I have been using Snyder Heating and Air Conditioning for five years. I have had them work on several projects. The installed a brand new system, redid some duct work in my attic and added return vents. They do all of the maintenance on three of my properties. I have them come out twice a year. I continue to use them because they do a good job and are reasonably priced. Typically I request that Kenny come out. He does quality work and is a very nice guy. Amanda in the office also provides excellent customer service.
