Need to Upgrade Your Old Doorbell to a New Video System?

Updated: May 20

This Alpharetta client contacted us because their six-month-old Ring Doorbell was not working. They had an old Nutone intercom system throughout their house. This is very common to find in late 80's early 90's homes in the Alpharetta area. None of them are ever working anymore however.

Why Did the New Video System Stop Working?


Through initial diagnostics, I found that the transformer was very old and may have been the main culprit that made the new Ring doorbell stop working. Some of the wiring was not quite up to the professional expectations I would have as a licensed electrician. Sometime back, the client had hired a handyman to rewire their old Nutone Intercom system to allow them to install a new Ring doorbell.

We removed the old Nutone system completely because of the bad wiring and the faulty transformer. Then we rewired the doorbell system in a way that you would expect to see and have in any modern home. Once we finished, we also installed a new lightbulb that had gone out in the high stairwell. It had been out for months because they didn’t have the proper ladder to reach and replace it. So we did it for them.


What to do with an old intercom system


If you live in an older home with an outdated or broken intercom system you can remove or upgrade it. Intercom systems come in several types:


  • Hardwired

  • Plug In

  • Battery Operated


It's easier to remove a plug in or battery operated intercom. Contact a licensed electrician to help you remove one that has been hardwired into your home. You may also need some drywall repair when it has been removed.
