Allied Services is excellent. They provide great services for a great value. My family had actually been using Sears for all of our air conditioning and heating needs, but they would always take too long to come out and charged too much for their work. We decided to try out Allied Services, and they have always been professional, skilled, and timely. More recently, they really helped us with a strange incident. We found a raccoon nest inside the cabinet of our air conditioner, about as big as a kitchen sink. We needed someone to replace one of the sensors, and Allied arrived promptly and got the job done. We have been using Allied Services for a while now, and will of course continue to do so.
