How uncommon is it? Well, this great article about Dirty Socks Syndrome written for Air Conditioning, Heating & Refrigeration News estimates that it affects up to 2% of all air conditioners in the South. So not super common, but much better odds than winning the lotto – except this prize nobody wants to win!
To give you an idea of what that looks like, census numbers estimate that there are 1,533,854 homes in South Carolina, and 87% of them have central heating and air. If just 2% of those homes are affected, that means as many as 26,689 people could experience this unpleasantness per season!
So now that we know what it is, what can be done about it? You may think that a good duct cleaning is in order, but sadly, while this microbial growth CAN get into your ductwork, it ultimately starts in the evaporator coil, and the action needs to be taken there – time to call a professional!
The first step to getting rid of the smell is actually preventing it from happening in the first place – this is one of the many benefits of having an annual maintenance contract. By cleaning the evaporator coil and treating the drain line, this smelly problem can hopefully be prevented.
But sometimes the most diligent care isn’t enough, and bacterial growth can still occur. It can be next to impossible to get rid of through annual cleanings, and more aggressive measures are required. This growth can also be especially harmful to anyone with respiratory issues, those who have compromised immune systems, and those homes with children with developing lungs.
This is where indoor air quality (IAQ) products come in. These accessories, when installed into a new or existing HVAC system, can kill any existing mold and mildew and keep any new growths from forming.
A trained HVAC technician can recommend and install a variety of IAQ products to help keep your heating and cooling system clean and odor-free.
Additionally, ultraviolet lights installed in the evaporator coil will kill any current growth and inhibit any future growth. Ionizers can help also help to kill any microbial contaminants.
So if your HVAC system smells musty, now you know why. But don’t cry or panic, the solution can be as simple as having your heating and cooling system serviced and cleaned, or if that isn’t quite enough and the musty smell comes back, consider adding an indoor air quality product to supplement.
