Furnace Repair & Replacement Cost in Ohio
Most Ohio homes heat with a natural-gas furnace in the basement, and it runs five to six months a year. Here is what repairs and new systems actually cost, and how to tell which one you need.
New system prices in Ohio
Statewide typical ranges, installed. City pages adjust these for local labor costs.
80% AFUE gas furnace
Same-spot swap of a standard-efficiency furnace that vents through the existing chimney liner. Lowest upfront price.
95–97% AFUE gas furnace
Condensing furnace with PVC venting and a condensate drain. Uses roughly 15% less gas than an 80% unit in an Ohio winter.
Two-stage / variable-speed
Quieter, more even heat and better humidity control. Worth it in larger or two-story homes with hot and cold rooms.
Common repair prices
| Repair | Typical price |
|---|---|
| Diagnostic visit | $100 – $150 |
| Flame sensor clean / replace | $100 – $250 |
| Hot surface igniter | $150 – $400 |
| Inducer motor | $400 – $900 |
| Blower motor | $450 – $1,200 |
| Control board | $350 – $900 |
| Gas valve | $300 – $750 |
| Heat exchanger (if under warranty: labor only) | $1,200 – $3,000 |
Parts and labor, before any warranty coverage. Emergency, night and weekend calls usually add $100–$250.
Signs it is time to replace
- The furnace is 15–20+ years old and needs a repair over about $800
- A technician finds a cracked heat exchanger or red-tags the unit for carbon monoxide
- Gas bills keep climbing although the thermostat setting has not changed
- Some rooms never get warm and the blower runs constantly
- It short-cycles: turns on and off every few minutes
Repair or replace? A simple Ohio rule of thumb
Multiply the age of the furnace by the repair quote. If the result is more than about $5,000 (for example a $400 repair on a 14-year-old unit), most technicians will suggest pricing a replacement. Under that, a repair usually makes sense.
A cracked heat exchanger is the exception. It can leak carbon monoxide into the home, and on an out-of-warranty furnace the repair often costs half the price of a new unit. If you are told the heat exchanger is cracked, ask to see the photo or camera footage and get a second opinion before you sign anything.
80% or 95% AFUE in Ohio?
An 80% furnace turns 80 cents of every gas dollar into heat; a 95% unit turns 95 cents. In a typical Ohio home that burns 700–900 therms a year, the difference is roughly $100–$200 a year at current gas prices, so the extra $1,200–$2,500 for a condensing furnace pays back in 8–15 years.
The deciding factor is often venting. A 95% furnace vents through PVC pipe out the side wall, which frees the old chimney but needs a condensate drain and a spot outside away from windows and snow drifts. In older Cleveland, Cincinnati and Youngstown homes where the water heater still shares the chimney, the installer may also need to reline the chimney for the water heater. Ask for that line item up front.
What a fair furnace quote includes
A complete quote should list the brand and model number, AFUE, the size in BTU (based on a heat-load calculation, not just the old unit's label), new venting, gas line and condensate connections, removal of the old unit, the permit, and the parts and labor warranty in years.
Get two or three quotes. In Ohio, prices for the same furnace can differ by $2,000 or more between companies, mostly because of overhead and how busy they are. Late fall and the first cold snap are the busiest weeks; early fall and spring are the easiest time to negotiate.
FAQ
How much does a new furnace cost in Ohio in 2026?
Most Ohio homeowners pay $3,400–$5,800 for a standard 80% AFUE gas furnace and $4,600–$8,400 for a 95–97% high-efficiency model, installed. Two-stage and variable-speed units run $6,200–$10,500.
How long does a furnace last in Ohio?
A well-maintained gas furnace usually lasts 15–20 years in Ohio. Long heating seasons and dirty filters shorten that; an annual tune-up and a filter change every 1–3 months extend it.
Is there a federal tax credit for a new furnace in 2026?
No. The federal 25C energy-efficiency credit ended for equipment placed in service after December 31, 2025. Check your gas and electric utility for any current rebates and ask installers about manufacturer promotions instead.
Can a furnace be replaced in one day?
Yes. A same-spot furnace swap usually takes 4–8 hours. Switching from 80% to 95% with new PVC venting or adding a new AC coil at the same time can push it to a day and a half.
Why does my furnace smell like burning when it first turns on?
A dusty smell for the first few minutes of the season is normal: dust burning off the heat exchanger. A smell that persists, an electrical burning smell, or any rotten-egg gas odor is not. For gas odor, leave the house and call your gas utility from outside.
