"Very impressed from start to finish. First a young lady came out to do an inspection, then the consultant came out and showed us the results explained what we could do to make our home more energy efficient, things we could ourselves services they offered how much it was going to cost. The installers were very polite and respectful of our home and did a thorough clean up when they left. Our consultant was and project manager kept us informed of what and when the installation would occur. I would recommend them to anyone whoâ s interested in wanting to have their home more energy efficient"

"I called to set up a free consultation and was promptly met at the agreed upon time. We discussed my desires and how to achieve my project goals. I was given a quote and agreed upon the price for the garage work to be done the following week when I was free. The spray foam and "drill and fill" have been awesome! I have a 24K BTU AC unit in the garage that was unable to keep the temps low as there was so much heat in the garage all day. After the insulation was done it can hold the temps at 70F in the garage while barely turning on during the day. The attic above the garage tops out at 85F when it was over 110F outside, just amazing. We had them do a home energy audit and found that there were plenty of leaky areas in the attic and the insulation was 15 years old and about an R-10 level. It needed some serious work so we agreed to have it topped off with new fiberglass insulation. The guys came out and did and amazing job bringing me up to R-39 as well as keeping the house very clean while doing it. On both days they cleaned up after themselves and took great care of my house. I would wholeheartedly recommend them to anyone that could use more insulation!"

Energy Efficiency Auditing questions, answered by experts

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.

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.

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.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.
