Lewisville FAQ

What's a reasonable indoor humidity level to aim for?+

Most guidance points to somewhere in the 30 to 50 percent relative humidity range for comfort and to discourage mold and dust mite growth. Above that range for extended periods is where comfort and air quality both start to suffer.

Will just running the AC fan constantly help with humidity?+

Not really, and it can actually work against you. Running the fan continuously on "On" rather than "Auto" can re-evaporate moisture that already condensed on the coil back into the air stream between cooling cycles, working against dehumidification rather than helping it.

Is this guide relevant for Lewisville homes in Denton County?+

Yes, this applies to homes throughout Denton County, including Lewisville. If you'd like this looked at for your specific address, call (817) 935-8540 and mention your ZIP code.
