We have been using Allied Services for the past four or five years. We've had them work on several things in our home for us. For the most part, it's all been extremely good. We had Allied Services install a new water furnace for us, and we couldn't have been happier. There were, however, some bad experiences, but those had to do with issues that the manufacturer was giving us. They are very honest and upfront with us about everything. They let us know exactly what the cost of equipment will be. They make sure they know what our expectations are. They always come when we need them to. They usually send a different technician each time, but we have gotten to know some of the staff who helped us deal with issues that our manufacturer was giving us. We're very impressed by their communication skills and their integrity. We're very happy with their service and will continue to use them.
