Fighting Tennessee Allergies with Better Indoor Air Quality

Published 2026-03-22 by Airbourne Air Conditioning

Nashville, Knoxville and Memphis regularly land on lists of the worst U.S. cities for allergies. Your HVAC system can be your best defense.

Upgrade your filter

Move from a basic fiberglass filter to a MERV 11–13 pleated filter — but check with a technician first, since older systems may struggle with the added resistance.

Whole-home air purifiers

Media air cleaners and electronic purifiers installed at the air handler clean every cubic foot of air the system moves. UV lights control mold on the coil. See our indoor air quality options.

Control humidity

Dust mites and mold thrive above 50% humidity. A whole-home dehumidifier keeps summer air dry; a humidifier prevents dry, irritated sinuses in winter.

Seal and clean ductwork

Leaky return ducts pull attic dust and insulation into your air. Duct sealing and cleaning fixes the source.

Keep up with maintenance

A clean evaporator coil and drain pan prevent mold growth inside the system. Our maintenance plan covers both seasons.
