North Texas winters are mild until they aren't. When a hard freeze arrives and the furnace quits, we're the call that gets heat back in the house.
DFW furnaces sit idle for months, then get asked to run hard the moment a cold front drops temperatures 40 degrees overnight. That idle time is exactly why so many systems fail on the first genuinely cold night of the year — dust on the burners, a stuck igniter, a flame sensor coated from last season.
We repair gas furnaces, electric furnaces and heat strips, and heat pumps in heating mode across the Dallas–Fort Worth metroplex. Every heating call includes a combustion and safety inspection, because a furnace problem can be a health problem.
Gas heating equipment produces carbon monoxide, and its only safe exit is the flue. When a heat exchanger cracks or a vent gets blocked, CO can enter the living space — colorless, odorless, and dangerous.
That's why we inspect the heat exchanger, verify draft and flue integrity, check gas pressure, and test for CO on every heating repair. If we find an unsafe condition we'll tell you plainly and shut the equipment down rather than patch around it. If you ever smell gas, leave the house first and call the gas company, then call us.
Many DFW homes use heat pumps rather than furnaces, and heat pump air feels cooler at the vent than furnace air even when the system is working perfectly. That confuses a lot of homeowners into calling for a repair that isn't needed.
Real heat pump problems look different: the outdoor unit iced over and staying that way, auxiliary heat running constantly, or the system blowing cold air because a reversing valve or defrost board has failed. We diagnose which of those you actually have before quoting anything.
Almost every no-heat emergency we attend was preventable. A fall tune-up cleans the burners and flame sensor, tests the igniter before it strands you, verifies gas pressure, and catches a cracked heat exchanger while it's still a repair rather than an emergency replacement.
It's also the cheapest insurance in the house — and Comfort Club members get it twice a year along with priority scheduling on the cold nights when everyone calls at once.
Most often the burners aren't lighting — a failed igniter, a dirty flame sensor, or a lockout after failed ignition attempts — while the blower still runs. On a heat pump, cold air can mean a failed reversing valve or a system stuck in defrost. Both need a technician to confirm.
Igniters, flame sensors, and thermostats are inexpensive fixes. Inducer motors, gas valves, and control boards cost more, and a cracked heat exchanger usually points toward replacement. You get the exact price before we start the repair.
Yes, 24/7 across the metroplex. During a hard freeze we prioritize homes with no heat at all, especially those with infants, elderly residents, or medical needs.
Because they run so few hours here, gas furnaces often reach 15–20 years. The limiting factor is usually the heat exchanger and the age of the matched cooling equipment rather than the burner section.
Dust burning off the heat exchanger after months of no use is normal and clears within an hour of runtime. A persistent burning smell, an electrical smell, or a smell of gas is not normal — shut the system off and call us.
No. A cracked heat exchanger cannot be safely repaired, and running the furnace with one risks carbon monoxide exposure. Depending on the furnace's age and warranty status, the fix is either a heat exchanger replacement or a new furnace — we'll show you both paths.
