Tips To Spot Molds In Ac Ducts

HVAC ducts and the HVAC components have often been found to be prime places where molds actively breed and grow. You will see back patches or thread or dot- like structures at the interior surfaces of the ducts, evaporator coils, or drip pans. Sometimes molds are invisible. How to detect them in that case? Well, let’s see-

• Remember humidity is the life-blood for mold to thrive. If there is humidity in the house, molds can grow. So if your house is humid, buy a dehumidifier to purge off the excess moisture from the room air.

• Inspect your house regularly for possible mold growth in likely areas. As for ducts look into all registers, visible duct work, evaporator coils, and AC/furnace drip pans. Look for mold and fungus is the A/c drain. Check for condensation outside the vents. A possible sign of mold is strange discoloration at the vents. Conduct this inspection every month to detect signs of molds.

• All types of molds are not visible or they may grow in remote areas of duct. In such cases look for musty smell. It gives off a strong smell that spreads throughout the house. The molds as they grow give out a pungent gas which creates this odor. In case you sense a smell, turn off your system and wait for 10 to 20 minutes, and then turn it back on. If the smell mitigates when the system is off and becomes stronger when it on, it’s a sign of active mold growth within the duct and HVAC parts.

• You strongly suspect of mold growth in your duct, you can also call professional mold tester. You can also send a sample of a patch that you suspect to b molds to a nearby lab to get their confirmation. Thy will confirm it for some charges. If they confirm it, call an AC ducts cleaning service to come and carry out appropriate treatments to terminate the growth for good. But remember these treatments should be done only after the ducts have ben cleaned thoroughly.
