Sam was not only highly professional and knowledgeable but also incredibly kind and personable.

5/5 - I greatly appreciated his approachable and compassionate attitude as well as his expertise while he worked through fixing both our indoor and outdoor units.

(Also, congrats to him and his fiance!)
