We just bought a different home with a Bryant system. The Heat pump is a model 265ANH048000 4 ton (15 SEER) and the coil is a CNPVP4824ACA. We had the system serviced and the Technician told us that the coil that is installed isn't rated for a 15 SEER Bryant Preffered Series Heat Pump. He said the coil is for a 13 SEER unit. I looked up the coil on the web and it's an "N" coil?? There is little space for the coil so maybe that's why an "N" type was used? Anyway, he suggested we get this fixed so we can enjoy the higher SEER rating of the Heat Pump. The system seems very nice and quiet. The house feels really comfortable all the time but we do want to be energy efficient. Comments on the system match?
