When your furnace quits during a Richardson cold snap, you need a straight answer: what’s wrong, what it costs, and who’s walking through your door. Most furnace repairs in Richardson run between $150 and $700, and our crews reach most Richardson neighborhoods within hours, not days. Call (325) 312-3269 and you’ll talk to a live person who can schedule a technician in Richardson today.
We know Richardson’s housing stock because we work in it every week. Homes here, especially the 1960s and 70s brick-veneer tracts and the 1980s and 90s custom builds, don’t fail the way newer construction does. An older furnace in Richardson usually isn’t just “broken.” It’s usually fighting a duct system that was sized for a different era, or an electrical panel that predates the modern blower motors. That’s the repair most companies miss. We don’t.

Heating Repair in Richardson
Heating repair in Richardson is the work of diagnosing and fixing whatever keeps your furnace from producing or distributing warm air, whether that’s a failed ignitor, a cracked heat exchanger, a seized blower motor, or a gas valve that won’t open. In Richardson, we see a particular pattern: original furnaces in 1960s and 70s tract homes in neighborhoods like Reservation and Springpark that were installed when natural gas was cheap and insulation was an afterthought. Those systems were often oversized for the home’s actual heat load, and today they short-cycle and wear out components faster than they should.
Most heating repairs in Richardson fall in the $150 – $700 range. An ignitor replacement typically runs $150 – $300 parts and labor included. A blower motor repair lands between $350 and $700 depending on whether it’s a single-speed PSC motor or an ECM variable-speed unit. Gas valve replacement usually runs $300 – $500. Before any work begins, you’ll have a written price in your hand. If the repair doesn’t hold within the guarantee period, we return free of charge.
Gas Valve and Ignitor Work
When your furnace won’t fire or a burner won’t stay lit in Richardson, the culprit is usually the gas valve or the hot surface ignitor. Ignitors are a consumable part. They crack and fail after years of thermal cycling. Our techs carry common ignitors and gas valves on their trucks for Bryant, American Standard, Carrier, and Trane, so many Richardson repairs happen on the first visit.
Blower and Airflow Repairs
Blower motors fail more often in Richardson homes with undersized return ducts. The motor works harder than it was designed to, pulling high amps until the windings overheat. In the Reservation neighborhood, we have seen 1970s-era returns that are a third smaller than what a modern furnace needs. Replacing the motor without addressing the airflow problem means replacing it again in a few years. We’ll tell you that before we sell you a motor.
Boiler Repair in Richardson
Boiler repair in Richardson is less common than furnace repair, but there are older neighborhoods here where boilers still heat homes built in the 1960s and earlier. These systems use hot water circulated through radiators or baseboard units. When a boiler in Richardson fails, it’s usually a circulator pump, a pressure relief valve, an expansion tank, or a zone valve. Less frequently, it’s a heat exchanger issue that requires careful evaluation against the cost of replacement.
Boiler repairs in Richardson typically run $150 – $700, with most common fixes like circulator pump replacement landing in the $350 – $600 range depending on the pump model. Zone valve work usually falls between $250 and $450. Expansion tank replacement is often $200 – $350. Because boiler systems are less common in Texas than in northern climates, some contractors treat them as an afterthought. We don’t. Our technicians who handle boiler work in Richardson have specific training in hydronic systems, and they know how to diagnose a pressure problem from a purge problem without guessing.
Circulator and Zone Valve Service
If some rooms in your Richardson home heat while others stay cold, the likely cause is a failed zone valve or circulator. These parts wear out on a schedule, especially in systems that run hard during the few genuinely cold weeks Richardson gets. We diagnose the specific valve or pump before quoting a repair, so you’re not paying for parts you don’t need.
Pressure and Expansion Repairs
Boilers in Richardson that lose pressure repeatedly or vent water from the relief valve usually have a failed expansion tank. This is a straightforward repair, but it needs to be diagnosed properly. An expansion tank that’s waterlogged will cause pressure spikes that can damage the heat exchanger over time. We check the pressure, test the tank, and give you a written quote on the spot.
Trusted Brands We Service in Richardson
We service furnaces and boilers from all major brands in Richardson, and we stock common ignitors, flame sensors, pressure switches, and gas valves locally for Bryant, American Standard, Carrier, and Trane systems. That means faster turnaround for Richardson customers who’d rather not wait on a shipped part when the house is cold. Your furnace brand matters less than the quality of the diagnosis. A 1989 Carrier that’s been properly maintained will often outlast a 2015 builder-grade unit that hasn’t. We’ll tell you the truth about what your specific system needs here in Richardson.
Common Furnace Repair Problems We See in Richardson Homes
- High-limit switch trips from restricted airflow. Richardson’s 1960s and 70s tract homes often have duct systems that were marginal when new and are now decades past their design life. A furnace that trips the high-limit switch repeatedly is usually telling you the airflow is restricted, not that the switch itself is bad. Swapping the switch without fixing the airflow brings repeat failures.
- Cracked heat exchangers in original units. Furnaces from the 1970s and 80s in Richardson homes are near the end of their design life. Metal fatigue from decades of thermal expansion causes hairline cracks. These cracks release carbon monoxide. A cracked heat exchanger is a safety issue, not a repair project. We’ll show you the crack and explain your replacement options.
- ECM blower motor failures after storms. Power surges during Richardson’s spring and fall thunderstorms can damage the control modules on variable-speed blower motors. If your furnace blower runs erratically or won’t start after a storm, the module may have taken a surge. We see this regularly in Richardson homes across the Telecom Corridor during storm season.
- Ignitor failures on cold starts. The first hard freeze of the season is when we get the most ignitor calls in Richardson. Silicon nitride and carbide ignitors wear out from repeated heat cycles, and they have no warning signs. They just fail. We keep common ignitors stocked on our trucks for fast same-day repair in Richardson.

