Musty Smell from AC Vents? It Could Be Mold (And Here’s How to Fix It)

Musty Smell from AC Vents

A strange or musty smell coming out of your air conditioner isn’t something you should ignore. This smell may be due to mold inside the AC. Professional AC mold removal is the best way to ensure the air in your home is clean and safe for your family to breathe. The HVAC experts at Hoover are ready to help. 

Is There Mold in My AC? Common Signs

Air conditioners are the perfect environment for mold to grow. Organic matter can build up in the filter, giving it the damp material it needs to flourish. Here are two of the most common signs of mold inside your air conditioner.

A moldy smell in the air

Most mold has a musty smell that might remind you of old books or wet dirt. This AC mold smell may only be noticeable when the AC is running, but it can fill the entire house if you have a central AC unit. 

Visible mold growth

You may see mold growing on or around your air conditioner or in other areas of your home. Mold can be white, black, yellow, green, or brown in color and hairy, fluffy, smooth, or flat in texture.

Why AC Mold Is a Problem You Shouldn’t Ignore

Several different types of mold can grow inside Troy, Michigan homes. Mold is a living organism, spread through microscopic spores that float through the air until they find somewhere moist to grow. 

Mold can take a few days to start growing, so the faster you take care of the problem, the less likely it is to grow and send mycotoxins into the air. AC mold health effects may include breathing problems and worsening allergies. You may notice stronger asthma reactions, stuffy nose, or red and itchy eyes. In serious cases, you may develop shortness of breath and fever. 

For these reasons, ignoring mold in your air conditioner is never a good idea. Instead, call a professional to safely remove the mold so you can relax knowing your family is breathing clean air. 

DIY AC Mold Cleaning Vs. Calling a Professional

You may want to scrub mold from your walls or under your sink yourself, but call an HVAC professional to address mold issues inside your air conditioner. They have the expertise and the proper tools to safely disassemble the unit, and they’ll know exactly where to look. 

Professionals can quickly identify black mold in your AC, even if you have a central air system with ductwork. Using safe cleaning tools and family-safe solutions, they’ll have your cool air mold-free in a matter of hours. 

Michigan is one of the most humid states in the US, so mold is likely to return if you don’t keep up with maintenance. Schedule routine cleaning and maintenance calls with Hoover and have our certified HVAC experts handle everything for you.
