We were extremely fortunate to have found Bob Nelson and his firm Ener G. Bob fully explained the home energy audit, documented his evaluation, provided energy solutions and costs, and recorded before and after test results. By encapsulating the crawl space, adding insulation to the attic, and upgrading ventilation fans, Bob improved moisture and temperature control, reduced air leakage, and enhanced air quality in our 2-1/2 story, all-electric home. Our energy consumption decreased by 30-40%. Bob also initiated and finalized the paperwork to receive utility incentive rebates which saved us thousands! Bob and his assistant Patrick, bring a friendly and superbly competent dynamic to the work. We highly endorse and recommend this team.
Description of Work: We requested a home energy audit to determine best solutions for air quality and temperature control in our recently purchased home. Priority solutions included crawl space encapsulation and improving insulation to the attic.

The folks from Ener G were easy to work with. They were able to schedule a home energy audit just a few days after I called. They performed the audit, gave us the recommendations, and returned after we had some insulation work done. They rechecked everything and submitted the forms necessary for our rebate. Approximately 6 weeks later, we received the rebate from our energy provider. Overall, I was very satisfied with their service.
Description of Work: Ener G conducted a home energy audit in order for me to qualify for an energy rebate from our local energy provider.

Bob and Patrick were professional and very helpful throughout the whole process, from the energy audit, to the quote, to the clean-up. Bob was quick to respond to e-mail questions. We received our BGE rebate on time. I'd definitely hire them again.
Description of Work: EnerG performed the BGE Energy Audit. We were happy with their quote, hired them for the energy efficiency work. They sealed air leakage in various areas of the house and insulated our attic. They also provided energy efficient light bulbs and made sure we received the BGE energy efficiency rebate ($2000).

Bob was great, very thorough and took the time to explain everything he was doing and the results. He also provided us an estimate to have the changes done to improve our efficiency. Ultimately we opted against having the work done because we decided to either sell or rent the townhouse and didn't want to invest that much more money into it. Had we intended on staying we would have definitely had the work performed by Bob and his organization.
Description of Work: Had an energy efficiency report done on our townhouse.

Their work was fantastic. They were very knowledgeable and reasonably priced. They were reputable. They will answer a thousand questions for you as you go through the process. They are great with dogs. They were very responsive. We plan to use them again. They laid out the plan in a way of what they would recommend to do first and then after so that we can continue to improve our energy efficiency.
Description of Work: They did an energy assessment. They then did some of the work to fix some of the issues in the house.

I have a large home that seemed to have trouble heating in the coldest months of the winter. A friend recommended Bob Nelson of Ener-G. I contacted Bob and in our first phone conversation I he had already begun diagnosing the problems of my home. Bob also explained the various options for improving my homes energy performance and best of all, he explained all the available tax rebates that were in effect that I could benefit from. In fact, the cost of the service I received from Bob was $450, but Bob utilized a rebate program from my utility company that paid $300 to Ener-G directly. Therefore I didn't have to fill out any forms or wait for a rebate check. Bob and I scheduled his visit and he came out that week. He spent several hours inspecting every floor of the house. He also performed a blower door test which ultimately tells you how well sealed your home is. It didn't take long for Bob to figure out that the leakage of heat was through an attic door. And it was a massive leak. I suspected the door may be leaking but Bob put it in to perspective by explaining how the blower door test works and how he was testing different areas of the home. It was quite the eye opener. Bob has since provided me with a detailed 24 page report on my homes performance and he recommended the best solutions to the problem. I have already taken steps to secure the seal of the leaking attic door and I intend to contract with Bob again to perform additional energy upgrades.
Description of Work: Ener-G performed a Home energy audit including an extensive visual inspection, blower door test, CO test, ventilation flow inspection, gas leak inspection, and I'm sure there were more that I don't recall.
