Trane 1.5-2.5 Ton 18000-30000 BTU Multi-Speed Air Handler Daleville

Trane 1.5–2.5 Ton Multi-Speed Air Handler (Model 5TEM4B03AC31S)

The Trane 5TEM4B03AC31S air handler delivers reliable, energy-efficient comfort in a compact and flexible design. Supporting capacities from 18,000 to 30,000 BTU/h (1.5 to 2.5 tons), this air handler is built to match a wide range of residential applications and seamlessly supports next-generation R-454B refrigerant. This makes it a smarter, low-GWP choice for environmentally conscious homeowners, reducing the system's carbon footprint without compromising performance.

Designed with long-lasting durability in mind, the unit features a galvanized steel cabinet that protects internal components from physical damage, ensuring years of dependable operation. The cabinet’s baked-on, corrosion-resistant finish further shields it from rust, salt spray, and severe weather—ideal for homes in coastal or humid environments.

One of the standout features is its Vortica™ blower with an aerodynamic design that promotes high-volume airflow while consuming less power. This not only enhances comfort by keeping room temperatures more consistent but also contributes to overall energy savings. Powered by a high-efficiency multi-speed ECM motor, the blower can automatically adjust to your home’s needs—resulting in quieter operation and optimized efficiency throughout the seasons.

For added comfort control, this Trane air handler integrates Comfort-R™ humidity control, which slows blower speed during startup to remove more moisture from the air. This is especially beneficial in warm, humid climates where excess indoor humidity can lead to discomfort and potential mold growth.

The system's 4-way convertible configuration—upflow, downflow, horizontal left, and horizontal right—makes installation easier, even in tight or awkward spaces such as attics, closets, crawl spaces, or basements. This flexibility helps HVAC professionals save time and minimizes the need for structural changes during installation.

Engineered for both straight-cool and heat-pump systems, this air handler easily pairs with a variety of outdoor units, providing homeowners with precise, year-round temperature regulation. The optional electric heat kit offers dependable supplemental heating, ensuring you stay warm even during colder months.

Indoor air quality is a growing concern, and this model is fully compatible with Trane CleanEffects™, a cutting-edge air filtration system capable of removing up to 99.98% of airborne particles. This makes it an excellent choice for allergy sufferers or households concerned about indoor pollutants.

The all-aluminum coil resists corrosion and improves long-term heat transfer, reducing the likelihood of refrigerant leaks and enhancing system reliability. Additionally, a no-rust polymer drain pan prevents standing water and microbial buildup, protecting your home from potential water damage and maintenance issues.

With its compact dimensions (46-3/4" H x 18-1/2" W x 21-1/8" D) and thoughtfully engineered features, the Trane 5TEM4B03AC31S is a premium air handler that offers high performance, quiet operation, improved air quality, and year-round comfort—all at a price point around $1,700.
