Professional, Knowledgeable, and Efficient!

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.


Response from Certified Heating and Air Conditioning:

Hi Justin, Thank you for the 5-star review! We love that you are happy with our install team, the installation of your new heat pump system, and our advisor Luis! Welcome to our Certified family. - Certified Customer Care Team

Great Service, Attitude and Work!

Let me say professional, polite, clean, no rush, exceptionally competent, scheduling to meet your needs and ready to answer any questions as well as taking the time to explain things if your so inclined to want to learn more about your HVAC system. Those are some of the thoughts that come to mind when thinking about my experience with Certified Heating and Air Conditioning. It started in the office with Kim's very pleasant and service oriented personality in setting up and scheduling my job and ended in the field with Brittany and Jill, who's experience and work ethic resulted in a job well done. I would definitely recommend this company to all. Keep up the good work and God bless America.
