"My loft above my garage was humid and a bit uncomfortable from what I was expecting. I’ve watched enough home repair shows and understand air flow enough to know it would never be perfect, but something was off because of the humidity issues. Mike came in and did an inspection, confirming that there was a lot of room for improvement in the garage ceiling. The heat camera was showing that there was a lot of heat transfer happening in the loft, foot prints (from boots) leaving heat transfer marks which is unusual and recommended dense insulation pack to fill the void. I sat on it for a few weeks, called and scheduled for the 17th, but got in early due to an opening. It took several hours to complete the work, and the folks said it had 5” bat insulation but a 17” void, which confirmed Mike’s original thought that there was a gap between the insulation and the loft floor which was carrying the heat from the outside into the floor."

"They took my money and gave excuses about my roof access not being large enough to hoist the air compressor to the roof so instead of making a way they kept my money and stop responding, after numerous attempts to get in touch. They are out to take advantage of women. "

Energy Efficiency Auditing questions, answered by experts

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.

A whole-home humidifier can impact your energy bill positively. In colder months, humidified air feels warmer, allowing you to lower your thermostat without sacrificing comfort. This can lead to energy savings as your heating system works more efficiently. However, it's crucial to use the humidifier judiciously to avoid excessive humidity, which might strain your cooling system in warmer months.

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. 

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably. 

A couple of the best ways to find a reputable energy auditor is by determining whether they are HEP-certified by the Building Performance Institute (BPI). This certification will help you narrow down your list of professionals to the most qualified pros with the most relevant experience. 

You can also choose from the Department of Energy’s certified list of energy auditors or Angi’s contractor licensing tool to find pros in your area.
