Common symptoms

No heat, short cycling, unusual noises, weak airflow, inconsistent room temperatures, or repeated shutdowns can all justify service. Gas odours or suspected combustion problems require immediate safety action and professional guidance.

Information to prepare

Record the furnace brand and model if accessible, thermostat setting, visible error codes, filter condition, and when the issue started. Explain whether the system fails continuously or only under certain conditions.

Questions before repair

Ask about diagnostic fees, whether the proposed repair addresses the root cause, what parts are being replaced, and the warranty on the work. For major repairs, ask whether replacement should also be evaluated and why.

Frequently asked questions

Should I keep restarting a furnace that shuts down?
