Lancaster Plumbing Heating Cooling & Electrical did a great job getting my heat working again. They were recommended to me by my brother in law and I'm so glad he recommended them. Mark and Ander were the servicemen and they were prompt, quick to get the work done, and called me with an update on when they would arrive. They were both professional, polite, and wore shoe covers to protect my floors. I asked them for business cards while they were here and I have already recommended them to several people.
