Is it Cheaper to Leave Your AC on All Day in the Summer?

June 19, 2020

As the heat increases, so does your air conditioning bills. To keep your AC costs under control you could be thinking, is it cheaper to leave your AC on all day in the summer in Tuscaloosa?

It’s a common belief that turning your air conditioner on and off throughout the day is wasteful. This is actually a misconception.

Keeping your AC going all day means you’re not using it very efficiently. We recommend setting your thermostat higher when you’re elsewhere, and turning it back down when you come back. You can accomplish this with a programmable thermostat. Or, a smart thermostat is able to do the job for you.

It’s much more taxing for your system to keep the same setting all day long. It can also cause a lot of stress on your equipment, since it’s frequently turning on and off.

So, on top of it increasing your utility bills, it can also lead to a shortened life cycle for your AC.

Regardless, the greater the difference between your indoor temperature and the outside temperature, the higher your air conditioning bills will be. So, what can you do to keep cool and keep your utility bills lower in the summer season? Here are our tips based on recommendations from the U.S Department of Energy (DOE) and ENERGY STAR®.

6 Approaches to Increase Your Air Conditioner’s Energy Efficiency

  1. Change Your Temperature. The DOE says that you can spend up to 10% less annually on heating and cooling by increasing your thermostat 7-10 degrees during the time you’re out of the house. Through the summer, it’s recommended to set your thermostat at 78 degrees when you’re home and 88 degrees when you’re elsewhere. It’s equally as important to avoid setting your thermostat to a cooler setting than normal when you turn on your air conditioner. This doesn’t actually cool your house any quicker, it just causes more expensive electric costs. While these temperatures could feel toasty, there are a number of methods to keep cooler without having to always run the air conditioning.
  2. Use Fans, Curtains and Blinds. ENERGY STAR says turning up the thermostat by just 2 degrees and turning on your ceiling fan can lower air conditioning costs by up to 14% over the course of the summer season. It’s important to remember that fans cool people, not rooms. So, when you leave the room, turn the fan off to save energy. Also, keeping blinds down and curtains shut throughout the day helps keep conditioned air indoors. There are also some window coverings designed to deliver added insulation and increase energy efficiency.
  3. Properly Seal All Doors, Windows and Openings. Leaky openings around a home allow for cooler air to rapidly get out and warmer air to get in. This can cause your AC equipment being required to work harder to keep your home cool and your energy bills to climb. Make sure that any openings, doors and windows are properly sealed. Caulking or weather-stripping are quick mends for leaks or drafts close to windows and doors.
  4. Arrange Regular Maintenance. Scheduling air conditioner maintenance ensures your AC is always running at its most efficient. This lets our pro to spot little issues before they result in substantial problems. A clean air conditioner is typically more efficient and may even run for a longer period of time.
  5. Invest in a Smart Thermostat. One of the easiest methods to ensure comfort and cost-effectiveness is with a smart thermostat. This thermostat intuitively changes the temperature based on your day-to-day schedule. It works with your smartphone to sense when you’re at your house or away to optimize your energy savings. In fact, ENERGY STAR says that a smart thermostat could actually save you about $180 per year on HVAC expenses.
  6. Consider Replacing Your AC. You can expect a properly taken care of AC unit to run for 15-20 years. But if you’re regularly contacting us for air conditioning repair or your utility expenses are increasing with no shifts in thermostat settings, it may be time for an upgrade. We offer many energy-efficient air conditioners, such as ENERGY STAR models that can help you save more on cooling without compromising comfort.
