I have recommended Quigley on a number of occassions. In one case, my associate had two estimates on replacing his HVAC system. He decided to choose the other company because they were cheaper than Quigley. That company had recommended a smaller (less expensive) unit because his cu.ft. range was "borderline". When the summer heat hit he was very sorry. The other company just said - well, your space is on the large size for the unit you purchased. Quigley was honest and had the customer's best result in view.
