"I recently had my attic insulated by this company and had a great experience from start to finish. The entire process, from the initial energy audit to customer service and the final installation, was smooth, professional, and well organized. The crew was incredibly kind, hardworking, and patient with all of my questions while they were on site. You can really tell this is a business with a family feel — everyone treated us with care and respect, and it made the whole experience much more comfortable. I would recommend."

I conduct energy audit tests for homes, whether they are colonial or brand new construction. I can recommend you various forms of weathersealant, thermal wrappings, and storm window techniques, saving you thousands in the form of long-term heat insulation tech-forward solutions.

"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

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

Energy-efficient windows cost more than other window types, but they can help you save on your monthly energy bills, get you some breaks on your taxes, and even increase the value of your home. According to Michael S. Regan, Administrator of the U.S. Environmental Protection Agency, when people invest in green upgrades like energy-efficient windows, they save energy, money, and more.

Yes, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.

String lights require electricity, but not an excessive amount, especially when compared to other lighting fixtures. LED rope lights, for instance, consume around one watt per foot. Running six or seven light strings simultaneously should only cost you around $10 to $15 each month. You can save even more money by remembering to turn off your lights during daylight hours. 

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.
