Extend furnace life.

The most common reason a heating and air conditioning system breaks down is because of a dirty filter. As dirt accumulates, air can’t pass, or worse, the system overheats. The motor then has to work harder. In a best-case scenario, your unit will need to be repaired.

By lightening the load on parts and preventing debris, replacing the filter is an easy way to lengthen the life of your heating system.

Reduce home energy bills.

When that clogged air filter is working harder, more energy is being used. And when it requires more energy to make your heating and air conditioning to work, it causes your energy bill to skyrocket. When you change your air filter on time, you can save up to 15 percent on your utility costs.
