EarthTech Systems

EarthTech Systems operates as a heating contractor in Lowell, Massachusetts, with over 40 years of combined HVAC experience across its team members. Founded on principles of technical precision and customer education, the company holds an average rating of 4.0 stars from three customer reviews. The small, family-operated team specializes in geothermal HVAC solutions, serving homeowners in Lowell and the greater Boston area who are navigating the complexities of ground-source heating and cooling systems. Terry Queenan leads the company alongside his son Ryan, offering both installation and modernization services for existing geothermal setups.

What distinguishes EarthTech Systems from conventional HVAC contractors is their narrow focus on geothermal technology rather than spread across all heating and cooling trades. The team maintains long-standing relationships with specialized professionals including well drillers and ductwork installers, enabling them to coordinate comprehensive system retrofits from a single point of contact. Reviewers describe the company sharing live performance data from prior installations, supporting their recommendations with documented evidence rather than general claims. This evidence-based approach extends to post-installation support, where technicians remain available to explain system operations as homeowners become familiar with their upgraded equipment.

Customer reviews name technicians Terry and Ryan for their responsiveness and hands-on involvement throughout complex projects. When one Lowell homeowner inherited an outdated geothermal system during a year-long renovation, EarthTech Systems coordinated with a well company to replace the pump, install new equipment, and modify the nine-year-old furnace while continuing to answer questions as the homeowner learned the system. A second reviewer in the Boston area specifically credited the team for completing a complicated retrofit involving an existing geo system, noting that their 40 years of combined experience proved essential for achieving proper installation standards rather than shortcuts that would have compromised performance.
