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

June 19, 2020

As the heat rises, so does your AC costs. To keep your cooling expenses controlled you might be asking yourself, is it cheaper to leave your AC on all day in the summer in St. Louis?

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 AC going constantly means you’re not using it very efficiently. We advise setting your thermostat higher when you’re elsewhere, and lowering it when you come home. You can do this with a programmable thermostat. Or, a smart thermostat can do everything for you.

It’s considerably more work for your system to achieve the same setting all day long. It can also cause a lot of wear and tear to your air conditioner, since it’s frequently turning on and off.

So, on top of it increasing your energy bills, it might also lead to a shorter life expectancy for your HVAC system.

In any case, the larger the difference between your indoor temperature and the outside temperature, the greater your air conditioning bills will be. So, what can you do to remain cool and keep your utility bills lower in the hot weather? Here are our tips based off of recommendations from the U.S Department of Energy (DOE) and ENERGY STAR®.

6 Ways to Enhance Your Air Conditioner’s Energy Efficiency

  1. Modify Your Thermostat. The DOE affirms that you can conserve up to 10% annually on heating and cooling by turning up your thermostat 7-10 degrees while you’re out. In the warmer months, it’s recommended to set your thermostat at 78 degrees when you’re home and 88 degrees when you’re away. It’s also important to abstain from setting your thermostat to a lower setting than normal when you turn on your AC. This doesn’t actually cool down your house any faster, it just leads to higher energy expenses. While these temperatures may seem high, there are additional approaches to keep cool without having to always run the air conditioning.
  2. Take Advantage of Fans, Curtains and Blinds. ENERGY STAR says increasing the thermostat by only 2 degrees and utilizing your ceiling fan can lower air conditioning costs by up to 14% during the course of the warm months. It’s important to remember that fans cool people, not spaces. So, when you exit the room, turn the fan off to be energy efficient. Furthermore, keeping blinds lowered and curtains closed throughout the day helps keep cooler air indoors. There are also some window solutions intended to deliver additional insulation and boost energy efficiency.
  3. Effectively Seal All Doors, Windows and Openings. Leaky cracks all across a house enable cool air to rapidly slip out and the heat to get in. This may lead to your AC having to work harder to keep your house comfortable and your energy expenses to rise. Make certain that any cracks, doors and windows are suitably sealed. Caulking or weather-stripping are easy fixes for leaks or drafts around windows and doors.
  4. Plan for Regular Tune-Ups. Scheduling air conditioner maintenance ensures your equipment is always performing at its most energy efficient. This lets our pro to detect little issues before they turn into substantial problems. A maintained air conditioner is usually more efficient and can even last longer.
  5. Invest in a Smart Thermostat. One of the greatest ways to ensure comfort and energy savings is with a smart thermostat. This thermostat instinctively adapts the temperature based on your day-to-day schedule. It works along with your smartphone to sense when you’re home or away to enhance your efficiency. In fact, ENERGY STAR says that a smart thermostat could potentially save you about $180 every year on heating and cooling bills.
  6. Consider Replacing Your AC Unit. You can expect an adequately maintained AC unit to last for 15-20 years. But if you’re regularly calling us for air conditioning repair or your AC expenses are climbing with no shifts in thermostat settings, it may be time for an upgrade. We supply a number of energy-efficient air conditioners, such as ENERGY STAR models that can help you save more on cooling without compromising comfort.
