Cal Air Cooling and Heating did a fantastic job. They worked on my heating and air conditioning units and both have been working properly since. They were responsive and easy to work with. The service was convenient and straightforward. The job was done efficiently and completed in a reasonable amount of time. The technician was professional, courteous, and pleasant. He was very informative and answered all my questions. I had no major problems with the service and am happy with how everything turned out. I recommend Cal Air Cooling and Heating and will use them again if I need to.
