My Furnace Died again on the Coldest night. Harry was over at 2am and fixed the problem but he told me the furnace was dirty. So Today Feb6th Monday I have another Service man here and yes the Furnace was not properly cleaned when I had a Tune Up in Sept 2022. Harry and this guy I have today are GREAT SERVICE people and REALLY know what they are doing and very THOROUGH Kathy Docos
