As of 2015, Gibson heating and cooling systems come with 10-year limited warranties on all parts and lifetime warranties on the heat exchanger after registration. Without registration, each system comes with a five-year all-parts warranty and a 20-year heat exchanger warranty.
In addition to the standard protection, Gibson provides a one-year quality pledge. Original owners who register their products can get any failing units replaced during the first year after installation. The pledge applies to all models except JT4BD and JT4BE heat pumps, and JS4BD, JS4BE and JS6BD air conditioners. These HVAC warranties apply to parts and systems manufactured after Jan. 1, 2015.
