"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."

"Jiri Svoboda was recommended to me from Ryland Home Builders in 2007 when I needed to enclose a large doorway with French doors to create an office. He did a magnificent job! He is a master in carpentry and drywall. Since that time, he has completed the following tasks for me: Inspected my second home before I purchased it in 2012 and his inspection was on point. At that time, he gave me an estimate of all the work I needed completed so I knew exactly what I was getting into. Thereafter, the added benefit was that he did most of the remodeling. He added a closet to an unused room and matched the crown molding and doors to create a forth bedroom that fits seamlessly into my home; He removed 2400 square feet of popcorn ceilings and left them flawless; Removed a wall between the breakfast room and the family room creating a great room; Built solid wooden shelving in the entire rear of the two-car garage and a ramp into the shed; I highly recommend Jiri for home inspection and any needs regarding carpentry and home improvement. He is professional, respectful of your home and cleans up perfectly after the job."

Energy Efficiency Auditing FAQs, answered by experts

Yes, with features like LED lighting and variable speed controls for efficiency.

Audits typically take 2-4 hours, depending on the property size and energy systems.

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.

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.

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.
