El Niño 2026: 5 Things Bay Area Homeowners Should Check Before the Storms

The forecast predicts that this year, El Niño will be stronger than any storm since 1950. California is said to be affected by it for three months through late December, which means that the time to prepare for the nature’s force is now. Every homeowner in the Bay Area and beyond should run a diagnostic checklist with their heating, plumbing and electrical systems. Believe us, worst time to discover an issue is during a major winter storm.

At Fuse Service, we are happy to help residents to prepare their essentials for severe weather conditions. Here are five most important things to check before El Niño hits.

1. Clean Your Drains and Check Your Plumbing Before the Rainy Season

A storm can reveal hidden issues with your home’s drains. Light showers are almost nothing comparing to El Niño’s destructive power. Before it goes out in full force, check the following:

Yard and landscape drains.
Driveway and patio drains.
Catch basins.
Downspouts and their drainage connections.
Drainage pipes that have previously backed up.
Sewer lines with recurring blockages.

Depending on your piping condition and the causes of blockages, you may ask for these services:

Hydrojet	High-pressure water can remove grease, sludge, and other buildup from suitable pipes.
Drain snake	A mechanical drain snake can break through or remove certain obstructions and restore flow.
Sewer camera inspection	A camera can help identify root intrusion, damaged sections, and recurring blockage locations.

But remember, hydrojetting is not suitable for every pipe type. Consult with the professional plumber before booking this service.

2. Test Your Sump Pump or Install One

For homes with basements, crawl spaces, or below-grade drainage systems, a working sump pump is absolutely essential during wet weather. A sump pump collects water from a sump basin and pumps it to an approved discharge location.

How to Test Your Sump Pump

If your pump’s manufacturer permits a homeowner test, carefully follow the instructions for adding water to the sump basin and confirming that the pump starts and discharges water. Make sure the water level drops and the pump shuts off normally. Do not reach into the basin or handle electrical connections while the equipment is energized. If the pump doesn’t operate correctly, contact a professional. Also, don’t forget exterior drainage — inspect gutters, drainage channels and areas where the water collects.

Don’t have a sump pump? Not to worry. To begin with, not every home needs one normally. But with El Niño coming it is best to know that for sure. You can contact us today and our plumbers will come, evaluate your drainage needs and recommend the right solution. If the solution is to get a sump pump, we can also fully cover its installation before the rainy season arrives.

3. Check Your Furnace or Heat Pump Before the First Cold Night

When the temperature drops and heavy rain arrives, your heating system will be your favorite child. But after months of little to no hearing use, you might discover your furnace or heat pump is not working as it should. Common problems after summer include:

Dirty or clogged air filters.
Thermostat malfunctions.
Ignition or burner problems in gas furnaces.
Electrical connection issues.
Heat pump performance problems.
Blocked condensate drains.

What Should You Check?

Before winter, turn on your heating system and confirm that it operates normally.

Check the thermostat

See that all the settings work properly and the batteries are not dead.

Listen for noises

Any unusual sounds like rumpling or banging are not a good sign.

Replace the filters

HVAC filters should be replaced regularly, ideally every three months.

Schedule a maintenance visit

Regular professional maintenance is the key to keeping your system running efficiently.

4. Inspect Your Electrical Panel and Check for Existing Problems

Heavy storms often mean power outages and electrical hazards. Make sure you are not in the risk area. Warning signs include:

Circuit breakers that trip repeatedly.
Burning smells near the electrical panel.
Buzzing or crackling sounds.
Visible rust or moisture damage.
Flickering lights affecting multiple circuits.
Signs of overheating or discoloration.

Should You Install Whole-Home Surge Protection?

Storms and utility switching events can produce voltage surges that may damage sensitive electronics and equipment. A whole-home surge protective device can help reduce damage from certain transient overvoltages. It does not prevent power outages, eliminate every electrical hazard, or guarantee protection against a direct lightning strike. A licensed electrician can evaluate whether surge protection is appropriate for your electrical system.

Important: Never remove an electrical panel cover or touch wet electrical equipment yourself. If you notice signs of damage, contact a qualified electrician.

5. Check Your Outdoor HVAC Unit Before Heavy Rain

Your outdoor air conditioner or heat pump is designed to operate outside. Rain alone should not shut down properly installed, maintained, and rated outdoor HVAC equipment. However, the area surrounding your outdoor unit can affect its performance and reliability. During the rainy season, leaves, branches, mud, and other debris may collect around the equipment.

What Can Go Wrong With Outdoor HVAC Equipment?

Blocked airflow

Leaves, dirt, and debris around the outdoor coil can restrict airflow and reduce system performance.

Standing water

Poor drainage around the equipment may expose components to excessive moisture or flooding.

Damaged electrical connections

Deteriorated wiring, conduit, or enclosures can create electrical safety hazards.

Blocked condensate drainage

Heat pump or AC condensate drainage problems can lead to leaks or equipment shutdowns.

How to Prepare Your Outdoor Unit

Keep leaves and loose debris away from the equipment and maintain the manufacturer’s recommended clearance. Make sure surrounding drainage directs water away from the unit. If the equipment is located in a flood-prone area, ask an HVAC professional whether additional protection or relocation is appropriate.
