Why Your AC Still Matters in December: Winter Comfort Tips for Southwest Florida Hom

By

Even though December is considered “winter,” if you live in Naples, Florida, you already know—air conditioning season never really ends. While the rest of the country is scraping ice off windshields, Southwest Florida residents are still running their air conditioners to stay cool, control humidity, and breathe cleaner indoor air.

If you’re tempted to ignore your AC during the cooler months, here’s why it’s still one of your most important home systems this time of year—and what you can do to keep it running efficiently.

1. Humidity Control is Still Critical in Naples

Naples averages over 70% relative humidity in December. Even if the temperatures drop slightly, the air still holds a lot of moisture. High indoor humidity can lead to:

  • Mold and mildew growth

  • Musty odors

  • Allergy flare-ups

  • Warped wood or furniture damage

Your air conditioning system helps dehumidify your home—even when it’s not working full blast. Running your AC intermittently, or using the “Dry Mode” setting if available, can help maintain healthy humidity levels all winter.

2. Heat Pumps: AC and Heating in One

Many Naples homes use heat pumps instead of traditional furnaces. These systems are perfect for Florida’s mild winters because they can cool your home in summer and warm it slightly during winter.

In December, when temperatures occasionally dip into the 50s or low 60s, your heat pump becomes a key comfort feature. Keeping your system well-maintained ensures it can switch smoothly between heating and cooling when needed.

3. Air Quality Is a Year-Round Concern

When you close windows to keep out the (slightly) chilly air, your home becomes more sealed—and that means more potential for dust, pet dander, and allergens to circulate.

Your AC’s air filter and ventilation system are essential for maintaining healthy indoor air quality in winter. Make sure to:

  • Change your air filter at least every 30–60 days

  • Consider a whole-home air purifier or UV light system

  • Schedule a duct cleaning if it hasn’t been done in a while

4. December Is the Perfect Time for Maintenance

Because winter is the “off-season” for AC emergencies in Florida, December is a great time to schedule HVAC maintenance. Regular tune-ups help:

  • Improve energy efficiency

  • Prevent mid-season breakdowns

  • Extend the life of your unit

  • Catch small issues before they become expensive repairs

5. Energy Savings Start With Smart Thermostat Settings

Even if your AC isn’t running 24/7 in December, it’s still using energy. Here are a few thermostat tips to save on your utility bills:

  • Set your thermostat to 75–78°F when home

  • Increase the temperature a few degrees when you’re away

  • Use ceiling fans to circulate air and reduce the need for cooling

  • Consider installing a smart thermostat to optimize energy use
