Garland’s housing stock matters here. These aren’t new builds with tight ductwork and modern returns. They’re 1960s, 70s, and 80s slab-on-grade homes with original galvanized ducting, undersized returns, and gas furnaces that have been patched together for decades. Our Furnace Repair team works on these systems every single week, and we bring that experience to every call we run in Garland.

Styles & brands we work with




Boiler Repair in Garland
Boiler Repair in Garland shows up most often in the older ranch homes around Duck Creek and the neighborhoods north of Downtown Garland, where hydronic heat was installed in the 1960s and 1970s and then run hard for fifty years. The job usually means a failing circulator pump, a stuck zone valve, an air-bound loop, or a pressure issue at the expansion tank. Most boiler repairs in Garland land between $300 and $700, depending on the component. A stuck zone valve or air purge is on the lower end. A circulator pump replacement or expansion tank swap runs higher.
Common Boiler Issues in Garland’s Older Homes
Original cast-iron loops with no accessible crawlspace or basement mean air bleeds and pressure checks are done at the radiators and the boiler itself, not from underneath. That’s slower, more deliberate work, and we plan for it. Garland’s hard water also leaves mineral deposits in zone valves, which seize after two or three decades of service.
What a Boiler Repair Call Includes
We verify system pressure, bleed air from the loop, test the aquastat, and check the expansion tank before replacing any part. The price is in writing before we open the boiler. If the same zone fails again within the year, the return visit is free, with our written guarantee on every repair.
Gas Furnace Repair in Garland
Gas Furnace Repair in Garland is what we run most between November and February, when the first real cold snap hits and furnaces that sat untouched since March refuse to light. The work typically means a failed ignitor, a bad flame sensor, a blower motor that’s seized or dragging, or a gas valve that won’t open. Most gas furnace repairs in Garland run $150 – $500. An ignitor or flame sensor is a $150 – $250 job. A blower motor or gas valve replacement pushes toward $500 – $700.
Why Garland Gas Furnaces Fail on the First Cold Snap
Garland’s heating season is short, and homeowners defer maintenance because the furnace was “fine all summer.” What happens instead is the blower motor bearings dry out, the capacitor degrades, and the flame sensor picks up a carbon film. Six months of neglect, then a hard start. The first 30°F night of the year is when we see the backlog of calls.
What We Check Before Replacing Anything
We test the ignitor, clean and test the flame sensor, inspect the heat exchanger for cracks or burn-through, check gas pressure at the valve, and run a static pressure test on the ductwork before we close out the job. In Garland’s older homes, the furnace failure is often the symptom, not the cause. The cause is undersized returns and leaking galvanized duct that starved the system for decades.
Trusted Brands We Service in Garland
We service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard furnaces, and our techs are factory-trained on all nine. For Garland customers, we keep common parts stocked locally: ignitors, flame sensors, capacitors, blower motors, gas valves, and pressure switches. That means when we diagnose a failed Trane ignitor in a 1980s two-story off Naaman School Road, we’re not sending you back to a cold house while we order a part from Dallas. Most repairs are completed same-day from the truck stock.

AfterCommon Furnace Repair Problems We See in Garland Homes
- Tripped limit switches from starving returns. Original undersized return ducts in 1960s and 1970s slab homes starve the blower of air. The furnace overheats, trips the limit, and cycles off. Often misdiagnosed as a bad thermostat or a bad board. We test static pressure before condemning any part.
- Cracked heat exchangers from long, hard runs. Single-pane windows and uninsulated slab floors make a Garland furnace run long cycles every winter. That heat soaks the exchanger until it stress-cracks. We inspect the exchanger on every repair call where the system is over 15 years old, because a cracked exchanger on an 80% furnace is a carbon monoxide risk, not just a comfort issue.
- Cottonwood and oak pollen clogging burners and coils. Garland’s spring pollen load is brutal on outdoor units and finds its way into furnace cabinets too. Matted cottonwood on a burner assembly causes poor flame and delayed ignition. We see it constantly in older neighborhoods with mature trees.
- Failed capacitors from power surges and age. Garland gets real heat, real storms, and real voltage fluctuation. Capacitors on blower motors and inducer motors degrade and fail, often taking the motor with them if ignored. We check capacitor microfarad readings on every repair, not just when the motor is already dead.

FAQs About Furnace Repair in Garland
The most common cause in Garland is undersized or leaking return ductwork in an older slab-on-grade home. When the return ducts are too small, the blower can’t move enough air across the heat exchanger, the furnace overheats, and the limit switch trips as a safety lockout. We run a static pressure test on the duct system to confirm it before we replace any part. If the limit switch itself is weak, that’s a simple fix, but if the ducts are the problem, a new switch won’t stop the tripping. Call (254) 280-5320 and we’ll diagnose the actual cause, not the symptom.
If the furnace is from the 1970s, it’s an 80% AFUE unit at best and likely well past its rated service life. We’ll repair it if the failure is a $150 – $300 part and the heat exchanger is sound. But if the heat exchanger is cracked, the repair cost approaches the price of a new furnace, and we’ll tell you that clearly. We give you a written price for both options and let you decide. No pressure. Call (254) 280-5320 for a straight answer.
Not necessarily. If your AC is a newer R-410A system or a unit in good shape, you can replace the furnace alone with a coil that matches your existing outdoor unit. In Garland’s older homes, though, many ACs are R-22 systems that are near the end of their life. If that’s your situation, replacing both at once saves you a second labor bill and lets us match the indoor coil to the new outdoor unit properly. We’ll show you the separate and combined prices so you can make the call.
That smell is dust burning off the heat exchanger after sitting all summer. It’s common in Garland homes because the cooling season runs long and the furnace sits dormant from April through October. The smell should clear within 20 to 30 minutes of the first burn. If it continues for hours, or if it smells like gas or burning plastic, shut the system down and call (254) 280-5320 right away. A lingering acrid smell can indicate a cracked heat exchanger or an overheating blower motor.
Most furnace repairs in Garland run $150 – $700. A flame sensor or ignitor replacement is $150 – $250, and a blower motor, inducer motor, or gas valve is $400 – $700. The price is in writing before we begin, and every repair carries a full-year written guarantee. If the work doesn’t hold, we return at no charge. Call (254) 280-5320 for a free estimate on your specific furnace.
