Atlantic hurricane season runs from June 1 through November 30, which overlaps almost exactly with the months your AC works hardest in Broward County. When a storm threatens, your outdoor condenser is one of the most exposed and expensive pieces of equipment on your property. A little preparation keeps it from becoming a claim, a hazard, or a week without cooling in September heat. This guide walks through what to do before the storm, how to shut down safely, and what to check before you flip the system back on.
TL;DR
- Atlantic hurricane season is June 1 to November 30, per NOAA, so treat AC prep as a seasonal habit, not a last-minute scramble.
- Do NOT cover the outdoor condenser while it is running, and do not wrap it airtight. Secure or strap it, and use a breathable cover only after the system is off.
- Add a surge protector and clear the condensate drain before the season, then turn the whole system off at the thermostat and the breaker as the storm approaches.
- After the storm, check for flooding, debris, and electrical damage before you restart. If the unit sat in floodwater, keep it off and call a licensed pro.
- Photograph your equipment before and after for insurance, and return home only when officials say it is safe.
How Do You Protect The Outdoor Condenser Before A Storm?
Your condenser is built to sit outside in wind and rain, so the real threats are flying debris, flooding, and electrical surges, not the storm itself. The single most important rule: never cover a condenser that is running, and never seal it airtight. A tightly wrapped unit traps moisture and can be damaged if someone forgets it is covered and turns the system on.
Here is the safe order of operations.
- Clear the area around the unit. Move patio furniture, potted plants, grills, and loose yard items well away. In a hurricane, anything unsecured becomes a projectile, and Ready.gov urges securing outdoor objects before the wind arrives.
- Secure or strap the unit if flooding or extreme wind is forecast. Hurricane straps or a manufacturer-approved tie-down kit anchor the condenser to its pad. This is the right call for evacuation zones and low-lying coastal properties.
- Cover it only after shutdown, and only with a breathable cover. A proper AC cover or breathable tarp held with bungee cords sheds debris. Skip plastic that seals in humidity.
- Know your options. If you live in a storm-surge or flood zone, ask an HVAC pro whether raising the unit on a taller pad or platform makes sense before the next season.
Do not try to move or elevate the condenser yourself. It is connected by refrigerant lines that a homeowner should never disturb.
Why Does Surge Protection Matter During Hurricane Season?
Lightning and grid instability during a storm can send a power surge through your home’s wiring, and the compressor in your AC is one of the costliest components a surge can destroy. Protecting against that surge is far cheaper than replacing the equipment it guards.
There are two layers worth understanding. A whole-house surge protector installed at your electrical panel is the strongest defense, and it protects every appliance in the home, not just the AC. Installing one is licensed electrical work, so book it with a qualified contractor well before the season, not the day a warning posts. At the equipment level, a hard-start kit or a dedicated surge device at the condenser adds a second line of defense that a pro can add during a routine tune-up.
The reason this matters most in a storm: the biggest surge risk is not while the AC is running, but when power flickers off and then snaps back on. That is exactly why shutting the system down before the storm, covered below, is so effective.
Should You Clear The Condensate Drain Before A Storm?
Yes. Heavy rain and high humidity during a hurricane push your drainage system to its limit, and a clogged condensate line can back up, trip the system’s float switch, and leave you with water damage right when you least want it. Clearing the drain is a safe homeowner task and takes only a few minutes.
The line carries the moisture your AC pulls from the air out of the house. In our climate it clogs with algae and slime faster than in drier regions. To keep it flowing, locate the drain line near the indoor air handler and at its outdoor exit point, then use a wet/dry vacuum on the outdoor outlet to pull any clog free. Flushing the line with a cup of distilled vinegar every month or two through the season keeps buildup from forming in the first place. If water still pools around the indoor unit after you clear the line, that points to a deeper blockage and a service call. Our related AC maintenance schedule for South Florida covers this on a year-round cadence.
How Do You Turn The AC Off Safely As A Storm Approaches?
When a hurricane or tropical storm warning is issued for Broward, shut the entire system down before the weather arrives. Running the AC during a storm invites surge damage, and a system that is already off cannot be harmed by the power flickering off and back on. This is the most important single action you can take for the equipment.
Follow this sequence in order.
- Turn the AC OFF at the thermostat. Set the mode to OFF so the system stops calling for cooling.
- Switch off the breakers. Trip both the indoor air handler and the outdoor condenser breakers at your electrical panel. Ready.gov recommends unplugging small appliances and turning off electrical equipment before a storm to guard against surges.
- Cover the outdoor unit if you choose to, using the breathable-cover method above, only now that it is fully powered down.
- Pre-cool the house first. Run the AC a few degrees cooler than usual in the hours before you shut it down, so the home stays comfortable longer once the power and system are off.
Leave the system off until the storm has fully passed and you have completed the after-storm checks below.
What Should You Check After The Storm Before Restarting?
Do not rush to turn the AC back on the moment the wind dies down. Restarting a unit that took on water or electrical damage can destroy the compressor and create a shock hazard. Inspect first, restart second. Nearly half of hurricane-related deaths happen after the storm, so caution here is not optional.
