Aprilaire
Exclusively at Trotter Company, we install only the highest-rated DVA (Dehumidification, Ventilation, and Air Filtration) systems to keep your crawl space dry, healthy, and protected year-round. That’s why we trust Aprilaire, an industry leader in moisture control and air quality solutions. Aprilaire systems maintain an optimal 40%–50% relative humidity level in your sealed crawl space, helping prevent mold growth, wood rot, and structural deterioration.
Built for high-capacity performance, Aprilaire dehumidification systems remove over 100 pints of moisture per day with no buckets to empty, automatically draining into a sump pump or gravity drain for seamless, low-maintenance operation. The result is a consistently dry crawl space, improved air quality, and long-term protection home and family.
