Energy Efficiency Auditing FAQs, answered by experts

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

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.

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.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.
