Energy Technologies is the evolutionary product of the growth of the former Solar Source, Inc. In 1976, Solar Source specialized in the Solar energy field and made hundreds of effective Solar applications in Eastern Pennsylvania. In 1979, Solar Source had developed into a thriving HVAC service business specializing in heating and air conditioning, heat pumps, ventilation, air treatment, and refrigeration. In 1986, this growth and evolution spawned a new name: Energy Technologies, a company still dedicated to using the latest HVAC technological advances in a practical and cost-effective manner to provide our customers with exceptional heating and air conditioning service. In 1994, Energy Technologies became certified by the National Environmental Balancing Bureau to test, adjust, and balance air and hydronic environmental systems. In 2004, Energy Technologies became a Linc service franchise and joined over one hundred commercial HVAC companies all across North America and abroad. With Linc service we can now offer the integrity of a locally-owned business in combination with the expertise of a vast network of professional HVAC service companies to provide our commercial customers with reliable and cost-effective HVAC services.
