Three-inch or smaller filters should be replaced after 90 days; larger units need to be changed every four months. This type of heating and cooling system maintenance can prevent health problems, enhance comfort, reduce air pollution and cut operating costs.

They have the potential to raise fuel or electric power consumption by as much as 15 percent. For example, a dirty air filter could boost a home’s annual cooling costs from $900 to $1,035.

It may begin to cause mechanical problems after excessive amounts of dirt accumulate on coils or motors. This results in costly service calls, repair work and part replacements. Another problem is that it may force
