"Edge Energy did an energy audit for us, then sealed the house, installed a new roof with excellent insulation, and an ERV fan to ensure fresh air. They were a delight to work with throughout, very friendly and professional. We needed some follow up work due to quirks in the house, not bad work by Edge, and they did it promptly and without charge. I couldn't recommend them more highly."

"I had a full house evaluation. Elite Thermal was able to use that to get me a significant discount. They came and did the service in in one day and then returned a few weeks afterwards to find tune and the leaks that were identified on the follow up blower test. They changed the wrong exhaust fan and then did the right one at no additional charge. I would definitely work with them again. Actually, they have done an evaluation and an estimate on my second home and I expect to have them start soon."

"I highly recommend Lumeco Energy. They did my home energy audit and gave me some good recommendations. We chose to air seal our attic and add more insulation. They were able to get me some rebates from BGE so the pricing was discounted."

"Very professional. Fully explained the process before starting and showed photos of the areas that needed insulation in my home. Before and after photos. Used energy company rebates to reduce my out of pocket expenses and did follow up evaluation. I saw the change in my energy bill! Thanks!"

Energy Efficiency Auditing FAQs, answered by experts

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. 

Attic and whole-house fans improve a home's energy efficiency and comfort. They ventilate hot air from the attic, which reduces peak cooling loads, lowers reliance on air conditioning, and decreases indoor temperatures. This improved air circulation and expedited heat exit helps lower cooling costs, balance moisture levels, and enhance overall natural airflow, contributing to the efficient operation of other home equipment.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

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. 

Some types of electric fireplaces use more electricity than others. Models that produce 1,500 watts will have more of an effect on your heating bill than 750-watt models. 

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.
