From our humble beginnings in rural Coolidge Arizona (pop. 8,400) Harmony Security has grown into the nation's premier security provider. 

Although it was difficult to see our home town go, efficiency demanded we move to a more geographically central location. At Harmony Security, the decision to keep costs low and keep our customers happy is always the right choice.

After two decades, Harmony Security understands the Arizona market better than any other security company. Keeping up with changing times is what we do best. Like an oasis in the desert, you will find that dealing with Harmony Security is very refreshing.
