Review of Certified Heating and Air Conditioning

Chris, Nicholas, and Wyatt were extremely professional, knowledgeable, and efficient. They installed a heat pump for our HVAC needs. Completed in one day, I couldn't believe how fast it was. Luis who gave me the bid and quarterbacked the install was my point of contact for the whole process and made this whole process run smoothly. Overall my wife and I will be calling Certified Solar, Heating & Air Conditioning again for any future projects.
