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

Heat pumps transfer existing heat instead of generating it, using less energy. Compared to baseboard heaters, they can reduce heating costs by up to 50% and provide efficient cooling, lowering electricity bills and carbon footprint.

The effect a gas fireplace has on your gas bill will depend on how often you use it, the size of the rooms you’re heating with it, and the BTUs of the fireplace itself, but generally speaking, it should only cost a few cents an hour to run it when it’s on. It will consume minimal energy when it’s “off” if you have a pilot light running constantly, but some modern gas fireplaces don’t require a constant pilot light.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.
