Common Furnace Problems and The Costs of Furnace Repair Knoxville TN

Thermostat Malfunctions

When your thermostat stops working correctly, your furnace won’t heat consistently. Repairs cost about $100–$300, while a modern smart thermostat upgrade can reach $600—but it offers long-term energy savings.

Ignition or Pilot Issues

Gas furnaces rely on a pilot light or ignition system to operate. If either fails, repairs typically range from $150–$400. Our experienced technicians can diagnose and fix these issues quickly.

Blower Motor Failures

A worn blower motor can lead to uneven heating or no airflow at all. Replacements cost around $300–$900, depending on your system’s make and model.

Carbon Monoxide Safety and Furnace Care

A damaged furnace, especially one with a cracked heat exchanger, can leak carbon monoxide—a colorless, odorless, and dangerous gas. Smith Heating and Air Conditioning’s certified technicians check for leaks and ensure your system operates safely. If you ever suspect a carbon monoxide issue, contact us immediately for furnace repair Knoxville TN services available 24/7.

When to Consider a Furnace Replacement

If your furnace is more than 15 years old or frequently needs repairs, replacement might be more cost-effective. A new furnace can cost between $3,500 and $7,500, but the energy savings and reliability are worth the investment. Our skilled heating contractors can help you determine whether repair or replacement is the best choice for your home.
