Can I Leave My Windows Open This Fall?

As we transition from air conditioning to heating, homeowners often wonder the appropriate time to officially make the switch. Turning on your heating system depends on personal preferences, because some enjoy the outdoor temperatures providing home comfort. Many wonder if having their windows open during the nice weather is beneficial or harmful to them, their HVAC system, and their home. In this blog, we will answer the common window questions that come with the fall season.

Air Conditioning vs. Windows

Fall temperatures in Foley usually mean warm days and cool nights, which makes it confusing whether to continue to utilize air conditioning or not. In our opinion, you should either leave your AC on or open your windows. Doing both at the same time could be problematic for you, your home, and HVAC system.

Pros Of Air Conditioning

  • Your air conditioner can ensure your comfort remains, while relying on windows can bring unpredictable temperatures.
  • Keeping your windows closed and air conditioner on can help regulate air quality and humidity.

Pros Of Windows

  • Open windows allow you to air out your home from dust and debris trapped inside.
  • Using windows rather than AC can help save money on utility costs.
  • Windows can provide a comfortable temperature and fresh air.

Why You Shouldn’t Have Your Windows Open With The AC On

While opening your windows in comfortable weather seems fine, it can actually cause more harm than good. Below are reasons why you should not open your windows while the air conditioner is running.

  • Overworked Unit
  • Higher Utility Bills
  • Decreased Air Quality
  • Reduced Efficiency

Overworked Unit

Your air conditioner works hard to meet the thermostat setting, and opening windows allows cool air to escape. Even though outdoor air can make your home comfortable, if the temperature is above your thermostat setting it can cause an overworked unit. The thermostat will sense indoor air is not at the setting, and work until the temperature is met. With open windows, your air conditioner will never meet the thermostat setting. An overworked AC system can result in costly breakdowns and repairs.

Higher Utility Bills

If your air conditioner is working overtime, it is using more energy to function. The more energy your unit is using, the higher your utility costs will be. To save money each month, we recommend choosing to use your air conditioner or windows for comfort – not both.

Decreased Air Quality

Open windows let outdoor humidity, pollutants, and allergens in your home, which harms your air quality. You may experience heightened allergies in your home and have to change your air filter more often. Increased humidity can cause your air conditioner to work harder in hopes to remove the extra moisture. High humidity levels can cause damage to your home, furniture, and electronics. Additionally, open windows can let in pests and bugs.

Reduced Efficiency

When you open windows while your AC is on, you increase the workload for your system. A more efficient air conditioner is better for everyone due to the benefits it provides. Keeping windows closed will increase air conditioner efficiency and maintain a reliable cooling system.

Open Your Windows!

We encourage homeowners to open their windows this fall at their own risk. Fresh air can make all the difference in your home and remove built-up toxins in the air. However, open windows can have negative effects. If you are considering turning off your AC and opening windows at night, the same pros and cons can apply.
