Truly excellent service! From the first phone call to request a quote, to calling to request service on the ductless unit Richair installed, they have been very responsive, courteous, and great at establishing relationships with their customers. The technician who came to run diagnostic tests on the ductless unit I have installed in my home was on time, absolutely professional, and an all-around nice guy. He was EXTREMELY helpful and knowledgeable about the installed unit and how to use it most effectively to keep my home cool. I definitely recommend Richair!
