From my initial contact to the continued follow up after the job is complete I have nothing but praise for the work, personnel and system. The technical representative visited my home and we went through my double HVAC systems from A to Z. I had specific needs which I clearly stated and each were accomplished during the installation. Follow up fine tuned the air registers and I've been 100 pleased with the A/C operation. This fall will reflect the furnace side of the systems but I have nothing but positive expectations. I already received the promised CPS/COSTCO rebates and look forward to IRS deductions. The systems were expensive but compare before you buy. I received other proposals and all were higher. I expect I'll stick with Beyer for the next ten years while my system is under warranty.
