RM Mullinix has great service. They maintain our air conditioning unit and do a great job. The front office is very friendly and easy to work with. They are responsive and scheduling is convenient. The technicians are professional, courteous, and pleasant to work with. They are knowledgeable and know what they are doing. I like that they explain things clearly and answer all of my questions. I have no problems with the service and am happy with all the work that they do for me. I have already recommended RM Mullinix and will continue to use them in the future.
