5 Signs Your HVAC System Needs Immediate Attention

Water damage can happen suddenly—from burst pipes and leaking appliances to heavy rain or flooding. What you do within the first 24 hours can make the difference between minor repairs and major structural damage.

This guide walks you through exactly what to do in the first 24 hours after water damage, helping you protect your home, health, and finances.

Step 1: Ensure Safety First (Hour 0–1)

Turn off the main water supply if the source is internal

Shut off electricity in affected areas

Avoid standing water near electrical outlets or appliances

Wear gloves, boots, and protective clothing

Step 2: Stop the Source of Water (Hour 1–2)

Burst or leaking pipes

Overflowing appliances (washing machine, dishwasher)

Roof leaks

HVAC system issues

Step 3: Document the Damage (Hour 2–4)

Take clear photos and videos of all affected areas

Capture damaged furniture, walls, floors, and ceilings

Do not discard damaged items until approved by insurance

Step 4: Remove Standing Water (Hour 4–8)

The longer water sits, the deeper it penetrates materials.

You can start with:

Wet/dry vacuum

Buckets and mops

Towels for small areas

For large-scale flooding, professional water extraction equipment is far more effective.

Step 5: Begin Drying and Ventilation (Hour 8–16)

Drying prevents mold and secondary damage.

Open windows and doors (weather permitting)

Use fans and dehumidifiers

Remove wet rugs, cushions, and fabrics

Elevate furniture legs to allow airflow

Step 6: Prevent Mold Growth (Hour 16–24)

Mold can start growing sooner than most homeowners realize.

Remove wet drywall, insulation, or carpeting if heavily soaked

Disinfect hard surfaces with approved cleaners

Keep humidity below 50%

Watch for musty odors or discoloration

What NOT to Do After Water Damage

Do not ignore minor water damage

Do not use regular vacuums on standing water

Do not wait days to seek help

Do not assume areas are dry without proper testing

Water damage is stressful, but fast, informed action can minimize long-term consequences. The first 24 hours are your window to prevent mold, reduce repair costs, and protect your property.
If water damage has affected your home, act immediately—your future repairs depend on it.
