Furnace & Heating Repair
Heating systems in North Texas sit idle for most of the year and then get asked to perform during a hard cold snap. That pattern is exactly why so many failures happen on the first genuinely cold night — components that were marginal in March finally give up in December.
A gas furnace repair is never only about restoring heat. Combustion safety is part of every visit: heat exchanger condition, venting, gas pressure, and flame characteristics. A cracked heat exchanger can put carbon monoxide into the living space, and that is not something to find out the hard way.
We service gas furnaces, electric furnaces and heat pump systems, and we answer around the clock during cold weather.
When you need furnace repair
The symptoms homeowners actually describe when they call us — and what each one usually means.
It will not ignite, or tries and gives up
Modern furnaces make several ignition attempts and then lock out. Common causes are a failed igniter, a dirty flame sensor, a pressure switch reading a venting problem, or a gas supply issue. A dirty flame sensor is one of the least expensive repairs there is and one of the most common.
It runs but blows cool air
The blower is working and the burner is not — or the burner lights and shuts down almost immediately on a safety limit. Either way, something is stopping combustion from being sustained.
It cycles on and off rapidly
Overheating and tripping the high limit, usually because airflow is restricted. A loaded filter, closed registers, or a duct problem starves the heat exchanger of the air it needs to shed heat.
A burning smell that does not clear
Dust burning off on the first run of the season is normal and passes within a short while. A burning smell that persists, or smells electrical or acrid, means shut it off at the thermostat and the breaker and call.
Yellow flames instead of blue
A gas furnace should burn crisp blue. Yellow or lazy orange flames indicate incomplete combustion, which produces carbon monoxide. This is a stop-and-call-us signal, not something to monitor.
A carbon monoxide detector going off
Get everyone out of the house and call the fire department first, then us. Do not re-enter to investigate. Every home with gas appliances needs working CO detectors — this is the item on the list that saves lives.
What actually happens on the job
No mystery, no vague diagnosis. Here is the sequence we follow every time.
Safety checks come first
Heat exchanger inspection, venting and draft verification, gas pressure and combustion characteristics. If we find a cracked heat exchanger, we red-tag the equipment and tell you plainly — this is the one situation where continuing to run a system is not an option we will leave open.
Diagnose the sequence, not the symptom
A furnace runs a defined startup sequence. Watching where it stops — call for heat, inducer, pressure switch, igniter, gas valve, flame sense, blower — points directly at the fault instead of parts-swapping.
Repair with genuine parts
Igniters, flame sensors, pressure switches, inducer motors, gas valves, control boards and blower components. Most furnace repairs are single components and they are frequently modest.
Verify and clean up
Run a full heating cycle, confirm temperature rise is within the equipment’s specification, recheck draft and combustion, and clean the burner assembly while we are in there.
The problem with heating equipment in a warm climate
Furnaces here run a fraction of the hours they would in a northern state, which sounds like it should mean they last forever. In practice the opposite pattern shows up: long idle periods let dust settle on burners and flame sensors, rodents and insects find their way into idle equipment, and nobody notices a developing problem because the system is off for eight months. Then a hard freeze arrives, every furnace in the metro fires at once, and the marginal ones fail simultaneously — which is also when every HVAC company in the area is at capacity. The practical takeaway for North Texas homeowners is that a fall heating check has an outsized value here specifically because the equipment sits unused so long. Ten minutes of cleaning a flame sensor in October prevents the 2 a.m. no-heat call in January.
Straight talk on pricing
Most furnace repairs are single-component and land at the more affordable end of HVAC work — flame sensors, igniters and pressure switches particularly. Inducer motors, gas valves and control boards are more substantial. A cracked heat exchanger is the exception that changes the conversation entirely, because that part is often a large fraction of the cost of a new furnace and replacement usually makes more sense. We tell you which category you are in before doing anything.

Why does my furnace start and then shut off after a minute?
That pattern usually means the burner lights and then a safety device shuts it down. The two most common causes are a dirty flame sensor — the furnace lights, cannot confirm flame, and closes the gas valve as designed — and overheating from restricted airflow tripping the high limit. Check your filter first; a badly loaded filter causes the second one regularly. The flame sensor is an inexpensive service item.
Is a cracked heat exchanger really that serious?
Yes, and it is not a judgment call. The heat exchanger is the barrier between combustion gases and the air circulating through your house. A crack lets combustion products — including carbon monoxide — into the airstream. We are required to shut the equipment down when we find one, and we will explain exactly what we saw. Replacement of the furnace is usually the sensible route, because an exchanger is a large portion of the equipment cost.
Do I need a carbon monoxide detector if my furnace is new?
Yes. Age is not protection. Any home with gas appliances — furnace, water heater, range, fireplace — should have working CO detectors, and they need to be on every level and near sleeping areas. They have a service life of their own and should be replaced at the interval printed on the unit. This is the cheapest safety equipment you will ever buy.
My furnace smells like burning when I turn it on for the first time each winter.
Dust that settled on the heat exchanger over eight idle months burning off. It is normal, and it should clear within the first cycle or two. What is not normal is a smell that persists past that, a smell that is electrical or acrid rather than dusty, or any smell of gas. Those mean shut it down and call.
