"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!"

"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 questions, answered by experts

Typically, triple-pane windows made with krypton gas filling are the most energy efficient. A window’s frame, glass, design, and installation all affect its energy efficiency. These windows, in particular, are designed highly effectively in terms of their ability to insulate.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

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.

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.

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.
