Midlothian 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.

Does this apply to homes in Midlothian specifically?+

Yes. The guidance in this article applies to residential HVAC systems throughout Midlothian and the rest of our service area. If you want a read on your specific system, call us at (817) 935-8540 or request an estimate and mention you're in Midlothian.
