Hurricane Prep for HVAC + Plumbing

Pre-season (May/June): install surge protector ($469), test hurricane tie-downs, schedule a Home Therapy Club tune-up ($20/mo), check sump pump if applicable.

24-48 hours before: photograph systems, fill tubs, turn off AC + outdoor breaker as storm approaches.

After storm: before restarting AC, check outdoor unit for debris + damage. Don’t run submerged condensers. Call us for post-storm inspection if any damage visible.

Most Tampa homeowners wait until the cone of uncertainty lands on Hillsborough County before they start prep. By then, hardware stores are empty and it is too late to schedule a surge protector install. Here is the timeline we use with our own customers, built on 9 years of storm calls across Tampa Bay.

Pre-Storm: 48 Hours Before Landfall

Check that your whole-home surge protector LED is green (not red or off). Verify hurricane tie-down straps are tight and not corroded. Test your sump pump by pouring a 5-gallon bucket into the pit and confirming it activates. If you are in a Category 3 or greater cone and live in a flood zone, drain the water heater tank to prevent contamination if floodwaters reach it. Stock generator fuel now, not 12 hours before landfall when every gas station has lines. Clear all debris within 20 feet of the outdoor condenser. Photograph every HVAC and plumbing system with model and serial numbers visible, save to cloud storage.

Storm Day: 0 to 12 Hours Before and During

If the City of Tampa issues a boil-water advisory, shut off your main water supply at the street. Flip the outdoor AC breaker OFF before the first hurricane-force gusts arrive. The biggest surge damage in Tampa Bay storms happens mid-event when transformers fail under wind load, not after the storm passes. Close all interior shutoff valves for pool equipment, irrigation, and outdoor spigots. Elevate valuable furniture on blocks if you are in a Zone AE or VE flood area. Move portable dehumidifiers and plug-in appliances to a safe interior location.

Post-Storm: 0 to 72 Hours After

Do NOT flip the AC breaker back on until you visually inspect the electrical panel and the outdoor unit. Look for burnt smell at the air handler, melted wiring near the breaker, debris inside the condenser cabinet, and water intrusion above the concrete pad. Test the condensate drain by pouring a cup of water into the drain pan, it should flow freely. If municipal water was disrupted, flush your water lines for 3 to 5 minutes before drinking. Run hot water for 5 minutes to confirm the water heater survived without airlock or sediment stir-up.

Here is the single biggest mistake Tampa homeowners make: they buy a 7,500W portable generator, plug it into the house with an interlock kit, then discover their 4-ton AC will not start. Startup surge is not running wattage, and most generators are sized wrong for cooling load.

Soft-Start Kits: The Tampa Workaround

A soft-start kit ($999 installed for the EasyStart 368) cuts AC startup surge sharply. A 4-ton AC that would normally need 18,000W surge drops to around 6,300W surge, which a 7,500W portable generator can actually handle. For most Tampa homeowners, a soft-start kit is the single highest-value hurricane upgrade, cheaper than a bigger generator and lets you run the AC off what you already own.

Interlock Kit vs Transfer Switch vs Whole-Home Standby

Interlock kit: $400 to $800 installed, manual breaker swap, cheapest code-compliant option. Transfer switch: $1,500 to $2,500 installed, covers pre-selected circuits, no main-breaker juggling. Whole-home standby (Generac, Kohler, Briggs): $8,000 to $14,000 installed for a 14-22kW natural gas unit, auto-starts within 30 seconds of outage, runs unlimited on utility gas. For most Tampa Bay single-family homes under 2,500 sq ft, an 18kW whole-home unit is the sweet spot.

More AC systems die from wrong-order restart than from the storm itself. Follow this sequence every time.

1. Visual inspection first. Walk to the outdoor unit. Check for impact damage, debris inside the cabinet, water above the concrete pad, bent fins, or displaced refrigerant lines.
2. If submerged, stop. Water above the pad level means potential internal contamination. Do not restart. Call us for a FREE diagnosis.
3. If intact, flip outdoor disconnect ON first, then the breaker in the panel. If the unit was off for 24 or more hours, wait 15 minutes before starting. This lets compressor oil settle back into the sump.
4. At the thermostat, switch to COOL and set 2 degrees below room temperature. Do not drop it 10 degrees, the compressor does not run harder to cool faster.
5. Listen for normal startup. You should hear 5 to 10 seconds of contactor clicking, then a steady compressor hum. Screeching, rapid clicking, or silence followed by breaker trip means something failed during the storm.
6. No cooling after 15 minutes? Shut off at the thermostat and call. Most post-storm failures are blown capacitors, failed contactors, or surge-damaged control boards, all diagnosable same-day.
7. Check the indoor condensate drain. If the system sat off during an extended outage, the drain line can grow algae that plugs the drain. Look for pooled water near the air handler.
8. Let it run one hour, then measure. Normal Tampa post-storm recovery on a properly sized 4-ton system is roughly 1 degree drop per 10 minutes indoors. Slower than that means a problem.
