One of the best things a homeowner can do to help their furnace last longer is to keep the air filter clean.  In most homes the filter needs to be changed monthly during the winter months of heavy usage.  A plugged or dirty filter keeps the furnace from breathing and moving enough air.  This then causes it to overheat, which uses more energy, and causes the equipment to fail prematurely.  If you choose to use 1” pleated filters like you can get in the big box stores, be aware that while they are great filters (maybe too good) they tend to restrict the air even when they are new and clean.  As they “load up” (get dirty) it makes the problem even worse.  They will need to be checked even more frequently.
