New England Spray Foam is a registered Efficiency Maine Partner that services the entire state of Maine.

"It took two weeks and many calls & emails for Mark to respond to the problem of a leak in the system which caused damage to the ceilings & floor. When he called back we were told that his company didn't have the time to come out. He referred us to another company that does work for him. Two weeks later, someone came to look at the system, said they think they found the problem and told us if it leaked again to call back because we might need a new pump. Well, it leaked. We called. They didn't return the call. So, we called a local guy who was willing to come out that day. When my husband explained what we were told, he said there was no pump involved. And, he was right because with the information we got from the local guy, my husband was able to fix the problem in ten minutes. Very disappointed in the lack of and quality of service from New England Spray Foam."

Energy Efficiency Auditing questions, answered by experts

Replacing a window frame will improve your home’s energy efficiency if the old frame is cracked or damaged in a way that allows unconditioned air from the outside into your living space or if you upgrade to a more energy-efficient window frame material. Aluminum is the least energy-efficient window frame material, followed by vinyl and wood. Fiberglass and composite frames are the most energy-efficient.

Yes, skylights can affect a home’s energy efficiency, either positively or negatively. Properly installed, energy-efficient skylights with Low-E coatings, double glazing, and UV-blocking glass can help regulate indoor temperatures and reduce heating and cooling costs. However, poorly insulated or older skylights can contribute to heat loss in winter and excess heat gain in summer, lowering overall energy efficiency.

You can increase your home’s load factor by replacing fuse boxes with a circuit breaker, hiring a licensed electrician to upgrade your electrical panel, upgrading wiring, or installing subpanels. An electrical inspection by an expert can help determine the state of your current electrical systems and how they can be improved.

Installing weather stripping or upgrading to insulated panels can improve efficiency.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours.
