Heating repair FAQs
Why is my furnace blowing cold air?
Possible causes include thermostat settings, ignition failure, an open safety limit or other control problems. A diagnosis is needed to identify the cause.
Why does my furnace turn on and off repeatedly?
Short cycling can be related to airflow restrictions, overheating, thermostat problems or safety controls.
Is it safe to keep running a furnace with an error code?
Not necessarily. If you smell gas, suspect carbon monoxide, or the system shows signs of unsafe operation, stop using it and seek appropriate professional or emergency assistance.
