"Technician did not impress me as being very knowledgeable. He arrived in a Mr. Rooter truck so I guess he was more about drains and sewers than plumbing and heating. When he arrived, my wife showed him the Angie's list coupon for 10% off and he said "No problem". The extrol tank he installed on the hot water heater was twice as big as the one removed and it is sitting dangerously close to the exhaust stack. I will have to replace this when I get a chance! After the technician left, we noticed he had NOT given us the 10% off so we called D. Rohde. We were told it would be taken care of as soon as she reached someone in the invoicing group. We have called more than 4 times and keep getting the same "pass the buck" story and never received our 10% off! What a joke! I guess I will start using Home Advisor instead of Angie's list!!! In addition, after the technician left, we had no hot water. It turns out the pilot light was out. I was able to reset it but was away and my daughter who lives there had no hot water for several days until I returned to check it out."

"Dan and Josh were incredible. Not only were they both friendly and extremely knowledgeable, but the were early on the day the work was to be done. They explained exactly what they were doing.

"I made the mistake of selecting this contractor when NYSERDA accepted me for the Empower program in September 2024. Corey assured me they could act quickly. The audit was completed quickly, but seven months later, they have not done any work. Corey is a great sales guy, but the problem seems to be a complete breakdown between sales and delivery. In January, I spoke with John, who delivers the services, and we had a plan to move forward; however, he has not submitted the necessary paperwork to NYSERDA. He has not returned my calls, and Corey is wringing his hands in frustration. I would advise against using this contractor; the business is poorly run and fails to keep its promises. "

FAQs for energy efficiency auditing projects in Cornwall, NY
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.

HERS test: $375

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.
