There are times that I just want to shake my head and refuse to help people, but that’s not allowed in my field of work. Unfortunately I have to take care of even the stupidest clients on earth, and help them as much as possible even when they don’t try to help themselves. When I hear someone tell me that their whole central air conditioning plan is not certainly working well, I wonder just exactly how long it has been since they had some modern and respected Heating, Ventilation and A/C maintenance performed. I mean, certainly I’m no longer surprised when I hear outright from the user of a non-actually working heating or cooling equipment that they don’t know what air filters are. It seems only natural to me, however then again, I happened to have went to university to learn all about heating, ventilation, plus A/C, so I better understand that if you, as the user do not change your air filter, eventually, you can count on the fact that something will go wrong with your Heating, Ventilation and A/C system. It’s really only a matter of time. When was the last time that you can recall changing your air conditioning filter for the family? There you are. If you can’t remember doing it before, you absolutely did not. So what then is actually happening to your dirty air filter while it is in use? Well, I will tell you that it is helping to force the rest of your Heating, Ventilation and A/C plan into absolutely working much harder. You want to change that air filter as soon as you can for the good of the system. Go ahead plus buy several while you are at the hardware store and stop making excuses.
