El Niño Ready starts with a simple step: checking your systems before wet weather puts them to the test. For San Diego homes and businesses, preparing now can help address existing problems before they become urgent repairs.
NOAA’s September 2026 outlook reports that El Niño is strengthening. While that does not guarantee heavy rain at every property, it makes seasonal preparation a timely priority.
From heating maintenance to plumbing inspections, here’s where to start.
Schedule HVAC Maintenance Before Winter
Don’t wait for the first chilly evening to find out your heating system needs attention. Schedule an inspection, especially if you’ve noticed unusual noises, uneven temperatures, or trouble starting the system.
Ask your HVAC technician to check:
- Heating operation and thermostat settings
- Air filters and airflow
- Electrical connections and equipment condition
- Condensate drains, where applicable
- Any existing performance concerns
For businesses, scheduling service ahead of time also gives property managers more flexibility to coordinate access and minimize interruptions.
Check Around Outdoor Equipment
Before wet weather arrives, look around outdoor HVAC units for leaves, loose debris, and signs of standing water. Keep the surrounding area clear and maintain the clearance required by the equipment manufacturer.
If water regularly collects near a unit, have the drainage issue evaluated. Rooftop equipment should be inspected by qualified professionals rather than accessed without the proper training and equipment.
Avoid wrapping or covering operating equipment unless the manufacturer specifically permits it.
Address Plumbing Warning Signs
Slow drains, recurring clogs, and unexplained leaks deserve attention before the weather changes. An existing plumbing problem can be disruptive at any time, particularly when service access becomes more difficult during a storm.
Watch for:
- Drains that repeatedly empty slowly
- Gurgling toilets or drains
- Persistent sewage odors
- Water stains or visible leaks
- Recurring backups
These symptoms do not all have the same cause. A plumbing inspection can help determine whether the issue involves a fixture, drain, or sewer line and what repair is appropriate.
Review Drainage Around Your Property
Stormwater drainage and your building’s plumbing serve different purposes. Preparing for wet weather means checking both.
Have gutters, downspouts, and exterior drainage areas checked for debris or blockages. If your property has a sump pump or another drainage pump, arrange an operational check before it is needed.
For commercial properties, include loading areas, courtyards, and low spots where water has collected during previous storms. Document recurring issues so the appropriate maintenance professional can evaluate them.
Check Water Heaters and Mechanical Areas
Look for visible leaks, corrosion, or moisture around water heaters and accessible mechanical equipment. Keep service areas clear so technicians can reach equipment when needed.
In a business or shared building, make sure the responsible staff know where water shutoff valves are located and whom to contact for urgent repairs. Report changes in hot water performance rather than waiting for a complete loss of service.
Know What to Do After Flooding
If floodwater reaches HVAC equipment, a water heater, or electrical components, arrange a professional inspection before using the affected equipment again. Do not enter standing water to reach switches or shutoff valves.
Monitor local weather alerts and follow official flood safety guidance when conditions change.
