They always take care of me.
I have been using Allied Services Inc., for too many years to remember. They have always responded if I call for any reason, and I always get taken care of. Whenever they're done servicing either my furnace or my AC unit, I'm always informed about the work that has been done. When I don't need service they come twice a year to check on the AC, and then the furnace for maintenance. The woman who schedules the appointments always calls me the day of to remind me, and to let me know when they are on their way. The techs then arrive, always on time. I have never had any problems with them. They are always friendly, polite, and professional.
