I called McDonald Heating after my furnace wouldn’t stay running, kept shutting off randomly. They sent a tech out that afternoon to assess the situation. He was very friendly and professional and took the time to explain what happened and what needed to be done. Basically the lines kept freezing because they weren’t properly insulted, so he was able to get them warmed up and wrapped so the oil could pass through without issue. Haven’t had a problem since!Thank you so much! I would highly recommend them to all my family and friends!
