South Florida homeowners need an AC tune up before hurricane season to catch a weak capacitor, a clogged drain line, or a corroded coil while there's still time to fix it on a normal schedule, not during a storm watch. Homes on canals, near the coast, or still running units older than 10 years carry more risk than the rest, and that risk shows up in June, not November.
- An AC tune up before hurricane season catches problems while a technician still has time to fix them right.
- Hurricane season runs June 1 through November 30, so late May is the window to act.
- Salt air and older R-22 systems fail faster in Palm Beach County and the Treasure Coast after storms.
- A.R. Williams Air Conditioning quotes flat rate pricing before any work starts, with no pressure to decide on the spot.
- Surge protection and a documented pre storm inspection matter more than a filter swap this time of year.
Why this matters for South Florida homeowners
Hurricane season officially runs from June 1 to November 30. That's six months where your AC has to keep running through heat, humidity, and power interruptions, sometimes all in the same week.
Homes built before 2010 in Palm Beach County, Broward County, and the Treasure Coast still commonly run R-22 systems. R-22 production ended in the United States in 2020, which means parts for those older units are harder to source and more expensive when a compressor or coil fails mid storm season.
Coastal homes have a second problem: salt air. Outdoor coils near the water corrode faster than the same equipment ten miles inland, and that corrosion accelerates once a storm pushes salt spray further onto the property. A pre season AC tune up catches early corrosion, weak electrical connections, and drainage issues before they turn into a no cool call in August.
Insurance is the third piece. If your system takes storm damage later this year, having a documented inspection from before the storm makes the claim process faster and harder to dispute.
Clear the area around your outdoor unit
Start with what you can check yourself, no tools required. A blocked or buried condenser works harder than it should and that shortens its life well before a storm ever hits.
- Cut back shrubs and palms to give at least 2 feet of clearance on all sides
- Remove leaves, mulch, and debris piled against the base
- Check that the unit sits level, since a shifted pad restricts airflow
- Look for standing water pooling near the base after rain
Check your circuit breaker and disconnect box
The outdoor disconnect box and the breaker feeding your system are easy to overlook until the system won't start. A cracked or corroded disconnect is a common failure point in coastal homes.
- Open the disconnect box and look for rust or pitting on the contacts
- Confirm the breaker in your panel hasn't tripped or shows scorch marks
- Note whether your electrical panel is original to a home built before 2010
- Flag any burning smell or buzzing sound for a technician, don't investigate further yourself
Test your system on a hot afternoon
Run the system for a full cooling cycle on a day above 85 degrees, not a mild morning. Problems that don't show up at low load will show up when the compressor works hardest.
- Confirm the house reaches your thermostat setting within a reasonable amount of time
- Listen for short cycling, where the system turns on and off more often than it should
- Check that airflow feels even in every room, not just near the air handler
- Watch the outdoor unit for unusual vibration or a fan that hesitates on startup
If anything on this list looks off, that's the point to stop the DIY check and call in a professional rather than guess at a fix.
Schedule a professional pre season tune up
A technician catches what a visual check can't: refrigerant levels, electrical connections inside the unit, and coil condition. A.R. Williams Air Conditioning is a certified Ruud Pro Partner, Carrier Authorized Dealer, and Daikin Comfort Pro, and every tune up comes with flat rate pricing quoted before any work starts.
- Refrigerant level and pressure check
- Electrical connection tightening and testing
- Coil cleaning, especially important on coastal properties
- Capacitor and contactor testing under load
- Drain line inspection and clearing
A pre season AC tune up from A.R. Williams Air Conditioning is the fastest way to know whether your system is ready for hurricane season, not just whether it's cooling today.
Add surge protection before storm season
Power fluctuations during and after storms are one of the more common causes of compressor damage that homeowners never see coming. A whole home or unit level surge protector is cheap insurance against an expensive repair.
- Confirm whether your current system already has a surge protection device installed
- Compare whole home protection against a unit level device for the outdoor condenser
- Check the best surge protection devices for Florida AC systems rated for coastal power grid conditions
- Ask your technician to test the protection device during your tune up, not just install it and leave
Confirm your ductwork survived any roof work
If your roof was patched or replaced after a prior storm, don't assume the ductwork underneath is untouched. Roof repair crews sometimes disturb attic ducts, insulation, or air handler connections without flagging it.
