"If you are looking for affordability, dependability and quality work, then you can’t go wrong with Benge Electric. Harold and his team were great! They are flexible and easy to work with and take an honest and direct approach to their services and customer interactions. I was new to the area and found Harold on Angie’s List on the first try. I will definitely use their services again as I trust Benge Electric and had such a great first experience on a very large project on an older home that we recently purchase. Great job Benge Electric!"

"The owner called me very quickly after I put in a request on Angi and emailed a detailed and very reasonable estimate that same evening. He texted me the next day to make sure I got the estimate and I was able to talk to him about the work that day. While I have decided to put off the work for a while, I would definitely consider using his company for the work as he has provided excellent customer service so far."

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.

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills.

All are worthy causes.

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.
