O'Brien's techs did a fantastic job during our installation. They were professional, neat and courteous and we have and will continue to recommend them to others.
O'Brien Htg/AC installed a new heater and AC a few weeks ago. The owner came and explained exactly what we would receive and how it would be installed. The men who did the work were efficient and cleaned up everything before they left.
O'Brien Htg Air Conditioning in Us/Pa/Broomall is a wonderful caring company. Every worker cares about my problems - if any - and seeks to help me in every way possible. I almost feel as if they are family.
We required two units (upstairs/downstairs) and a Christmas installation with house guests present. Outside temperatures approached zero, thus a staggered and timely installation was necessary. This was expeditiously accomplished and programing of the units/thermostats thoroughly explained.
