"Edge Energy has installed solar power system on three houses that I own. In each case, they did an outstanding job. Their crew is experienced and work very hard. They were very careful with my property and involved me in decision making when options were available. If you want the best, go with Edge Energy and SunPower."

"Danny treated me like an old friend with helpful and timely service. It was refreshing. He inspected the unit, found a failed capacitor caused by an add-on Michael and Sons installed last inspection. Danny replaced the failed part, removed the add-on, and I was back in business in less than 30 minutes. I have a new HVAC provider!"

"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."

Energy Efficiency Auditing questions, answered by experts

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.

Expert installation optimizes insulation properties, cutting energy costs and enhancing home comfort year-round.

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.

DIY is possible with basic tools. Professional audits provide comprehensive assessments and tailored recommendations.
