Hurricane-Season HVAC Checklist: Straps, Covers & Surge Protectors

Hurricane strapping keeps the condenser on its pad when the wind arrives — and straps age: corrosion from our salt air, loosened anchors, and code changes since the original install all matter. The pre-season check verifies strap condition, anchor integrity, and compliance with current code, replacing what's rusted and bringing older installs up to standard.

The pad and mounting matter equally: level pads, no hollow spots under feet, and the unit positioned out of debris-fall paths (overhanging limbs are the classic culprit). A wind-thrown unit isn't just a damaged unit — it's a crushed line set, a torn electrical whip, and often a total loss that elevation and strapping would have prevented.

The storm's electrical aftermath kills more equipment than its wind: grid restoration spikes and outage-flicker events destroy boards and compressors in the hours after the rain stops. The whole-system surge protective device installed at the equipment is the defense — clamping the spike before it reaches the expensive components — and pre-season is when it should go in, not post-claim.

Grounding and disconnect condition get verified at the same visit: a surge device on a compromised ground is decoration, and a corroded disconnect is its own storm casualty. The electrical prep is twenty minutes of the appointment and the highest-value twenty minutes in it.

Water is the storm's second weapon: low-parcel equipment in flood zones should already sit on engineered stands above base flood elevation (a replacement-time requirement, worth checking ahead of need), and every unit benefits from drainage attention — pad grading that sheds water, condensate lines routed away from standing-water paths, and no debris dams around the base.

Indoors, the same attention applies to the air handler: condensate drain flushed and treated (a storm-week clog plus a power flicker is a classic ceiling-stain recipe), float switch tested, and the handler's surroundings cleared. Water damage from a storm is bad; water damage from a drain that was already failing is preventable.

The last checklist item is paper: photograph the equipment's current condition (all sides, nameplate, serial numbers), file the model information with your insurance documents, and note the system's pre-season performance. That pre-storm record is what the post-storm claim compares against — 'it worked perfectly before' needs evidence to be worth anything.

And the storm-day plan: know where the disconnect is and how it works, know which breaker is the HVAC's, and remember the post-storm sequence — flooded equipment stays unenergized, documentation happens before cleanup, and the stable-grid restart waits for power that's actually stable. The checklist's last item is the one you hope to never run; it's also the one 2004 taught this town best.
