Coleman Model Number Lookup: How to Read Coleman Furnace and AC Model Numbers

Coleman model numbers pack the tier, staging, efficiency, capacity and cabinet size of the unit into one string. Once you know where to split it, a Coleman model number tells you almost everything except the unit's age. This guide decodes Coleman furnace and air-conditioner model numbers position by position, using the key the manufacturer prints on its product data sheets.

Coleman is built by Johnson Controls (shared platform with York and Luxaire). Coleman residential furnaces share the Johnson Controls platform with York and Luxaire. A Coleman TM9V is the sibling of a York TM9V / Luxaire TM9V, so the position table below applies across those badges. Outdoor units often start with a C instead of York's Y.

Furnace positions match Johnson Controls product data for TM9/TG9-class units (shared with York/Luxaire; confirmed against TM9E model lists). Outdoor lettering is typical Coleman decoding guidance.

Where to Find the Coleman Model Number

On a furnace, the rating plate is inside the front door or on the side of the cabinet, usually a foil or paper label with the model (M/N) and serial (S/N) side by side. On an outdoor AC or heat pump it is on the side of the condenser near the refrigerant line connections. Copy the model number exactly as printed, including dashes: the position of each character is what carries the meaning.

A typical Coleman model number in this family looks like: TM9V080B12MP12C. Use the table to split it up:

Common Coleman Families

The first few characters identify the family, and the family tells you the tier, staging and blower (or inverter class) before you read a single digit of capacity.

Coleman AC and Heat Pump Model Numbers

Outdoor units use a different string. A typical Coleman outdoor model number looks like: CCG36B21S.

Coleman Tonnage by Model Number

Every Coleman outdoor unit carries its cooling capacity as a two- or three-digit BTU code. Divide by 12 to get tons (1 ton = 12,000 BTU/h). Furnace numbers carry the gas input instead, so a heating "080" means 80,000 BTU/h of heating, not 80,000 BTU/h of cooling.

What the Coleman Model Number Does Not Tell You

The model number says nothing about the unit's age. That is in the serial number, and Coleman (like most brands) has changed serial date formats over the years. Use the Coleman serial number lookup to turn a serial into a manufacture date, or the HVAC serial number decoder hub for any other brand. The model number also does not tell you whether the unit was installed and charged correctly, which matters as much as the SEER digit for what it actually costs to run.

Decoded Your Coleman? Here Is What to Do With It

If the unit is under 10 years old and the model number shows a mid- or high-efficiency family, it is usually worth repairing. If the serial dates it past 12 to 15 years for an AC or 15 to 20 years for a furnace, the capacity and cabinet width you just decoded are exactly what you need to size a replacement. A new system at the same tonnage and input will drop straight into the same duct and gas connections.
