I also learned that I should seal my windows because a lot of cool air can leak through that way as well.
In the area that I live, it can get extremely cold in the winter time. Last winter the temperature was in the negatives for a few weeks and my family had a hard time keeping the house warm when the temperature was so low. Last winter, I did a little bit of research on how I can save money on my furnace bill and still keep my house nice and warm. I learned that there are many ways in which the warm air can escape from your house, and there are simple ways to keep the heat from your furnace in your house. I learned that getting an air blocker for the bottom of my door ways would keep the cool air from flowing into my house. I also learned that I should seal my windows because a lot of cool air can leak through that way as well. I read online that an old air filter can harm your furnace and make it run less efficiently, so I got some new air filters for my furnace. After only a month of having these new air filters, I found that they saved me almost a hundred dollars on my HVAC bill! I was very happy also, when I realized that the heat in my house was not escaping even half as much as it had the year before thanks to my sealed windows air air blockers under my doors. These simple tips and tricks are what saved me hundreds of dollars on HVAC bills and also kept my house warm over the harsh winters.
