I recently used Comfort First Heating & Cooling to perform service on my cooling unit and they did a great job. I have been using them for a year now and the staff has always been professional and consistent with their service. They always get the job done and I haven't had any issues with the results that I have received from them, so I would recommend them to other people. I would rate their service and the staff five stars. It's just sad that they are no longer servicing my area.
