Lennox Frequently Asked Questions

On average, Lennox air conditioners can last for 15 to 20 years. These sturdy and reliable AC units will remain operational for over a decade, typically without any significant repairs or replacements needed. 


However, the life span of a Lennox air conditioner is also affected by the amount of ongoing maintenance. 


Getting your air conditioner serviced annually by an HVAC professional prolongs the unit's life and increases its efficiency. 


Warranties on eligible products from Lennox Industries depend on the product model. Parts-only coverage ranges from three to 10 years. You can get coverage on heat pumps and their components for up to 20 years with an extended warranty — or even for life in certain models that use oil. 


When changing air filters the standard, one-inch disposable air filters should be changed every three months.
