Gas Furnace Repair in Durham, NC
Gas furnace repair across Durham starts with the safety side: if you smell gas or a carbon monoxide alarm sounds, get everyone out of the house, call 911 or your gas utility from outside, then call us. With that ruled out, the usual culprits are a dirty flame sensor, a lazy igniter, a pressure switch reading a blocked flue, or a limit tripping on restricted airflow. We test the sequence of operation end to end. Call or use the quote form to book a visit.

What brings Durham homeowners to this job
- It runs a few minutes then shuts off, over and over Short cycling from restricted airflow, an overheating limit switch or a dirty filter
- Nothing happens at all when I turn the heat on Thermostat, control board, transformer or tripped breaker on the circuit
- There is a loud bang when the burners light Delayed ignition from a weak ignitor or dirty burners, worth looking at soon
What we check on the unit
We check the flame sensor and igniter, the gas valve and manifold, pressure switch and hose for blockage, the inducer motor, the blower motor and capacitor, limit switches and the control board. We inspect the heat exchanger for cracking and look at the flue and venting, which matters in older homes across the region where terminations get blocked. Return air and duct condition get a look too. In damp crawlspaces the ductwork and the furnace cabinet both take a beating, and that shows up as poor airflow.
How we decide repair is the right call
We weigh the age of the furnace, the part that failed, and what else is close behind it. A flame sensor, igniter or pressure switch on a mid-life furnace is a straightforward fix and worth doing. A cracked heat exchanger is different, because that is a combustion safety issue and we will shut the unit down and talk replacement. If a furnace is well past its service life and needs a major component, we lay out both paths with what we found and let you decide.

My furnace lights then shuts off after a minute. What is that?
Usually a dirty flame sensor, a limit trip from restricted airflow, or a venting problem. Change the filter and make sure supply vents are open. If it keeps cycling, book a heating repair visit so we can watch the full sequence.
Should I keep resetting the furnace when it locks out?
Once is reasonable. Repeated resets are not. A lockout means the control board detected a fault, often related to gas, flame or venting, and forcing it to retry can make things worse. Call us instead.
How soon can you get to my house in Durham?
Call us and we will give you a real window rather than a vague promise. During a July heat stretch or the first hard freeze in January the board fills up fast, so the earlier in the day you call, the better your odds of same-day service. If your system is completely down we try to work you in ahead of routine maintenance visits.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form. We ask what changed, when it started, and what the thermostat reads against the actual room temperature. That short conversation tells us what parts to load on the truck.
- Step 2
We diagnose on site
A technician checks the thermostat, the electrical side, airflow through the filter and coil, refrigerant behaviour and the outdoor unit. You get a plain explanation of what failed and why, before any work starts.
- Step 3
Repair and verify
We make the repair, then run the system through a full cycle and measure temperatures at the supply and return. If something upstream caused the failure, we tell you so it does not repeat.

Why homeowners call us
- We know salt airCoastal homes lose condenser coils to salt corrosion years before inland systems do. We look for fin damage and pitted line sets on every visit, because a clean-looking unit can still be shedding capacity from the outside in.
- Humidity is part of the jobHurricane-season air loads a system in ways a temperature reading will not show. If your house feels clammy at 74 degrees, we look at run times, airflow and drainage rather than just adding refrigerant and leaving.
- Crawlspace realitiesHigh water tables mean wet ground under ductwork, rusted plenums and condensate lines with nowhere good to drain. We check what is happening under the floor, since that is often where comfort problems actually begin.
- Straight answersWe tell you what failed, what it will take to fix, and whether a repair makes sense on an older system. No pressure to replace something that has honest years left in it, and no vague diagnosis.
