Types of Lennox air conditioners

With several types of Lennox air conditioners on the market, the possibilities can be overwhelming. That’s why it’s important to familiarize yourself with the options.

Lennox offers central air conditioners, mini-split air conditioners, window air conditioners, portable air conditioners, and packaged air conditioners to suit different needs and space requirements.

Lennox air conditioner models

Consumers can choose from several Lennox air conditioner models that come in up to five-ton units. The SEER rating is the ratio of an AC unit’s cooling output over a standard cooling season against the total energy consumed over the same time.
