is set at your free in-home visit.
Should I repair or replace my furnace?
It depends on the age and condition of your furnace and the cost of the repair. We’ll give you the repair price and, if it makes sense, the replacement price, so you can decide. We won’t pressure you either way.
What’s the difference between single-stage, two-stage and modulating?
A single-stage furnace runs at one level, on or off. A two-stage furnace runs on low most of the time and high on the coldest days. A modulating furnace adjusts in small steps to match your home. The more steps, the steadier and quieter the heat.
What does 96% efficient mean?
It means about 96% of the fuel the furnace burns becomes heat for your home. Older standard furnaces are around 80%.
Is removal of my old furnace included?
Yes. Removal and disposal of your old furnace is included on every job.
Do you pull permits?
Yes, permits pulled when required, and the permit cost is included in our price ranges.
Are there rebates on a new gas furnace?
As of October 2026, PSE doesn’t offer a rebate on a new gas furnace by itself. For PSE natural gas customers, PSE lists a $1,500 rebate for adding a qualifying ducted heat pump to your gas furnace (a “hybrid” system), or $2,400 for income-qualified households, and income-qualified households switching fully from gas heat to a heat pump may get $4,000. Rebates are subject to PSE eligibility, funding is limited, and PSE can change or end offers at any time. See rebate info
Do you work on propane and electric furnaces?
Yes. Propane furnaces, electric furnaces and manufactured-home furnaces are priced at your free in-home visit.
