The nice people of Arctic Air sold me on their Service Agreement. I hate trying to remember to change out the air filter in my furnace/air conditioner. I never seem to remember it and I know it is so important for the efficient operation of my unit. With an their Service Contract, Artic Air comes my home twice a year, in the Fall and Spring, and service my system and get it ready for the heating or cooling season ahead. That is some of the best money I’ve ever spent. It gives me peace of mind that my system is being taken care of properly and will extend the life of the system.
