"We contracted with Greene Solutions a couple of years ago to complete an energy audit and to map out a series energy saving projects to achieve desired energy efficiency and comfort goals for our 30 year old home. The last two projects were completed in September 2019. First vapor seal our partial basementâ s crawl space floor and walls and second to use the unique Aerosealï Technology to internally seal our gas furnace/air conditionâ s ductwork. Greene Solutionâ s four man team (Jason, Owen, Pearse and Harvey) arrived promptly at 8:30 am and began both projects. They worked very effectively and efficiently as a team to accomplish each project in a professional way always respecting our homeâ s interior and keeping us abreast of their progress. We are especially excited to have the Aerosealï Technology applied to our â leakyâ duct system as it has vastly improved the performance and efficiency of our Lennox furnace and air conditioning systems. Thank you Thomas and the Greene Solutions team for your excellence in developing our plan and in the completion of our latest projects. Well DONE !! Bob & Barbara Hammond Dublin, Ohio"

"Everything was really good including scheduling except for one of the breaker handles got broken while testing and they didn’t replace it.  This made the new electrical panel look used.  I would be worried about touching this part of it if there was water in the basement. He made it easy for me to understand what they were going to do and communication was good with them."

"Could not be more happy. Everything just went as well as it could have during this crazy COVID stuff. Windows went smooth, roof in a day and siding was a few days. Entire project start to finish was 8 days and the clean up was exceptionally well done. Did not even know they were here. Definitely recommend Bradford Xteriors to anyone needing things done. Jason, the owner is very wired at all time but none the less a great guy and now friend."

"The house was a lot warmer now and he did an excellent job. He guarantees his job. It was a reasonable price. He walks me through the process. He's a good guy. He called a week later and check if I was satisfied with the service. He came all the way from Columbus. It was an hour away from here and he came early. He did extra work for free. I would recommend him. He takes pride in his work and didn't take advantage of me."

Energy Efficiency Auditing FAQs, answered by experts

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

A blower door test shouldn’t take more than an hour, and most can be completed in less than 30 minutes. Expect the test to take longer once you start searching for leaks with thermal imaging or want to include sealing such leaks in the time estimate. The test doesn’t take much time and can’t be rushed, but it will take longer in large homes or those with many air leaks.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

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.

HVAC systems use the most household electricity. This major and essential system is responsible for heating and cooling your home all year round. Since they operate for a significant amount during the day, it consumes more energy than other appliances.
