GNO Heating & Cooling Services

Here are some certifications we own. Excellence Certification: This certification is very similar to the NATE certification, but requires at least two years of professional HVAC experience. EPA 608 Certification: The Environmental Protection Agency (EPA) requires that all technicians who open a system containing a controlled refrigerant be certified to do so.
