"Edge Energy did an energy audit for us, then sealed the house, installed a new roof with excellent insulation, and an ERV fan to ensure fresh air. They were a delight to work with throughout, very friendly and professional. We needed some follow up work due to quirks in the house, not bad work by Edge, and they did it promptly and without charge. I couldn't recommend them more highly."

"Very well. Technician, John, was patient and thorough as he cleaned and took readings of the systems. He took the time to walk me through the maintenance and care that I need to take care of the Heating and water heater systems of my newly acquired condo in Fairfax County Virginia."

"Very easy to work with. Their repncame out and did a free home energy audit in a timely manner. They then go over over everything they find. He walked me through everything he found. The list he came up was priced out but was definitely a little more than I wanted to spend...but he worked with me to figure out what items to fix that would give me the most bang for my buck at the cost wanted to spend. We definitely notice an improvement in the house from the fixes. I would recommend these guys."

"Our LG above stove microwave stopped heating. Lucky from Reliance Repair came out and gave us an estimate. He arrived on time. His estimate was reasonable. When he received the part, he returned on time and worked diligently to repair the problem. He was polite, respectful. Overall, an excellent repair experience. Highly recommended."

"We wanted to try a local contractor and came across Evergreen by chance.  It was an excellent experience.  Thad was knowledgeable and professional and easy to work with.  The crew was exactly the same.  Nice, respectful, competent.  The worked around my crazy schedule as we had other improvements going on.  They had a slight delay in getting the generator as there was a back order, but called and let us know and we worked around it.  Laurie in the office was equally good and kept us in communication on details or things to do and schedule etc.  I could not be more happy with the experience on such a big purchase.  They were always accommodating and helpful.  The Generator and switch were high quality and I think the price was fair.  They even did some easy side things for us for no charge.  We will definitely use them again soon to install an attic fan."

Energy Efficiency Auditing questions, answered by experts

Electric bills tend to be lower in spring and fall because people use less electricity during these seasons. Milder temperatures allow for less use of heating and cooling, unlike during winter and summer, which usually bring more extreme temperatures.

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.

R-value measures an insulation material's thermal resistance, indicating its ability to resist heat transfer. A higher R-value signifies better insulation performance because the material is more effective at slowing heat flow. The R-value depends on the type, thickness, and density of the insulation material, such as fiberglass, foam, or cellulose. Each inch of insulation typically provides an R-value between 3 and 8. There is no single universal R-value; the optimal choice depends on your climate zone. Colder climates require a much higher R-value than warmer ones to maintain energy efficiency, keep the home warm in winter and cool in summer, and manage costs.

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.

Yes, energy-efficient options such as LEDs and solar-powered lights are available. These alternatives consume less electricity, resulting in lower utility costs. They are also more environmentally friendly due to their reduced carbon footprint and longer lifespan.
