We first contacted Home Depot about doing the work since we had an existing credit account and could pay for the new unit with their "Twelve Months Same As Cash" deal. We were then contacted by an ARS receptionist the same day to set up an appointment with Eric Binkley, ARS Installation Manager, who promptly came out to our house, assessed our needs, worked with us on price, gave us two good discounts, and arranged an installation date within three days. The men who installed the new unit arrived promptly on a very cold January morning, had the old unit disconnected and in their truck in no time, and had the new unit installed, up and running perfectly in a matter of a couple of hours. They even checked on our existing humidifier under the crawl space, determined it was not draining properly, and fixed it without charging us extra! They did not have a new filter for the humidifier on their truck so Eric said he would order one and bring it out after it came in and installl it himself. ARS offers the first year of maintenance servicing free of charge. Thereafter they offer a yearly maintenance agreement with their customers to come out to service the unit twice a year for a very reasonable annual maintenance fee.
