I really appreciated the time Frank Gallant spent with me detailing the options for my furnace and outdoor air conditioner. He was very candid and I feel that he truly had my best interests at heart with regard to the best course of action I should take. Thank you again.

Smart Heating & Air Conditioning not only installed a new AC unit for our home at a great price, but installed it the day after they came out for the initial estimate. That was a lifesaver because we are expecting family from out of town this weekend — which is expected to be a scorcher.
