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

Provide utility bills and clear access to all areas of the home, including the attic and basement.

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.

Dehumidifiers typically use 300 to 700 watts of electricity per hour, whereas portable dehumidifiers use about 40 watts per hour. The exact amount of electricity your dehumidifier will generate depends on its capacity and energy efficiency. Generally, higher-capacity dehumidifiers generate more electricity than lower-capacity units, but they also usually have better energy efficiency over the long run.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home.
