One of the ways we can waste our money on air conditioning is to choke off the airflow. A dirty filter or a register that is not fully open makes the air conditioner run longer than needed to get its job done. Anything that reduces the flow costs you money.
Oops, busted says the Energy Boomer. The register that I am talking about is the one located about two feet behind me as I am typing this.
I took the register up and played with the dampers that were obstructing the airflow. Then I looked down into the hole in the floor into the ductwork. An enterprising spider had constructed a web so well that it trapped dust and dirt just like an air filter. I had an extra filter that was slowing down the airflow.
After vacuuming out the ductwork, untangling the extension cords and fixing the register I could feel the improvement in the amount of air flowing out of that register.
Take a few minutes to check all the air registers in your house. Clear the magazines and newspapers away from them. Move the furniture a little to clear the airflow. Don’t forget to do the same for the return air registers too. Take the register covers off. Then poke the crevice tool on your vacuum cleaner into the ductwork as far as you can to clean it out.
Sounds like a lot of work on a hot day, but it is an inside job where your AC is keeping you cool. Remember its may be work but it will save your money on the electric bill.
The better the airflow the lower your electric bill will be. It is ok to block a register in an unused room in the winter, but I do not recommend it in hot weather. The more air flow through your air conditioning system the better it will do its job.
