September Home Safety Checklist: Hurricanes
September 10 is the statistical peak of hurricane season — and the start of radon testing season
Data source: NOAA, NWS, EPA, DOE, CPSC Last updated: June 2026
Why September Is a Critical Month for Home Safety
September is a month of transitions — and each transition creates specific hazards. Hurricane season reaches its statistical peak, the heating season begins in northern states, and the EPA's recommended radon testing window opens. Proactive homeowners use September to address all three simultaneously.
NOAA records show that September has produced the most billion-dollar hurricane disasters of any month in the past 40 years. At the same time, the transition from cooling to heating season means HVAC systems are switching modes — the ideal time for inspection and maintenance.
Hurricane Season Peak
September 10 is the climatological peak of Atlantic hurricane season. If you live in a hurricane-prone area, your preparation should already be complete — September is about maintaining readiness and monitoring.
September Readiness Check
- Verify emergency water supply — check expiration dates, replace any water stored more than 6 months ago. FEMA recommends 1 gallon per person per day for 7 days in hurricane zones
- Test backup power — run your generator under load for 15 minutes. Check fuel supply and fuel stabilizer
- Confirm sump pump and battery backup function — fall storms combine hurricane rainfall with leaves clogging drains
- Review evacuation plan — including water utility shut-off procedures. Know where your main water valve is
- Clear gutters of early fall leaves — leaf-clogged gutters during hurricane rainfall direct water into foundations
Post-Hurricane Water Safety
If a hurricane or tropical storm affects your area:
- Do not use tap water until your utility confirms it is safe — storm surge, flooding, and power outages can compromise treatment plants
- If on a well, assume contamination after any flooding. Shock chlorinate and test before using
- Boil-water advisories may last days to weeks depending on damage severity
- Document all water damage photographically before cleanup — required for insurance claims and FEMA assistance
Fall Furnace Preparation
September is the optimal month for heating system maintenance. HVAC companies have availability, pricing is lower, and there is time to address any issues before cold weather arrives.
Professional Furnace Inspection
A professional inspection should include:
| Check | Why It Matters | Risk If Skipped |
|---|---|---|
| Heat exchanger integrity | Cracks leak carbon monoxide | CO poisoning — leading cause of winter CO deaths |
| Burner and ignition | Dirty burners reduce efficiency | Higher bills, potential furnace failure |
| Blower motor and belt | Worn belts fail, reducing airflow | Uneven heating, frozen coils |
| Gas connections | Leaks at fittings and valves | Fire/explosion risk |
| Thermostat calibration | Ensures accurate temperature control | Wasted energy, comfort issues |
| Flue/vent inspection | Blocked vents trap CO inside | CO poisoning |
DIY Pre-Heating Season Tasks
- Replace furnace filter — start the heating season with a fresh filter (MERV-11 minimum for allergen control, MERV-13 for smoke and fine particles)
- Test all CO detectors — press test buttons, replace batteries, and replace any units older than 5–7 years
- Clear vents and registers — vacuum supply and return registers, remove furniture or objects blocking airflow
- Test the thermostat — switch to heating mode and verify the furnace activates and produces warm air within 5 minutes
- Inspect the flue pipe — visible from the furnace to the chimney/wall exit. Look for rust, disconnections, or gaps
- Bleed radiators (hydronic/boiler systems) — air pockets reduce heating efficiency and create cold spots
Radon Awareness & Testing
September marks the start of the EPA's recommended radon testing season. Testing now gives you maximum time to install mitigation if needed before peak winter radon levels.
Why Test Now
- Closed-house conditions are beginning — windows closing, heating systems running, creating negative pressure that draws radon from soil
- September results establish a baseline before winter levels peak (winter radon averages 60% higher than summer in the same home)
- If mitigation is needed, September testing allows installation in October–November — before the January peak
- January is National Radon Action Month — testing now means you have results in time to act during the awareness campaign
Radon Testing Action Plan
- Check your ZIP code's radon zone on ZipCheckup — Zone 1 (highest risk) counties have predicted average indoor levels above 4 pCi/L
- Purchase a long-term test kit ($20–$40) for the most accurate reading, or a short-term kit ($15–$30) for faster results
- Place the test on the lowest livable level, away from windows and exterior doors
- Mail to the lab after the testing period and compare results to the EPA action level of 4 pCi/L
- If above 4 pCi/L, contact a certified radon mitigation professional — systems cost $800–$2,500 and reduce levels by 80–99%
Radon & Real Estate
If you are buying or selling a home in fall:
- Buyers should request radon testing as part of the home inspection
- Sellers in Zone 1 areas increasingly pre-test and mitigate to avoid deal delays
- Radon mitigation systems are a strong selling point — similar to a new roof or HVAC system
Water System Winterization Preview
September is early for full winterization in most of the country, but starting now prevents the October rush.
- Drain and disconnect outdoor hoses — left connected, they prevent water from draining back into the pipe, causing freeze damage
- Locate and test outdoor faucet shut-off valves — interior shut-offs allow you to drain exterior pipes
- Insulate exposed water pipes in crawl spaces, garages, and attics — foam pipe insulation is $0.50–$2.00 per foot and prevents the most common freeze failures
- Flush the water heater if you did not in March — fall is your second-best opportunity before winter's heavy demand
- Check water heater temperature — confirm 120°F setting (EPA recommendation)

Frequently Asked Questions
Why is September the most dangerous month for hurricanes?
NOAA data shows that September 10 is the climatological peak of Atlantic hurricane season. September has produced more Category 4 and 5 hurricanes than any other month, including Katrina (2005), Irma (2017), Maria (2017), and Ian (2022). This is because sea surface temperatures in the tropical Atlantic and Caribbean reach their annual maximum in September (82–86°F), providing the energy that fuels major hurricanes. 40% of all U.S. hurricane landfalls since 1851 occurred in September.
When should I schedule a furnace inspection?
Schedule furnace inspection in September, before the heating season rush. By October, HVAC companies in northern states are booked 2–4 weeks out. A professional inspection includes heat exchanger integrity check (cracked heat exchangers leak CO), burner and ignition system cleaning, blower motor and belt inspection, gas leak testing, thermostat calibration, and ductwork assessment. Cost is typically $80–$150 — a fraction of the $3,000–$7,000 cost of an emergency furnace replacement in January.
Why is September the start of radon testing season?
September begins the closed-house testing period recommended by the EPA. As temperatures drop, homeowners close windows and rely on heating systems, creating the sealed conditions where radon accumulates to its highest indoor levels. The EPA and the National Radon Action Plan designate September through March as the optimal testing window. Additionally, January is National Radon Action Month (designated by the EPA), and testing in September gives homeowners time to install mitigation systems before peak winter radon levels.
How do I prepare my home's water system for the heating season?
Before heating season: drain and insulate outdoor faucets and hose bibs, check water heater efficiency (flush sediment, inspect anode rod, verify 120°F setting), insulate hot water pipes in unheated areas to prevent freezing and reduce heat loss, test the temperature-pressure relief valve, and if you have a boiler/hydronic system, check pressure gauges and bleed air from radiators. These steps prevent frozen pipes, reduce energy costs by 10–15%, and extend equipment life.
