"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."

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

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.

Homeowners may qualify for an HVAC tax credit if they install an ENERGY STAR®-certified HVAC system that exceeds the energy efficiency minimum standards:

  • Split-System AC: 16 SEER2

  • Packaged AC: 15.2 SEER2 and 11.5 EER2

  • Ducted Split Heat Pump: 15.2 SEER2, 7.8 HSPF2, and 11.7 EER2 

  • Packaged Heat Pump: 15.2 SEER2, 7.2 HSPF2, and 10.6 EER2

  • Mini-Split System: 16 SEER2, 9 HSPF2, and 12 EER2

You can claim up to 30% of the cost of the job, subject to maximums.

ENERGY STAR®-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR®-certified windows lower household energy bills by an average of 12% annually.

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.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.
