We had a new heat pump and air handler installed by Glenn Aire last April 2014. They did great work and were out by the end of the day. I purchased the dual compressor model that is supposed work less at lower temps in the hot weather. From Apr. to Dec. 2015 we used 2471 kilowatts less than we did the previous Apr. Dec. 2014. About $220.00 less for that time period.
Would highly recommend them. Matt did a great job explaining what we were getting and how every thing would go down.
