Air ConditioningTips and AdviceShould you turn off your A/C while you are away?

June 1, 2023by Dev

Many homeowners wonder whether to turn off their air conditioning unit when they leave home for work, vacation, or overnight. There’s no clear-cut answer, as it depends on several factors. There are some pros and cons of turning off your air conditioning unit and provide some tips on saving energy while keeping your home comfortable.

Benefits of Turning Off Your A/C

  1. Energy Savings: Turning off your air conditioning unit when you’re not at home can save energy and reduce your electricity bills. According to the US Department of Energy, you can save up to 10% on your annual cooling costs by raising your thermostat by 7-10 degrees Fahrenheit for 8 hours a day.
  2. Longer Lifespan: Giving your air conditioning unit a break by turning it off can help extend its lifespan. The less it runs, the less wear and tear it experiences, which can reduce the need for repairs and replacement.
  3. Environmental Impact: Saving energy by turning off your air conditioning unit reduces your carbon footprint and contributes to a healthier environment.

Cons of Turning Off Your A/C

  1. Comfort: Turning off your air conditioning unit can make your home uncomfortably warm and humid, especially during the summer months. If pets or plants require a consistent temperature, turning off your A/C may not be the best option.
  2. Moisture and Mold: When the air conditioning unit is turned off, the humidity in your home can increase, leading to the growth of mold and mildew. This can cause health problems and damage to your home.
  3. Increased Energy Use: Turning off your air conditioning unit for extended periods can cause your home’s temperature to rise significantly, requiring more energy to cool it down when you return. This can negate any potential energy savings and increase your electricity bill.

Tips to Save Energy and Keep Your Home Comfortable

If you’re unsure whether to turn off your air conditioning unit, here are some tips to save energy while keeping your home comfortable:

  1. Use a Programmable Thermostat: A programmable thermostat allows you to set different temperatures for different times of the day. You can program your thermostat to raise the temperature when you’re not home and lower it before you return, ensuring your home is comfortable when you arrive.
  2. Use Ceiling Fans: Ceiling fans circulate air throughout your home, making it feel cooler without relying solely on your air conditioning unit. You can also use portable fans to direct cool air to specific areas of your home.
  3. Seal Air Leaks: Air leaks in your home can cause your air conditioning unit to work harder to maintain a comfortable temperature. Seal any air leaks around doors, windows, and ductwork to improve your home’s energy efficiency.
  4. Keep Your A/C Unit Maintained: Regular air conditioning unit maintenance can help improve its efficiency and reduce the need for repairs. Schedule annual tune-ups with a professional HVAC technician to ensure your unit functions optimally.

Whether to turn off your air conditioning unit when you leave your home is a personal decision that depends on several factors. If you want to save energy and reduce your electricity bills, consider using a programmable thermostat, sealing air leaks, and maintaining your air conditioning unit. However, if you have pets or plants that require a consistent temperature, or if turning off your unit causes moisture and mold problems, it may be best to leave it running at a higher temperature.
