I have been using Cool Air solutions for my furnace/ AC unit since I bought my home in 2017. The employees have always been polite and courteous. They have always tried to explain what they are doing and how the system is working. Most recently I had an employee by the name of Daniel Tietze do the routine maintenance on my units. Not only did he explain everything but he also took pictures to show me what was happening and wrong with the furnace in my attic and why my AC was noisier than normal. He also helped me to get a better fitting filter in place. Truly a wonderful and professional person and it was a painless experience. I learned a few things too. Thanks so much for taking care of my home and my family.
