About Green Comfort

We engineer comfortable A/C efficiency, and fix the rest!


Green Comfort is a heating, ventilation, and air conditioning (HVAC) company that was founded in 2012 by Sean Gagen. Sean has been certified by the National Comfort Institute (NCI), North American Trade Excellence (NATE), and Building Performance Institute (BPI), as well as trained by the Department of Defense and National Air Balance Council (NABC). After receiving all of his training, Sean desired to provide customers in the Riverside and Corona, California areas with high-quality, scientifically supported, energy-efficient, money-saving, and customer-focused heater repairs, ac repairs, ac system installations, and ac system replacements.

Now, we call our technicians “HVAC Nerds” because they have also pursued multiple avenues of training and certification in the HVAC field. They are well prepared to complete your ac repair, your heater repair, maintain and repair your air conditioner, and install your new system to the highest standards. With that knowledge, we desire to serve our community by listening to their needs and providing design-based indoor air solutions to our customer’s indoor air quality, comfort, and efficiency needs.
