Service
Furnace Repair
North Texas nights still drop below freezing. A furnace that will not light, or one that smells wrong, gets a combustion and safety check before we talk about parts.
Common problems
No heat, fan runs
Failed igniter, flame sensor, or a pressure switch that is telling the truth about the vent.
Short bursts of heat
Often a dirty filter, a weak blower, or a limit switch doing its job.
Yellow burner flame
That is a combustion problem. We shut it down and fix the air or the gas path.
Clicking, then nothing
Control board or a safety lockout. We read the fault code instead of swapping parts at random.
How a visit goes
01
Safety first
If you smell gas, leave. We will not ask you to reset anything.
02
Diagnose
Sequence of operation, from thermostat call to steady flame.
03
Quote
Repair cost next to the age of the furnace, so the choice is obvious.
04
Verify
Temperature rise and a CO reading before we call it done.

“No heat on a Sunday night. The tech checked the heat exchanger before selling me an igniter, which is the order I wanted. Clear invoice, shoe covers, gone in an hour.”
“They could not get the part until morning and told me that upfront. Space heaters recommendation was practical. Tech was back at 8:05.”
