Lake HVAC was founded in 1975. For more than 40 years, Lake HVAC has built and maintained quality HVAC systems for industrial, commercial, institutional and high tech/biotech clients in Massachusetts and New Hampshire.
We work with general contractors, developers, facilities departments and engineering firms to ensure that our clients receive efficient, reliable, and cost-effective solutions for their HVAC systems. Our professional experience in HVAC installation, service and design ensures your project will maintain long-term functionality, efficiency and return on facility investment.
Great companies start with great people, and Lake HVAC is committed to hiring and retaining highly trained technicians and staff. We recruit the best talent – and then we help them advance their careers through on the job training and continuing education.
Our team is highly trained and motivated to meet every challenge with innovation, quality workmanship, and integrity. Lake HVAC leads the way in building a culture of teamwork and safety. We value our employees, and as a result have experienced very little turnover with many of our senior staff working together for over 20 years.
The knowledge, experience and know-how of our seasoned team help to ensure smooth processes and a safe work environment on every project. Many of our employees hold master licenses in Massachusetts for refrigeration, pipefitting and sheet metal.
