When I was having breakfast at my brother’s house the other weekend, I noticed that the Heating plus Air Conditioning plan was running almost non-stop. However I recognized that was a problem, plus I also came to notice that the air quality wasn’t so great either. I was telling my brother about these concerns plus he said it was no immense deal; Since it was so dusty in his site, I asked him when he changed his air filter last… He seemed to be unsure so we both went down to have a look at his Heating plus Air Conditioning unit. I showed him where the air filter was plus when we shut off the Heating plus Air Conditioning plus pulled the air filter, it was truly filthy! I told my brother this was real bad news for the Heating plus Air Conditioning unit if he didn’t change that air filter every single month. He laughed plus said he thought it was supposed to be changed once per year. I looked at him in shock plus told him and said that a blocked air filter is a big deal! This was not a laughing matter–it could cause a great deal of damage to the Heating plus Air Conditioning equipment. If all that dust plus dirt works its way into the inner workings of the equipment, it causes everything to stress plus overheat. With decreasing the air filter only once per year, I felt he was lucky that his Heating plus Air Conditioning plan was still working! So we went to the store plus ordered some quality HEPA air filters… They were a bit lavish, despite the fact that I told my brother this would improve the air quality plus protect the Heating plus Air Conditioning system. His plan worked so much better when we put in that new air filter, plus I could even tell the air quality improved a little bit.
