Case Studies
Sometimes seeing an actual project is the best way to gauge how effective a contractor can be for your particular needs and situation. That is why we compiled a series of case studies for you to view.

Propane Tank Installation
Our clients had a whole house generator installed in their home. With the new generator, they required a larger propane tank than the one that they had initially.

AC Replacement
The Lyme Firehouse felt uncomfortable due to the poor performance of their window air conditioning units. Also, they wanted to reduce the high energy costs that come with these types of cooling systems.

Ductless Cooling
After many years of use, our clients decided that window air conditioning units were noisy, expensive to use, and their house still felt hot and sticky. Our homeowners wanted a better solution to combat the heat.
