"I participated in Dominion's Energy Efficiency Rebate program, which NRG Masters (dba Northcoast Energy Masters) is a participating contractor. Of the three quotes received, NRG Masters and one other contractor were competitively priced. However that other contractor do not spray foam gaps in basement. NRG Master crew arrived on time on scheduled date, they properly sealed the attic entrance so the cellulose does not blow throughout the house and to keep my pets from going upstairs. Wall insulation was performed outside, where they removed the siding, blew in cellulose into the wall and ,closed the opening and reinstalled the removed siding. They spray foamed rim joists all around the basement perimeter and a big gap where the kitchen bumped out, such that one of my cats tend to climb into and where she cannot be reached. They insulated it and closed it with dry wall so my cat can no longer go in. The crew cleaned up the work areas, They vacuum the attic, and cleaned up the basement area, though they missed some of the small spray foam drippings, which were easily removed on the concrete ground, which I believed to be not an issue. A week later I opened the attic storage area, some of the cellulose blew in. I had to followed up multiple times with e-mails and phone calls to get a return call and schedule a follow up to fix the problem. Ray said the cellulose blowing in is from the gable vent, which may have been overstuffed with cellulose. A month later, the crew came back to clean up the cellulose. Months later, I followed up with another energy audit from Dominion's program. I learned the home energy efficiency for my house improved from 2800 (before the insulation work) CFM50 (blow door test) to 2100 as proposed by NRG Master. I, also, followed up with Dominion regarding the status of my rebate, and I learned that Ray did not submit the paper work required for the rebate. I followed up with multiple calls and e-mails. At the same time Dominion representatives also reached out to him. A few weeks later, I learned that Dominion did speak with Ray and he submitted the necessary paper work, and a month later, I did get my rebate check. The slow responsiveness received from NRG Master may be attributed to their busy schedule, I had to wait about one month and half before they could perform the work at my house, so it is understandable that arising issues and filing paper work can fall to the side, though not acceptable from a customer perspective."

"I had an Energy audit performed on my house. The equipment used during the audit and the knowledge of the auditor was good. However, the report was useless. I was employed as a Quality Manager / Quality Engineer for over 35 years and I have performed numerous audits. And without a doubt, the auditors should used a recorder to propely document the results of the audit. Some of the things that should be in th report are, the significant areas of heat loss in each room, (including loacation of the heat losses), potential savings for reducing the major area of heat loss, the temperature difference incoming outside air and room temperature."

"The owner of the company came out at the scheduled time and date and listened to what I wanted done. We walked through the house to actual see what the job would entail, he made some suggestions and explained his thoughts. Within 2 days I received a written quote with options for walls only , or plus ceiling (attic), and/ or crawl space. I picked the option I wanted and the work was scheduled. The work crew was polite, efficient, and left the house cleaned up. Also, the owner will submit the paperwork needed for a energy rebate. Great experience!"

"It went well with the workers arriving when expected and cleaning up when done. It took them 2 days. They did a great job and were cheaper than another one of our estimates.
We decided to get some insulation following a report from Dominion's Home Energy Audit Program called GoodCents which told us that our over 100 year old home had almost no insulation.
North Coast Insulation is a company recommended by Angie's List and one that often works with GoodCents. GoodCents came out after the insulation was installed and inspected it. We were told that the air leakage from the house had gone down 40%. We also will get over $1000 back from a rebate.

Energy Efficiency Auditing FAQs, answered by experts

Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.

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

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.
