"I received my first electric bill since the installation of my new system and had a dramatic drop in monthly cost due to the efficiency of the new heating system. [O'Brien] told me it would be a much more efficient unit...he was so right!!"

Thanks to you personally and your people for a GREAT job. It's excellent equipment and was VERY professionally installed and tested. You can rightfully take serious pride in the work that was accomplished for us. Come & see and take photos if you wish. Your men worked with us. They both asked us questions and gracefully received our unrequested input. They did not rush, but worked to produce a quality finished product that they can be proud of in the most positive sense of the word !!!

Warren Greenwald, West Chester
