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

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.

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.

Absolutely! Especially if you have an older home that currently doesn’t have air conditioning where installing ductwork just wouldn't work. No one likes being hot in the warmer months, so if you’re looking to sell your home in the near future, installing a ductless mini-split AC can be a good way to enjoy your home more while you’re in it, boost the return on your sale, and serve as a perk to peak buyers’ interest.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.
