"I couldn't say enough good about Wise and their folks - they replaced my furnace and hot water heater, as well as did all the insulation in my basement, walls and attic entrance. The staff was knowledgeable, friendly, professional, respectful and left my home spotless. Seriously, I've never had as positive experience as I did with these folks. I *highly* recommend them!"

"Michelle was great. Very detail oriented, knowledge, and gave great suggestions during the post-purchase inspection. She allowed us to accompany her during the inspection and answered any and all questions we had, very approachable. She spent almost two hours with us and gave a great, 22 page report with photos afterwards. Good communication pre and post inspection. Highly recommend, I have already sent her info to a friend who is looking for an inspection."

Energy Efficiency Auditing questions, 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.

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

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.

Dryers are designed to use as little electricity as possible, but power is still required to run the motor that turns the drum and to heat an element that pumps hot air. Eco devices are available and may lead to cost savings in the long term, but you should run the figures before committing to an eco-friendly device as they are often much more expensive to purchase.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.
