It is recommended that an AC system filter be replaced at least once a month during the cooling season. Equipment manufacturers also recommend having the system cleaned, tuned up and inspected at least once a year. We have a great Discount Club Program that you can sign up for that will get you a deep discount on AC and Heating repairs as well as having your unit on a scheduled maintenance plan that will keep your system running more energy efficient for a longer time.
