Overview

About this unit

For the room that has no floor to give up

The 5TMM5 Compact Plus hangs on a wall. That is the entire reason it exists, and for the right installation nothing else will do. A converted garage, a bonus room over the garage, a sunroom, a mother-in-law addition, an office built into a corner of a workshop — spaces where a conventional upflow cabinet would consume floor area you added the room to gain. It mounts on the wall, leaves the floor clear, and takes standard ducted supply and return rather than the wall-blown air of a mini-split head.

1.5 to 3 ton, and that is a hard ceiling

This handler tops out at 3 tons. If your load calculation comes back above that, the 5TEM4 or the Hyperion 5TAM5 is the answer instead — do not try to stretch this one. An undersized handler behind an oversized condenser does not simply perform a little worse; it restricts airflow, drops coil temperature and starts freezing, and the compressor pays for it. Size the load first, then pick the cabinet.

Check your line routing before ordering

B0B models bring the refrigerant connections out at the top back of the cabinet. On a wall-mounted unit that is not a detail you can improvise around after delivery — the wall, the studs and the existing line set all have opinions. Have whoever is installing it confirm the connection location against the space before you order, because a wall handler with its connections on the wrong face is a return rather than an adjustment.

It takes a different heat strip

This unit uses the BAYHTRA5-BRK heat strip, not the standard BAYHTR kit that fits the 5TEM4 and the Hyperion. The two are not interchangeable. If you are ordering supplemental heat with a wall-mount handler, order the bracket-specific strip, and check it against the spec sheet on this page rather than against a heat kit listing written for a floor-standing cabinet.

Matching it correctly

Pairs with Trane 5TTR and 5TWR condensers on R-454B. As with every split system, the certified efficiency belongs to the pair rather than to either half, so read the AHRI reference number for the exact combination you intend to install — it is published on the complete-system listings.

The brand

Why Trane?

See everything we carry from Trane

The air handler is the half of the system that lives inside your house and runs every time the system does. Trane builds it to the same standard as the unit outside.

The blower decides how the house actually feels. A multi-speed or variable-speed blower runs longer at lower output instead of blasting and shutting off — and long, low airflow is what pulls humidity out of the air. A single-speed blower satisfies the thermostat quickly and leaves the room cold and clammy.
Built to sit in an attic for twenty years. Insulated, sealed cabinet. That is what stops an indoor coil sweating onto a ceiling below it, and what stops you paying to cool the attic instead of the house.
Convertible, multi-position. The 5TEM4 and the Hyperion 5TAM5 install upright or horizontal, so one part number fits a closet, an attic or a garage. Where none of them fit, the 5TMM5 mounts flat to a wall.
Takes a field-installed heat kit. Electric strips drop in behind a single polarized plug, covering a heat pump's backup heat or, on an air-conditioner system, the only heat in the house.
Warranty that rewards registering. Five years on parts as standard, extending to ten on most components when you register within 60 days at trane.com. Registration takes about four minutes and doubles your coverage.

How buying direct works — the whole process, start to finish 6 steps

You are buying the equipment from us and the labour from an installer you choose. Two numbers instead of one bundled quote — which is the point, but it does mean you are the one connecting them. Here is the whole sequence.

Order the equipment. The price on this page is what you pay us. Nothing about installation is included in it, and nothing is added later.
Line up your installer before it ships. This is the step people skip, and it is the one that causes trouble — equipment sitting in a garage while you ring round for someone free. You need a licensed HVAC professional; opening a refrigerant circuit requires EPA certification. Ask specifically what they charge to install customer-supplied equipment. How to find one.
It ships crated on a freight truck. Orders typically ship within 3–7 business days. A complete system travels as two crates — condenser and air handler — which can arrive on different days. Delivery is to your address on a liftgate truck for one flat price, with nothing to choose at checkout. What delivery costs.
The carrier calls to book a delivery window. That appointment is when your equipment arrives — not the ship date. Answer the call; an unanswered one is the most common cause of a delay.
Inspect it before you sign. Two minutes at the tail of the truck decide whether a damage claim works. Note any damage on the delivery receipt specifically, not just "damaged", and photograph it before it comes off the truck. What to check.
Your installer fits it, then register the warranty. Line set, disconnect, whip, thermostat and equipment pad are not included — your installer supplies those. Registering within 60 days of installation takes about four minutes and extends parts coverage from five years to ten. Warranty terms.
