"I needed to replace fiberglass insulation that was anchored under a crawlspace. Energy Monster did an evaluation, told me about the Mass Save program, suggested insulation that would work much better than what I originally contacted them for, and installed new fiberglass and foam board, sealed the edges, and cleaned up afterwards. I'm very happy with the work and will definitely be calling them again next year to add insulation to my attic."

"These guys were fantastic! Mike really knows his heat pumps and it showsâ he was always available via email when I had a question, he walked us through the entire process for applying for the state heat pump rebates, and we couldnâ t be happier with the system one year in. Because of our Initial positive experience with Mike, we also hired Energy Monster to do our solar panel installation. Top notch, LOCAL company!"

"I couldn't be happier with Joe and his crew.  From first contact and the time we met to get an estimate I could tell right off the bat he knew exactly what he was talking about, and was very professional about everything.  I met with 2 other contractors, and even though Home Facelifters wasn't the cheapest, I knew that they would get the job done right and on time.  They dealt with all of the city inspectors and dealt with pulling all the permits, they helped me pick out many of the different items for the house like the cabinets, counters, appliances, flooring, and even colors for the walls.  There were some things that I thought I wanted a certain way but Joe was always willing to try and explain why another way might be better, which I do appreciate.  The payment process was very simple, we did go over our original estimate, but he had told me upfront there was a chance we would find things behind the walls that we couldn't predict, and I was prepared to possibly go over by a certain amount so that wasn't a problem.  The work was done very quickly, and the quality of everything is great.  I will definitely be using Joe and his crew on future projects of mine.

Energy Efficiency Auditing FAQs, answered by experts

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. 

Yes, Tesla Powerwalls are worth the upfront costs, as you can recoup your investment within six to eight years. Plus, they provide peace of mind that you'll have power during a power outage, and, depending on the system you install, you can become energy-independent. While they may be more expensive than other solar power systems, they offer higher battery capacity and lifespan.

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.

Typically, triple-pane windows made with krypton gas filling are the most energy efficient. A window’s frame, glass, design, and installation all affect its energy efficiency. These windows, in particular, are designed highly effectively in terms of their ability to insulate.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.
