Hurricane season officially starts June 1 — but Tampa Bay homeowners know the Gulf doesn’t wait for the calendar. Before you think about storm shutters and water supplies, ask a simpler question: is your air conditioning system ready?
If you’re coming off a spring tune-up, good. But spring maintenance and hurricane prep aren’t the same thing. Storm season adds a different layer of risk that a routine tune-up doesn’t cover. Here’s what to check specifically before June 1.
Why Hurricane Season Is Different for Your AC
Spring maintenance focuses on efficiency — refrigerant levels, coil cleaning, filter replacement. Hurricane prep adds storm-specific failure points:
- Power surges — When the grid drops and comes back, voltage spikes destroy capacitors, contactors, and control boards. These are the components most commonly replaced after storms.
- Physical damage — Wind-driven debris, flooding, and water intrusion can damage or total your outdoor condenser unit.
- Post-storm demand — After a major storm, every AC company in Tampa Bay is backed up for weeks. The homeowners who prepared in May are cooling down while their neighbors wait.
Pre-Season AC Checklist: What to Inspect Before June 1
Electrical Components (Highest Risk)
This is where storm-related AC failures happen most:
- Capacitors and contactors — These fail under electrical stress. If yours are more than 3–4 years old or flagged in a recent service report, replace them now. An $80 capacitor replaced in May beats a $400 emergency call in August.
- Surge protection — A unit-level surge protector on the disconnect is your best defense against power restoration voltage spikes.
- Disconnect box — The grey box near your outdoor unit should be sealed, mounted securely, and showing no corrosion or moisture intrusion.
Outdoor Condenser Unit
- Clear at least 2 feet of space on all sides
- Remove nearby items that become projectiles in high winds — patio furniture, potted plants, decorative stones
- Verify the unit is bolted to its concrete pad (not just sitting on it)
- Note the unit’s height — in flood-prone areas, elevation matters
Do NOT cover or wrap the condenser while it’s in use. Units need airflow. If you cover it during the storm itself, turn it off at the breaker first.
Refrigerant and Cooling Performance
- Get a refrigerant level check from a licensed tech
- A borderline charge today becomes a breakdown when you’re running the unit 24/7 after a storm
- If a previous inspection noted a possible slow leak — fix it before June 1
Air Handler and Ductwork
- Confirm the air handler area is dry with no moisture, staining, or mold
- Check ductwork connections — loose ducts dump conditioned air into your attic
- Verify the condensate drain is clear; a clogged drain will overflow during extended post-storm AC use
Generator and AC: What You Need to Know
Running your central AC on a generator isn’t as simple as plugging in.
- Most central AC units require 240V and significant startup amperage (2–3x running wattage on startup)
- A standard portable generator cannot handle a central AC system
- Whole-home standby generators can — but only if properly sized with an automatic transfer switch installed by a licensed electrician
Check your unit’s nameplate for RLA (running load amps) to determine generator sizing. Never backfeed power through outlets — this endangers utility line workers. If your generator is portable, prioritize refrigerators, charging, and lights — not central AC.
Pro vs. DIY: Where’s the Line?
Homeowners can handle: replacing the air filter, clearing the condenser area, checking the disconnect box is sealed and dry, shutting off AC at the thermostat and breaker before the storm arrives (30–60 minutes before sustained 45+ mph winds), and doing a post-storm visual inspection before restart.
Call a licensed HVAC tech for: refrigerant check and recharge (EPA-regulated), capacitor and contactor replacement, electrical inspection and surge protector installation, post-storm restart inspection if there’s any doubt about the unit’s condition, and any work involving refrigerant lines or the air handler.
The rule: if it’s electrical or refrigerant-related, call a tech. Everything that’s visible and doesn’t involve refrigerant loop components is fair game for a prepared homeowner.
Before and After the Storm: Quick Reference
Before the storm arrives:
- Turn off AC at thermostat and breaker 30–60 minutes before high winds
- Remove or secure items within 3 feet of the condenser unit
- Save your HVAC company’s number: (813) 358-4591
After the storm, before restarting:
- Walk outside and visually inspect the condenser for debris, dents, or standing water
- Check the disconnect box — if it was flooded, do not power on
- Wait at least 30 minutes after power restoration before turning AC back on
- Call us if you hear grinding, squealing, or the unit runs but doesn’t cool
