Penobscot Home Performance conducted an energy audit of our house and completed the insulating and air sealing measures they had recommended. We’ve been very pleased. The house is quieter and more evenly warm, but the best result has been the impact on energy consumption. We have seen sharp declines in consumption of fuel oil and electricity. Our fuel provider fills our 275 gallon tank on a schedule dictated by degree days and past consumption patterns. There have been two deliveries since completion of Penobscot Home Performance’s work: one of 53 gallons, one of 44. In the same period a year ago, there were also two deliveries: one of 152 gallons, one of 149. At this rate, the investment in home improvement will very quickly pay for itself. Even better, we will have made major reductions in our carbon footprint.
