Air filters are the unsung heroes of your home comfort system. They have one of the most important jobs in the system, but they’re often forgotten — to the detriment of your budget. Clogged, dirty air filters cost you money by lowering system performance and driving up utility bills. A dirty filter can shorten the life of your system, too. It’s well worth the small amount of time and effort required to replace the filter monthly, especially in seasons of heavy use — throughout the summer and winter here in the Grand Traverse County area.
