"Great. The energy audit identified the source of the humidity infiltration. And the audit report identified adjustments needed to the exhaust fan."

"Wonderful, it was a very quick and easy process. Brian talked us through it and in no time we had a 3KW system mounted on a frame in the garden and the invertor installed in the basement. Brian talked us through working with our power company to get the system checked and approved and we now get credits from the power company for power we provide to the grid. In addition we are set up to get Solar Renewable Energy Credits (SRECs) payments for providing clean energy. We also got a free Energy Audit which helped locate some problems areas we were able to fix. The system has basically cut our energy costs in half. I have hesitation in recommending them to anyone interested in solar energy."

Energy Efficiency Auditing FAQs, answered by experts

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.

A good SEER rating for an HVAC system is typically between 15 and 20. However, minimum requirements vary by location; HVAC systems in northern states must have at least a 14 SEER rating, while those in southern states need a minimum of 15. For the highest possible efficiency, look for units with a SEER rating of 21 or higher. It's important to remember that a SEER rating represents the maximum efficiency a unit can achieve, not the level at which it will operate at all times.

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.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

Replacing a window frame will improve your home’s energy efficiency if the old frame is cracked or damaged in a way that allows unconditioned air from the outside into your living space or if you upgrade to a more energy-efficient window frame material. Aluminum is the least energy-efficient window frame material, followed by vinyl and wood. Fiberglass and composite frames are the most energy-efficient.
