Don't get left in the cold.
Our Ohio experts can help.

Try the following troubleshooting tips:

• Clean or replace the air filter
• Make sure the pilot light is on
• Check your thermostat settings and power
• Make sure your furnace has power
• Check that the gas supply is open and you have enough fuel

If these measures fail to resolve the issue, or you are uncomfortable performing any of them, reach out to your local Trane technician for assistance.

Signs that your furnace isn’t working properly include:

• Abnormal odors or sounds
• Insufficient or uneven heating
• Visible signs of rust or cracks in the system

In some cases, your system may simply need regular servicing, but if your unit is aging or repairs will be more than $5,000, it may be time to consider replacement. Try out our $5,000 rule calculator to determine if repair or replacement is right for you.

Furnace repairs typically cost between $125 and $480. The exact cost depends on your system, the problem, and typical service rates in your area. You can reach out to a local technician for an estimate and financing options.

While homeowners can handle simple maintenance tasks like replacing the filter, it’s generally advised that you hire a professional for most furnace maintenance and repair needs. Not only can furnace repair be more complicated than it first seems, but there are potential dangers involved and working on the unit yourself may also void your warranty. Our Trane certified technicians have the expertise to make sure repairs are done fast and right.

Some of the most common furnace issues include, but are not limited to:

• Dirty filters
• Dirty ductwork
• Broken thermostat
• Ignition or pilot light issues
• Damaged limit switch

If your furnace is having trouble, isn’t operating as it should, or you have any concerns about maintenance or repair, contact your local Trane technician for help.
