Energy Efficiency Auditing FAQs, answered by experts

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.

Keep the unit full but not overloaded, ensure door seals are tight, set correct temperatures, and avoid frequent door openings. Position the appliance away from heat sources for optimal performance.

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. 

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.

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.
