Set the unit temperature at least 1 degree higher than it is currently to reduce costs. <a href="https://www.angi.com/articles/how-to-clean-your-window-unit-air-conditioner.htm">Keep the unit clean</a> for it to run efficiently. You may want to hire a <a href="https://www.angi.com/nearme/window-ac-repair/">window AC specialist near you</a> to inspect the unit once a year and keep it in tip-top shape.</p></div>

Can a dirty air filter cause a high electric bill?

• <div><p>Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the <a href="https://www.energy.gov/energysaver/maintaining-your-air-conditioner#:~:text=Replacing%20a%20dirty%2C%20clogged%20filter,in%20the%20air%20conditioner%20itself.">U.S. Department of Energy</a>, replacing dirty filters can save you between 5% and 15% in utility costs.</p></div>

Q: How much energy do motion-sensor lights save?

• <div><p>Motion-sensor lights use one watt while on standby and five watts while turned on. They&rsquo;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&rsquo;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.</p></div>

Q: Do whole-house dehumidifiers use a lot of electricity?

• <div><p>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. </p></div>

They showed up when they said they would, they worked in an efficient and professional way, and their price was reasonable. There was a misunderstanding at first about the finish, but they made the correction at their expense.
