No Heat? Check These Things Before Calling for Emergency Heating Service
Simple Tips for Restarting a Furnace
A cold home doesn’t necessarily mean your furnace is broken—you might just need to make a small adjustment or “reboot” your system to get warm again.
- Make sure your thermostat is on—it sounds simple but without direction from these controls, your furnace won’t run. Replace the batteries in your thermostat and make sure it’s set to heat. Also check that the day and time are correct on programmable units that operate on a timer.
- Red light, green light—there’s a light on the front of your furnace—if it’s green, continue with this checklist; if red, call for service. Also note any flashing (i.e. two long flashes and two short ones)—the sequence helps us identify the problem for a faster fix.
- Check your power source—a tripped circuit breaker or blown fuse could be the reason for your furnace failure. Reset your breaker or replace the fuse to see if that restores heat.
- Check your filter—if it’s so dirty that your system is struggling to move air through it, your furnace could overheat and shut down. Changing the filter might bring back warm air.
- Reclose the furnace door—there’s a safety switch on the furnace door that prevents the fan and burner from running while the access panel is being serviced so if the door isn’t closed properly, your furnace won’t work.
- Clear leaves, snow, or debris from intake and exhaust vents—restricted airflow can cause overheating or system damage. Also make sure that curtains, furniture, and boxes are not blocking indoor registers and returns.
We hope these six tips are all it takes to troubleshoot your heating problem and help you get cozy again. But there’s one more tip we like to share: never skip annual maintenance. Many of the problems above can be caught and corrected during your yearly checkup. This means no interruption of service, plus the added bonus of cost-saving efficiency and fewer repairs down the road.
