"Wonderful, it was a very quick and easy process. Brian talked us through it and in no time we had a 3KW system mounted on a frame in the garden and the invertor installed in the basement. Brian talked us through working with our power company to get the system checked and approved and we now get credits from the power company for power we provide to the grid. In addition we are set up to get Solar Renewable Energy Credits (SRECs) payments for providing clean energy. We also got a free Energy Audit which helped locate some problems areas we were able to fix. The system has basically cut our energy costs in half. I have hesitation in recommending them to anyone interested in solar energy."

"It went great.  He showed up on time and was professional while working 3 to 4 hours.  Invoice matched the quote, even though it took him longer than he anticipated.  He didn't charge for the extra hour which was cool.  We will use him in the future for sure.  We have now started a Sound Advice To Do List for future visits.  I see having him come out once a year to update things and give us an idea of what's new.  Very pleased!

Cherokee Mechanical did an exceptional job on this service call.  They were quick to get back to me after I purchased the voucher (which, by the way, was the cheapest price of any such check-up that I have seen) and scheduled a date and time which ideally fit my own schedule and was for only a few days after I purchased the voucher.  Dean presented as very professional and performed his tasks with alacrity and ease.  He not only replaced my air filters -- which was a big help as I am still using a crutch after ankle surgery -- but also spent time explaining to me the most efficient filters to get (which, by the way, are not the more expensive ones) thus offering me another way to save money.  I definitely plan on using this firm in the future and would highly recommend them to anyone in need of HVAC service or repairs.

"Bill was very professional. They installed a roof for me in 2013 and I knew then I would use them again.  They are very professional and courteous.  They explained everything in detail and followed-up. They also did a great job cleaning up after the work was completed. Most recently, I have used BTR for repair and "handyman" work. I had the same experience with them.  I would use them again.

Energy Efficiency Auditing FAQs, answered by experts

When installing a new furnace, it's a good time to consider other projects that can enhance your home's energy efficiency. A great first step is to get a home energy audit, which will identify areas for improvement. Common recommendations include sealing or replacing windows and adding insulation to the attic. These upgrades can help you save money on monthly utility costs. You might also consider installing a smart thermostat to make heating your home more convenient and efficient.

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal. Also, sometimes bundling your auto and homeowner’s insurance will get you a discount on both. Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.

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 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.

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.
