My husband and I have been using Ron McMaster with McMaster Air & Heat for many years in our real estate career. We have successfully referred many clients to him for system upgrades, property rehabs and revovations. His equiptment reccmmendations are always right on, pricing always fair/competitive and installation and customer service are always excellent. He also just installed a complete heating system in our home that we are very happy with. Ron McMasters is an heating and air expert with high standards for his company and employees. I reccommend him highly.
