We want to stress at the start—which is why we put it in the title—that troubleshooting a furnace is not the same thing as attempting to do a DIY repair on a furnace. You won’t be taking out a toolbox, watching a “how-to” video on YouTube, and tinkering with the inside of the furnace hoping you can correct the problem. Not only is this usually ineffective, it can also be dangerous if you have a gas furnace and may be illegal in your jurisdiction.
If you go through all the troubleshooting steps we’ve listed below, which are all safe checks you can make to see if the problem with the furnace is simple, and still have the same problem, call us for professional heating repair in Germantown, MD.
Okay, important notice out of the way … let’s see what you can do about your non-heating furnace.
