"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!

"Was able to come within the hour verses the competitor who was squeezing me in at 4:00.  (Called at 10 am)  Arrived in time and immediately identified the problem  with the doorbell and then fixed the kitchen light all in one hour.  (and I had a coupon from the Angie's list book)  Great! "

"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 questions, answered by experts

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.

A good SEER rating for an HVAC system is typically between 15 and 20. However, minimum requirements vary by location; HVAC systems in northern states must have at least a 14 SEER rating, while those in southern states need a minimum of 15. For the highest possible efficiency, look for units with a SEER rating of 21 or higher. It's important to remember that a SEER rating represents the maximum efficiency a unit can achieve, not the level at which it will operate at all times.

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably. 

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.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.
