The company who installed two ClimateMaster units for me two years ago are no longer in business. I need one of the units serviced (low air discharge temp). Can any good tech service the units or should I use one listed at the ClimateMaster's website? And would my selection of contractor impact any warranty work? Only one of the contractors listed at ClimateMaster's website is one of their "GeoElite" contractors and they are 70 miles away. Not really an option. All the others don't have this certification. Also, the one that's out of business for over a year is still listed! A GeoElite dealer on their website is defined as: ClimateMaster GeoElite® Dealers are independent dealers who have experience installing ClimateMaster units and are trained, certified and selected by independent distributors of ClimateMaster products. So the other dealers listed on Climatemaster's website are not listed as GeoElite. Does that mean they have little experience in installing ClimateMaster units and are not certified to work on ClimateMaster products? I want to make a good choice and have a long and hopefully infrequent relationship with my new contractor. Any thoughts would be appreciated!
