Do My Air Ducts Need Cleaning Because There Is Mold Around the Air Handler? Not automatically. The duct system should be inspected when evidence suggests involvement. Mold on a closet wall or platform alone does not justify whole-system duct cleaning. Does the Drywall Around the Air Handler Have to Come Out? Not automatically. The decision […]

Does Particleboard Have to Be Removed if It Is Moldy and Swollen? Often, significantly swollen or delaminated particleboard is difficult to restore because the material has physically deteriorated. Removal may be more practical than attempting to clean damaged material. Does the Drywall Behind the Kitchen Cabinet Have to Come Out? Not automatically. If drywall is […]

Can an Oversized AC System Contribute to the Problem? Potentially. Short cycling can reduce moisture removal even while the home reaches its temperature set point. Can a Dirty Evaporator Coil Cause High Humidity? HVAC performance problems can affect airflow and moisture removal. The system should be evaluated rather than assuming one component is responsible. Can […]

If the AC Drain Line Is Cleared, Is the Water-Damage Problem Finished? No. Clearing the condensate drain stops additional overflow, but drywall, baseboards, flooring, cabinets or framing may still be wet and require drying or remediation. How Does an AC Drain Line Cause Water Damage? Condensation produced by the cooling system normally drains away. A […]

Can a Dirty Filter Contribute to Air-Handler Buildup? Yes. Poor filtration or neglected filters can allow more particulate to accumulate on coils, blowers and cabinet surfaces, although filtration alone does not explain every microbial condition. Can an AC Shutdown Cause Black Growth in the Air Handler? Potentially. Extended loss of cooling and dehumidification can increase […]

Does Mold Around an AC Vent Mean There Is Mold in My Ducts? Not necessarily. Dark spotting around a register can come from condensation, surface dust, air leakage or microbial growth on nearby drywall. The register, boot, accessible duct interior and air handler should be inspected before assuming the entire duct system is contaminated. Why […]

Can an HVAC Company Clean the Air Handler? HVAC contractors can service mechanical components and may perform certain cleaning. When a condition involves significant microbial contamination or building mold remediation, a Florida-licensed mold professional may also be appropriate. Should the Blower Wheel Be Cleaned? If it has significant accumulated debris or contamination, yes. Blower components […]

What If the Mold Is Right Around an AC Vent? Condensation at the register or boot becomes an important possibility. Evaluate humidity, insulation, air leakage and HVAC performance before assuming the ducts are dirty. Does Mold Around an AC Vent Mean My Ducts Need Cleaning? No. Duct cleaning does not correct condensation caused by humidity, […]

Who Performs the Clearance Test? The independent mold assessor typically performs post-remediation verification when it is part of the project. The remediator should not simply declare its own work independently cleared. What Happens if the Post-Test Fails? The remediation area is evaluated to determine why it did not meet the clearance criteria. Additional cleaning or […]

Can a Clogged Drain Cause the Problem? Yes. Poor condensate drainage can create standing water or elevated moisture in and around the air handler. Correcting the drain condition is important to prevent recurrence. Can a Dirty Filter Contribute to Air-Handler Buildup? Yes. Poor filtration or neglected filters can allow more particulate to accumulate on coils, […]

Can a Stucco Crack Cause a Wet Baseboard Inside? Yes. Rain or irrigation can enter through a vulnerable exterior detail and migrate down the wall assembly to floor level. Can Sprinklers Cause the Bottom of an Exterior Wall to Stay Wet? Yes. Repeated irrigation against stucco, windows, doors or penetrations can create or worsen an […]

Should I Put a Dehumidifier in the Closet? A small dehumidifier may reduce local humidity, but first determine whether the home has a broader HVAC/humidity problem or an actual water intrusion. Should I Move Clothes Away From the Wall? Yes. Leaving space for airflow and inspection can help, particularly along exterior walls. Should I Remove […]
