When I was first told how affordable my heating and cooling was going to be I thought this guy is not for real, but after receiving my heating bills for the winter of 2010-2011 I was convinced.I have a Envision 4 ton unit with 5 - 200' ground wells. My Feb 2011 bill for heating in Mitchell SD was $32.00 We have a 1600 SQ Ft old farm house.Thank you for the great system!
