For Highland Village Homeowners

Highland Village falls within Lewisville ISD, in Denton County, and like the rest of the DFW Metroplex, homes here deal with the same demanding summer heat and occasional winter freezes that make this topic relevant across North Texas. What changes city to city isn't the underlying HVAC principles, it's the mix of home ages and system types we see, and Highland Village has its own particular blend.

Highland Village, zoned to Lewisville ISD, sits along Lake Lewisville with a mostly established, fully built-out housing stock. Lake-adjacent humidity tends to push cooling systems harder through the summer than a similar home further from the water.

Highland Village 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.
