Ohio winters average 26°F in January in Cleveland and 28°F in Columbus. A failed furnace isn't an inconvenience — it's a genuine emergency. Our network of licensed Ohio HVAC contractors offers same-day and after-hours furnace repair statewide.
Cleveland averages 57 inches of snow per year and regularly sees January lows below 20°F. Columbus, Dayton, and Cincinnati are hardly mild — all three cities see stretches of single-digit temperatures during winter weather events. Northeast Ohio deals with lake-effect cold on top of normal Ohio winters. Your furnace isn't optional in this state.
When your furnace stops working in January, every hour matters. The Ohio HVAC Pros network includes contractors who cover every Ohio county with same-day and emergency after-hours furnace repair.
The igniter lights the gas burner. When it fails, your furnace attempts to start, fails, and enters lockout mode. You'll hear the furnace try to ignite (usually 2-3 times) and then shut off. Igniter replacement is one of the most common furnace repairs in Ohio — typically $100-$200 for parts and labor.
The flame sensor tells the furnace that the burner actually lit. Dirt buildup prevents it from reading the flame properly, causing the furnace to shut off as a safety measure. A cleaning or replacement costs $80-$150 and takes an experienced technician about an hour.
The blower motor circulates heated air through your ductwork. Symptoms include weak airflow, unusual squealing or grinding noises, or the heat running but rooms staying cold. Blower motor replacement runs $300-$600 depending on the unit.
This is the most serious furnace problem and requires immediate action. A cracked heat exchanger allows combustion gases — including carbon monoxide — to mix with your home's air. If a technician diagnoses a cracked heat exchanger, the furnace must be shut down immediately. In most cases, the age of the furnace makes replacement the right call rather than a costly repair.
The pressure switch monitors the furnace's draft and combustion process. A failed pressure switch typically prevents the furnace from starting at all. Replacement costs $150-$250.
| Repair Type | Typical Cost | Notes |
|---|---|---|
| Igniter replacement | $100 – $200 | Very common, quick repair |
| Flame sensor cleaning/replacement | $80 – $150 | Often a maintenance item |
| Pressure switch | $150 – $250 | May indicate venting issue |
| Blower motor | $300 – $600 | Varies by motor size |
| Control board | $300 – $700 | Can be expensive on older units |
| Gas valve | $250 – $500 | Licensed gas work required |
| Heat exchanger replacement | $1,500 – $2,500+ | Often warrants full replacement |
| Diagnostic fee | $75 – $150 | Applied toward repair cost |
| Emergency after-hours | +$50 – $150 | Added to standard repair cost |
A rough rule that most Ohio HVAC professionals use: multiply the furnace's age by the repair cost. If the result exceeds $5,000, replacement is usually the better investment. For example, a 20-year-old furnace needing a $400 repair = $8,000 — replacement is likely smarter.
