There is no doubt that everything gets old.
It does not matter what it is.
It can be a human, a machine, a toy or anything really. Everything can get outdated & worn, but my pal and I all should know that at least. I know I have seen a lot of people come into & out of my life. I have seen a lot of children grow up. I have seen a lot of people die. It is just something that happens. My pal and I all know that electronics get outdated as well. Then, my friend and I buy something new. Even on our Heating & Air Conditioning systems they get old. They get a lot of wear & tear on their systems. It occasionally takes a long time for the wear & tear to take effect. Sometimes it does not take that long though. If people use their Heating & Air Conditioning systems a lot more or push their hot & cold temperatures actually high, it will cause it to wear & tear. If you do not scrub the filter it can cause wear & tear. A obstructed filter can actually cause your system to cut down. There are multiple weird ways to cause your system to get older sooner than you think. This truly same thing happen to me. It was causing airflow problems in my house. I noticed that there was not as much air coming through the vents as there had been. it turned out that there had been a obstructed air filter. The Heating & Air Conditioning system was pushing the air through the filter as much as it could. It was causing the system to labor much harder than before. This is what caused all the wear & tear.
