We offer consulting services, general contracting, full scale integration, installation, sustainability services, and cost-effective energy solutions for commercial, industrial, residential, retail and non-profit customers.

"Lomont and his team were great to work with, simply professional, knowledgeable and so accommodating. I hired him based upon an energy audit we had done by another company. He basically "cleaned up their mess" since they did not do a thorough report in order for us to get our energy rebate etc. He went above and beyond the scope of what we hired him to do, always with a friendly greeting and smile. He reached out to the appropriate agency to push to get the credits we were due and did work that should have been done by the energy audit company. I highly recommend Lomont."

"Charter Oak Mechanical came to my home for a routine air conditioning maintenance visit. During their service, the condenser fan motor failed on a relatively new unit (only 7 years old). Since then, I’ve been left without air conditioning during a severe New England heatwave. At the time of the incident, an apprentice was cleaning the outside unit unsupervised while the lead technician was working on the air handlers inside. Shortly after, the condenser fan motor broke down. This raises serious concerns about oversight and professionalism during the visit. When the issue occurred, the owner personally called me, empathized with my situation, and said he would try to help. I appreciated that gesture and hoped it signaled a commitment to resolving the matter. Unfortunately, I’ve been unable to reach him since. The receptionist and service manager have not connected me with him, nor have they provided clear or honest updates. What’s been most disappointing is the attitude I’ve encountered from staff. I’m not sure how customer-friendly or helpful they intend to be until this is resolved. The lack of transparency and responsiveness during a time of real discomfort has been frustrating. I’m still hoping Charter Oak steps up and delivers the service and accountability customers deserve. I will update this review based on how the situation progresses."
