"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, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.

Heat pumps transfer existing heat instead of generating it, using less energy. Compared to baseboard heaters, they can reduce heating costs by up to 50% and provide efficient cooling, lowering electricity bills and carbon footprint.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

Services by electricians can quickly get expensive, but there are a few ways you can save money in the process:

  • Bundle multiple jobs done at the same time to save on trip fees or flat fees for individual projects.

  • Get at least three quotes for service to find the best deal.

  • Buy fixtures, switches, outlets, and other materials beforehand to avoid product markup.

  • If you feel comfortable with it, have an apprentice or journeyman complete the work under the supervision of a master electrician. These electricians in training tend to charge less per project.

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.
