I recommend At Parker Service Company for any repair job for your furnace. My furnace was not working as it should and was causing problems. They were prompt to send a technician for the furnace repair. The technician had the problem diagnosed quickly and explained me the cause of the trouble. He ordered the replacement parts, picked up and installed them in a couple hours. Everything was done in a quick manner and the technician explained everything he was doing. I will use this company again in the future.
