"Great people. They put down cloth to protect the floors from their boots. They tested the house before they started the work. They showed me results and explained them. They did the work, tested the house again and showed me the results again. BIG DIFFERENCE! They cleaned up everything afterwards, showed me and explained everything they had done and told me to call if I ever had any questions. Excellent!!"

"These guys were fantastic! Mike really knows his heat pumps and it showsâ he was always available via email when I had a question, he walked us through the entire process for applying for the state heat pump rebates, and we couldnâ t be happier with the system one year in. Because of our Initial positive experience with Mike, we also hired Energy Monster to do our solar panel installation. Top notch, LOCAL company!"

"Ryan did excellent work. He explained everything so I could understand it. In just a few hours he rewired my electric heating system in my duplex. For the first time since I moved here (14 months) my heat is completely off !! I would give him 10 stars if it was possible, but here I would give him 5 stars."

Energy Efficiency Auditing questions, answered by experts

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.

Yes, including optimizing settings and suggesting upgrades if needed.

Yes, barndominiums are energy-efficient as long as insulation professionals properly install quality insulation, windows, and doors. Utility bills for barndo living can be up to 50% lower than those for a traditional home.  Make your barndo more energy efficient by working with contractors and HVAC professionals to strategically place windows, doors, and heating/cooling systems. 

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.
