Energy Efficiency Auditing questions, answered by experts

The extra insulation helps reduce energy costs by minimizing drafts and temperature exchange between indoors and outdoors.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

Gas fireplaces use either natural gas or propane—both of which will increase your energy expenses. On average, running a gas fireplace costs $400 to $640 per year; however, these costs can vary significantly depending on the fuel price in your area and the frequency of fireplace use. If you’re looking for a more energy-efficient option, consider switching to an electric fireplace.

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home.
