I have worked with the folks at Protech for at least eight years. They began by designing a state of the art heating/AC replacement system which was followed by a great, clean installation, at a good price. Since then I have continued my service with semi-annual checkups. Throughout the professionalism has been the best. This is a family run, local Santa Fe business which provides some of the best on time and technical service I have experienced. These folks are always on time and their prices are reasonable. Everyone, I repeat everyone, I have dealt with has been top notch. If you want to keep your service dollars local, I highly recommend Protech. You will not be disappointed!
