The Most Common Video Doorbell Problem
Why Your Video Doorbell Isn’t Working — And How We Fix It
The number one reason Ring, Nest, and other video doorbells fail to charge, go offline, or flicker is a low-voltage transformer that can’t meet the device’s power requirements. Here’s what that means and what NorTech does about it.
Standard Doorbell Transformers
Most homes have a transformer rated at 8–10 volts AC — enough for a simple doorbell chime, but far too low for a video doorbell that requires 16–24V to charge and operate reliably.
What Goes Wrong
A video doorbell on an undersized transformer will drain faster than it charges, go offline frequently, fail to record motion events, or produce a constantly buzzing chime. These are wiring problems, not device problems.
How We Fix It
NorTech electricians locate your existing doorbell transformer — typically in a utility closet, basement, or mounted near the electrical panel — and replace it with a properly rated unit for your specific device.
What We Install
We install 16V–24V, 30VA or higher transformers compatible with Ring Pro, Ring Wired, Nest Hello, Nest Doorbell (wired), Arlo Wired, and other hardwired video doorbells.
Before You Call
Doorbell & Smart Lock Checklist
- Check whether you have existing doorbell wiring at the front door — two thin wires (low-voltage) typically visible at the doorbell button location. If there are no wires, we’ll need to run new wiring. If there are wires but the doorbell doesn’t work, we’ll diagnose the transformer and chime.
- If your video doorbell is already installed but keeps going offline or won’t charge, locate your doorbell transformer — usually found in a utility closet, mechanical room, or near the electrical panel. Note the voltage printed on it. Anything below 16V will likely need to be replaced.
- For smart lock installation, confirm your door’s backset measurement (the distance from the door edge to the center of the existing lockset hole — typically 2-3/8″ or 2-3/4″). This determines lock compatibility before we arrive.
- If you want doorbell and smart lock installed together, have both devices unboxed and accessible. Combined installs in one visit save time and are the most cost-efficient approach.

What Affects the Cost of Doorbell & Smart Lock Installation?
Doorbell and smart lock installation is among the most straightforward electrical work — here’s what determines the scope and price of your job.
Every job starts with a full written estimate. You receive complete pricing before any work begins — no surprises.
“My Ring Pro kept going offline and wouldn’t hold a charge. NorTech found the transformer, confirmed it was only 8V, replaced it with a 24V unit, and the doorbell has been working flawlessly ever since. Problem solved in under an hour.”
Chris V.“Had a Nest Hello installed at the front door and a Yale smart lock on the side entry — all in one visit. The tech handled both perfectly and left everything clean. Great efficiency.”
Monique B.“No existing doorbell wiring at my condo unit. NorTech ran new low-voltage wire from the transformer and installed the Ring doorbell. Took longer than I expected due to the routing, but it’s done right and looks clean.”
Layla S.“Schlage Encode installed on the front door and garage entry. The tech made sure both doors latched properly before leaving — adjusted the strike plate on the front door. That attention to detail matters.”
Omar T.“My old chime was buzzing constantly after installing a Ring doorbell. NorTech installed a chime bypass kit and the buzzing stopped immediately. Should have called sooner — simple fix.”
Debra N.“Needed doorbell wiring added for a back door that never had one. The tech ran the wire neatly inside the wall and installed the video doorbell. You’d never know it wasn’t original to the house.”
Patrick G.Common Questions
Frequently Asked Questions — Doorbell & Smart Lock Installation
Why won’t my video doorbell stay charged or work properly?
Most video doorbells like Ring and Nest Hello require a transformer that outputs at least 16–24 volts AC to charge and operate correctly. Many older homes have low-output transformers (8–10V) that cannot power modern video doorbells. NorTech electricians can replace your existing transformer with a compatible unit, resolving charging and connectivity problems.
Can NorTech install a video doorbell where there is no existing doorbell wiring?
Yes. NorTech electricians can run new low-voltage doorbell wiring from a transformer to a new doorbell location. This is a common installation for newer homes, additions, or secondary entry points that were never wired for a doorbell.
What transformer does Ring or Nest Hello require?
Ring Video Doorbell Pro and Nest Hello typically require a transformer rated at 16–24 volts AC and at least 30VA. Standard Ring Video Doorbells can operate on 8–24V but perform best at the higher end. NorTech electricians verify your existing transformer rating and replace it if it does not meet the device requirements.
Do smart locks require electrical wiring?
Most smart deadbolts are battery-operated and do not require electrical wiring for the lock itself. However, some smart lock setups — particularly those integrated with access control systems, electric strikes, or door entry systems — do require wiring. NorTech handles smart deadbolt installation, strike plate alignment, and any associated low-voltage or line-voltage wiring.
Can NorTech install a doorbell and smart lock at the same time?
Yes. Combining doorbell and smart lock installation in one visit is the most efficient approach. NorTech electricians can handle both in a single service call — doorbell wiring and transformer work, plus smart lock mounting and any associated wiring.
How much does video doorbell installation cost?
Video doorbell installation cost depends on whether existing wiring is present and compatible, whether a transformer upgrade is needed, and whether a new chime or chime bypass is required. NorTech provides a written estimate before any work begins.
Can NorTech install a doorbell chime or replace an existing one?
Yes. NorTech installs and replaces wired doorbell chimes, and can install digital chime kits compatible with video doorbells. Some video doorbells require a chime bypass kit to prevent buzzing or damage to the chime — our electricians handle this as part of the installation.
What smart lock brands does NorTech install?
NorTech installs all major smart lock brands including Schlage Encode, Yale Assure, August Smart Lock, Kwikset Halo, and others. We install customer-supplied locks as well as locks we can source. Our role covers installation, strike plate adjustment, and any wiring — app setup and code programming are handled by the homeowner.
