"My husband and I agree: Working with Voltaire Engineering was completely satisfying from beginning to end! All successful experiences start at the top, and this one was no exception. After we purchased a special deal through Angie's List, Director of Operations Dan Rosenbaum contacted us promptly and set up an appointment to visit our home. We instantly liked him; he is witty, smart and easy to talk to and just instinctively inspires confidence. He helped us to see past the obvious solutions to our various needs, and in each case we were glad we followed his advice. His electrician and painters were fabulous, too. They listened carefully to our needs and completed all tasks with true professionalism. In short, we were thrilled with every aspect of the project, including pricing. True to his company name, Dan is an enlightened professional whose problem solving approach to providing services is impressive. We loved having him and his team in our home. In fact, we have just compiled a list of additional projects and are hopeful that we can hire him again!"

"It went great. The initial price was a bit steep, but since I had other quotes, they were willing to negotiate. I dealt with Anthony as the project manager and Kevin and Ryan, who did the work. These guys were professional, always showed up early and they did a great job. Even when I goofed up a measurement on where I wanted a ceiling light placed; they fixed it at no cost. I couldn't be happier with the work they did. I had a full kitchen remodel as well as troubleshooting multiple 3-way lights in the house that were incorrectly wired."

"i was very impressed with the professionalism of the assessment and the comprehensiveness of the report. As followup they came and discussed the report and explained any questions. I submitted the report to the Governors Energy Office (GEO) for partial reimbursement (rebate) and will personally address air infiltration and other problem areas noted in the report. I would highly recommend Voltaire for home energy audits."

Energy Efficiency Auditing FAQs, answered by experts

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.

You'll likely need more than great home staging to sell your home. Now is a great time to get to work on the curb appeal of your home . Hire local exterior painters and landscapers to coat the exterior of your home and bring it new life with some sprucing up.

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.

Electric bills tend to be lower in spring and fall because people use less electricity during these seasons. Milder temperatures allow for less use of heating and cooling, unlike during winter and summer, which usually bring more extreme temperatures.

There are several signs that your house might have poor ventilation, including lingering odors, condensation on your windows, or mold and mildew. Your home may also feel stale and stuffy, or you might have trouble maintaining a comfortable temperature in your home. On top of that, you might develop allergy symptoms, such as sneezing, coughing, or headaches.
