If your furnace is blowing cold air or not heating your home evenly, there may be an issue with the burners, ignition system, thermostat, blower motor, or heat exchanger.
Banging, rattling, squealing, grinding, or popping noises often indicate worn components or mechanical problems that require attention.
If your furnace turns on and off frequently without completing a heating cycle, the system may be overheating, improperly sized, or experiencing airflow issues.
An unexplained increase in heating costs can be a sign your furnace is working harder than necessary because of worn components or poor efficiency.
Reduced airflow may indicate blower motor problems, clogged filters, ductwork issues, or other mechanical concerns.
Burning smells, musty odors, or persistent gas odors should always be inspected immediately by a qualified HVAC technician.
