Found out works better with a simple thermostat than with the smart one, Cooling is a little loud but only if you are outside and near compressor fan inside is medium in sound but does reach furthest rooms.

Going Strong

This system has been very reliable and dependable. Very little maintenance required. The system has stood the test of time and weather. I would recommend Carrier for its economy and freedom from repairs.

Very Reliable

The system has been very reliable with no problems. I installed a completely new Carrier system 6 years ago along with ductwork. My AC bill dropped by $50 dollars a month in the summertime with carrier. I also love the 10yr warranty that came with the system.
