Last week HALCO installed a geothermal heat pump at our residence. I have only praise for the work they did, referring to both the outside excavated trenches and the follow-up removal of my fuel oil furnace and replacement with a Geostar 5-ton Sycamore heating/cooling unit. The team was thoughtful about the unique needs of our property, patient in explaining the steps, and thorough in removing dirt and debris that comes with these transformations. Very trustworthy and successful operation from start to finish.
