As soon as winter rolled around this year, I knew that I had a problem. Our home heating system didn't seem to be working well, and it was really frustrating. We would wake up to absolutely frosty mornings in our own home, and so I decided to pull out the user's manual. I started researching different furnace problems and it occurred to me that the issue might be the filters. I checked them, and you wouldn't believe how full of dust and debris they were. After they were replaced and the air handler was blown out, my furnace started working again. Check out this blog for more information about troubleshooting your furnace.
