June 19, 2020

As the temperature rises, so does your air conditioning expenses. To keep your air conditioning expenses controlled you may be asking yourself, is it cheaper to leave your AC on all day in the summer in Rapid City?

It’s a common belief that turning your AC on and off [[throughout the day is inefficient. This is actually false.

It’s a lot more taxing for your system to achieve a consistent temperature for many hours. It can also cause a lot of strain on your equipment, since it’s frequently turning on and off.

So, on top of it increasing your utility bills, it can also result in a shorter life span for your AC.

Regardless, the bigger the difference between your home’s 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 summer season? Here are our tips based on recommendations from the U.S Department of Energy (DOE) and ENERGY STAR®.

6 Methods to Enhance Your Air Conditioner’s Energy Efficiency

  1. Modify Your Temperature. The DOE states that you can spend up to 10% less yearly on heating and cooling by turning up your thermostat 7-10 degrees when you’re out of the house. During the summer, it’s advised to position your thermostat at 78 degrees at the time you’re home and 88 degrees when you’re out. It’s also important to forgo setting your thermostat to a colder setting than usual when you turn on your air conditioner. This doesn’t actually cool down your house any sooner, it just leads to higher utility expenses. While these temperatures may feel warm, there are many approaches to keep cooler without having to consistently run the AC unit.
  2. Use Fans, Curtains and Blinds. ENERGY STAR says raising the thermostat by only 2 degrees and utilizing your ceiling fan can decrease energy by up to 14% over the course of the cooling season. It’s important to be mindful that that fans cool people, not spaces. So, when you head out of the room, turn the fan off to conserve energy. Also, keeping blinds down and curtains drawn for the duration of the day helps keep chilled air indoors. There are also some window solutions made to deliver added insulation and improve energy efficiency.
  3. Properly Seal All Doors, Windows and Openings. Leaky cracks all around a home let cool air to easily slip out and warmer air to get within. This could result in your AC unit having to work harder to keep your house cooler and your energy expenses to skyrocket. Make sure that any cracks, doors and windows are suitably sealed. Caulking or weather-stripping are quick mends for leaks or drafts near windows and doors.
  4. Arrange Annual Maintenance. Scheduling air conditioner maintenance makes sure your air conditioner is always functioning at its most efficient. This allows our experts to locate little issues before they turn into major dilemmas. A well-kept air conditioner is generally more efficient and can even run for a greater period of time.
  5. Invest in a Smart Thermostat. One of the easiest methods to guarantee comfort and energy savings is with a smart thermostat. This thermostat automatically adjusts the temperature based on your day-to-day schedule. It works with your smartphone to know when you’re at your house or away to maximize your energy savings. In fact, ENERGY STAR mentions that a smart thermostat could potentially save you about $180 per year on HVAC bills.
  6. Consider Replacing Your Air Conditioner. You can foresee an adequately cared for AC unit to run for 15-20 years. But if you’re frequently calling us for air conditioning repair or your utility bills are rising with no fluctuations in thermostat settings, it might be time for a replacement. We carry a number of energy-efficient air conditioners, including ENERGY STAR models that can help you save more on cooling without compromising comfort.
