There is constantly a good reason for everything, i suppose almost everyone should know that by know… Heating and A/C professionals would not just tell you that your Heating and A/C system air filter needed to be changed for no reason… Air filters can become truly so clogged.
In fact they collect so much dust and dirt in the matter of only a month! Some people have so much dirt and dust collect that they need to change the air filter every month.
Some people only change it every six months. However, you need to know your house and where you live. If you do not change the air filter often, there are some things that could happen to your home, then the air quality in your house goes down. The dirt and dust could start to travel through as it gets pushed right through the filter by the strong air being pushed through. The Heating and A/C system could stop working altogether. If the Heating and A/C air filter does not work, the system could have an automatic shut off in which it will not operate… Only some systems are able to do this though. If you do not have an automatic shut off, then you could potentially start a fire within your system. The dirt and dust could become so warm from trying to push through the warm air in the filter that it starts on fire. So, in no way is having a clogged air filter a good idea, then make sure to change your air filter on a typical basis. I promise that they are not lying to you. It is all for something.
