Addison FAQ

Is a musty AC smell a health concern?+

It can be, particularly for household members with allergies, asthma, or other respiratory sensitivities. Mold and mildew growing inside an HVAC system isn't something to just live with long-term, it's worth having identified and addressed.

Will an air freshener or vent-clip deodorizer fix this?+

It can mask the smell temporarily, but it doesn't address the actual moisture or mold causing it. If the underlying cause isn't resolved, the smell typically returns, sometimes along with worsening air quality.

Do you see this issue often in Addison?+

It comes up regularly across our Addison service calls, alongside the rest of Carrollton-Farmers Branch ISD and Dallas ISD. Call (817) 935-8540 if you'd like us to take a look at your specific system.
