Seasonal readiness · Protect the household

Prepare the appliance before the weather tests it.

Surges, interrupted power, wind-driven rain, blocked drains and unsafe restart decisions can turn a weather event into appliance damage. A short preparation routine reduces avoidable risk.

Step 1

Match protection to the appliance

A small plug-in surge strip is not the answer for every load. Air conditioners, refrigerators and large appliances may need appropriately rated protection, time-delay restart or an electrician's review of the circuit.

  • Confirm appliance voltage and frequency.
  • Use protection rated for the equipment and installation—not a generic extension lead.
  • Keep plugs, outlets and disconnects free from heat damage or looseness.
  • Ask a qualified professional when hard-wired equipment or panel protection is involved.

Step 2

Prepare for wind and heavy rain

Outdoor AC units need clear airflow, secure mounting and drainage that does not send water into the building. Loose objects nearby can become impact hazards during severe weather.

  • Clear leaves and debris without bending coil fins.
  • Check that the outdoor unit and lines are secure.
  • Clear condensate drains and report leaks early.
  • Move loose objects away from outdoor equipment.

Keep in mind: Do not cover or obstruct operating equipment. Follow manufacturer and technician instructions for shutdown and storm preparation.

Step 3

Handle outages and restart safely

After an outage, the supply may not be stable immediately. Compressor equipment can also need time before restarting. Follow the appliance instructions and any installed time-delay protection.

  • Switch off or disconnect sensitive equipment when it is safe to do so before expected instability.
  • Wait for stable power and the required delay before restarting compressor equipment.
  • If there is water entry, burning smell, unusual sound or damaged wiring, do not energize the appliance.
  • Never operate a fuel-burning generator indoors, in a garage or near openings into the home.

Step 4

Document before and after

A few clear records make service and warranty conversations faster. Photograph existing condition where appropriate and keep purchase, model, serial and service documents available away from flood risk.

  • Save model and serial numbers.
  • Keep receipts, warranty terms and prior service references.
  • Photograph visible storm damage before moving equipment when safe.
  • Use Delta's service form to share the issue and up to three useful photos.
