"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."

"It is with sincere enthusiasm and pleasure that we express our deep satisfaction with the renovation of a large part of our home by Hunter Construction Company. We worked hand in hand with Mr. Brad Holbert, the owner. He had a craftsman's view of exactly what was needed by way of design to have the renovation fit in perfect accord with our beautiful, old home. He was fast, efficient, and has an amazing eye for detail.
Ours was a large project but he kept control of all facets of construction and finished on time. We found Mr.Holbert to very pleasant and trustworthy, and anyone would do well to place their project in his Company's very capable hands.

Energy Efficiency Auditing questions, answered by experts

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

Yes, energy-efficient options such as LEDs and solar-powered lights are available. These alternatives consume less electricity, resulting in lower utility costs. They are also more environmentally friendly due to their reduced carbon footprint and longer lifespan.

A home energy audit costs about $420 on average, with prices ranging from $100 to $2,250 or more. The final cost depends on factors like your home's size, location, the thoroughness of the audit, and the specific tests performed. A basic Level 1 walk-through inspection typically costs between $150 and $200, while a comprehensive Level 3 audit with detailed testing and a report costs around $900. Homeowners may be able to use the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit to cover up to $150 of the audit cost.

Costs for common individual tests include:

  • Blower door test: $350

  • Duct testing: $100

  • HERS test: $375

  • HERS certification: $200

  • Infrared imaging: $200

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

A whole-house humidifier can positively impact energy consumption by improving heating efficiency. During colder months, humidified air feels warmer, which allows you to lower your thermostat without sacrificing comfort. This adjustment can lead to significant energy savings as your heating system works more efficiently. However, it's important to use the humidifier judiciously, as excessive humidity could potentially strain your cooling system in warmer months.
