We are in the property rental business, and Kellam Mechanical does a great deal of work for us on the heating and air conditioning systems. They are friendly and professional people, but most importantly for us, they are extremely reliable people. If they say they will be at a property at 10:00 AM, then that is when they are there. They do excellent work, and that combined with their reliability makes them a great company to do business with. We highly recommend them to everyone! They are a good company!