Why a Like-for-Like Swap Often Disappoints in an Older Richardson Home
Richardson’s housing stock is a mix of 1960s and 70s tract homes and 1980s and 90s custom builds. That mix creates a specific repair and replacement challenge you won’t hear about from a generic HVAC company. Many original furnaces in these homes are being replaced for the first time. The instinct is to put in a new furnace of the same BTU rating and call it done. Here’s the problem: the old furnace was probably oversized when it was installed, and it’s been running on ductwork that was undersized from day one. Put a modern high-efficiency furnace on that same duct system and you get short-cycling, uneven room temperatures, and a blower motor that fails early because it’s fighting static pressure it wasn’t designed to handle.
We learned this lesson in a specific home in the Reservation neighborhood. A 1972 original unit kept tripping the limit switch, and the homeowner had already replaced the filter twice. Our techs found a clogged evaporator coil, a blower motor pulling high amps, and return ducts that were a third smaller than what the furnace needed. After cleaning the coil and rebalancing the airflow, the furnace ran within spec without replacing the heat exchanger. A less thorough company would have sold a new furnace and left the real problem in the attic.
Before we recommend a furnace replacement in Richardson, we measure static pressure, check the return and supply sizing, and do a proper load calculation. If the ducts need work, we tell you. If the electrical panel can’t handle a modern ECM blower motor, we tell you that too. That’s the difference between a furnace that lasts 20 years and one that limps along for eight.

FAQs About Furnace Repair in Richardson
Because the high-limit switch is doing its job. It’s shutting the furnace down to prevent overheating. In a 1980s-era Richardson furnace, the usual cause is restricted airflow, not the switch itself. You may have undersized return ducts, a blower motor that’s worn and moving less air than it should, or a heat exchanger that’s partially blocked. Swapping the limit switch without fixing the airflow problem is a temporary bandage. Our techs measure static pressure and airflow before recommending a fix, so you’re not paying for a switch that trips again next month. Call (325) 312-3269 and we’ll diagnose it properly.
You can sometimes keep the existing coil if it’s compatible with the new furnace’s refrigerant and capacity, but it often isn’t. Many Creek Hollow homes still run on R-22 systems that are being phased out. If the coil is in good shape and matches the new furnace’s capacity, it may work for a while. But if the coil is old, rusty, or the wrong size for the new system, keeping it will hurt efficiency and can shorten the new furnace’s life. We’ll inspect the coil and give you an honest recommendation. The goal is a system that works together, not a mix of parts from different decades.
First, check your breaker panel. Richardson’s spring and fall storms bring power surges that can trip breakers or damage furnace control boards. Reset the breaker once. If the furnace still won’t start, don’t keep cycling the power. A surge may have damaged the control board or the blower motor module, and repeated resets can make the damage worse. Call us at (325) 312-3269. We’ll send a Richardson technician to test the board, the ignitor, and the motor, and we’ll tell you exactly what failed before we fix it.
Every year. No exceptions. A 50-year-old furnace in a 1970s Richardson tract home has been through thousands of heat cycles, and the parts that fail are the ones you can’t see: heat exchanger welds, gas valve diaphragms, and blower motor bearings. An annual tune-up in Richardson runs $80 – $200, and it’s the difference between catching a cracked heat exchanger in October and finding out about it in February. We check combustion, gas pressure, airflow, and safety limits, and we give you a written report of what we found. You’ll know what’s wearing out before it fails.
You need a load calculation. Matching the old unit’s tonnage is exactly the mistake that causes problems in Richardson homes. The original furnace was probably oversized when it was installed 40 years ago. If you replace it with the same capacity, you get a furnace that heats the house too fast, short-cycles, and leaves rooms uneven because the single-zone layout wasn’t designed for modern equipment. A load calculation uses your home’s actual insulation, window area, orientation, and duct condition to size the furnace correctly. We do load calculations on every replacement we quote in Richardson. The result is a furnace that runs longer, heats more evenly, and costs less to operate.
