I am very pleased with the geothermal conversion of my Connecticut home.
“Rafael N.I am very pleased with the geothermal conversion of my Connecticut home. I expected the process to be significantly more complicated, but the Bell Mechanical team, led by Josh, worked efficiently and completed the work ahead of the budgeted time. I anticipate large savings now that my propane consumption will plummet. Next, I plan on connecting my boiler to the geothermal unit, which will cut monthly costs even more. Financially and environmentally, this project was the right decision for me.

Even got most of the cost covered through a warranty even though our system was 10 years old and installed by another vendor.
“We have a Geo Thermal HVAC system. Our system crashed during the hottest part of the summer. Chris & Ethan at Bell figured out what the issues where (there were several), made the necessary repairs and even got most of the cost covered through a warranty even though our system was 10 years old and installed by another vendor. Great team, service and repairs.”Jeff R.
