Over time, the simple HVAC (heating, ventilating, air conditioning) system has evolved to meet all the varied needs of different homes across the United States. There are these straightforward single-stage heating and cooling systems, and then there are the more sophisticated multi-stage HVAC technologies that can save energy costs. Over the last several years, HVAC systems have evolved into different types including zoned systems, heating systems, humidity control, and cooling systems. Irrespective of the purpose that these systems serve, Mold can establish colonies inside the ductwork. This article will show you the correct way on how to get rid of mold in air ducts.
Mold infestation usually comes with a musty odor. If there is mold in your HVAC system, you should be able to smell the strange musty odor in multiple adjacent rooms. If the mold problem is quite severe, you should be able to spot the growth around the ducts, in the vents and the other parts of the ductwork. The spores are too small for spotting without specialized equipment, and you will not see any other overt signs until the infestation is rampant. In most cases, people have to rely on their sense of smell to detect the presence of this stealthy intruder in their homes.
What causes mold infestation in the HVAC air ducts?
A warm location with high water vapor content is particularly prone to mold buildup within the ducts. Water vapor can form within the duct system when cold air passes through, and when there is high water vapor content in the outside environment, the water droplets usually collect instead of evaporating. It forms the most conducive environment for mold growth. The nutrition for the mold usually comes from dust, dirt, dead skin cells, pollen, and animal dander that collects over months inside the duct along with the water.
What are the signs of mold in air ducts?
Here are a few definitive signs of mold growth within home HVAC systems:
- A strong mildew-like or musty smell throughout the house or at least in a few adjacent rooms.
- Your nose, throat, and eyes feel irritated when you switch on the air conditioning or step inside an air-conditioned room.
- You are experiencing allergic symptoms including a runny nose, rashes, and watering eyes.
- You or your family are suffering from unexplainable headaches that go away when you step outside.
- You feel nausea, fatigue, and dizziness only when you are home.
- You can see the mold growing within the intake vents and around the air ducts and drip pans.
Therefore, if you live in a warm climate and your home smells musty all the time, you have the perfect reason to suspect a mold infestation within the central air conditioning system. You should never wait for the visible signs of infestation to manifest before taking action. You may not be able to see specific sections of your HVAC ductwork from the outside. In that case, you should ask for professional help.
