"O'Connor's has installed gas boilers and hot water tanks in two of our properties. Both times the work was done on time and at the price quoted. The installers were friendly and professional. I always recommended O'Connor's to my family members and my friends."

Mike Z., Johnstown, PA

"Our furnace stopped working on one of the coldest days this winter. I called O'Connors and they were able to get it up and running in just a few hours. The service man was so nice, too."
