"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."

"I had reached out to Lumeco Energy in order to take advantage of the Home Performance with Energy Star program rebates that Pepco offers their customers. After my initial energy audit with Lumeco, they provided me with a scope of work for new insulation, a new heat pump, and a new water heater (all rebate eligible). The cost was very competitive and the workers who came for the install were quick, clean, and incredibly polite. I've felt a noticeable increase in my home's comfort level since the work was completed and I'm very happy with my results."

"Very professional. Fully explained the process before starting and showed photos of the areas that needed insulation in my home. Before and after photos. Used energy company rebates to reduce my out of pocket expenses and did follow up evaluation. I saw the change in my energy bill! Thanks!"

"Atlas Home Energy Solution performed an energy audit for my home, followed by various insulation and weather-proofing tasks. Three other companies gave me estimates much higher for a work smaller in scope. Atlas estimate was lower for a more extensive work, and when combined with the rebate from BGE, turned out to be a highly reasonable deal. The employees were pleasant, courteous, and performed every task to perfection. I highly recommend them for any home energy issues"

Energy Efficiency Auditing FAQs, answered by experts

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.

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.

Smart glass doesn’t use a lot of electricity, and you can expect a standard window to add between $1 and $2 per year to your electric bills. Smart glass is proof that energy-efficient windows work. Although your smart windows may consume a little energy to operate, they can save enough energy to offset the costs. If you’re concerned about the minimal bump to your electricity consumption, you can opt for smart tint, which doesn’t require electricity to work.

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.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.