- Check attic ductwork for gaps, crushed sections, or disconnected joints near roof penetrations
- Look for water staining on ducts or the air handler that suggests a leak introduced during roof work
- Review AC maintenance for homes after hurricane roof repairs if your roof has been touched in the last few years
- Ask your technician to inspect duct connections specifically, since it's not part of every standard tune up
Build a power outage plan for your AC
Power outages after a storm are common in South Florida, even in homes that take no direct damage. Knowing how your system behaves during and after an outage keeps you from making a bad situation worse.
- Know your system's restart sequence after power is restored, most need a short wait before cooling resumes
- Understand what running your AC on a generator actually requires before you try it
- Read how to run your AC during a hurricane power outage before you need the answer
- Keep your thermostat settings and system manual in a spot you can find quickly
Check your warranty coverage for storm damage
Most homeowners assume their AC warranty covers storm damage. Most manufacturer warranties don't, and that gap catches people off guard right after a storm when they need the coverage most.
- Pull your warranty documentation and check what's excluded, not just what's covered
- Confirm whether your homeowner's insurance, not the AC warranty, is the actual coverage for wind or water damage
- Review how to check if your AC warranty covers storm damage before you assume you're protected
- Keep your pre season tune up documentation, since insurers often ask for proof of maintenance

Comparing your pre season options
| Option | Best for | Key limitation |
|---|---|---|
| Professional pre season tune up | Homeowners with a system older than 5 years or near the coast | Requires scheduling ahead of peak season demand |
| DIY visual inspection | Newer systems inland, as a first check | Can't catch refrigerant, electrical, or internal coil issues |
| Surge protection installation | Homes that lose power during storms | Doesn't prevent physical storm damage, only electrical surges |
| Ongoing maintenance plan | Homeowners who want year round coverage, not a one time check | Only useful if visits actually happen on schedule |
A professional pre season tune up from A.R. Williams Air Conditioning is the best move for any system older than 5 years or sitting within a few miles of the coast, where salt air speeds up corrosion.
Common mistakes South Florida homeowners make before hurricane season
- Waiting until a storm watch is issued to call. By then, technicians across the region are booked solid and you're choosing from whoever's left, not a company you trust.
- Skipping the outdoor unit's electrical connections. Homeowners check the thermostat and the filter, then skip the disconnect box and breaker entirely, which is where a lot of coastal corrosion actually shows up first.
- Assuming the AC warranty covers storm damage. It usually doesn't, and finding that out after a storm instead of before it costs real money.
- Ignoring an older R-22 system's added risk. These units are more expensive to repair and harder to source parts for, which turns a routine tune up into a bigger decision if something fails.
- Treating a tune up as optional after a mild season. A quiet hurricane season last year doesn't tell you anything about your coil condition or refrigerant levels this year.
FAQ
When should I schedule an AC tune up before hurricane season?
Schedule your AC tune up in late spring, ideally before June 1 when hurricane season officially starts. Booking early avoids the scheduling crunch that hits once storm activity picks up across South Florida.
Should I turn off my AC during a hurricane?
Most homeowners shut down the outdoor unit if winds reach damaging speeds or if the power grid is unstable. Check how to run your AC during a hurricane power outage for the full sequence, since restarting incorrectly can stress the compressor.
Does homeowners insurance cover AC damage from a hurricane?
Homeowners insurance often covers storm related AC damage, but the manufacturer’s warranty usually does not. Confirm which policy actually applies before a storm, not after, since claims move faster with pre storm documentation on file.
How much does a pre hurricane season AC tune up cost?
Cost depends on system age, condition, and what the inspection finds. A.R. Williams Air Conditioning quotes flat rate pricing before any work starts, so you know the number before agreeing to anything.
Can I run my AC on a generator during a power outage?
Some systems can run on a properly sized generator, but undersized generators can damage the compressor. Confirm your system’s starting wattage requirements with a technician before you try it during an outage.
How do I protect my outdoor AC unit before a storm?
Clear debris and vegetation from around the unit, confirm surge protection is installed, and have a technician check electrical connections for corrosion. Coastal homes need this more often than inland properties because of salt air exposure.
Is it too late to get an AC tune up if a storm is already forecast?
A tune up right before an approaching storm is still worth doing if you can get an appointment, though scheduling gets harder as the storm gets closer. Booking in late spring avoids that scramble entirely.
One last thing
R-22 production ended in the United States back in 2020, and homes built before 2010 are still the ones most likely running it. If your system uses R-22 and takes storm damage this season, a repair can turn into a full replacement conversation fast, simply because the refrigerant itself is harder to find. That's worth knowing before June 1, not after a technician tells you mid repair.
