Energy Efficiency Auditing FAQs, answered by experts

DIY is possible with basic tools. Professional audits provide comprehensive assessments and tailored recommendations.

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.

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