They did exactly what they said they were going to do in a professional, courteous manner with expertise, at a fair price. What more do you need?After the old evaporator was removed, it was discovered that the new one had been damaged in shipment. I was worried because it was not a common brand, but a new unit was delivered to the house within 45 minutes and the job proceeded without a hitch. They cleaned up and instructed me on operation. I would gladly recommend.
