“Jim’s attention to detail during the periodic maintenance check was exemplary. He discovered a failed damper we had not noticed. It resolved 2 rooms which had seemed hot in the summertime, but we thought were due to the windows getting a lot of sun. We consistently get great service from Heritage Heating & Cooling!“
