Furnace Repair in Columbia, SC — Book a Visit Today
A furnace that lights, runs a minute and shuts back down usually has a safety telling it something is wrong, and that is worth a look before the next cold snap. We do furnace repair in Columbia on gas and propane equipment, and we also handle heating repair on electric strips and air handlers. Short cycling, a burning smell that never clears, cold air from the vents or a blower that will not quit all point to different faults. If you ever smell gas, leave the house, call 911 or the gas utility from outside, then call us. Otherwise use the quote form.

Common furnace faults in Columbia homes
- 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.

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.
How soon can you get to my Columbia home?
Call us and we will give you a straight answer on the next available window rather than a vague promise. During July and August heat runs we book up fast, so morning calls usually get same-day or next-day attention. If your system is completely down and the house is climbing, say so when you call and we will prioritise accordingly.
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.
- All major brands, gas & electricOne independent crew for Carrier, Trane, Lennox, Goodman, Rheem and more.
- Straight answersNot worth fixing? We say that out loud, and often it saves you the visit fee.
