Furnace Repair in Duncanville — quick answers

My furnace quit overnight. How soon can someone come out?

Call us and tell us the house is cold. No-heat calls get moved up, especially with small children, older adults or hard freeze temperatures in the forecast. Before we arrive, check the thermostat, the breaker and the filter so we can start further down the list.

What is a flame sensor and why does it keep failing?

The flame sensor is a small rod that proves a flame is present. Combustion residue builds a film on it, the furnace stops seeing flame and shuts down for safety. Cleaning or replacing it is a common repair, and repeat failures usually point to burner or airflow problems.

Do you repair electric furnaces too?

Yes. Electric furnaces and air handlers with heat strips fail differently, usually a burned sequencer, an open limit switch, a failed contactor or a blower motor. It is high voltage work, so leave the panel closed and let us open it.

I smell gas near the furnace. What do I do?

Leave the building right away, do not flip switches, and call 911 or your gas utility from outside. Let them make the house safe first. Once they clear it, call us and we will inspect the furnace, the gas connections and the heat exchanger.

How soon can you get to my house in Duncanville?

Call us with your address and a short description of the problem and we will give you the next open window, usually same day or next day depending on how the heat is running that week. No cooling at all and homes with older residents or infants move up the list.

How it works

Step 1
Tell us the symptom
Call or fill in the quote form with what you hear, smell or feel. Warm air, short cycling, a breaker that keeps tripping. Details on your porch help us arrive with the right parts.
Step 2
We diagnose on site
A technician checks the thermostat, airflow, the indoor coil and blower, then the outdoor unit and electrical side. You get a plain explanation of what failed and why it failed.
Step 3
You approve the repair
We walk you through the fix and any parts involved before we start. Once you say go, we make the repair and confirm the system is holding temperature before we leave your driveway.

Why homeowners call us

Built for hard summersWe work on attic air handlers in July heat, undersized returns in older subdivisions, and condensers with hail-flattened fins. Those are everyday jobs across the region, so we know where these systems tend to give out first.
Air conditioner repair and heating repairOne crew for both seasons. Air conditioning repair when the house won't cool, heater repair and furnace repair when the burners won't stay lit. Same technicians, same records, so nobody starts from scratch in November.
We explain the failureYou hear which component failed and what it was doing to the rest of the system. If a repair is a short-term patch on an aging unit, we say so and let you decide the timing.
Respect for the houseDrop cloths, shoe covers, and the attic hatch closed the way we found it. We keep the work area clean and we tell you honestly when a problem is airflow or ductwork rather than the equipment itself.
All major brands, gas & electricOne independent crew for Carrier, Trane, Lennox, Goodman, Rheem and more.
Straight answersIf a system is not worth repairing, we say so, often right on the phone.
