Trane TMM Series air handlers
The most budget-friendly air handler from Trane is the TMM Series. This series currently has two models, the TMM4 and TMM5. The TMM5 sizes up to a 3-ton unit, so this series is designed for small to medium-sized spaces.
The TMM Series is the only option to be mounted on studs or over the hot water heater for smaller spaces. Despite the entry-level pricing of this series, both models are designed with all-aluminum coils for extended durability.

The TMM4 and TMM5 models are best for people in smaller spaces. If you don’t have an attic or a basement, this line of air handlers fits well above your water heater or in a closet.
The single-speed motor in this line is less energy-efficient than other Trane air handler models, but if sized properly for your space, the unit will distribute air evenly.
Also, this series has a smaller capacity limit than most other Trane air handlers. If your air conditioner has a capacity over 36,000 btu/hour or is built for zoning, you’ll need a bigger and more sophisticated model for the job.
Still, this affordable and simple series is great for smaller homes. We recommend it over competing wall mounts like the Goodman AWUF/AWUT series.
