"Scheduling an appointment for my home energy audit was easy. They had plenty of available times within the next week so that was great. They arrived on time and got right to work. I would hire them again."

"Had issues with my furnace not throwing hot air. They got there the next day after I called them and told me it was a simple fix replacing the igniter. Been working ever since and would definitely call them again for any HAVC problems for sure."

"Jim did a terrific job on the floor. The project was complicated with lots of crazy angles and levels. Jim's expertise really shined for this project. He was very detailed oriented and a pleasure to have in my house. I forgot about a drain that a hole needed to be cut for. Jim drove over an hour back to my house to help me out and didn't even charge me for it. What a great professional! Please consider using him."

Energy Efficiency Auditing questions, answered by experts

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.

To find a reputable home energy auditor, start by researching local companies that offer the service and check their reviews, methods, and certifications. The most reputable professionals are often Home Energy Professional (HEP)-certified by the Building Performance Institute (BPI). You can also consult the Department of Energy’s certified list of energy auditors or use a state licensing tool to review local guidelines and ensure you are hiring a certified professional for your area.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

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.

Dehumidifiers typically use 300 to 700 watts of electricity per hour, whereas portable dehumidifiers use about 40 watts per hour. The exact amount of electricity your dehumidifier will generate depends on its capacity and energy efficiency. Generally, higher-capacity dehumidifiers generate more electricity than lower-capacity units, but they also usually have better energy efficiency over the long run.
