"Heatmizer (Bob Frechette) did an energy audit on our 1970 mobile home we were about to remodel. We followed his recommendations and had them spray foam and insulate after we gutted it. He installed a Mitsubishi Heat Pump that heats, cools and dehumidifies our cozy, home. The energy audit helped us attain an efficient, healthy home! We highly recommend using Heatmizer to make your home as efficient aand healthy as it can be."

Expect the test to take longer once you start searching for leaks with thermal imaging or want to include sealing such leaks in the time estimate. The test doesn’t take much time and can’t be rushed, but it will take longer in large homes or those with many air leaks.

A whole-house humidifier can positively impact energy consumption by improving heating efficiency. During colder months, humidified air feels warmer, which allows you to lower your thermostat without sacrificing comfort. This adjustment can lead to significant energy savings as your heating system works more efficiently. However, it's important to use the humidifier judiciously, as excessive humidity could potentially strain your cooling system in warmer months.

Smart glass doesn’t use a lot of electricity, and you can expect a standard window to add between $1 and $2 per year to your electric bills. Smart glass is proof that energy-efficient windows work. Although your smart windows may consume a little energy to operate, they can save enough energy to offset the costs. If you’re concerned about the minimal bump to your electricity consumption, you can opt for smart tint, which doesn’t require electricity to work.

Yes, pros suggest units with high EER ratings for energy savings.

Yes, installing an attic fan can help lower your electric bill—particularly if you live in a hot and humid region.
