Due to some miscommunication, what should have taken two visits actually took 3. (Therefore cost an extra visit call.) No harm or foul. The job was misunderstood and not cleared up til visit 2. Once all got understood, they performed quickly and professionally and I'm fully satisfied. Very knowledgeable and neat. Replaced old R22 cooling unit with compatible unit at reasonable cost. Stood by quote even though some ducting had to be redone due to new industry standards. Good Company.
