When a furnace gives out during a Dallas cold snap, you need someone who answers the phone and shows up when they say they will. We’ve been repairing furnaces across Dallas since 2003, and most calls get a same-day visit from a background-checked, uniformed technician who knows Trane, Lennox, Goodman, and Rheem systems inside and out. Victor Mancini leads our Dallas team, and every repair we do comes with a written 365-Day Done Right Promise: if your repair fails inside a year, we return and fix it at no charge. Call (430) 213-5796 any time, day or night. A live person picks up.
Furnace Maintenance
Furnace Maintenance is the scheduled upkeep that keeps your heating system from breaking down in the first place. In Dallas, we recommend a full furnace maintenance visit every fall, before the first cold front pushes through places like Lakewood, Preston Hollow, and Oak Lawn. If your system does break down, we also offer Furnace Repair in Dallas. A technician inspects the heat exchanger for cracks, checks gas pressure, cleans the burners, tests the safety controls, and replaces the air filter if needed. Maintenance runs $80 – $200 depending on the age and condition of the unit, and it catches small problems before they become $700 repair jobs on a 30-degree night. The Kingswell Way applies here too: you get a written report of exactly what was checked and found.
Fall Tune-Up Checks
Our fall maintenance visit includes a combustion analysis to confirm your furnace burns cleanly and safely. We also test the igniter, flame sensor, and limit switches, which are the three parts most likely to fail on a Bryant or American Standard furnace in Dallas.
Mid-Season Filter Service
A clogged filter is the single most common cause of avoidable furnace problems in Dallas homes. We show you how to check it and what MERV rating works best for your system, whether you have a standard 1-inch filter or a thicker media cabinet.
Styles & brands we work with
Heat Pump Repair
Heat Pump Repair covers the outdoor condenser and indoor air handler that keep Dallas homes warm in winter by reversing the flow of refrigerant. Since a heat pump runs year-round, in Dallas it works twice as hard as a furnace-only system, and wear shows up faster. If your heat pump is blowing lukewarm air, icing over, or short-cycling, call us at (430) 213-5796. Repairs typically run $150 – $700, and our technicians carry reversing valves, defrost boards, capacitors, and contactors on the truck so most fixes happen in one visit.
Defrost and Icing Problems
Heat pumps in Dallas rarely deal with heavy snow, but high humidity in places like Carrollton and Farmers Branch can cause the outdoor coil to frost over. For heating issues in Carrollton specifically, see our Furnace Repair in Carrollton. When the defrost cycle fails, the unit runs inefficiently and can damage the compressor, so we check defrost sensors and control boards on every heat pump call.
Reversing Valve Service
The reversing valve is what lets a heat pump switch between cooling and heating. When it sticks, your system might cool when you need heat, or vice versa. We test the solenoid and valve body, and if it’s failed, we quote a written price before replacing it.
Heating Repair
Heating Repair is the broad term for fixing any part of your home’s heating system, whether it’s a gas furnace, an electric air handler, or a dual-fuel setup with a heat pump. Most Dallas heating calls we get involve a system that won’t start, won’t stay running, or doesn’t heat evenly through the house. Costs depend on the part, with typical heating repairs falling between $150 and $700. Before any tool comes out, you get a written price in your hand. That’s the Kingswell Way: no surprises at the door, and a guarantee on paper when we leave.
Ignition and Starting Failures
When a Dallas furnace won’t fire up, the cause is usually an igniter, flame sensor, or gas valve. We test each component in sequence rather than swapping parts blindly, which saves you money and gets the heat back on faster.
Short Cycling Issues
A furnace that turns on and off every few minutes wastes gas and wears out parts prematurely. In Dallas homes we often trace short cycling to an overheating heat exchanger, a dirty flame sensor, or a thermostat that’s wired incorrectly.
Boiler Repair
Boiler Repair addresses the hydronic heating systems found in some older Dallas homes, particularly in Highland Park, Lakewood, and parts of Oak Lawn. Boilers circulate hot water through radiators or baseboard units instead of pushing warm air through ducts. When a boiler loses pressure, develops a leak, or the circulator pump fails, you’ll notice cold spots in rooms or a system that runs constantly without delivering consistent heat. Repairs typically run $150 – $700, and our technicians test expansion tanks, pressure relief valves, and aquastats on every boiler visit in Dallas.
Circulator Pump Failure
The circulator pump moves hot water from the boiler to your radiators. When it fails, the boiler itself may still fire, but heat never reaches the rooms. We check the pump’s impeller and capacitor first, which is often a fast fix.
Pressure and Leak Diagnosis
A boiler that loses pressure constantly usually has a leak somewhere in the loop, and in Dallas’s older bungalows that’s often an aging pipe fitting or a failing pressure relief valve. We locate the leak and quote a written price before any repair work begins.
Gas Furnace Repair
Gas Furnace Repair focuses on the most common heating system in Dallas: a natural gas furnace with a burner assembly, heat exchanger, and blower motor. Because these systems involve an open flame and combustion gases, safety is the first thing we check. A cracked heat exchanger can leak carbon monoxide into your home, which is why every gas furnace repair in Dallas includes a combustion safety inspection. Typical gas furnace repairs run $150 – $700, and we service Goodman, Trane, Lennox, Rheem, and every other major brand. Call (430) 213-5796 for a free estimate.
Burner and Flame Sensor Cleaning
A dirty flame sensor is the most common reason a gas furnace in Dallas lights and then shuts off seconds later. Cleaning the sensor is a quick job, but if it’s worn, we replace it with an OEM part and cover the work under our 365-day guarantee.
