When my husband died, I realized that it was going to be up to me to fix things around the house. It was a daunting task, especially since he had repaired everything for the last ten years. The first order of business was the furnace, which had been on the fritz for a few months. I read the user manual, and realized that the furnace filter was clogged. After changing it, my system regulated its own temperature much better, which was a huge relief. This blog is all about troubleshooting your furnace so that you can enjoy a comfortable, safe home.
