Energy Efficiency Auditing questions, answered by experts

An average, 400-square-foot electric heated driveways consume approximately $3 per hour in terms of electricity. The price may slightly fluctuate depending on your local energy cost. A simple formula to calculate your heated driveway’s total wattage consumption is by multiplying the square footage by 50 watts and then dividing it by 1,000 to get the kilowatt number. Multiply that with your local energy cost per hour and there you have the hourly operating cost.

A good SEER rating is between 15 and 20. However, if you want the best possible efficiency, look for HVAC units with a SEER rating higher than 21.

While parts of the appraisal are out of your control, there are some things you can do to potentially raise the home’s value. You can make necessary repairs and upgrades before the appraiser visits—an appraiser can only value what is currently part of the home, not its potential. You can also provide the appraiser with the cost of recent upgrades. The appraiser will likely increase the value of your home by about 50% or more of what you paid for those improvements.
