Bill and his team installed a central air-conditioning system in our upstaIrs. They did an amazing job, finishing the work in 2 days, in 95 degree heat. The system worked great from the very beginning, and still like new. The job was so clean, and professionally completed, you could hardly tell anyone had done work on the house. He comes back annually and checks and cleans the system at no charge. William Snyder guarantees all of his work. A true craftsman. I highly recommend.
