I asked P and P Service Center come to the house this morning to evaluate my furnace and thermostat. They were very professional and courteous and informed me that the thermostat would need to replaced for a reasonable charge. They evaluated the furnace and told me that the furnace was in good shape. This was after another company (Lanz) told me that I needed a $2500 furnace bc it was cracked and malfunctioning. Thank God for honest companies like P and P Service Center! I am grateful for your integrity!
