This past weekend was spring cleaning time at our house. It is the one time of the year, when we all work together, to make sure that the house is in good shape. My children do not love this time of the year, because I keep them busy, with menial chores. I really wanted to clean the air ducting in the house this year, which would take us half a day. I purchased a special set of tools, that are made just for cleaning out the air ducting. I was very surprised by the amount dust and debris, that we found throughout the air ducts. I didn’t realize the amount of dirt that was being blown into the house, until I started cleaning out the air ducts. When we were nearing the end of the job, I sent my son to the hardware store, as we were completely out of air filters, and needed an new one. I sent him with the old air filter, in order to make sure the proper size was retrieved. A few years ago, we had purchased an incorrect size air filter online. That had been a complete nightmare. When my son came home with the new air filters, I pulled one out to fit it inside the HVAC system. It did not fit at all. The air filter was labeled the same size as a old one, but it was clearly about an inch bigger. The new air filter did not fit in the system, and I was completely baffled. I contacted the hardware store, in order to explain the problem with the air filter. The hardware store replaced the box of air filters, which were incorrectly labeled.
