Can you believe today is March 1st? Where have the first couple of months of 2013 gone? Since today is the first day of the month, here’s a friendly reminder from Elmer’s One Hour Air: Change your air filter! Make it easy on yourself to pick up the filter-change habit. Picking a day like the first of the month or the day you make your house payment are probably the simplest. Also, make a monthly reminder on your smart phone. Your air conditioning system will thank you!
