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

June 19, 2020

As the temperature rises, so does your air conditioning bills. To keep your air conditioning costs controlled you might be asking yourself, is it cheaper to leave your AC on all day in the summer in Elk River?

It’s a popular belief that turning your AC unit on and off throughout the day is a waste of energy. This is actually not true.

Keeping your air conditioner on all the time means you’re not using it very efficiently. We recommend setting your thermostat higher when you’re out, and lowering it when you come home. You can do this with a programmable thermostat. Or, a smart thermostat is able to do the work for you.

It’s considerably more work for your system to achieve a constant temp for many hours. It can also lead to a lot of stress on your air conditioner, since it’s constantly turning on and off.

So, on top of it increasing your energy bills, it might also lead to a reduced life cycle for your AC unit.

Regardless, the bigger the difference between your indoor temperature and the outside temperature, the more your energy expenses will be. So, what can you do to keep cool and keep your electric bills low in the hot weather? Here are our suggestions based off of recommendations from the U.S Department of Energy (DOE) and ENERGY STAR®.

6 Approaches to Increase Your Air Conditioner’s Energy Efficiency

  1. Modify Your Temperature. The DOE affirms that you can spend up to 10% less per year on heating and cooling by raising your thermostat 7-10 degrees when you’re away. During the warmer months, it’s recommended to set your thermostat at 78 degrees while you’re home and 88 degrees when you’re elsewhere. It’s equally as important to avoid setting your thermostat to a colder setting than normal when you turn on your AC. This doesn’t actually cool down your residence any sooner, it just causes more expensive energy expenses. While these temperatures could seem warm, there are additional ways to keep comfortable without having to always run the air conditioning.
  2. Take Advantage of Fans, Curtains and Blinds. ENERGY STAR says turning up the thermostat by a mere 2 degrees and using your ceiling fan can decrease energy by up to 14% throughout the summer. It’s important to be mindful that that fans cool people, not spaces. So, when you exit the room, turn the fan off to save energy. Additionally, keeping blinds lowered and curtains closed during the day helps keep cooler air inside. There are also some window coverings made to deliver added insulation and improve energy efficiency.
  3. Adequately Seal All Doors, Windows and Openings. Leaky openings all across a house permit conditioned air to rapidly get out and warm air to get in. This may lead to your air conditioner having to work harder to keep your home cooler and your energy expenses to rise. Make certain that any gaps, doors and windows are suitably sealed. Caulking or weather-stripping are quick fixes for leaks or drafts near windows and doors.
  4. Plan for Annual Tune-Ups. Scheduling air conditioner maintenance makes sure your air conditioner is always performing at its most efficient. This lets our professionals to identify little issues before they turn into serious problems. A well-kept AC unit is usually more efficient and might even run for a greater period of time.
  5. Invest in a Smart Thermostat. One of the greatest approaches to guarantee comfort and energy savings is with a smart thermostat. This thermostat automatically changes the temperature based on your daily schedule. It works with your smartphone to know when you’re home or elsewhere to maximize your efficiency. In fact, ENERGY STAR states that a smart thermostat could actually save you about $180 every year on energy expenses.
  6. Consider Replacing Your Air Conditioner. You can expect an adequately cared for AC unit to live for 15-20 years. But if you’re regularly contacting us for air conditioning repair or your energy expenses are rising with no change in thermostat settings, it may be time for a replacement. We supply a number of energy-efficient air conditioners, such as ENERGY STAR models that can help you save more on cooling without bargaining comfort.