Walk the property carefully and check for three things before you touch the breaker.
- Flooding. If floodwater reached the condenser or the indoor air handler, keep the system OFF. The CDC advises turning off power at the main breaker and having any water-exposed equipment inspected by a professional before use. Motors, wiring, and controls that sat in water are not safe to run.
- Debris. Clear branches, leaves, and blown-in trash away from the condenser coil and fan. Remove any cover before restarting.
- Electrical damage. Look for scorch marks, loose or downed power lines near the unit, and damaged wiring. The National Weather Service warns to stay far away from downed power lines, which may be hidden in standing water. If you see any electrical damage, leave everything off and call a licensed technician.
If the unit is dry, clear, and undamaged, restore power at the breaker, wait a few minutes for any built-in delay, then set the thermostat to COOL. If it does not start cleanly, or blows warm air, stop and get a pro. For a full storm-season restart, our AC repair companies in Broward County directory helps you find a licensed one near you.
How Do You Document AC Damage For Insurance?
Good documentation is what turns a storm loss into a paid claim, and the best time to start is before the storm, not after. A clear before-and-after record shows an adjuster exactly what changed.
Before the season or before an approaching storm, photograph the condenser, the air handler, the model and serial number plate, and the surrounding area from several angles. Keep a copy of your equipment’s age, any recent maintenance receipts, and your homeowner’s policy details somewhere you can reach them even if the power is out. After the storm, before you move or clean anything, photograph any visible damage and standing water in the same detail. Then contact your insurer promptly and ask whether they require a licensed HVAC assessment. A written diagnosis from a pro strengthens the claim and separates true storm damage from ordinary wear.
When Should You Call A Licensed Pro?
Some storm tasks are safe for a homeowner, and some are strictly for a licensed professional. You can safely clear the condensate drain, secure loose items, cover a powered-down unit, and shut the system off at the breaker. Everything involving refrigerant, wiring, a whole-house surge protector, elevating the condenser, or restarting a flood-exposed unit belongs to a pro.
Call a licensed HVAC company when the unit sat in floodwater, when you see electrical damage or scorching, when the system will not restart or blows warm air after the storm, or when you want surge protection, tie-downs, or a pre-season tune-up installed correctly. In peak season, response times stretch, so book early and confirm the company is licensed and insured in Florida before work begins. Browse coastal-city pros in Pompano Beach, Deerfield Beach, Dania Beach, Hollywood, and Hallandale Beach. For pre-season service or storm recovery, our recommended air conditioning partner, Air Nifty, has served the Fort Lauderdale area since 1997.
Frequently Asked Questions
Should I cover my outdoor AC unit during a hurricane?
Only cover it after you have turned the system fully off at the thermostat and the breaker, and use a breathable AC cover or tarp secured with bungee cords rather than airtight plastic. A sealed cover traps moisture and can lead to corrosion, and a covered unit that someone accidentally turns on can be damaged. The bigger priorities are clearing debris away from the condenser and securing loose yard items that could blow into it, which Ready.gov recommends before any storm.
Do I need to turn off my AC before a hurricane?
Yes. Turn the AC off at the thermostat, then switch off both the indoor and outdoor breakers as the storm approaches. Running the system during a hurricane exposes the compressor to power surges, and the greatest surge risk comes when electricity cuts out and then snaps back on. A system that is already powered down cannot be harmed by that flicker. Pre-cool your home a few degrees first so it stays comfortable longer after you shut everything down.
Can I run my AC after a hurricane if it was flooded?
No. If floodwater reached the condenser or the indoor air handler, keep the system off and do not restart it. The CDC advises turning off power at the main breaker and having water-exposed equipment inspected by a professional before use. Water damages motors, wiring, and controls in ways you cannot see, and running a flooded unit can destroy the compressor or create a shock hazard. Call a licensed HVAC technician for an assessment first.
How do I protect my AC from power surges during storm season?
The strongest protection is a whole-house surge protector installed at your electrical panel, which guards the AC and every other appliance in the home. Because that is licensed electrical work, schedule it with a qualified contractor before the season rather than during a warning. A hard-start kit or a surge device at the condenser adds a second layer that a pro can install during a tune-up. Turning the whole system off at the breaker before a storm remains the simplest and most effective safeguard.
When is hurricane season in South Florida?
Atlantic hurricane season runs from June 1 through November 30, according to NOAA, which is when Broward County faces the highest risk of tropical storms and hurricanes. Because that window overlaps the hottest, most humid months, your AC is under the most strain at the same time it faces the most storm exposure. Treat condenser prep, surge protection, and drain cleaning as seasonal maintenance you handle before the first storm forms, not tasks you scramble through as one approaches.
Getting your AC through hurricane season comes down to a short, repeatable routine: secure and shut down before the storm, then inspect for flooding, debris, and electrical damage before you restart. Handle the safe tasks yourself, and lean on a licensed pro for anything involving refrigerant, wiring, or a unit that met floodwater.
