When I made the call for service I was expecting sometime after the New Year. This company sent out a technician the same afternoon. When Chris arrived I explained to him the problem thinking it was just a stuck thermostat. He said he would check out the system. He informed me that a part was restricting the flow of Freon from the furnace to the compressor. He showed me and then told me my options. I verified everything he said with my HVAC brother-in-law in Chicago. Two days later, on Christmas Eve day, the installers, Mike, Danny and Paul arrived to install a new heat pump. These three men worked like a well oiled machine, in the rain, and had the job completed in just over six hours. Thanks for your professional work. Now all I need is some cold weather to test out the system.
