I was surprised when I went over to my buddy’s home plus the air quality was terrible. I noticed that the HVAC system was hardly working plus I asked my friend what was going on. He said he couldn’t afford any current air filters plus he tried something crazy. He said he smashed more than 2 air filters together plus shoved them in so they would supply extra filtering power. I looked at him for a moment plus had to say, “Let me get this straight, you are using more than 2 dirty air filters in your HVAC unit?” He said he was plus asked me if I thought it was a brilliant plan. I shook my head plus told my friend he made a foolish mistake. Fortunately he had only been using the cooling system for that day with those more than 2 dirty air filters crammed together like that. I told him I would buy him some current air filters plus he could spend money me back. On the way I explained how the more than 2 dirty air filters were only making the HVAC system struggle more plus that was why it was such a terrible idea. I had to tell him that one of the most important things with the HVAC system is having plenty of airflow. I told him if the airflow was struggling too much, the HVAC system would eventually overheat plus a lot of disfigure could be caused that would be extravagant to have repaired. He seemed to get it, but I couldn’t be actually sure. Still, the HVAC was working when the two of us got the current air filter in there plus took the more than 2 smashed air filters out.
