“Ground Loop, and in particular, Toby and Scott, get 5 stars for finally resolving what had been many years of frustrations regarding my geothermal cooling upstairs. The system installation, and its bi-annual maintenance, had been performed by another company. I had complained for several years about the upstairs cooling not being able to maintain at the thermostat setting during the hot summer days. They offered a variety of ideas, including the installation of a new air handler (an expensive non-fix), none of which improved the cooling. My builder suggested Ground Loop for a second opinion. Toby immediately observed multiple compressor leaks as well as poor pressure readings. Mind you, the system had just been inspected 2 months earlier by the installation/maintenance company. Scott made recommendations and oversaw the work. Finally, my upstairs is maintained at the thermostat setting for the first time in many summers. These guys are professional and knowledgable, and communication has been great! Highly recommend!!”
