Richardson's diverse housing stock—from established neighborhoods like Canyon Creek and Northrich to the apartments near UTD—means a wide variety of heating systems that all need professional care. Whether you're in a 1970s brick home with an aging gas furnace or a newer construction in Spring Valley with a modern heat pump, our technicians know how to diagnose and repair every type of heater. Richardson winters may be mild compared to up north, but when overnight temperatures drop into the 20s and 30s, a broken furnace isn't just uncomfortable—it can lead to frozen pipes and dangerous carbon monoxide situations.
Based just 15-20 minutes away in Plano, LEX Air Conditioning has been Richardson's go-to furnace repair company since 2004. Our proximity means we can respond fast to heater emergencies—often arriving the same day you call.

Our Richardson heater repair services cover everything from pilot light relighting and thermostat troubleshooting to blower motor replacement and heat exchanger repairs. We repair gas furnaces, electric furnaces, heat pumps, dual-fuel systems, and hybrid heating setups.

And if your furnace is beyond economical repair, we offer transparent recommendations for heater installation with financing options and manufacturer rebates. Whether you need a quick fix or a full system replacement, LEX delivers honest service at fair prices—no bait-and-switch pricing, no pressure tactics, just reliable heating solutions for your Richardson home.

Learn MoreDon't wait until your furnace dies completely—these warning signs mean it's time to call LEX for professional heater repair:
If your furnace runs but only blows cold air, you likely have a pilot light failure, igniter problem, or gas valve issue. Never ignore this—call for same-day diagnosis before temperatures drop overnight.
DANGER: A pilot light should burn steady blue. Yellow or flickering flames indicate incomplete combustion and potential carbon monoxide production. Turn off your furnace and call immediately—this is a safety emergency.
Banging can indicate delayed ignition (dangerous gas buildup), screeching often means a worn blower motor belt, and rumbling suggests burner problems. Any unusual sounds warrant professional inspection—don't wait until it fails completely.
Short-cycling wastes energy, stresses components, and leaves your Richardson home unevenly heated. Causes range from dirty filters and thermostat issues to serious problems like a cracked heat exchanger. We'll diagnose the root cause fast.
If your heating bills spike but usage hasn't changed, your furnace is working harder than it should. This often means failing components, ductwork leaks, or a system nearing end-of-life. A professional tune-up can restore efficiency and save money.
DANGER: Natural gas smells (rotten egg odor) require immediate evacuation and a call to 911, then us. Burning smells on first startup are normal, but persistent burning or musty odors indicate dust buildup, electrical issues, or mold—all requiring professional attention.
"Our furnace quit on a Saturday morning when it was 28 degrees outside. LEX had a technician at our Canyon Creek home in 20 minutes. He diagnosed a bad igniter, had the part on his truck, and had us warm again in under an hour. Upfront pricing, no pressure, just honest service. I've already recommended them to three neighbors."

We typically arrive within 15-20 minutes of your call. LEX is based in Plano, just a short drive from Richardson via Highway 75 or Arapaho Road, which means we can respond faster than companies based in Dallas or Fort Worth.

Most heater repairs range from $150 to $600 depending on the issue. Simple fixes like thermostat replacement or pilot light service run $150-$250, while component replacements (igniter, blower motor, gas valve) typically cost $300-$600. We provide upfront, written estimates before starting any work—no surprises, no hidden fees. If your furnace needs major repairs (heat exchanger, full control board), we'll give you honest guidance on whether repair or replacement makes more financial sense.
Common causes include: a pilot light that's out (older furnaces), a failed igniter (newer furnaces), a malfunctioning gas valve, a tripped limit switch, or thermostat wiring issues. Sometimes it's as simple as the thermostat being set to "fan on" instead of "auto." Our technicians will diagnose the exact cause and explain your options clearly—most cold-air issues can be fixed in one visit.
Yes—this is a safety emergency. A healthy pilot light burns steady blue. Yellow, orange, or flickering flames indicate incomplete combustion, which produces carbon monoxide (a deadly, odorless gas). If you see a yellow pilot light, turn off your furnace immediately, open windows, leave the home if anyone feels dizzy or nauseous, and call us for emergency service. We'll inspect the burner assembly, heat exchanger, and ventilation to ensure safe operation before relighting.
Annual furnace maintenance is recommended every fall before heating season begins (ideally September or October in North Texas). Regular tune-ups catch small issues before they become expensive repairs, improve efficiency (lowering energy bills), extend equipment life, and ensure safe operation. During a tune-up, we inspect the heat exchanger for cracks, test the igniter and flame sensor, check gas pressure, clean burners, lubricate the blower motor, and verify carbon monoxide levels are safe.
Yes. Our technicians are trained and certified to repair all major furnace brands including Carrier, Trane, Lennox, Rheem, Ruud, Goodman, Amana, York, Coleman, and more. We stock common replacement parts on our trucks (igniters, flame sensors, capacitors, thermostats) and have access to next-day delivery for less common components. Whether your furnace is 5 or 25 years old, we can diagnose and repair it.
