I have wanted a 2-stage HP for years so when our 22yo 10SEER AC was nearing EOL, we jumped at the opportunity for a high-performance unit. My expectations have been exceeded: We love the dehumidification feature, the ECM air handler is able to reach the furthest corners of our house, I have to go outside to check if the condenser is running sometimes even though the unit is right outside our kitchen window, and the heat pump uses ~1kW less electricity while in the 2nd stage than our old unit. ComfortNet/Bridge took some learning but if you have patience and like to read then you'll be tuning your system in no time. Honestly, I ended up going back to many of the defaults because the whole setup is already quite efficient. We recently had a few <50F mornings so I have also been able to test the heat in action and am now looking forward to a cold winter to really stretch the system's legs!

Our old heat pump died and we needed a new one. I did a great deal of research and we chose this Amana model as the best value as it had a great price and great quality.

I guess I would say it is a high 5 but it is June and I have not used the heat portion of the system yet. The AC works great so far and sounds efficient. The calling mechanism is instant.

Performs satisfactorily. Outdoor unit is bit louder than expected. We built our house in 1990 in Central V. Passive solar with 6" framing and 24" of insulation in the attic, At 11 degrees F. the Auxiliary Heat never came on over the course of 4 hours.

We have only had this Heat Pump/Air conditioner for about two weeks--so far so good. It is easy to operate and does the job as expected. Bell Air Conditioning was very easy to work with and did an excellent job. We are pleased, so far.
