We had some questions about some problems under the house. A man came out and explained to me what they could offer to try to solve those problems. They call it the doctor energy specialist or something, I don?t know. It?s about removing moisture and other things from under the house and making sure the ducts are properly attached and that they are insulated properly. That the house insulation is proper and they sealed most of the vents to keep the wet air from coming in. They put in a dehumidifier and all that stuff. They did a large amount of work. They put in a new moisture barrier and corrected some problems that we already paid somebody to do and they didn?t do. They even attached the dryer duct, which wasn?t attached and the air was going out all under the house. They were very very good. They did what they said. They took all the trash and everything they found out from under there. This whole experience has been a nightmare. Those people at GSM were super. The inspection he did not charge us for, but we put an amount down on the work they were going to start doing. It was excellent because he went under the house, he took pictures of all the things he was going to tell me about, and then he explained the different treatments that were available and the prices for those treatments. And what particular things they would correct. It was very clear and he was very good about answering my questions. He seemed very experienced.

"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!

"It was fine. While he was here I got an estimate for a new roof but decided not to use them.  They came out on the agreed upon time. They were responsive. He took measurements of the insulation and gave me an estimate of things to do to make it more energy efficient."

Energy Efficiency Auditing FAQs, answered by experts

Provide utility bills and clear access to all areas of the home, including the attic and basement.

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.

R-value measures an insulation material's thermal resistance, indicating its ability to resist heat transfer. A higher R-value signifies better insulation performance because the material is more effective at slowing heat flow. The R-value depends on the type, thickness, and density of the insulation material, such as fiberglass, foam, or cellulose. Each inch of insulation typically provides an R-value between 3 and 8. There is no single universal R-value; the optimal choice depends on your climate zone. Colder climates require a much higher R-value than warmer ones to maintain energy efficiency, keep the home warm in winter and cool in summer, and manage costs.

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.

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.
