What a great team of people to work with at Comfort First. Renee McFadden, Installation Project Manager, answered all of my questions day or night. She responded almost immediately. She was very knowledgeable about heating systems, and took time to explain the difference and return on investment of a 14 vs 16 SEER unit. I found her to be very truthful, and very courteous! Then Ryan and Sean were the installation team! They worked hard with a smile, always willing to answer any question. Their work was great! And best of all, cleaned up everything. HVAC is working great!!
