Meet Your Home Inspector - Hi there! I’m Dylan Osborne, North Carolina Licensed and InterNACHI Certified Professional Home Inspector – CPI. I hold a Degree in Applied Science; Architecture & Construction Technologies, and 25 years of experience in land surveying, commercial property maintenance, and general manager for a 10-building, 75-unit condo complex in the US Virgin Islands. 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

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

Yes, Tesla Powerwalls are worth the upfront costs, as you can recoup your investment within six to eight years. Plus, they provide peace of mind that you'll have power during a power outage, and, depending on the system you install, you can become energy-independent. While they may be more expensive than other solar power systems, they offer higher battery capacity and lifespan.

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

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.
