"I hired Albana Roofing to replace the Soffit and Fascia on my house. It's a family-owned company and everyone was super nice and very knowledgable. They did a great job, arriving at 8:00 am each day to work a full day. They even worked on Saturday to get the job done quicker. I recommend them and would hire them again in the future."

"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!"

Energy Efficiency Auditing questions, 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.

The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency

A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Fans reduce peak cooling loads, lower air conditioning energy expenses by expediting heat exit, and enhance natural airflow throughout the home.
