I conduct energy audit tests for homes, whether they are colonial or brand new construction. I can recommend you various forms of weathersealant, thermal wrappings, and storm window techniques, saving you thousands in the form of long-term heat insulation tech-forward solutions.

"Ira was cordial and professional. He has practical experience and knowledge of residential energy audits. He was able to provide useful suggestions but not definitive solutions to issues. That may have been due to inaccessible interior walls. I am frustrated that a full written report that had been promised still has not been produced six weeks later."

"I hired Eco Green because I know people that have used them with no complaints. They were on the ball with everything. Fast, informative and ready to help. I had a hose break free from my washer and it flooded my office with 2 inches of water, the unit below us and the 3 floors below them. Within hours their team was in my unit, the water was up, the dehumidifier and industrial fans were running. Hours later, things were dry to the touch. By the next day, the floors didn't squish. We have no mold, no funny odors and they were able to save my wood floors by acting so quickly. If you value massive experience and the right tools for the job, Eco Green is your last call.

"My husband and I are first time home buyers and we thoroughly did our research before choosing a home inspector. We are more than pleased with Igor's professionalism and quality of work. He took his time with us and explained everything. Most importantly he gave us pointers on how to maintain our house after we purchase it. Igor is extremely knowledgable and thorough in everything that he does. In fact our real estate agent thought he was great as well and now she recommends him to other clients as well! Defiantly go with Igor from Eagle Eye Inspections, you would not be disappointed!"

"After I called for an estimate, Joey came promptly and assessed our insulation needs. He took his time to explain everything and also gave valuable energy savings tips. We scheduled a date and he and his crew arrived on time and insulated our attic. Within a couple of hours they were done with a thorough clean up."

"Person who visited was very polite and noted that what I purchased was likely not something that would meet my expectations.  I wanted an energy audit, how my systems could be improved in home, lighting, heating, insulation and air conditioners.  What I got was a list of things they could work on and the price to do that work.  The work list in no way was considered an energy audit, rather it was a punch list of things I could do based on their visual inspection.  I did not have a comparison of work and benefit/savings calculation.  There was no checklist of inefficiencies and how that translated into energy losses. For example, multiple hi hat lights in house, they spoke about boxing and insulating a few, less than 10, when I have almost 90 in house.  Overall I was disappointed, the tech who came said the offering needed to be better presented prior to start of work."

Energy Efficiency Auditing FAQs, answered by experts

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.

The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency. 

A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

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.
