EST Program Information





 The Energy Services and Technology (EST) program offers a two-year Associate of Applied Science (AAS) degree. The program is designed to prepare students for technician level positions in the rapidly growing field of installing, maintaining, and troubleshooting high efficiency plumbing, heating, ventilation, and cooling systems in buildings. Graduates will work on systems that control water, temperature, humidity, and air quality of enclosed spaces within building structures. They will install various types of equipment used to control human comfort in residential, commercial, industrial, and institutional environments. This program will give the technician a working knowledge of plumbing and HVAC system building concepts and energy efficient design principles.  Incorporated within the curriculum is the International Association of Plumbing and Mechanical Officials (IAPMO) “Accredited Green Plumbers Training” curriculum.  Combined with the appropriate additional coursework, graduates will also have the necessary educational background and licenses needed for advancing into a career in renewable and sustainable energy systems.

Students enrolled in the PLB 101 class will be required to purchase the necessary tools to participate in the class.  The average cost for the tools is $600-$700, click here to see the complete list of tools.  In addition, students are required to have safety steel toe work boots.


Upon completion of the EST program, graduates can pursue:

  1. Green Plumber’s accreditation from IAPMO.
  2. State of Maine licensing in plumbing, oil burner, solid fuel, and propane and natural gas. 
  3. EPA refrigeration certification. 
  4. A career in renewable and sustainable energy systems.



Students must complete 67 credits in the Energy Services and Technology program and achieve a minimum grade of "C" in designated common and program core courses (*). Students must maintain a final GPA of 2.0 or higher.


Graduates of the EST program will find employment as entry level plumbers, heating, ventilation, and/or air conditioning technicians. They may also find employment as technicians for gas and propane systems.  Solid fuel technician positions may also be an option.  Graduates are encouraged to take additional coursework to qualify them for renewable energy system installers in such areas as solar thermal, geothermal, and biomass solid fuel systems.
