"Very Professional service! Mr Hoover is not your every day Insulation Installer, he is an Energy Performance Auditor. He makes sure the air in your Attic is conditioned and that your Ceiling is completely sealed before blowing in 20" of Insulation. If you need Insulation for your House this is the company to hire. I highly recommend them and will be doing a follow up review in a month comparing my Energy Savings!"

"Rep. checked entire system. He found several wires not connected properly and fixed this. He also made recommendations regarding the attachment of the panels to the rood that would provide more stability and leakproofing. The representative appeared to know what he was doing - much better than others, including the representative who was engaged by the roofer (who replaced our rood due to hail damage) to disconnect/connect the panels."

Energy Efficiency Auditing FAQs, answered by experts

HVAC systems use the most household electricity. This major and essential system is responsible for heating and cooling your home all year round. Since they operate for a significant amount during the day, it consumes more energy than other appliances. 

Smart glass doesn’t use a lot of electricity, and you can expect a standard window to add between $1 and $2 per year to your electric bills. Smart glass is proof that energy-efficient windows work. Although your smart windows may consume a little energy to operate, they can save enough energy to offset the costs. If you’re concerned about the minimal bump to your electricity consumption, you can opt for smart tint, which doesn’t require electricity to work.

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.

There are a couple of ways you can save on the cost of your home energy audit. First, find out if you qualify for programs like the Department of Energy’s Weatherization Assistance Program for low-income households. Next, check with your local utility company to find out if you qualify for any local rebate programs to offset the cost of this helpful service.

Yes, most audits include a report with prioritized recommendations for improving energy efficiency. Confirm with your auditor.
