Some people don’t keep air filters in their central heating as well as a/c, but while this can be a task for a little while it is very dangerous in terms of your heat as well as the air conditioning system cutting for good… Also, when you do not have an air filter in your central heating as well as a/c the heating as well as the cooling comes out rather dry as well as sporadically way too strong, then it’s awful for your skin as well as your health; how do I know all this? Because 1 time I went without an air filter for an entire month as well as it really made the air quality in our house pretty bad. Also I ended up having our entire central heating as well as a/c chop down. It was also sheer luck that it was able to be fixed, but as a result I also had to have our air duct deep cleaned because of all the dirt as well as grime that got in there from that whole month. It was also something that I will never even attempt again. I do not want the awful air quality or our central heat as well as the air conditioning component being cut down; plus our skin was so dry I felt extra horrible, so the whole point of this story is to say that you always should have an air filter in your central heating as well as a/c… No matter what—even if you do not remember to change the air filter 1 month, it will not do as much destruction as having no air filter at all!
