When the Florida sun blazes relentlessly over Ft. Myers, cranking up the air conditioner is practically second nature. There’s nothing quite like stepping into a refreshingly cool home after enduring the sweltering heat outside. But is there such a thing as too cool? Surprisingly, yes. Keeping your thermostat set too low all summer long might seem like the perfect way to escape the heat, but it can actually cause problems for both your health and your home.
In this blog post, we’ll explore why excessively low temperatures might be harmful and how you can strike the perfect balance for comfort and safety.
The Ideal Indoor Temperature: What Experts Recommend
The U.S. Department of Energy recommends setting your thermostat to 78°F during the summer months when you’re home and awake. While this might seem a bit warm to some, it’s considered the optimal temperature for energy efficiency and comfort. For those who prefer a cooler setting, it’s advised not to drop the thermostat below 72°F for extended periods.
Yet, many Floridians push the limit, setting their thermostats to 68°F or even lower, aiming for that crisp, chilly indoor feel. While it might be refreshing, keeping your home this cold continuously can lead to some unexpected consequences.
Health Risks of Overcooling Your Home
1. Respiratory Issues and Allergies
Constantly running your AC at very low temperatures can dry out the air inside your home. This lack of humidity can irritate the respiratory tract, causing dry throats, sinus problems, and increased susceptibility to colds. Furthermore, air conditioners tend to recycle indoor air, which can lead to the buildup of dust, mold, and allergens if not properly maintained.
2. Increased Risk of Illness
Sudden temperature changes—like moving from 95°F outside to 65°F inside—force your body to work harder to regulate its temperature. This added strain can weaken your immune system, making you more vulnerable to illnesses. Studies have shown that rapid shifts in temperature can trigger stress responses in the body, leading to a higher likelihood of catching colds and respiratory infections.
3. Joint and Muscle Discomfort
If you’ve ever noticed your joints feeling stiff or sore in a chilly room, you’re not alone. Cold temperatures can cause muscles to contract, increasing tension and sometimes discomfort, particularly for those with arthritis. Keeping your home too cold for too long can exacerbate these symptoms.
How Low Temperatures Affect Your Home
1. Higher Energy Bills
It might seem obvious, but the lower you set your thermostat, the harder your AC has to work. Maintaining a 65°F indoor temperature when it’s 95°F outside forces your system to run almost continuously, which significantly drives up your energy bills. According to the U.S. Energy Information Administration, every degree below 78°F increases your cooling costs by about 3–5%.
2. Excessive Wear and Tear on Your HVAC System
Running your air conditioner non-stop throughout the summer at extremely low temperatures places a tremendous amount of strain on the system. Over time, this can lead to:
-
Compressor failure
-
Refrigerant leaks
-
Frozen evaporator coils
These issues not only reduce efficiency but also shorten the lifespan of your unit, potentially costing thousands in repairs or premature replacement.
3. Moisture and Condensation Problems
When indoor temperatures are significantly lower than outdoor temperatures, condensation can form on windows and walls. In humid climates like Ft. Myers, this can quickly lead to mold growth. Mold thrives in damp, cool environments, and once it takes hold, it’s not only difficult to remove but also a serious health hazard.
Striking the Right Balance: Recommended Settings
To keep your home comfortable and your AC running efficiently, follow these guidelines:
-
78°F when you’re home and active
-
85°F when you’re away for extended periods
-
82°F while you’re sleeping
If you prefer cooler temperatures, consider adjusting gradually rather than a drastic drop. Using fans to circulate air can also make the room feel cooler without needing to lower the thermostat excessively.

Tips for Keeping Cool Without Overcooling Your Home
1. Use Ceiling Fans Efficiently
Ceiling fans create a wind-chill effect, making the room feel cooler than it actually is. You can comfortably set your thermostat 4°F higher when using fans.
2. Close Blinds and Curtains
Solar heat gain through windows can significantly increase the temperature indoors. By keeping blinds and curtains closed during the hottest parts of the day, you can reduce indoor heat by up to 33%.
3. Seal Air Leaks
Drafty windows and poorly sealed doors can let cool air escape. Proper sealing helps maintain consistent indoor temperatures, reducing the temptation to lower the thermostat.
4. Cook and Use Appliances Wisely
Stoves, ovens, and even clothes dryers can generate a lot of heat. Opt for grilling outdoors or using the microwave during peak heat hours to minimize indoor heat buildup.
