"We hired Edge Energy to do a full house remodel (3,000 sq. ft.,two floors, kitchen, living room, dining room, family room, breakfast space, four bedrooms, two full baths and a powder room, laundry room). This is a little outside their normal scope but we really liked the company owner, Jason Dispenza and he set up a favorable pricing schedule that didn't include some of the exorbitant management fees we have seen with other contractors. They started with an energy audit which helped to determine some of the aspects of the systems upgrades we would need. We changed the room configuration on both floors, replaced major systems (water heater, HVAC,electrical, etc.) replaced windows and put in new window openings, installed support beams, replaced the roof, insulation, electrical upgrade and lighting, replaced much of the hardwood flooring, drywall, paint and added a new front entry with a new porch. It was a major job which we lived through for months with the exception of about two weeks when the drywall work was being done. Our living there caused Edge some additional work, but they were considerate of protecting what remained in the house, and making the space as livable as possible. The result is beautiful and we probably have one of the most energy efficient homes in our area of Maryland. The Edge crew was great to work with, very considerate and careful to not disrupt our life more than necessary. Mike Hogan, the project manager was very good to work with, attentive to concerns and very responsive to suggestions. During many weeks we were talking daily. Most subs were very good as well- the HVAC, roofing and drywall guys were great. Our only concerns were with the plumber who delayed the project considerably and the final cost of the project was higher than the estimate we had originally received. I would highly recommend Edge Energy for their work and their customer responsiveness. They are technically highly competent and are very good people to work with."

"Atlas Home Energy performed an energy audit in my home, and based on the findings corrected all issues over a four day course. Their workmanship is flawless and their employees are pleasant and courteous. The bulk of their charge was reimbursed by BGE and my energy cost has declined. I recommend them highly"

"I highly recommend Lumeco Energy. They did my home energy audit and gave me some good recommendations. We chose to air seal our attic and add more insulation. They were able to get me some rebates from BGE so the pricing was discounted."

"Have a problem with cold basement and hired Home Energy Saving Solutions, LLC to do home energy audit. Energy consultant Mohammed El-Ghoul came on time and after short inspection suggested that we do need more specific HVAC audit, not whole home energy audit. Mohammed suggested a company which can do this, also made some very useful suggestions, and checked couple of things for free. We were not charged for service despite fact that Mohammed spent almost an hour at our home and provided useful advices. Very professional and honest service and I strongly recommend Home Energy Saving Solutions, LLC and especially energy consultant Mohammed El-Ghoul!"
An energy audit costs about $420 on average, ranging from $100 to $2,250, depending on the size of your home, property, location, and the tests the auditor needs to perform. Keep in mind that the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit covers up to $150 of home energy audit costs. Common energy audit tests include:
Blower door test: $350
Duct testing: $100
HERS test: $375
HERS certification: $200
Infrared imaging: $200
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.
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.
The three levels of home energy audits include:
Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.
Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.
Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
To find a reputable energy auditor, find a local company that offers energy audit services. Research the company’s reviews, methods, and certifications to find a reliable professional in your area. The most reputable energy audit companies are HEP-certified by the Building Performance Institute (BPI). Be sure to check our state licensing tool to review the local energy auditor guidelines to ensure you’re hiring a certified professional.
