We needed to have our AC compressor and coil replaced. We have a very difficult setup, with the compressor on brackets on the side of the house and the coil in a location that is difficult to reach and service. Both were put in by the original builder of the house with no consideration for how they would be replaced or serviced.
Despite these difficulties, Mark came and did a great job replacing the compressor and coil. This required extending the coolant line and rotating the compressor to make it accessible for future service. Mark worked late on a weekend to get all of this done for us, coming back on a Sunday pretty much all day to finish the job. He was not satisfied until everything was cleaned up and working properly.
The AC worked great all summer due to Mark's great work.
