HVAC Service Call




Jermaine had a very pleasant demeanor and provided me with requested advice on how a problem unrelated to his service call might be solved. The service call appeared to be handled well. I have not rated the quality of Jermaine's work only because I do not consider myself sufficiently knowledgeable about the what's required in serving a wine cellar air conditioner to make a judgement on this point.

A neat freak with a dirty AC unit!




I have a Sanyo unit that needed cleaning and it is located in a cream colored room with cream carpet and furniture. Jeremy, the HVAC tech, was on time, courteous and neat. I am very happy with the service and will continue to use HVAC for all of my AC needs.
