Backstory: Purchased a home in the past year that has ~30 year old 2 zone propane furnace and a/c system. A/c is on the way out (upstairs zone compressor is low on R22) and propane was shocking expensive over the winter (we had natural gas at prior home). I don't have access to natural gas but have electric grid power. I have 15 acres so plenty of land but it is on a mountain with relatively shallow bedrock (bedrock had to be blasted during original construction for basement). Researching potential options has led me to believe my best path forward for heating/cooling likely includes a combination of ground source heat pump for heat and a/c with solar array to reduce electric costs. Given the already present heat/a/c woes, I intend to implement the ground source heat pump first and follow with solar array later (say in a year or two). I have been lurking on here for months reading as much as I can. Ordered and read various books from Ashrae and IGSHPA so I am fairly up to speed on knowledge/nomenclature of these systems. However, I am finding it very hard to track down reputable designers/installers for ground source heat pump systems. Initially I was searching for HVAC designers/installers but got the feeling most were just playing lip service to get their foot in my door and then attempt to recommend a traditional furnace/a/c system while never intending (or wanting) to design or install a geothermal system. So I changed course and decided to call several local well drilling companies to see if a) they ever drilled vertical wells for geothermal systems and b) if so, who did they work with on the mechanical side. From this process, I got two names: Roger Locandro of Energy Smarts Mechanical in Stockton, NJ https://www.newjerseygeo.com/ Walter Kazar of Anew Solution in Flemington, NJ http://anewsolutioninc.com Has anyone worked with either of these individuals or companies? Any reason to use or avoid? Is there a better way to source out competent ground source heat pump designers and installers? Thanks in advance for any help you can provide.
