INDOOR AIR QUALITY IN HATTIESBURG · WHY LOCALS CALL KEITH'S

Whole-home solutions that actually match Coast conditions, not one-size-fits-all sales pitches. That standard applies whether you're in Downtown Hattiesburg, Oak Grove, or anywhere else in Hattiesburg.

Hattiesburg is our largest inland market. Winters here are noticeably colder than the Coast, so heat pump and furnace demand is much higher year-round. Student rentals near USM and William Carey drive volume for smaller repair jobs and quick turnarounds. Commercial demand from restaurants, retail near Turtle Creek Mall, and medical near Forrest General Hospital. Newer construction in Oak Grove skews standard efficient residential.

Indoor Air Quality in Hattiesburg covers these ZIP codes: 39401, 39402, 39406. We service homes near The University of Southern Mississippi, William Carey University, Downtown Hattiesburg, and every neighborhood between.

QUESTIONS ANSWERED.

Which IAQ product actually matters on the Gulf Coast?

Whole-home dehumidifier, first. Coast humidity is the source of most IAQ problems: mold, mustiness, dust mites, off-gassing. Solve humidity, most of the other symptoms fade. UV and HEPA are optional add-ons after dehumidification is handled.

What humidity level should I aim for?

45% to 55% relative humidity indoors. Above 60% invites mold and dust mites. Below 30% dries out sinuses and wood. Coast homes often sit at 65-75% without whole-home dehumidification, which is why the mildew smell shows up.

Does UV really kill viruses and bacteria?

Properly sized UV-C in the airstream reduces microbial load, yes. It's not magic and it doesn't replace filtration. We install both UV and media filters together for full-spectrum reduction.
