When stale odors start to creep into your home from your ductless AC system, it’s a sign of an HVAC problem that needs to be addressed. If left untreated, stale smells could signal that mold and mildew are growing within your ductwork and are being circulated throughout your home. Inhaling these spores can cause health problems including respiratory issues, allergies, and more serious conditions like asthma.

How to Eliminate Bad Odors in Ductless AC Systems

To maintain a comfortable and fresh environment, it’s important to eliminate bad odors in ductless ACs, ensuring your air conditioning system remains efficient and odor-free. it’s recommended that homeowners try several different DIY odor-removal strategies before seeking professional services for a complete inspection, cleaning, and remediation of their ductwork. One popular solution is the use of activated charcoal filters, which can be inserted into a standard air filter to absorb and neutralize foul odors as they pass through the ductwork. These filters are available in a variety of sizes to accommodate most types of HVAC units, making them a versatile option for eliminating bad smells from almost any home’s air conditioning system.

Other odor-fighting options include mixing baking soda with water until it reaches a paste-like consistency and applying it directly to your air conditioner’s air filters or interior components. The absorptive properties of baking soda will trap and deodorize musty odors over time as the airflow through your ductwork circulates. If your odor problem is concentrated in the drain line or around the unit itself, you can also spray a mixture of equal parts vinegar and water to flush out any debris that has accumulated in these hard-to-reach areas.
