Mold Inspection, Mold Testing & Air Quality Testing for HVAC Systems
Keep your air clean at the source, where it matters most. Every day, your air conditioning system and ductwork move thousands of cubic feet of air throughout your home or business. If mold is present in coils, drain pans, insulation, or duct liners, those spores can be pushed into every room you breathe in. What looks like a simple comfort system can quickly become a hidden distribution channel for allergens, irritants, and microbial growth. Mold Shark provides licensed, independent HVAC mold testing designed to uncover these issues before they escalate.
TEST RESULTS IN
24-48 HOURS
Our services cover homes, condos, offices, and commercial properties across Broward, Palm Beach, Martin, St. Lucie, Indian River, and Brevard Counties. We use advanced tools like thermal imaging, moisture meters, and InstaScope® to locate and confirm contamination. Each inspection is carefully documented with photos, lab results, and clear findings. Unlike remediation companies, we do not perform cleanup, ensuring our reports remain unbiased and defensible. With Mold Shark, you get honest answers, actionable recommendations, and peace of mind that your air system is truly safe.
What HVAC Mold Testing Covers
Your HVAC system is more than a box in a closet; it’s a network that can move contaminants to every room. We examine the air handler cabinet, blower housing, and evaporator coil for biofilm, staining, and dust mats. Drain pans and condensate lines are checked for standing water, clogs, and microbial growth. Cabinet insulation and gaskets are inspected for dark spotting, deterioration, or musty odor. We evaluate supply and return plenums for visible growth, debris buildup, and airflow issues. Duct liner and the first runs of trunk and branch ducts are assessed where feasible access exists. Supply registers and return grills are inspected for flecks, streaking, and residue that can indicate dispersion. Surrounding spaces like closets, attics, or garages are reviewed for moisture sources that raise humidity.
When to Test & Common Triggers
Test the HVAC when musty odors appear as soon as the system turns on. Visible flecks or dark streaks at vents suggest dispersion and warrant sampling. Allergy or asthma flare-ups that improve away from the building are strong indicators to investigate. Any drain pan overflow, line clog, or water intrusion near the handler merits immediate testing. After renovations or duct work, testing verifies that dust and humidity spikes didn’t create new growth. Before a real estate transaction, HVAC testing reduces surprises and supports negotiation. Following remediation, targeted HVAC sampling confirms the system won’t re-seed the structure. Properties with infants, elderly occupants, or immune-sensitive individuals benefit from proactive checks. Short-cycling, poor dehumidification, or clammy rooms can signal underlying moisture conditions. If the air feels “off,” HVAC mold testing provides objective proof and a path to resolution.
How We Test the HVAC System
We begin with a focused interview to understand odors, symptoms, recent maintenance, and water events. Moisture and humidity readings are taken around the air handler, drain pan, and adjacent building materials. Thermal imaging is used as needed to flag hidden moisture near chases, boots, and ceiling lines. Air samples are collected at key supply registers and in nearby rooms to compare system output to background levels. Surface samples from coils, pans, and cabinet insulation are taken when growth indicators are present. InstaScope® screening helps locate hot spots in real time and refine where lab samples are most meaningful. Chain of custody is maintained for every cassette and swab to preserve data integrity. Outdoor baseline sampling is performed when appropriate to contextualize indoor counts. All equipment is calibrated and used per manufacturer and industry guidance. The result is a targeted, evidence-driven sample set rather than guesswork.
