Our promise on every order
- Typically ships in 3–7 business days — crated and moved by LTL freight from Southwest Florida. The carrier then schedules delivery with you.
- Manufacturer specifications, published — model number, capacity, efficiency and refrigerant are all listed below, so you can check this against what your contractor specified.
- Check your match in seconds — put in the two model numbers you were quoted and see whether that pair is AHRI-certified before you spend anything. Not sure, or not our equipment? Send them to us and we will look them up by hand.
- 30 days to return unopened equipment — full returns policy.
What's included, and what your installer supplies Ships as one crate by freight. Installation is not included.
In the box: the indoor air handler only. It needs a matched outdoor unit: check the AHRI match.
Your installer supplies the line set (or reuses yours if it qualifies: reuse or replace?), power wiring and disconnect, thermostat and control wire, condensate drain and float switch, and the permit.
Electric heat is not included. If you want it, add the matching Trane / RunTru heat kit.
Installation is by your licensed HVAC contractor. How to find one.
About this unit
Trane's workhorse indoor half
The 5TEM4 is the air handler most Trane split systems in this catalog are built around. It is the convertible, multi-position cabinet that pairs with the 5TTR and 5TWR condensers, and it is the match behind most of the certified ratings you will see on our complete systems. If you are buying a Trane condenser and have no specific reason to choose otherwise, this is the handler that goes with it.
What the ECM blower changes
An ECM blower is an electronically commutated motor, and the practical difference is that it can run at part speed instead of only full speed. Two consequences you will notice: it draws substantially fewer watts across a season than an old PSC motor, because fan power falls faster than fan speed does; and it can hold a long, low airflow that strips humidity out of the house instead of short-cycling. In a climate where the discomfort is moisture rather than heat, that second point is the one that matters.
Convertible, so the building decides
Upflow, downflow and horizontal from one cabinet, configured at installation. An attic install goes horizontal, a closet goes upflow, and neither requires a different part number. The cabinet is insulated and factory-sealed, which keeps conditioned air inside the box rather than losing it into an unconditioned attic before it reaches a register.
It sets your efficiency, not the condenser
SEER2 is a property of the certified pair. The same 5TTR6 condenser certifies at different numbers depending on which indoor unit is behind it — around 15.2 SEER2 with this handler, and higher with the Hyperion 5TAM5. Neither is wrong; they are different systems. Read the AHRI reference number for the exact combination rather than the headline figure on any one component.
Heat kit sold separately
On a heat pump, or for auxiliary heat on a cooling-only system, the electric heat kit installs in this cabinet and is sized in kilowatts. It is listed in our accessories and is the item most often left off an order. Your installer should specify the rating for your house and climate.

Key features
- Efficient ECM blower (variable/multi-speed capable)
- Convertible, multi-position installation
- Improved humidity control & quiet operation
- Durable insulated cabinet, R-454B compatible
- Designed to match Trane 5TTR / 5TWR outdoor units
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.
- Published warranty terms. Trane's own limited warranty offers longer parts coverage when registered within 60 days, under Trane's conditions. Read them at trane.com before you buy.

Shipping & returns
- $349 delivered to your door, liftgate included — $499 to AZ, CA, CO, ID, MT, NM, NV, OR, UT, WA and WY. One flat price whatever it weighs, with nothing added at checkout. Ships to the 48 contiguous states and DC.
- Must be installed by a licensed HVAC professional — opening refrigerant lines requires EPA certification.
- 30-day returns on unopened equipment, 20% restocking fee. No returns on installed units.
How buying the equipment yourself works — the whole process, start to finish
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. Line set, disconnect, whip, thermostat and equipment pad are not included — your installer supplies those. If the manufacturer's terms allow, register the equipment. Trane and RunTru offer longer parts coverage when registered within 60 days, subject to their conditions. Check the manufacturer's terms before you buy. Warranty terms.
