To ensure that you get your HVACEQUATOR checked before heating season and again before cooling season, Sears offers the Sears Maintenance Advantage Program. For less amount per month*, a Sears HVACEQUATOR expert tunes up your HVACEQUATOR system twice a year, helping it work optimally throughout heating and cooling seasons. As part of the program, if your HVACEQUATOR system needs a repair, we diagnose the problem free of charge and give you a some percent discount on repair parts and labor.
