Common heater problems we fix in Plano:
Comprehensive heating repair for every system and every problem.
24/7 emergency response for heater failures. We diagnose and repair pilot light issues, igniter failures, blower problems, and thermostat malfunctions. When your furnace quits on the coldest night, we're there in 15-25 minutes.
Expert repair for heat pumps that won't heat, ice over, or constantly cycle. We handle refrigerant issues, reversing valve failures, defrost control problems, and compressor diagnostics specific to Plano's climate.
We repair and replace thermostats that won't reach set temperature, display incorrect readings, or lose WiFi connection. From mechanical Honeywell models to smart Ecobee and Nest systems.
Specialized repair for flame sensors, gas valves, pressure switches, limit switches, and inducer motors. We diagnose ignition failures, resolve venting issues, and restore safe furnace operation.
We repair and replace furnace blower motors, capacitors, and fan assemblies that cause weak airflow or noisy operation. Whether your system won't blow air at all or sounds like a freight train, we fix it.
Comprehensive safety inspections check for carbon monoxide leaks, cracked heat exchangers, faulty pressure switches, and improper venting. We test every safety control before small issues become dangerous.
Don't wait until your furnace fails completely—call at the first warning sign.
If your furnace runs but doesn't produce heat, or if some rooms stay cold while others warm up, you likely have igniter failure, a faulty gas valve, or ductwork issues. This requires immediate diagnosis.
Banging, squealing, rattling, or grinding noises signal blower motor problems, loose panels, belt issues, or failing bearings. Ignoring these sounds leads to complete system failure.
Short-cycling wastes energy, wears out components, and indicates thermostat problems, flame sensor issues, or airflow restrictions. This problem only gets worse with time.
If your pilot light repeatedly goes out, you may have thermocouple failure, gas supply problems, or dangerous venting issues. Never ignore pilot light problems—they're a safety concern.
A sudden spike in winter heating costs indicates your furnace is working harder than it should. This often means restricted airflow, failing components, or efficiency losses.
A yellow or flickering pilot light (instead of bright blue) or soot around the furnace indicates incomplete combustion and possible carbon monoxide production. Call immediately.

"Our furnace died at 11 PM when it was 32 degrees outside. I called LEX and they actually showed up in 20 minutes. The technician diagnosed a bad igniter, had the part on his truck, and had us back up and running by midnight. Being headquartered right here in Plano really makes a difference."— Jennifer M., West Plano

Generally, if your system is under 10 years old and the repair costs less than 50% of replacement, repair makes sense. If your furnace is 15+ years old and needs a major repair (heat exchanger, blower motor, gas valve), replacement is usually more cost-effective. We'll give you honest advice.
The most common causes in Plano homes are: failed igniters (40% of failures), dirty flame sensors (25%), thermostat issues (15%), blower motor failures (10%), and gas valve problems (10%). Most of these are repairable if caught early.
Most heater repairs take 1-2 hours once our technician arrives. Simple fixes (igniter, flame sensor, thermostat) take 30-60 minutes. More complex repairs (blower motor, gas valve) take 1-3 hours. If we need a special part, we'll return to complete the repair once it arrives.
Yes, potentially. A yellow or flickering pilot light (instead of bright blue) indicates incomplete combustion, which can produce carbon monoxide. If you see a yellow flame, turn off your furnace and call LEX immediately. Never attempt to adjust it yourself.
