"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

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

No, it isn’t necessary to have energy-efficient windows. However, if you care about your energy bill and making your windows more energy efficient, fixing any heat, UV, or air transfer issues is an excellent way to lower your bills and keep your house cooler in the summer and warmer in the winter.

Dryers are designed to use as little electricity as possible, but power is still required to run the motor that turns the drum and to heat an element that pumps hot air. Eco devices are available and may lead to cost savings in the long term, but you should run the figures before committing to an eco-friendly device as they are often much more expensive to purchase.

When combined with a substantial solar system, if you have enough Powerwalls, you could go off-grid and be energy independent. But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods. One Powerwall is able to power an average-sized home's emergency circuits, lights, and outlets. To power large appliances, you likely need two or three Powerwalls.

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