Gas Valve and Pressure Testing
If your furnace isn’t getting enough gas or the valve won’t open, the system either underheats or won’t start at all. We test inlet and outlet gas pressures with a manometer and verify the valve operates within manufacturer specs before adjusting or replacing anything. Working on gas lines is dangerous. If you smell gas, leave the house and call the utility company first, then call us once the line is cleared.
Furnace Tune Up
Furnace Tune Up is a preventive service that costs $80 – $200 and is the cheapest insurance against a no-heat call in the middle of a Dallas cold front. During a tune up, we clean the burners, test the igniter, check the heat exchanger for cracks, verify carbon monoxide levels, measure the temperature rise across the system, and calibrate the thermostat. A furnace that’s been tuned runs more efficiently, which means lower gas bills in neighborhoods like Addison and Sachse where winter temps can dip into the 20s. For repairs in Addison, we offer our Furnace Repair in Addison. You get a written report when we leave, and a reminder each fall if you want us back.
What Gets Checked
We inspect every major component from the flame sensor to the blower motor. We also test the capacitor and measure the amp draw on the blower, since a failing capacitor is a common cause of mid-winter breakdowns in Dallas.
Why Annual Tune-Ups Matter
Furnace manufacturers require annual maintenance to keep warranties valid. A skipped tune-up can void a warranty on a two-year-old Trane or Goodman furnace, and that’s an unnecessary risk for a Dallas homeowner.
Emergency Furnace Repair
Emergency Furnace Repair is what we do when the heat goes out after hours and you need someone now, not tomorrow morning. Dallas winters may be short, but a house without heat in February is uncomfortable and sometimes unsafe, especially for kids, elderly family members, or anyone with a respiratory condition. Our phone line is answered by a live person 24 hours a day, 7 days a week, including holidays. Emergency furnace repair in Dallas runs the same $150 – $700 range as our standard repairs, with no after-hours surcharge and no overtime fee. You get a firm arrival window and a written price before work begins, even at 2 a.m.
What Counts as an Emergency
No heat on a freezing night, a gas smell, or a furnace making a loud banging or screeching sound are all reasons to call immediately. If you smell gas, leave the house first and call the gas company, then call us once you’re safe and the line has been checked.
What to Expect When You Call
A live dispatcher answers and asks about your system and symptoms. They’ll give you a firm window for the technician’s arrival, and the technician calls when they’re en route. The written price applies no matter what time of day or night the call comes in.
Brands We Service
Our Dallas technicians are factory-trained on Trane and Lennox systems, two brands we see constantly in houses across North Dallas and Richardson. We keep their common parts on the truck: igniters, flame sensors, pressure switches, and control boards, so a Trane or Lennox repair usually gets done in one visit rather than waiting on a parts house run.
We work on Goodman and Rheem furnaces just as often, especially in newer construction around Coppell, DeSoto, and Farmers Branch. We also provide Furnace Repair - Irving for homes in that area. Goodman and Rheem are solid systems, but their igniters and limit switches wear faster than premium brands. Whether you have a Goodman, a Rheem, or any other make, we can help, and every repair is covered in writing for 365 days.

AfterSigns You Need a Pro Right Now
- Your furnace is blowing cold air. This usually means the burners aren’t staying lit or the gas valve isn’t opening. It’s not a filter problem you can fix yourself, and running the blower without heat wastes electricity while your house gets colder.
- You smell gas or a burning odor. A gas smell means leave the house immediately and call the utility. A burning dust smell on the first start of the season is usually harmless and clears in an hour, but a persistent electrical or acrid smell needs a professional check before you run the system again.
- Your furnace is making loud banging or screeching noises. Banging can mean a delayed ignition or a cracked heat exchanger. Screeching points to a failing blower motor or a loose belt. Both get worse the longer you ignore them, and the repair bill climbs accordingly.
- Rooms are heating unevenly. If the living room is warm but the bedroom never gets there, you might have a duct problem, a failing blower motor, or a zoning issue. A technician can diagnose it quickly, and the fix is often simpler than you’d expect.
- Your gas bill spiked with no obvious reason. A furnace running inefficiently burns more gas to deliver the same heat. A failing component, clogged filter, or dirty burner can all cause a spike, and a tune-up usually finds the cause fast.
Our Process, Step by Step
- 1
You call and a live person answers. No voicemail, no phone tree, no waiting until morning. We take your information, ask about the symptoms, and schedule a technician with a firm arrival window.

We diagnose and hand you a written price. Using a digital multimeter, manometer, and combustion analyzer, the technician finds the actual cause of the failure. Then you get a written price with parts and labor separated, before any work begins.
- 4
We make the repair and test the system. The fix gets done with OEM or factory-approved parts, then we run the furnace through a full cycle and test for carbon monoxide, gas leaks, and proper airflow.
- 5
You get a written guarantee before we leave. Every repair comes with our 365-Day Done Right Promise on paper. If the same repair fails within a year, we come back and make it right at no charge. And we leave your utility closet cleaner than we found it.
How Much Does Furnace Repair Cost in Dallas?
Furnace repair in Dallas typically runs between $150 and $700, depending on the part that failed and the age of your system. A simple igniter replacement on a Goodman or Rheem furnace usually lands in the $150 – $280 range, parts and labor included. A blower motor replacement runs higher, often $400 – $700. A cracked heat exchanger, which requires either a heat exchanger replacement or a new furnace, is the most costly repair you’ll encounter, and it’s one we always document with photos so you can see exactly what we found.
What moves the price? The part itself, how accessible your furnace is, and whether the system is still under warranty. A Trane or Lennox furnace inside its parts warranty window saves you hundreds on components. The cheapest option isn’t always the best; a $120 repair with a 30-day guarantee usually costs more in the long run than a $200 repair backed for 365 days. Our free estimates are real estimates: we show up, diagnose the problem, and hand you a written price with no obligation. If you decide not to go ahead, you owe us nothing.
