Our goal in working with Penobscot Home Performance on our new construction was to end up with a home that was energy efficient, comfortable and healthy. We could not be happier with the results. Our heating bills this winter have been very reasonable. We have absolutely no drafts and the temperature within our home is remarkably stable despite significant outdoor temperature swings - even in the spring and fall when our heat and AC are off completely. Matt and Paul were extremely helpful and professional throughout the process. More importantly, they helped us prioritize the components of our insulation package so we could make decisions that let us get the most bang for our buck while staying within our overall budget.
