Recent Review: This is the second time I've had Shafer do this -- once in my previous house and now in this one. I know they do good work and will treat me well. The two units in this house were 30 years old, and though they were still functioning, they were noisy and inefficient, and I knew they were on their last legs. I have a service contract with Shafer, and when they came out to do the spring AC check they said the system was too dangerous because of its condition, that we risked fatal gas leaks. Booth came out and spent a lot of time figuring out just what we needed, both for the size and layout of our house and the way we lived. He returned with options and spent a lot more time going over them with us, discussing factors including upfront cost, long-range cost because of differences in efficiency and kinds of units, and financing. Within days, a team, including Booth, came out to plan for the installation, which was a "unique challenge," as they said, because of the age of the old units, which were in the attic and installed upright instead of horizontal, and the old ductwork, which was configured oddly and not in a way that was good for us. It all had to come out through the attic hatch and ladder. Some of the attic had been turned into storage rooms which had to be cut into to remove and install ductwork. Some rooms in the house needed new vents installed and others blocked, and some new returns were needed. Basically, they needed to start from scratch after removing all the old parts. They estimated four days to complete the job and it took almost five because of a few unanticipated problems, but they guaranteed their original price. Oscar, Charlie and Steve were a pleasure to have in the house. They put down runners to keep the floors clean, swept up every day when they finished, did what they could to keep our lives normal, were pleasant, worked hard and even liked our dogs, who were not happy at all about the disturbance of their lives. Michelle, who mans (or womans) the phones, always keeps us informed about who is coming and when, and always knows what's happening. As good as everyone at Shafer is, I think she is what keeps the place functioning smoothly.
