Hass Geosystems

Amazing people! I had furnace troubles on Saturday night/Sunday . We could fix it ourselves with out emergency fees ect. They came in on a Sun to sell us the part we needed for our furnace. Dennis also said if he didn't have my part, we would figure something out. The part worked perfectly and my furnace was running

Dennis and his crew (the two Mikes) did a fantastic job in the installation of duct work and retrofitting an over 100-year-old farmhouse to use a ground source, closed-loop geothermal heating/cooling system. The forced-air ductwork was ingeniously adapted to the decor, despite the wide stone foundation in the basement to restrict the layout. The cooperation of the Lake Region Electric Coop in burying the pipes using horizontal boring was clean & quick! The Climate Master heat pump worked well in the coldest January month of the year 2016 at a cost of about $200, without a dual fuel reduced cost of electricity (to under half). That's not bad for such a leaky old 1700 ft sq old farmhouse, which is insulated moderately well! Dennis Hass was faithful to work out the bugs" of the system and really knows his business! The project took quite a few months
