Marvin's Heating & AC Service is a comprehensive, experienced, competitively priced service. I have used his service for many years. Even when I moved to Maryland, I've continued to use his service. Marvin was available to check and repair a malfunction of the furnace that occurred this past fall. He is a very reliable, courteous, and efficient contractor. In particular, he is able to advise on long-term maintenance checks, preventive measures to sustain units. He respond to calls when acute problems occur and is commited to completing the work in a timely fashion. I highly recommend this company and the services provided by Marvin Hopkins.
