Florida Winters Aren’t Like Anywhere Else
If you live in Brevard County, you already know our version of “winter” doesn’t look like much of the rest of the country. While friends up north are shoveling snow, we’re still seeing daytime highs in the 60s and 70s — sometimes warmer. But that doesn’t mean the air conditioning question disappears. Homeowners often ask: should you still run your AC in the winter in Florida? The short answer is yes — but not in the same way you rely on it in the summer. In our mild climate, the focus shifts from cooling your home to controlling humidity, circulating air, and protecting your equipment from unnecessary wear and tear.
Why You Might Run Your AC in Winter
Even during cooler months, Florida’s humidity never really goes away. That lingering moisture can make your home feel damp, musty, or just plain uncomfortable. Running your air conditioner occasionally helps dehumidify the air and keep things fresh indoors. Your AC system also helps circulate air, which prevents rooms from feeling stagnant or stuffy. And on those random warm days — because yes, they always sneak into a Florida winter — your AC can take the edge off and bring comfort back quickly.
Risks of Running Your AC When It’s Too Cold
While humidity control is important, running your air conditioner when outdoor temps dip too low comes with real risks:
-
Frozen coils: When it’s under 60°F outside, condensation on your cooling coils can freeze, leading to major equipment damage.
-
Compressor failure: Cold weather thickens the lubricant in your compressor, which can cause it to overheat and break down. That’s a costly repair you don’t want to face.
-
Inefficient operation: Standard AC units simply aren’t designed to run in cold weather. Forcing your system to cool when it’s chilly outside wastes energy, stresses the equipment, and drives up utility bills.
The takeaway? Don’t set your AC to cool once the outdoor temperature drops below 60°F.
Smart Alternatives for Staying Comfortable in a Florida Winter
So if blasting the AC isn’t the right move when it’s cooler outside, what are your options? Luckily, Florida homeowners have plenty of alternatives:
-
Switch to heat mode: Most systems here are heat pumps or have electric heating elements (heat strips). Heat pumps are efficient and perfect for Florida’s mild winters. Heat strips are less efficient but work well for short bursts of heating.
-
Fan-only setting: This circulates the air without engaging the cooling cycle, managing humidity without straining your compressor.
-
Open windows: On crisp, dry days, fresh air is free and effective.
-
Use ceiling fans wisely: Flip the switch to reverse the blade rotation in winter. A clockwise spin at low speed pushes warm air down where you can feel it.
-
Control humidity: If your system has a dehumidification mode, use it. Standalone dehumidifiers also work well for problem areas.
-
Adjust your thermostat: When heating, set it around 68°F. Lower it a bit when you’re sleeping or away to save energy.
-
Improve insulation: Seal drafts, use thermal curtains, and keep conditioned air where it belongs — inside.
So, Should You Run Your AC in Winter in Florida?
Yes, but carefully. Use your AC for air circulation and dehumidification, not cooling, when temps drop. Never run it below 60°F outdoors to avoid damaging your system. Instead, rely on heat pumps, heat strips, fans, and simple ventilation tricks to keep your home comfortable and safe. In Florida, it’s not about surviving the cold — it’s about managing humidity and keeping your system running efficiently all year long.
