  • Is Lennox better than carrier?

For mid-level and basic air conditioners, then Carrier and Trane have better warranties than Lennox. In part, Lennox reduces the warranty to lower its risk, so that it can offer lower prices on base models. However, slightly lower quality accounts for some of the rationale for a 5-year parts warranty.
