When the air conditioner kicks in, do you get a whiff of an odd odor you just can’t pinpoint? Perhaps the stink of oldness lingers in the air.

That could be a telltale sign of air conditioner mold growing within your home’s ductwork. Attack the mold before it gets a chance to flourish.

Here is a breakdown of the four key signs that mold may be lurking in the depths of your heating and air conditioning unit system.

1. The Smell of Mildew

One of the best ways to detect mold in your home’s air ventilation system is to trust your nose.

If you smell a musty odor in several rooms of your house, that is a sign something is growing inside the vents. HVAC mold is difficult to see unless you start crawling inside your home’s air ducts.

It’s best to do a sniff test while the air conditioning is running.

2. Allergy Flare-ups

Many allergy sufferers are sensitive to a buildup of dust and other small particles in the air. That goes for mold spores as well.

If you’re noticing that family members are experiencing frequent breathing problems, that may be a sign that mold spores are triggering allergic reactions.

Having mold in air ducts could cause coughing, sneezing, or red itchy eyes. Other telltale signs: fatigue and dizziness and nausea.

Make consulting with a professional in heating and air conditioning system repairs a priority. They can evaluate the indoor air quality in your home.

Few homeowners have the proper tools or experience in how to clean mold from air conditioner ventilation systems.

3. Mold on Air Duct Vents

One of the obvious signs of mold living inside your home’s air duct system is seeing the fungus patches on the vent grates.

Take a look at the air duct vents throughout the house. Open the grates and remove the air filter. Mold spores appear as splotches of black, green, or white patches.

For a thorough duct system check and mold removal, contact a specialist for an evaluation.

4. Mold in the Air Conditioner Unit

Another spot to check for signs of mold in air conditioner systems is on the evaporator coils.

Mold and mildew love a moist environment. One place where condensation tends to build up is inside your air conditioning air handler. Take a peek at the evaporator coils to see signs of mold growth.

Black mold in air conditioner units is a definite sign that it’s time to call in the experts.
