Furnace FAQs

When your furnace is rapidly turning on and shutting off, this is known as short-cycling. Short-cycling is generally caused by a dirty filter, so ensure you’re changing your filters periodically. Short-cycling can have other causes, though, so call an experienced HVAC technician to diagnose the problem.

There are definitely steps you can take to ensure your furnace is in good working order! Cleaning the area around your furnace, changing filters, and cleaning your burners will allow for more efficient operation. DIY maintenance should be in addition to professional maintenance, as it does not take the place of your annual tune-up.
