Installed our Business Heating & AC Units - Great Service. We had an old AC & Heating unit go out on top of our building. We have two of these old units, and one of them was so old that turning on the heat would have been a safety hazard. Shaun Holmes came by and gave us a quote for the replacement of one of the units, and a cleaning\tune up on the other. Not only did he quote us at a flat rate, as soon as we could come up with the money, we said Go and he was here in two days. It was not a small job - they had to bring in a crane to put the unit on top of our building. Each time we called, to get in touch with him, we received a return call in a very timely fashion. On a personal note, he also gave me a quote for a water softener (even though it's not his area of expertise. He took the time to call someone an get the details for me - which he did not have to.) I would recommend Neerings, and especially Shaun.
