How to EFFECTIVELY Cool Your Home in Extreme Temps

At GGHRA, we want residents to stay safe, comfortable, and informed during periods of extreme heat.

Understanding the 20-Degree Rule
One of the most common misconceptions about air conditioning is that setting the thermostat extremely low will cool a home faster. Unfortunately, that's not how air conditioning systems work.

Most residential air conditioning systems are designed to cool a home approximately 20 degrees below the outdoor temperature. When temperatures outside reach 95°F or higher, setting your thermostat to 65°F will not make your home cool down more quickly.

Instead, it can cause your system to run continuously, increase energy consumption, and in some cases lead to the unit freezing up or requiring repairs and high utility costs.
For example:

• Outside Temperature: 95°F
• Recommended Thermostat Setting: 75°F

The most efficient and comfortable thermostat setting during extreme heat is generally between 75°F and 80°F.
Additional Ways to Keep Your Home CoolYour air conditioner does not have to do all the work. Small changes can help reduce heat inside your home and improve comfort.

Close, Blinds, and Curtains
Sunlight streaming through windows can significantly increase indoor temperatures. Keep blinds and curtains closed during the hottest part of the day.

Keep Doors Closed
Every time an exterior door is opened, cool air escapes and hot air enters. Limit the amount of time doors remain open.

Use Ceiling Fans
Fans help circulate air and can make rooms feel cooler, allowing your air conditioner to operate more efficiently.

Reduce Indoor Heat Sources
Ovens, dryers, and other heat-producing appliances can increase indoor temperatures. When possible, limit their use during the hottest hours of the day.

Heat Safety Tips
Extreme heat can be dangerous, especially for children, older adults, and individuals with certain medical conditions.

During this heat advisory:

• Drink plenty of water throughout the day.
• Limit outdoor activities during peak afternoon hours.
• Check on elderly neighbors, friends, and family members.
• Ensure pets have access to shade and fresh water.
• Never leave children or pets in a parked vehicle, even for a short time.

Helping Your AC Work Smarter
When temperatures soar, your air conditioner may run longer than usual. That's normal. The best thing you can do is set a reasonable temperature and allow the system to operate as designed.
Remember: Lowering the thermostat far below the recommended range will not cool your home faster. It will only make your system work harder.

By following these simple tips, you can stay comfortable, reduce energy costs, and help prevent unnecessary maintenance issues during the hottest days of the year.

Stay safe, stay cool, and watch for additional Resident Resources from GGHRA throughout the summer.
