"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

"That was fine. It was cool. hey came and did the energy scan and they pitched their products which was way out of price range. It was good to find out where we had our little heat and chronic leak. They did it for the $39 big deal cost. The price was really good. If I needed another energy scan, I would use them in the future. I would consider them in the future. They're expensive for what they actually do but the energy scan was a really good deal."

Energy Efficiency Auditing questions, answered by experts

Yes, with features like LED lighting and variable speed controls for efficiency.

Fireplaces can theoretically help you save on heating bills if you lower the temperature throughout the rest of your home and heat only a single room that you occupy using the fireplace. However, in most cases, homeowners won’t save any money on heating bills. Gas and electric fireplace inserts could actually lead to a spike in your respective energy bills if you use them frequently, and if you don’t keep up with chimney maintenance and repairs, your traditional masonry fireplace could actually be a source of heat loss in the winter.

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. 

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, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.
