Daniel Hebert Inc. has over 80 years of experience in the HVAC industry. Our reputation for quality workmanship and industry standards is second to none. We continue to stay on the forefront of technological advances in this field with systems such as geothermal heating and cooling.


With the escalation of the prices of fossil fuels, there has been a serious push for alternate forms of heating. Biomass boilers have increased in popularity as they can provide significant energy cost savings to many facilities while still meeting state and federal regulations for emissions. Daniel Hebert Inc. successfully integrated a wood chip biomass boiler into Weeks Medical Center in Lancaster, NH in 2011. Our vast mechanical knowledge and years of experience working in and around hospital environments were instrumental in completing that project with minimal inconvenience to hospital staff. Weeks Medical is now seeing substantial energy savings. Contact Daniel Hebert Inc. about having a cost analysis done, to see if a biomass system is right for your facility.


Another technology that has been gaining popularity as an alternative to burning fossil fuels is geothermal. This is the process of using the earth’s heat as a constant source of temperature for water-to-water heat pumps. Geothermal has emerged as an environmentally friendly, cost-effective approach to heating and cooling a facility. Daniel Hebert Inc. has installed geothermal systems in both the Border Patrol Station in Fort Fairfield, ME as well as the new MOB at Littleton Regional Hospital. Both systems have exceeded expectations in cost savings and building comfort.


Daniel Hebert Inc has been designing and installing HVAC systems since 1928. We are qualified to install several different varieties of mechanical systems. Our staff includes licensed plumbers, gas technicians, refrigeration specialists, and medical gas technicians. We specialize in value engineering and cost savings to our clients, while still holding an extremely high standard of workmanship.
