ac works harder

Q: My electric bill is often higher in the summer than in the spring but I don’t think I’m using much more electricity. Does Wake Electric charge higher kWh rates if the weather gets really hot or really cold?

A: No. Wake Electric does not increase your kWh charge in extreme weather.

As the humidity and temperature increases in the summer, your cooling system has to work much harder to keep your home cool. Also, every degree you lower your thermostat means your unit is working longer to achieve lower temperatures. Typically, monthly home electricity consumption peaks in July and August when temperatures and cooling demand are the highest. Eighteen percent of annual household electricity use is for air conditioning.

Individual air-conditioning units are more common in mobile homes and apartments than in single-family homes, and they are also common in older homes where it may be more difficult or expensive to add a central system and the ductwork most central systems require. These units also work harder and longer to maintain cooler temperatures in the hottest days of summer.
