"We had previously worked with Energy Monster on a Mass Save audit and then adding insulation to our house. This time, we had the guys from Energy Monster back again to perform an electrical upgrade on our house (100 to 200 amps) and then install five ductless mini-splits for more efficient heating/cooling than our ancient terrible radiators. Despite dealing with a lot of obstacles -- a heat delay due to several 90 degree days and then tons of rain that prevented them from doing the outside work on the days they wanted -- the whole team was professional and efficient and made the most of the time when the weather finally cooperated! (Plus, my dog loved the whole crew and the loved him back.) It has been such a pleasure to work with Energy Monster as we turn our house into the energy efficient home of our dreams. Thank you!! We can't wait for Energy Monster to come back later this summer to install solar panels next!"

Inspired Electrical Solutions Inc specializes in the sales, installation and maintenance of generac automatic standby generators for your home or small business, and offers a full range of other services from home additions, to wiring, to electrical inspections and much more.

"The work is still on going but I cannot say enough about Inspired Electrical. Starting with the incredible service from the company's call screener (if that is the right term), Rosie, she put me on the schedule right away. Thomas was the first to my house. He listened intently to my description of the problem and proceeded to test the generator components, all while having B&S Technical support on the line. He diagnosed the issue as the rotor/stator had gone bad (B&S no longer manufactures the item for this model of generator). He then gave me an unofficial quote for for a direct replacement of a more modern B&S generator (direct swap) with a ten (10) year warranty. We also discussed adding my AC to the system. Later I scheduled a formal estimate with Scot. A true gentleman who explained everything step by step, to include looking for ways to get the job done and quoted me a price less than I expected as well as describing for me a future service contract for annual testing and maintenance at an extremely reasonable price. I'm waiting for the order of a new generator to be placed and then to schedule for the work to be completed. I expect this to be just as satisfactory as this review, but Inspired Electrical is my go-to for future generator and electrical issues!"

Energy Efficiency Auditing questions, answered by experts

The best way to save money on home heating oil is to get large deliveries in the summer months when the prices are lowest. However, this method will only work if you have a separate storage tank or an unusually large primary tank. You can sometimes save money by opting into a delivery contract, as some companies offer set prices that they believe will sit at the average cost over the contract term. If the price of oil rises, you could enjoy some savings, but keep in mind that you might also pay a bit more if the price decreases.

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.

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.

Depending on property size and audit scope, costs range from $200 to $600.

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.
