I have a service plan with Sears Heating & Cooling and a few weeks ago they did the spring service on my heating and air conditioning system. They cleaned everything and replaced the filter on the furnace. I have used them for years, and they have been very good about taking care of me. Once, my furnace went out on a Sunday, and they were here within two hours to get it back up and running. I appreciated that because it was very cold outside. They are nice people, and very professional people, and they really know what they are doing! I highly recommend them to everyone!
