Should I Keep My AC on ‘Auto’ or ‘On’?

Most people don’t know the difference between the “auto” and “on” settings on their air conditioner. Here’s a quick rundown of the difference and which setting will work best for your preferences.

The ‘Auto’ Setting

The “auto” setting will turn your air conditioner off when your home reaches the temperature you’ve set on the thermostat. The unit will then turn back on when the temperature in your home starts rising again.

The ‘On’ Setting

The “on” setting keeps your air conditioning system running constantly, no matter what the temperature in your home is.

How To Choose

So, which setting should you use? It depends on your preference and needs. If you want to make sure your home is always cool and comfortable, then the “on” setting is probably best for you. However, if you’re trying to save energy and money, then the “auto” setting is a better option.

Here’s a closer look at some of the things you should consider when making this decision:

  • The temperature outside: If it’s very hot outside, your AC will have to work harder to keep your home cool. As a result, it may be more efficient to keep it on “auto,” so it doesn’t have to run constantly.
  • The temperature in your home: If you have a lot of windows or if your home tends to get warm quickly, you may want to keep your AC on “on” so it doesn’t have to cycle on and off as often.
  • The type of air conditioner you have: Some air conditioners are more efficient than others, so it’s worth checking with the manufacturer or your local HVAC contractor to see what they recommend.
  • Your personal preferences: Ultimately, the best setting for your AC is the one that keeps you comfortable while saving energy. So, if you’re not sure what to choose, experiment a bit and see what works best for you.

Tips To Save Money on Your AC This Summer

When it starts to warm up outside, the last thing you want is a high electric bill from your AC. Here are some tips to help you save money on your AC this summer:

  1. Keep your thermostat at 78 degrees or higher. For every degree you lower the temperature, you’ll see about a 7% increase in your energy usage.
  2. Use ceiling fans to circulate air and make the room feel cooler.
  3. Close off any unused rooms, so you’re not cooling them unnecessarily.
  4. Make sure your air conditioner is properly maintained and serviced before the start of the season. A well-maintained AC unit will run more efficiently.
  5. Invest in energy-efficient window treatments to help keep the heat out.

By following these tips, you can save money on your air conditioning this summer and keep your home cool and comfortable.
