Hurricane season stresses every part of a Jacksonville home, but the two systems that are often overlooked are the AC unit sitting outside and the plumbing running underneath everything else. High winds, flying debris, and heavy rain can damage an outdoor condenser in minutes, while flooding and power surges create plumbing and equipment problems that show up days after the storm has already passed. Getting ahead of both now, before a storm is on the radar, makes the difference between a speedy recovery and a multi-week repair project.
Start With Your Outdoor AC Unit
Your condenser sits outside year-round, but hurricane-force winds and debris put a different kind of stress on it than everyday Florida weather. A few simple steps can help protect it.
Secure and Anchor the Unit
Florida building code requires outdoor AC units to be anchored to their concrete pad, and it’s worth checking that those anchors and straps are still solid before storm season ramps up. Loose or corroded anchors can let a unit shift or tip during high winds, which risks damaging the refrigerant lines and electrical connections running to your home.
Protect It From Debris and Power Surges
Covering the top of your unit with plywood or a breathable, heavy-duty cover can help shield it from flying debris, but avoid wrapping the entire unit in plastic, since trapped moisture can cause its own problems. It’s also worth having a surge protector installed on your AC system, since power fluctuations during storms are a common cause of electrical damage to compressors and control boards. Before a storm arrives, switch off the breaker to your outdoor unit entirely if you’re evacuating, which protects it from surges if the power grid becomes unstable.
Give Your Plumbing the Same Attention
While the AC unit deals with wind and debris, your plumbing system faces a different set of risks tied to flooding and storm surge.
Clear Drains and Gutters Beforehand
Slow drains and clogged gutters become much bigger problems once heavy rain arrives, since water has nowhere to go but back toward your home. Clearing debris from gutters and addressing any known drain issues before a storm gives rainwater a clear path away from your foundation instead of pooling around it.
Know Your Main Water Shutoff
If floodwater reaches your home, being able to shut off your main water line quickly can prevent contaminated water from backing up into your plumbing system. Every homeowner should know exactly where that shutoff valve is located well before a storm, not scramble to find it during one.
Protect Outdoor Fixtures
Exposed outdoor faucets, irrigation backflow devices, and exterior plumbing fixtures are vulnerable to both wind damage and flooding. A quick walk around your property to identify anything exposed lets you decide what needs extra protection or a temporary shutoff before a storm arrives.
After the Storm Passes
Once conditions are safe, resist the urge to immediately flip your AC back on if your home lost power for an extended period. Give the system a few minutes before restarting to let any pressure in the refrigerant lines stabilize, and check for obvious damage to the outdoor unit before running it. On the plumbing side, watch for signs of water intrusion around fixtures or in your water heater closet, since flooding damage isn’t always visible right away.
To get through hurricane season with your comfort systems intact, you need to take a few preventable steps before a storm is named, not after. If your AC or plumbing needs an inspection ahead of this season or repair after a storm has already come through, Buehler is ready to help Jacksonville homeowners get storm-ready and stay comfortable through whatever the season brings. You can schedule an inspection online or reach out about emergency plumbing service if you need help after a storm.
FAQs About Hurricane Prep for AC Unites
Should I cover my outdoor AC unit before a hurricane?
Covering the top of your unit with plywood or a breathable heavy-duty cover can help protect it from flying debris, but avoid wrapping the entire unit in plastic. Trapped moisture underneath plastic can lead to corrosion and other issues once the storm passes.
Is it worth installing a surge protector for my AC unit?
Yes, a surge protector is a relatively small investment that can prevent expensive damage to your compressor and control board during power fluctuations, which are common during hurricanes. It’s one of the most cost-effective ways to protect your system heading into storm season.
What should I do with my AC before evacuating for a hurricane?
Turn off the breaker to your outdoor AC unit before you evacuate, which protects the system from power surges if the electrical grid becomes unstable during the storm. Make sure any covers or straps are secure before you leave as well.
