Troubleshooting Furnaces: A Short Video Primer

Todays Home Inspector - Inspecting Your Furnace

One of the most used appliances in the home. It’s used for heating your home and many of the components are used in cooling your home. 


My furnace is 17 years old and it’s starting to give me problems.  I’ve had my furnace stop working about once a year for the past few years, but thankfully every issue I’ve had has been quite simple to fix, mostly because I know a few basic troubleshooting steps.

I was going to write a blog post describing some of these troubleshooting steps for furnaces, but I decided that a video might be a little easier to follow along with.  This video is by no means a complete troubleshooting guide to furnaces, but it’s a nice introduction to furnace troubleshooting.  I cover the most basic things to check, and I discuss some common error codes that furnaces may give.  For detailed troubleshooting and repair steps for furnaces, check out .  This is the best web site I’ve found that deals with furnace troubleshooting and repairs.

Part of what inspired me to make this blog post was an email that a reader in sent in.  The reader lives in a 2002 built home in Rosemount, and was charged over $2,800 (yes, Two Thousand Eight Hundred Dollars) for 1.5 hours of an HVAC technician’s time on a Tuesday (1/6/15).  That’s gotta be some kind of a rip-off record, right?  I’ll probably write another blog post in the future, giving advice on how to hire an ethical heating contractor.

I’m no heating contractor so I don’t know the exact numbers, but I’d guess that a large percentage of “no heat” service calls could be addressed by homeowners if they just knew where to start.  That’s what this video is all about.  Oh, and while watching the video, please ignore the part where the camera goes out of focus. I don’t know why that happened, but you’re not missing anything.

Without further ado, here’s the video:

I still recommend annual furnace inspections though.
