"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

Thankfully, LED lights use less electricity than incandescent lights, meaning you won’t spend as much on utility bills by using these light strips. Each 5-meter LED light strip will cost about $3 per year on your energy bill.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.

Some types of electric fireplaces use more electricity than others. Models that produce 1,500 watts will have more of an effect on your heating bill than 750-watt models. 

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

Heat pumps transfer existing heat instead of generating it, using less energy. Compared to baseboard heaters, they can reduce heating costs by up to 50% and provide efficient cooling, lowering electricity bills and carbon footprint.
