To go the extra mile for your professionally installed ecobee, we offer a 5-year pro warranty—which is an extra 2 years in addition to the 3-year standard retail warranty.
During the warranty period, we will repair or replace any defective ecobee thermostats free of charge. However, replacements do not include installation. Replacements or repaired devices will be protected by the remainder of the warranty period or 90 days (whichever is longer). All you need is a proof-of-purchase.
Please note that this warranty applies only to ecobee3 lite pro. It is only valid in cases of professional installation and in the country of purchase.
