Learn MoreDon't wait until your heater stops working completely. These warning signs indicate it's time to call LEX for professional heater repair:
If your heater doesn't respond when you adjust the thermostat, you may have igniter failure, a dead thermostat, tripped breaker, or pilot light issues. This requires immediate diagnosis to restore heat to your Carrollton home.
Banging, squealing, grinding, or rattling noises indicate mechanical problems. Worn blower bearings, loose belts, cracked heat exchangers, or ductwork issues need professional attention before causing complete system failure.
Little or no air coming from vents suggests blower motor failure, clogged filters, or ductwork problems. Weak airflow reduces heating efficiency and increases energy costs in your Carrollton home.
Some rooms too hot while others stay cold? This indicates thermostat problems, ductwork leaks, or zone control issues. Uneven heating wastes energy and reduces comfort throughout your home.
Sudden increases in heating costs without increased usage indicate inefficient operation. Worn components, dirty burners, or airflow restrictions force your heater to work harder, wasting money on energy bills.
Natural gas odors require immediate evacuation and emergency service. Burning smells may indicate overheating, electrical issues, or dust buildup. Both situations need professional inspection to ensure your safety.
