The most common themes include frequent premature failures of key system components, long wait times for replacement parts, and dissatisfaction with warranty coverage and claims handling. Customers in locations like Texas and South Florida underscore the urgency of fast air conditioning repairs, given extreme weather. Several reviews express disappointment that labor and some parts are not fully covered, and criticize the communication between Lennox, its dealers, and end customers.
Overall, Lennox’s reputation, especially in the U.S., is negatively affected by these recurring product and service issues, with many customers stating they would not recommend, or would actively avoid, the brand in the future. Consistent patterns of unresolved warranty problems and poor post-sale support undermine trust among buyers.
