“Greg is incredibly knowledgable and his entire staff are all very professional. We recommend them highly. We had ongoing problems with our old geothermal system due to a poor job of installation 15 years ago by another contractor. The entire system was in need of redesign and replacement including a new geothermal heat pump, new tankless hot water heater and backup propane boiler.It was a very complex job and Greg and his people did a phenomenal job. We have geothermal heat, backup heat, air conditioning and hot water all working perfectly. Greg has been very patient with me explaining everything step by step. My wife and I are absolutely thrilled with the new system.“
