What to Do Next

Step-by-Step Action Plan

Follow these steps before calling a technician — you may be able to resolve the issue yourself.

1

Conduct a Visual Inspection

Begin by visually inspecting your crawl space for any signs of mold, water damage, or pests. Look for standing water, damp spots, and any structural issues.

2

Check for Odors

Take note of any musty odors that may indicate mold growth or moisture issues. Pay attention to areas with little ventilation.

3

Monitor Humidity Levels

Use a hygrometer to measure humidity levels in your crawl space. Ideally, humidity should be below 60% to prevent mold growth.

4

Inspect Insulation

Check the insulation in your crawl space for any signs of dampness or mold. Replace any contaminated insulation to prevent further issues.

5

Assess Ventilation

Ensure that your crawl space has adequate ventilation. If vents are blocked or insufficient, consider adding more to improve air circulation.

6

Evaluate Drainage Systems

Inspect gutters, downspouts, and drainage systems to ensure proper water diversion away from your home’s foundation.

Pro Tip
Always turn off power to the unit at the breaker before inspecting any components. Safety first — even for simple checks.
