The best most responsive customer care team. Richair really does a good job at following up and helping you find a date and time that works best for you. The technicians are simply the best in the field!! honest, neat, clean hardworking and always on time and finish in a timely manner!! We are very happy the service receive from the technicians. Our unit it hard to reach, we have them come every 6 weeks to clean and every 6 months to perform maintenance. Every single time they are better than the last visit! I absolutely recommend Richair Comfort Solutions
