I have used R&R Mechanical Services for decades and they are an excellent company! Most recently, they came out and troubleshot a steam furnace for me. They found the problem, and then they fixed it! I can always count on them to do a great job for me. Their service techs are friendly people, and they are very well-skilled at their jobs. Very professional and very knowledgeable.They are extremely responsive, and they have a great deal of integrity. They do not try to sell me things I do not need. You cannot find a better heating and air company, and I highly recommend them!
