Luk had completed the tune up, but uncounted an error code at the last minute. He persisted in resolving the code problem with the assistance of Brian over the phone. Luk's technical knowledge, combined with Brian's extensive experience, resulted in the resolution of the error code issue. Their insistence on working out the problem, and not leaving it unresolved resulted in 100% satisfaction on our end. We thank them for their time, patience and dedication to their craft, and appreciate the comfort and peace of mind Central Cooling brings to us in our home.
