I have been a customer for many, many years and, in every case, the service provided by Appleton Campbell has been outstanding! Whether it be standard maintenance through the HSA program or an emergency call, these folks are simply the best! Our technician, Bill Dooly is truly outstanding...very professional, very friendly and courteous, and always willing to answer any questions I have regarding our HVAC system. My bottom line: "forget the rest, Appleton Campbell is the best!"
