Does Your HVAC System Smell? Moisture Is Likely the CulpritMusty and stagnant smells caused by mold and mildew in your HVAC system can wreak havoc on your senses and your nerves. Air conditioners and heat pumps produce large quantities of water via condensation. To make matters worse, condensation often collects on duct walls when ducts are routed through unconditioned spaces.?

Where to look for smelly culprits

The first place to look for mold and mildew is in the drainage system and evaporator coil of your air conditioner or heat pump. Mold can grow in the drip pan if moisture is allowed to sit. Standing water indicates a drainage issue that must be remedied. The slant may need adjusting, and the drain tube should be cleared and cleaned.

The evaporator coil is another favorite locale for mold to take up residence. Evaporator coils become extremely cold, causing moisture in circulating airflow to condense on the surface. This condensation is normal and necessary in South Florida, but it attracts mold growth if the evaporator and other component surfaces aren?t cleaned regularly.

Mold growth inside the duct system can be more challenging to locate. This is especially true if mold has spread to inaccessible areas. A thorough duct inspection and perhaps a duct cleaning by your HVAC professional?may be necessary to eradicate the problem.

HVAC preventive maintenance

Repairs to your A/C or heat pump?s drainage system, evaporator inspection and cleaning, and duct inspection and cleaning are chores for your HVAC pro. Mold must be removed and repairs performed to prevent mold from returning. Ducts in unconditioned spaces may require insulation to help prevent condensation from occuring, and all drainage issues must be remedied.
