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.

Costs depend on pipe length, accessibility, and whether additional services are required.

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.

Dehumidifiers typically use 300 to 700 watts of electricity per hour, whereas portable dehumidifiers use about 40 watts per hour. The exact amount of electricity your dehumidifier will generate depends on its capacity and energy efficiency. Generally, higher-capacity dehumidifiers generate more electricity than lower-capacity units, but they also usually have better energy efficiency over the long run.
