"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."

"Gave the quality rating based on what I've been told and seen but they haven't done my work yet. Also doing windows & facia and soffit work plus roof vents. As we've been looking at some things we had considered, we've reviewed some of our options. Their willingness to help us do and get the best job possible done, allowed us to expand our agreement. We are now going to do another project and are working on referring Rick to some of our contacts who have work."

Energy Efficiency Auditing FAQs, answered by experts

Yes, advising on models that save electricity and reduce utility bills.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

While you can perform many routine home maintenance jobs yourself, it’s often a good idea to bring pros in for certain tasks. HVAC maintenance, fireplace and chimney inspections, foundation repairs, and roof inspections and repairs should be handled by professionals who know what to look for and can safely perform repairs. You may also find it helpful to hire a local house cleaning service to help with deep cleaning.

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.

Yes, skylights can affect a home’s energy efficiency, either positively or negatively. Properly installed, energy-efficient skylights with Low-E coatings, double glazing, and UV-blocking glass can help regulate indoor temperatures and reduce heating and cooling costs. However, poorly insulated or older skylights can contribute to heat loss in winter and excess heat gain in summer, lowering overall energy efficiency.
