Furnace Repair in Chattanooga & North Georgia
Safe, Reliable Heat When You Need It
Winter cold snaps in the Chattanooga area don't last long, but they're exactly when a furnace is most likely to fail. Metro's technicians repair gas and electric furnaces of all major brands, getting heat back on quickly and safely.
Every repair starts with a full diagnosis: checking the thermostat, filter, ignition system, flame sensor, blower, limit switches and venting. On gas furnaces, we also inspect for cracked heat exchangers and venting problems that can lead to carbon monoxide risk.
We explain what failed, whether a repair makes sense for your furnace's age and condition, and give you an upfront price. When the heat goes out at night or on a weekend, our team is available 24/7.

Signs You Need Furnace Repair
Cold Air From the Vents
The blower runs but the air is cool, often due to an ignition, flame sensor or gas supply problem.
Turns On and Off Constantly
Frequent on-off cycling wastes energy and wears out parts. A clogged filter or overheating is a common cause.
Loud Bangs or Squeals
Banging, rattling, squealing or booming at startup means something inside needs attention.
Burning or Gas Smell
A persistent burning, electrical or gas smell is a safety concern. Shut the system off and call.
Yellow or Flickering Burner Flame
A healthy gas flame is blue. Yellow or flickering flames can mean incomplete combustion.
Heating Bills Keep Rising
Rising winter bills with normal usage often mean the furnace is losing efficiency.

Your Options
Getting the Heat Back On
Component Repair
Most no-heat calls come down to one failed component, like an igniter, sensor or motor, repaired in one visit.
Safety Inspection
We check for cracked heat exchangers, venting problems and carbon monoxide risk on every gas furnace we repair.
Repair vs Replace Review
For older or unsafe furnaces, we'll compare repair costs with the value of a new, efficient system.

What Affects the Cost of Furnace Repair?
Furnace repair cost depends on the part that's failed and the type of furnace. Igniters, flame sensors and thermostats are common, quicker repairs. Blower motors, control boards, inducer motors and gas valves involve more parts and labor. A cracked heat exchanger is a serious safety issue that usually means replacement.
We diagnose the problem, explain whether a repair is worthwhile for your furnace's age and condition, and give you an upfront price before work begins.
You always get the price before any work begins. Financing is available for qualified customers on larger jobs.
Expert Tip From Metro's Master-Certified Team
Three Checks Before You Call
Before calling for no heat, check three things: the thermostat is set to heat with fresh batteries, the furnace filter isn't clogged, and the furnace power switch, which often looks like a light switch near the unit, is on. These simple checks solve a surprising number of no-heat calls.

Frequently Asked Questions
Can't find what you're looking for? Our team is happy to help, day or night.
(423) 855-0967Why is my furnace running but not heating?
Common causes include a dirty filter, a failed igniter or flame sensor, a tripped limit switch, a thermostat problem or a gas supply issue.
Is it normal for my furnace to smell when it starts?
A brief burning-dust smell at the start of the season is normal. A persistent burning, electrical or gas smell is not. Turn the furnace off and call us.
Why does my furnace keep turning on and off?
Short cycling is often caused by a clogged filter, an overheating heat exchanger, a dirty flame sensor or an incorrectly sized furnace.
Is my gas furnace safe?
Gas furnaces can produce carbon monoxide if they're damaged or poorly vented. That's why annual inspections and working CO detectors matter.
When should I replace instead of repair?
If your furnace is 15 to 20 years old, needs a major repair or has a cracked heat exchanger, replacement is often the safer, better-value choice.
Do you offer emergency furnace repair?
Yes. No heat on a freezing night is an emergency. Call (423) 855-0967 any time.
