Furnace Installation Spokane
New Furnace Installation, Sized for Spokane Winters
A new furnace is a 15- to 20-year decision, and the install matters as much as the equipment. A furnace that’s too big short cycles and wears out early. One that’s too small runs nonstop on the coldest January nights. Cline’s sizes every furnace to your home, not to the old unit’s label.
We fix first and replace last, so if your current furnace still has good years left, we’ll tell you. When replacement is the better value, you’ll get clear options in writing, with upfront pricing, available rebates and financing laid out before you decide.
Know the Signs
Signs It's Time to Replace Your Furnace
Not sure it’s time? We’ll give you an honest repair-or-replace recommendation. If a repair makes more sense, we’ll say so and point you to furnace repair.
It's 15 to 20+ Years Old
Most gas furnaces last about 15 to 20 years. Past that, parts get harder to find, efficiency drops and the risk of a mid-winter failure climbs.
It Needs Repairs Every Winter
One repair is normal. A new igniter, then a motor, then a control board in back-to-back seasons usually means the money is better spent on a new furnace.
Your Avista Bills Keep Climbing
Older 60% to 80% furnaces waste a lot of the gas they burn. Moving to a 90%+ AFUE furnace can noticeably cut heating costs in a long Spokane winter.
Some Rooms Never Get Warm
Uneven heat often comes from an aging blower or a furnace that was never sized right. A properly sized two-stage or variable-speed furnace evens it out.
A Cracked Heat Exchanger
A cracked heat exchanger can let carbon monoxide into your home. It's one of the most common reasons we recommend replacement over repair.
Noise, Short Cycling or Lockouts
Banging, frequent on-off cycling or repeated lockouts on an older furnace are signs that major parts are wearing out at the same time.

Your Options
Furnace Options for Spokane Homes
As a Carrier Factory Authorized Dealer, we install Carrier furnaces and help you match the right one to your home, your budget and how long you plan to stay. A single-stage furnace runs at full blast every time. A two-stage furnace runs on low most of the time for quieter, more even heat. A variable-speed or modulating furnace adjusts in small steps for the most consistent comfort. Carrier’s Comfort, Performance and Infinity series cover all three.
| Standard-Efficiency Gas | High-Efficiency Gas | Electric Furnace | Dual-Fuel System | |
|---|---|---|---|---|
| Efficiency | 80% AFUE | 90% AFUE and up | Electric heat | Gas furnace plus heat pump |
| Best for | Rentals, or homes where PVC venting isn't practical | Most Spokane homes on natural gas | Homes without natural gas | Lower bills on mild days, plus summer cooling |
| Venting | Existing metal flue | PVC intake and exhaust | No flue needed | PVC, with a high-efficiency furnace |
| Avista gas furnace incentive | No | Yes, on qualifying models | Not a gas furnace | On a qualifying 90%+ furnace |
| Comfort options | Single- or two-stage | Single-stage, two-stage or variable-speed | Multi-stage heat | Two-stage or variable-speed |

Questions
Furnace Installation FAQs for Spokane Homeowners
How much does furnace installation cost in Spokane?
It depends on the furnace's efficiency and staging, the size your home needs, and whether venting, ductwork, gas or electrical work is needed. Cline's gives you options with upfront, written pricing before any work begins. For a quick ballpark, use the instant quote on our website.
How long does furnace installation take?
Most straightforward replacements are finished in a day. Jobs that need new venting, ductwork changes or a switch to a different fuel can take longer. We'll give you the timeline with your written estimate.
What size furnace do I need?
It depends on your home's square footage, insulation, windows, ductwork and layout, not the size of your old furnace. We measure your home and calculate its heating needs so the new furnace isn't too big or too small.
Should I choose an 80% or a 90%+ AFUE furnace?
For most Spokane homes on natural gas, a 90%+ AFUE furnace pays off over our long heating season and qualifies for Avista incentives. An 80% furnace costs less up front and can make sense for rentals or homes where PVC venting isn't practical.
Are there rebates or tax credits for a new furnace in 2026?
Avista offers up to $650 in Washington on qualifying gas furnaces rated 90% AFUE or higher, and $250 in Idaho for furnaces installed by December 31, 2026. The federal 25C tax credit for furnaces ended for systems installed after December 31, 2025. We'll confirm what your furnace qualifies for.
Gas furnace, heat pump or dual fuel: which is best?
If you have natural gas, a high-efficiency gas furnace is a reliable choice for Spokane winters. A dual-fuel system adds a heat pump that heats efficiently on milder days and cools in summer. Homes without gas often pair an electric furnace with a heat pump.
How long does a new furnace last?
Most gas furnaces last about 15 to 20 years. Yearly maintenance, clean filters and a correct installation all help a furnace reach the long end of that range.
Do you offer financing on new furnaces?
Yes. Financing is available, and we'll go over current plans when we give you your written options.
Do you install furnaces in Coeur d'Alene and North Idaho?
Yes. We install furnaces in Coeur d'Alene, Post Falls, Hayden and Sandpoint, as well as Spokane, Spokane Valley, Liberty Lake, Mead and Colbert.
