Signs You Need Heater Repair in Frisco

Don't wait until you're freezing — these warning signs mean it's time to call LEX for professional heater repair.

Heater Won't Turn On

If your furnace or heater won't start at all, you may have a thermostat problem, electrical issue, pilot light failure, or gas valve malfunction. This requires immediate professional diagnosis.

Blowing Cold Air

A heater blowing cold air usually indicates a pilot light issue, faulty gas valve, broken heating element, or thermostat misconfiguration. This is one of the most common calls we get in Frisco.

Strange Noises

Banging, rattling, screeching, or grinding sounds from your furnace indicate mechanical problems like blower motor failure, loose components, or ignition issues that need immediate attention.

High Energy Bills

A sudden spike in your heating bills often means your system is running inefficiently due to dirty filters, ductwork leaks, or failing components. We can diagnose and restore efficiency.

Short Cycling

If your heater turns on and off repeatedly without reaching the set temperature, you may have a bad thermostat, clogged filter, or airflow problem requiring professional repair.

Yellow Pilot Light or Gas Smell

A yellow (instead of blue) pilot light or any smell of gas indicates a dangerous carbon monoxide or gas leak situation. Turn off your heater immediately and call LEX for emergency service.

"Our heater went out on a Sunday night when it was freezing. LEX sent a technician to our Starwood home within 30 minutes. He diagnosed the problem quickly, explained everything clearly, and had us warm again in under an hour. Pricing was fair and upfront. These guys are the real deal."
