"They did a complete home energy audit and gave me an itemized estimate so I could choose what aspects I wanted done. I chose to do everything they recommended. They removed old insulation and put in insulation up to 49R, removed mold and corrected venting for a bath fan that had not been properly vented to the out of doors. And a lot more. I was very pleased with their work. And they were FUN to work with and I learned a lot."

"The whole process was professional. From the initial call to completion of the project they were clear on what needed to be done and followed through with what they said they would do. They even worked on one small area that they weren't required too. Although no mold was present in the area there had been a little water damage there so they cleaned and sealed it to make sure. Their pricing was in the middle of the estimates I received but I decided to go with them after reading some reviews as well as the professional attitude they exhibited toward the estimate.

"I initially purchased the home energy audit from BPI in November.  There was a bit of time that lapsed after the initial contact and then a crazy game of phone tag for a matter of weeks.  As it turned out, John was dealing with some health issues at the time that have not been resolved with surgery.  When he came to our home to conduct the energy audit, he was definitely still on the mend.  With that being said, he was professional, helpful and thorough.  We definitely have a better idea of what needs to be completed to improve the energy performance of our home.

Energy Efficiency Auditing FAQs, answered by experts

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.

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

Services by electricians can quickly get expensive, but there are a few ways you can save money in the process:

  • Bundle multiple jobs done at the same time to save on trip fees or flat fees for individual projects.

  • Get at least three quotes for service to find the best deal.

  • Buy fixtures, switches, outlets, and other materials beforehand to avoid product markup.

  • If you feel comfortable with it, have an apprentice or journeyman complete the work under the supervision of a master electrician. These electricians in training tend to charge less per project.

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.
