Every month for the last six months, I have watched my energy bill get a little higher. At first it was just a couple dollars. This month it went up over $10 more than the previous month. Over six months, my energy bill has gone up over $40. I have never seen my energy bill this high. I knew that there had to be something in my house that was causing this much of a raise. I started checking to make sure all the lights were out and that my daughter hadn’t forgotten to unplug her blow dryer or curling iron. I know she had done it before. I also checked to make sure the thermostat was all turned off in the unused rooms. When I ran out of energy thieves to check, I called the HVAC company. I wanted them to do an energy loss test on my home. When the HVAC technician finally arrived, he asked when I had last had my ductwork cleaned, and if I had my air conditioning unit serviced. I admitted I had forgotten to have the AC unit serviced, but I had never had my ductwork cleaned. The HVAC tech told me that if there was a lot of dust and debris in the ductwork, it could cause the HVAC system to work harder. When the HVAC system was working harder, there was more energy use. I had the ductwork cleaned and the AC unit serviced. Now, I just need to wait to see if the energy bill goes down over the next two bills.
