My guy plus I constantly forget to change the oil furnace filter on our heating equipment, however once a month you need to change the air filter! This is because after a month of use, the filter is clogged with dust.
The air filter is literally the only line of defense against dust getting in your system. Once it gets clogged, all the dust runs into the heater! Why is this super bad? Well first lots of dust in the furnace means the indoor air quality is going to be dusty! Breathing in dirty air is really disappointing for you plus can make you sick, and expect to sneeze, cough plus get headaches all from this, a bigger issue is that the dust makes the heating unit toil harder. With a layer of dust in it, the furnace has to power though longer plus toil harder to give heating. The worst thing ever is that if the furnace works too hard, it will overheat. Then the oil furnace heat exchanger could crack plus release carbon monoxide in the home. Or the oil furnace could catch on fire due to the dust, so evidently increasing the air filter once a month is a pressing deal. The more than one of us just can’t remember though. The people I was with and I tried setting alerts on our PCs, putting it on a calendar plus taking turns doing it! Nope, the people I was with and I consistently forget to do that 1, but super important job. One of these afternoons the people I was with and I are going to come to a burnt home or die from carbon monoxide poisoning since the people I was with and I were too lazy.
