"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 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."

"Dr. Energy Saver was very thorough in finding the comfort and energy issues in one of my customers homes. They showed the customer exactly what was going on, why they had any issues, and how they were going to solve them. They provided a prioritized list of solutions for them too so they could pick and choose the importance to the homeowner. All work was done in a timely fashion, was clean, and fixed their issues."

"Amazing. Ronnie was super professional, very diligent, explained everything, meticulous, and cleaned up very thoroughly afterwards. We have a particularly difficult attic, yet the electrician navigated it it deftly. We would definitely hire this company again, and are already planning our next job."

"I wanted to use a locally owned electrical company, if possible, and was very happy to see the number of very good reviews for Evergreen Electric on Angie's list. I called early in the morning and Evergreen Electric was able to work me into their schedule on the same day which I was very grateful for due to the safety concerns of not having properly working smoke alarms in my house. Thad Sale and his assistant showed up at the appointed time and changed out the six smoke alarms very quickly. They also changed out one I had forgotten about (basement) while they were at my house. Also, Thad Sale gave me an estimate for a potential new electric project which seemed very reasonable. Evergreen was very professional and answered all my questions. The work was done very quickly and I feel much safer having properly working smoke alarms in my house. I would definitely call Evergreen Electric for my next electrical project.

"Was thoroughly impressed by H and F. I needed to replace an electric heat pump that was 30+ years old and on the verge of failing, and had a pretty good idea of what I wanted based on some research and quotes I had from other HVAC companies. Not only is H and F highly rated on this site, they also came in with lowest quote (and better warranties) for a 15 SEER Carrier with humidifier. Installation went smoothly, Michael and Dexter were consummate professionals and had my new system up and running in about five hours. I would highly recommend them to anyone in the North Virginia area. High quality and reasonable price. Will definitely use them for follow-on maintenance."

"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 questions, answered by experts

Installing weather stripping or upgrading to insulated panels can improve efficiency.

Audits typically take 2-4 hours, depending on the property size and energy systems.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

Typically, triple-pane windows made with krypton gas filling are the most energy efficient. A window’s frame, glass, design, and installation all affect its energy efficiency. These windows, in particular, are designed highly effectively in terms of their ability to insulate.
