Furnace Repair — Book a Visit Today
We handle furnace repair and heater repair for homes across Alabama, Georgia, Kentucky, North Carolina, South Carolina and Tennessee, and the fastest next step is to call us with what the furnace is doing right now. Most no-heat calls come down to a cracked ignitor, a dirty flame sensor, a failed blower motor or capacitor, a clogged filter choking airflow, a bad limit switch, or a thermostat that lost its signal. A visit starts with your description, then we read the control board, check gas pressure or electric heat elements, test airflow and look at the flue. You get the finding and the options before we touch a part. If you smell gas, leave the house first and call 911 or your gas utility.

The furnace symptoms we hear most
- The furnace blows but the air is cool Ignition failure, flame sensor, or a heat call that never completes
- It fires up, runs a minute, then quits Short cycling from a dirty flame sensor, blocked airflow or a tripped limit switch
- Nothing happens at all when I raise the thermostat Thermostat power, tripped breaker, blown low voltage fuse or failed control board
- There is a loud bang when the heat kicks on Delayed ignition or duct expansion, both worth looking at before the next cold snap
- Some rooms are freezing and the rest are fine Airflow and duct problems, an undersized blower, or a stuck zone damper
Whether you call it furnace repair, heating repair or heater repair, the work is identical and so is the quote you approve first.
Safe things to check first
Worth a look before you call — sometimes it saves you the visit.
- 1 Check the thermostat: fresh batteries, set to heat, and the temperature set above the room reading.
- 2Look at the electrical panel for a tripped breaker to the furnace or air handler and reset it once.
- 3Pull the filter. If it is grey and matted, replace it, because a starved furnace will shut itself down on high limit.
- 4Walk the house and confirm supply and return vents are open and not blocked by furniture or rugs.

My furnace stopped overnight. How fast can someone come out?
Call us and tell us there is no heat and how cold the house is. No-heat calls get moved up the schedule, especially with children, older adults or pets in the home. We will give you an honest arrival window rather than a guess.
Is it worth repairing an older furnace?
Often yes, if the heat exchanger is sound and parts are still available. We look at age, repair history and what failed. A capacitor or ignitor is a small fix. A cracked heat exchanger is a replacement conversation, and we will say so plainly.
What does a flame sensor actually do?
It proves to the control board that a flame is present so gas keeps flowing. Once it is coated with residue it stops sensing, and the furnace shuts down within seconds of lighting. Cleaning or replacing it is one of the most common heating repair fixes we make.
I smell gas near the furnace. What should I do?
Get everyone out of the house first. Do not touch switches or the thermostat. From outside, call 911 or your gas utility and let them make the area safe. Once they clear it, call us and we will inspect the furnace and gas train.
Do you work on electric furnaces too?
Yes. Electric furnace repair usually involves heat strip elements, sequencers, contactors, the blower motor or a limit that opened. We test each element under load rather than swapping parts blind, so you only pay for what actually failed.
Why does my furnace trip the breaker?
Something is pulling more current than the circuit allows, often a failing blower motor, a shorted heat element or a wiring fault. Reset it once. If it trips again, stop and call us, because repeated resets on a fault are a fire risk.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form and describe what you hear, smell or feel. Warm air, short cycling, a breaker that keeps tripping. That gives us a head start on the likely cause.
- Step 2
We diagnose on site
A technician checks the thermostat, airflow, electrical connections, refrigerant performance and the outdoor unit. We work the crawlspace and the attic too, because ductwork and drainage cause more trouble than people expect.
- Step 3
You decide, then we fix it
We explain what failed, what it takes to repair it, and what we would watch next season. No work starts until you say go. Most repairs finish the same visit when parts are on the truck.

Why homeowners call us
- Mixed heating is normal to usHeat pumps, propane furnaces and dual-fuel setups all behave differently in cold weather. We know how a heat pump should sound in the thirties and when the backup heat is doing too much of the work.
- We go under the houseRed clay crawlspaces hide crushed ducts, sweating lines and standing water. Comfort problems often start down there, not at the unit, so we look before we start replacing parts you may not need.
- Plain explanationsYou get told what broke and why, in words that make sense. If a repair is a short-term patch on an aging system, we say that out loud so you can plan instead of guessing.
- One crew, six statesWe serve homeowners across Alabama, Georgia, Kentucky, North Carolina, South Carolina and Tennessee. Same approach in every one: show up, diagnose properly, repair what needs repairing, leave the space clean.
