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 expenses. To keep your air conditioning costs controlled you may be wondering, is it cheaper to leave your AC on all day in the summer in Houston?

It’s a popular belief that turning your air conditioner on and off throughout the day is inefficient. This is actually a myth.

Keeping your air conditioner running all the time means you’re not using it very efficiently. We recommend moving your thermostat to a higher setting when you’re away, and lowering it when you return. You can achieve this with a programmable thermostat. Or, a smart thermostat is able to do the job for you.

It’s far more work for your system to achieve the same temperature for many hours. 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 utility bills, it could also lead to a shortened life expectancy for your AC unit.

No matter what, the greater the difference between your house’s temperature and the outside temperature, the more 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 suggestions based on recommendations from the U.S Department of Energy (DOE) and ENERGY STAR®.

6 Approaches to Enhance Your Air Conditioner’s Energy Efficiency

  1. Modify Your Temperature. The DOE says that you can conserve up to 10% yearly on heating and cooling by raising your thermostat 7-10 degrees while you’re out. In the hotter months, it’s suggested to keep your thermostat at 78 degrees at the time you’re home and 88 degrees when you’re away. It’s also important to avoid setting your thermostat to a colder setting than usual when you turn on your air conditioner. This doesn’t actually cool down your residence any sooner, it just causes bigger electric costs. While these temperatures might feel toasty, there are additional 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 a mere 2 degrees and using your ceiling fan can decrease air conditioning costs by up to 14% throughout the summer. It’s important to keep in mind that fans cool people, not areas. So, when you leave the room, turn the fan off to be energy efficient. Also, keeping blinds low and curtains drawn throughout the day helps keep cooler air inside. There are also some window coverings meant to deliver additional insulation and improve energy efficiency.
  3. Adequately Seal All Doors, Windows and Openings. Leaky gaps all around a home permit conditioned air to quickly slip out and the heat to get inside. This could cause your air conditioner needing to work harder to keep your home comfortable and your energy expenses to increase. Make certain that any cracks, doors and windows are adequately sealed. Caulking or weather-stripping are simple fixes for leaks or drafts near windows and doors.
  4. Schedule Routine Tune-Ups. Scheduling air conditioner maintenance ensures your AC is always running at its most efficient. This permits our experts to spot simple issues before they turn into significant troubles. A clean AC is usually more efficient and can even live longer.
  5. Invest in a Smart Thermostat. One of the best methods to assure comfort and energy savings is with a smart thermostat. This thermostat intuitively adjusts the temperature based on your day-to-day schedule. It works together with your smartphone to sense when you’re home or gone to enhance your energy efficiency. In fact, ENERGY STAR says that a smart thermostat could possibly save you about $180 every year on energy bills.
  6. Consider Replacing Your Air Conditioning Unit. You can expect a properly maintained air conditioner to live for 15-20 years. But if you’re regularly contacting us for air conditioning repair or your utility bills are rising with no altering in thermostat settings, it might be time for a replacement. We offer a number of energy-efficient air conditioners, including ENERGY STAR models that can help you save more on cooling without trading comfort.
