Upgrading A/C, which Controller Infinity or EDGE
We are going to need to replace our A/C unit in the near future. It is a 8yr old Heil 12 SEER 3 ton, and has a good amount of corrosion, to the point the fins are flaking off when touched. We live in Southern NJ, about 8 miles from the coast. Our existing furnace is a Carrier Infinity 96% 58MVB080. The main problem is the coil is only 10-12 SEER, and is below the furnace, so replacing the coil would entail removing the furnace.
We are looking at either the Carrier Performance Series or the Bryant Preferred Series. What is the main differences between the 2 levels of thermostat Carrier Edge/Infinity (or Bryant Evolution/Preferred)? Which one would you suggest? Also, are the Bryant thermostats compatible with the Infinity furnace. Thanks.
