Clean air is a precious thing! Anyone who suffers from allergies regularly will tell you that they really miss the days when they can breathe in and out deeply and freely, without sputtering into a cough or a sneeze.
However, did you know that your HVAC system benefits from unrestricted air flow just as surely as you do? Virtually every climate control system requires some sort of air filter. Nobody wants irritants or any kind of undesired particles floating through the air. An HVAC system’s air filter is supposed to catch this dust, dirt, dander, pollen, aerosol-based chemicals, etc. Trouble is, as you would fully expect, air filters get clogged after a while. At the point the air filter gets clogged, of course, air flow is restricted and your HVAC system begins to function poorly. It has to work harder to bring your home to your desired temperature that you set on the thermostat. Your blower is also overworking if your air filter is very dirty. Again, it’s just like trying to breathe through clogged sinuses. If you’re using a furnace, and the air filter has not been replaced recently, it may also cause the device to get too hot and shut off when you’re trying to operate it at high temperatures. Thankfully, in most cases, replacing the air filter with a fresh, clean one is simple, and can be done by anyone, nevermind just HVAC technicians. In fact, replacing your air filter for your climate control system is the most basic form of maintenance, and is very necessary!
