"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

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably. 

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.

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.

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.
