HVAC Mold Testing

Your HVAC moves air through every room in the building. HVAC mold testing confirms whether your ducts and air handler are spreading mold along with it.

Overview

Why HVAC mold testing matters

Cooling coils, drain pans, and duct interiors create a dark, moisture-rich environment where mold has every advantage. Once growth takes hold, the system circulates spores throughout the building on every run cycle. HVAC mold testing pulls samples from supply registers, returns, and the duct walls themselves, confirming whether the air system is generating contamination or carrying it from elsewhere.

HVAC mold testing detects:

  • —Mold colonies forming on coils, drain pans, and duct walls
  • —Elevated spore counts in supply and return air streams
  • —Species patterns pointing to moisture problems in the air handler
  • —Pre and post-cleaning comparisons to verify duct work succeeded

Our certified mold inspectors assess bathrooms, kitchens, laundry rooms, basements, attics, crawl spaces, HVAC components, and any area showing signs of past or current water issues. Thermal imaging and moisture meters identify hidden moisture behind walls and under floors.
Moisture can travel between units through plumbing chases, ceiling cavities, and shared building systems. As a result, a leak originating in one location may affect multiple units before the problem becomes visible to occupants.
Pricing varies based on the size of the property, the scope of testing required, and whether any lab work is included. Most residential mold inspections in North Hills fall within the standard industry range of $300 to $600, with a clear quote provided before any work begins.
