Frequently Asked Questions About Furnace Repair

Your Furnace Repair Questions Answered

Multiple issues prevent furnace operation. Check your thermostat settings and batteries first. Verify the furnace switch is on and circuit breakers haven't tripped. Common causes include failed igniters, faulty thermostats, tripped safety switches, gas supply issues, or control board failures. If basic checks don't restore operation, professional diagnosis is needed to identify and repair the specific problem safely.

Short cycling indicates various problems. Oversized furnaces heat too quickly, causing frequent cycles. Dirty filters restrict airflow, triggering safety shutoffs. Thermostat placement near heat sources causes false readings. Faulty flame sensors shut down burners prematurely. Our 38 years of combined experience helps quickly identify whether it's a simple filter issue or complex control problem requiring professional repair.

Cold air from vents has several causes. The furnace might be in fan-only mode - check thermostat settings. Pilot light or ignition failures prevent heating. Overheating from dirty filters triggers safety limits, running the fan without heat. Cracked heat exchangers activate safety systems. Gas supply problems prevent proper combustion. Professional diagnosis determines the specific cause and appropriate repair.

Furnace sounds indicate specific problems. Banging suggests delayed ignition or expanding ducts. Squealing indicates belt or bearing issues. Rattling might be loose panels or motor problems. Clicking could be normal ignition or failing components. Humming suggests electrical issues. Scraping means metal-on-metal contact requiring immediate attention. Document when noises occur to help technicians diagnose quickly.

Heat exchangers typically cannot be repaired - only replaced. Cracks allow dangerous carbon monoxide into your home's air. While replacement is possible, costs often approach 50-75% of new furnace price. For furnaces over 15 years old, complete replacement usually makes more economic sense. We perform thorough testing to confirm cracks and provide honest replacement recommendations prioritizing your safety.

High heating bills indicate efficiency problems. Dirty filters force longer operation. Leaking ductwork wastes heated air. Poor insulation increases heat loss. Aging furnaces lose efficiency over time. Improper thermostat settings waste energy. Gas pressure issues affect combustion efficiency. We diagnose the specific cause and recommend solutions ranging from simple maintenance to system replacement.

Furnace repair involves significant safety risks including gas leaks, carbon monoxide, electrical hazards, and fire dangers. Professional technicians have proper training, tools, and safety equipment. DIY attempts risk personal injury, property damage, and liability issues. Even seemingly simple repairs can have serious consequences if done incorrectly. Always choose professional service for safety.

Annual professional maintenance is essential for safety, efficiency, and reliability. Schedule service each fall before heating season. High-use systems or those in dusty environments benefit from bi-annual service. Between professional visits, change filters monthly during heating season. Regular maintenance prevents most emergency repairs, maintains efficiency, and extends furnace life significantly.

Carbon monoxide is odorless and invisible, making detectors essential. Warning signs include yellow or flickering furnace flames (should be blue), excessive moisture on windows, rust on vent pipes, or flu-like symptoms improving when leaving home. If CO detectors alarm, evacuate immediately and call 911. Never ignore potential CO issues - they're life-threatening.
