Our furnace went out on a weekend so we called several companies who advertised themselves as "emergency" ready. None of them even returned our call. So, we called One Hour Heating and Air - Bethel Park, PA and they were out here very quickly. They evaluated our system for us and decided they had to order a part out of Pittsburg. When it came in Monday morning, the next day, they were here first thing to install it for us. They were very professional people, and they gave us a written quote for the work. They were friendly and knowledgeable and they did a great job for us! We really appreciate how responsive they were!
