In this comprehensive guide, we will unravel the mystery behind Lennox HVAC model numbers for various product categories, providing you with the knowledge you need to make informed decisions about your HVAC system.

Deciphering Lennox HVAC Model Numbers

Lennox HVAC model numbers are alphanumeric codes that consist of letters and numbers. Each component of the model number represents specific information about the product. Here’s how to decode a typical Lennox HVAC model number:

Let’s take the example model number “XC25-036-230-03” and break it down:

1. Product Series (XC25): The first part of the model number signifies the product series or category. In this case, “XC25” represents a premium air conditioner.
2. Capacity (036): This segment indicates the cooling capacity of the unit in BTUs (British Thermal Units) per hour. In this example, the unit has a cooling capacity of 36,000 BTU/hr.
3. Voltage (230): The third part denotes the voltage requirements for the unit. In this case, “230” signifies that the unit operates on 230 volts.
4. Product Version (03): The final digits indicate the product version or series within the model category. Different versions may have variations in features or efficiency levels.
