portant thing you can do to protect your investment is changing your pleated filter every time it’s not perfectly white or anymore…This usually is less than the recommendation of 90 days that it says on your filter, but rather about every month or two.Air filters are usually located at the furnace/air handler in the garage, closet or air return box. If you don’t see your air handler in the garage, closet or celling, chances are it’s located in the attic or under the house. In that case, the filter grille may be in the ceiling or low on the wall in the hallway. Either way, if you haven’t located your filter and are not aware of the components that make up your HVAC system, call Arizona Pro Service to come out to help you become familiar with it. Your system is a major investment in your house or rental property and if left unmaintained, you may have some high electrical and repair bills in the near future.
