We have been using Dean Mechanical Inc. for at least the last five years or so, and we definitely feel comfortable about recommending them to others. Their workers show up on time when we call them, and they are very friendly people who do a very professional job. One thing that really impresses us about them is how well they work with our own maintenance staff. They stay in contact with them, and they let them know what is going on at all times. That is essential in this kind of business. Absolutely Five Star service!
