Cool Tech Mechanical does great work! I have used them about 4 or 5 times for various services and they have always performed well. When my heating unit stopped working, they resolved the issue for me. They also do regular maintenance service for my heating and air conditioning units. The technicians are always on time, professional, and pleasant to work with. Their thoroughness goes above and beyond what I have experienced before from other companies. They always follow up with me and make sure I am updated on what is going on. I also appreciate their prompt response time and timeliness. Their pricing is reasonable for the work that they do and I will continue to use them in the future.
