After Hurricanes Irma and Maria hit in 2017, I supervised the rebuild of the property tougher, stronger, and better than before – complete with a half-megawatt backup generator.\n\nMy knowledge, training, and experience allow me to bring a get-it-done-right attitude to every home inspection. I look forward to putting that knowledge and experience to work for you! \n828-760-7716

"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."

"I got a coupon/deal on Angie's List.  It was for Energy Audit + Attic Insulation
The guys that came to insulate my attic did an excellent job. I believe the person's name that did the job is Peter. Great guy and he knew what he was doing and it was evident that he wanted to do a great job, which is rare to find these days.
However, they never did the energy audit as the device was broken and they had to get it fixed. They showed up on a cold rainy day and the weather was not  favourable as the outside temperature was same as the inside and the energy audit will not be effective. 
I have not called them back for energy audit even though its paid for as I have some renovations work going on. I hope they will come and complete the energy audit once I am ready.
Overall A++. I highly recommend Fresh Air!

"If you are looking for someone to install home theater--don't even bother looking anywhere else. Robert's prices were competitive, and he did an absolutely amazing job for us. He even worked overtime to make sure he was finished within the timeframe we agreed upon, and he made sure everything was working perfectly and took the time to walk us through everything. I cannot recommend him highly enough--super nice guy who is very skilled, knowledgable and works tirelessly to make sure you're happy. There's not much more you can ask for in a service provider.

Energy Efficiency Auditing FAQs, answered by experts

Costs depend on pipe length, accessibility, and whether additional services are required.

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.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

A blower door test shouldn’t take more than an hour, and most can be completed in less than 30 minutes. Expect the test to take longer once you start searching for leaks with thermal imaging or want to include sealing such leaks in the time estimate. The test doesn’t take much time and can’t be rushed, but it will take longer in large homes or those with many air leaks.

Yes, most audits include a report with prioritized recommendations for improving energy efficiency. Confirm with your auditor.
