"Signed up for the JG Cool HVAC maintenance plan in Mission Viejo, CA after a bad experience with another company." Every visit has been thorough and the technicians always explain what they found and what condition the system is in. This past spring they caught a refrigerant leak before it became an emergency. That proactive catch alone was worth the entire plan."
