If your heater doesn't respond when you turn up the thermostat, it could be a tripped breaker, pilot light issue, ignition failure, or thermostat malfunction. This requires immediate professional diagnosis.
Poor airflow means your furnace is running but not heating effectively. Common causes include blower motor failure, clogged filters, ductwork issues, or a failing capacitor.
Banging, rattling, screeching, or rumbling sounds from your furnace indicate mechanical problems—loose parts, worn belts, or motor bearings that need immediate attention before causing more damage.
If you smell natural gas (rotten egg odor) near your furnace, shut off gas at the meter, evacuate your home, and call 911, then call LEX. This is a serious safety hazard requiring emergency response.
Short cycling—when your furnace turns on and off repeatedly without completing a heating cycle—wastes energy and indicates thermostat issues, airflow restrictions, or an oversized system.
If your heating bills have spiked without increased usage, your furnace is working inefficiently due to worn parts, dirty components, or mechanical issues that need professional repair.
"Our furnace went out at 10 PM on a freezing night in Canyon Creek. LEX had someone at our door within 30 minutes, diagnosed a bad ignitor, and had us warm again by midnight. The tech was professional, the price was fair, and they didn't try to sell us a new system. This is how service should be done."
