Ken did our annual furnace & A/C maintenance check up. Very thorough, focused, and knowledgeable. Politely answered questions or explained what he was doing. while continuing to work. Does not waste time. I will definitely ask for Ken if I should need further help from BILL HOWE in the future. Excellent maintenance technician! I have been recommending BILL HOWE to my friends for years. Ken is another example why. Thanks for the great service. Dan S.
