What Is Lennox Nomenclature?
Lennox nomenclature refers to the structured alphanumeric system used by Lennox to name and categorize their HVAC equipment. This coding system encodes vital information about each unit—including its size, type, efficiency, and features—within a compact alphanumeric string.
Understanding this nomenclature is crucial for:
- Selecting the right HVAC unit for a specific application
- Ensuring compatibility with existing systems
- Facilitating maintenance and repairs
- Making informed purchasing decisions
Lennox’s coding system is designed to be logical and consistent, allowing both professionals and consumers to decode product specifications with relative ease once familiar with the format.

Structure of Lennox Nomenclature
Lennox model codes typically consist of multiple parts, each representing different attributes of the HVAC unit. Though variations exist across different product lines, most Lennox models follow a similar structure.
A typical Lennox model code might look like this:
ML14XC1-060-01
Breaking down this code:
- ML14XC1: Model series and configuration
- 060: Capacity or size
- 01: Sub-model or specific features
Let’s dive into each component to understand what they signify.

Deciphering the Components of Lennox Nomenclature
1. Model Series and Configuration
This initial part of the code usually indicates the model series or family and sometimes the configuration.
- Letters and numbers: Denote the series, efficiency level, and specific features.
Examples:
- ML: Modulating gas furnace series
- XC: Air conditioner series
- XP: Heat pump series
Key points:
- The series letter often indicates the product type (e.g., furnace, air conditioner, heat pump).
- The subsequent characters specify the model’s features, such as efficiency ratings or design modifications.

2. Capacity or Size Indicators
Lennox uses numerical codes—often three digits—to specify the capacity of the unit.
Examples:
- 060: 60,000 BTU/hr or 5 Tons
- 090: 90,000 BTU/hr or 7.5 Tons
Understanding capacity codes:
- The number typically corresponds to the unit's cooling or heating output in thousands of BTUs per hour.
- For example, "060" equals 60,000 BTUs, commonly associated with 2-ton systems, as 12,000 BTUs equal 1 ton.

3. Sub-models and Feature Codes
The last part of the code often indicates specific features or sub-model details.
Examples:
- 01: Standard features
- 02: Enhanced features or configurations
Sometimes, these are used to denote variations like different control options, coil configurations, or other options.

Common Lennox Nomenclature Patterns
Different Lennox product lines have their own specific naming conventions. Here are some examples:
Lennox Air Conditioners and Heat Pumps
Model code structure:
Series + Capacity + Optional Features
Example:
XC21-060-01
- XC21: High-efficiency air conditioner
- 060: 60,000 BTU/hr capacity
- 01: Standard configuration
Lennox Furnaces
Model code structure:
Series + AFUE efficiency rating + Size
Example:
ML14XC1-060-01
- ML14XC1: Model series, often indicating modulating furnace with specific features
- 060: 60,000 BTU/hr capacity
- 01: Standard configuration
Lennox Packaged Units
Model code might include:
P + Series + Capacity + Features
Example:
PCA4-060-01
- P: Packaged unit
- CA4: Model series
- 060: Capacity
- 01: Features

To better understand Lennox nomenclature, let's analyze some real-world examples:
Example 1: Lennox XC25-060-01
- XC25: A high-efficiency central air conditioner with variable-speed technology.
- 060: 60,000 BTU/hr, suitable for a 5-ton cooling capacity.
- 01: Standard or base model features.
Example 2: Lennox ML14XC1-090-02
- ML14XC1: A modulating furnace series with specific features.
- 090: 90,000 BTU/hr, typically matching a 7.5-ton heating capacity.
- 02: An upgraded or alternative configuration with additional features.
Example 3: Lennox PCA4-060-01
- P: Packaged unit designed for commercial or residential rooftop applications.
- CA4: Specific model series indicating features like efficiency or design.
- 060: 60,000 BTU/hr capacity.
- 01: Standard features.
