"I reside in Dearborn and hired USA Insulation of SE Michigan. I am pleased to write that they did an excellent and thorough job. There was a couple of minor issues that were resolved immediately. The workers were kind and respectful. They cleaned up the mess. Other than the sign in the yard, you wouldn't have known they were here. It's been a month and I noticed that the outside noise has been reduced. The temperature in the home is better but with 100 degree temps outside it is difficult to judge. I have to wait for the first electric bill."

"I'm extremely satisfied with the work that was performed.From the first day that I got in contact with the company,I was assured that everything would be ok.Tom of R & L came to my building and assessed the situation and he immediately began to make calls to get things back in order for me.Because of the fire damage my building and contents were in bad shape.Tom was able to contact my insurance adjuster and before you know it there was all kinds of action going on in my building to get things back in order.I must say that I do now have a very professional and new looking building from the work done by R & L company.Of all the different people that Tom had to come and perform work on my building,they were all professional with very positive attitudes,and I felt comfortable with them being in my building.I will be recommending the services of R & L in the future,they are a great company and I love the work that they did for me.

Energy Efficiency Auditing FAQs, answered by experts

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.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.

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.
