Stay away - this is the first negative review that I have ever left a business but it is well deserved (and I have been a customer for over 6 years so trust me, I know)....the customer service is awful and it appears that they do not care about the residential side of their business.
Have waited for close to a year for a security upgrade and there is no follow-up from Johnny or his manager.
Honest advice is take your business to a more reputable alarm company.
