Residents of Manhattan, Brooklyn, or Queens apartments would all agree how their Intercom systems are indispensable.

It’s not just a way to manage visitors, it enables them to identify package thieves, weed out door-to-door advertisers, and other unwanted guests. Some municipalities, like New York City, even require them by law. We work hand and hand with Home Owner Associations, Property Owners, and Property Managers helping them identify the best solution to setup for the situation.

Video intercoms, audio only systems, internet based systems, or dialer intercoms, we have your solution.

Areas of Service:

Repair & Maintenance (Intercom Troubleshooting)

At EZ Switch, we’re just as efficient keeping your pre-existing system up and running as we are installing a new one. Our refurbishing facilities allow us to repair some of the most common causes of system failure. (providing parts are still available and sometimes even longer.) Our technicians are familiar with a broad list of systems from dozens of manufacturers including but not limited to:

Tek-Tone, Lee Dan, Alpha Communications, DOORKING, Comelit, AiPhone, many more.


Some solutions require programming, some pliers, and others a soldering iron, either way we’re always prepared.

New Intercom Installation for Multi-Tenant Buildings

You could be looking at blueprints for new construction or renovating an existing structure, we can help you find the right solution for the job. Because we are familiar with all the brands on the market, we have a solution for almost any situation.

Most Requested Upgrades

When property owners and managers upgrade a Building Intercom System, they’re often not starting from scratch—they’re improving what’s already there through a Building Intercom System retrofit. These are the most requested Building Intercom System upgrades we’re asked to design and install in residential multi-tenant buildings.


A video Building Intercom System with mobile app is one of the most common upgrades because it adds visual verification and lets residents answer visitors from their phone whether they’re home or not. For buildings that want smoother everyday entry, key fob / card + Building Intercom System integration combines credential-based access with intercom calling, so tenants and approved users can enter quickly while visitors can still request access through the panel. We also regularly modernize the Building Intercom System tenant directory, replacing outdated or hard-to-use directories with a cleaner, easier experience for guests, deliveries, and service providers.


If your current Building Intercom System supports it—or if you’re upgrading to a platform that does—we can also review visitor and delivery management options that fit how your building operates. (Availability depends on the specific system and configuration.)

Intercom Retrofits (Reuse Existing Wiring When Possible)

Is the life of your system up? Need to upgrade and not sure which system to use? We’ll help you select the system right for you. We have numerous options available that can help minimize your costs and provide great new features. Transform your existing doorbell or intercom system into a video intercom. Residents can answer the door whether they’re home or not with our phone app.

Video Intercom + Mobile Entry Options

Your solution to dysfunctional wiring or when wiring isn’t an option. These systems work entirely over the internet managed in the cloud with audio and video options available even in buildings where the existing wiring is no longer serviceable.


What? There’s no internet available? No Problem! We can add a cellular module to the system resolving this issue.

Please check with your local building department to determine if individual tenant stations are required by local code. That being the case, we can help using each apartment’s internet connection and install individual tenant stations.

What to Expect in a Building Intercom System Site Walk

A Building Intercom System site walk is an on-site walkthrough where we evaluate your building’s entry setup and existing infrastructure so we can recommend the best repair, retrofit, or new installation options—based on how your property actually operates.


During your Building Intercom System site walk, we typically cover:



  • Entry points reviewed: where visitors arrive and how access is currently handled
  • Existing wiring assessed: whether current wiring is serviceable or limiting upgrade options
  • Tenant count + directory needs: how many units, how the directory should function, and what’s easiest for visitors to use
  • Recommendations + options within budget: practical paths forward aligned with your building and budget goals

Telephone Dialers: When They Still Make Sense

A tried and true approach or what may be considered as “Old Reliable” for buildings that don’t have functional wires to every apartment, or large residential developments, is a telephone dialer system.

Each tenant is assigned a code so when a visitor punches that code into the panel’s keypad, the panel dials the phone number connected to that tenant. The tenant answers, presses “9” on their phone and the door or gate opens.

With this system, there’s one pre-programmed phone number per code. Wait! My residence is cellular only. No dedicated phone line? No problem. A cellular option is available when a dedicated phone line isn’t.

Cutting Edge Systems

Intercoms have come a long way from the days of “push-to-talk” and privacy handsets. Today, systems integrate card readers and postal key modules, making for a cleaner appearance in the lobby. There are also visitor management options, so that tenants and building managers can grant temporary access to visitors and guests. Once the guest’s details are entered into the system’s online “portal,” an invitation email is sent to the visitor. This email features a “QR code“, which will be scanned by the intercom’s camera for building access. The code acts like an access card for the guest and is only active during scheduled hours. Access expires based on the manager’s instructions.


Working together with the building managers, we will help you set up an access schedule that’s appropriate for which the tenants can grant guest credentials. At all other times, visitors will need to be buzzed in. It is an intercom and access control solution in one tidy package.

Other Systems

Are you looking for a more economical option? Our phone dialer systems are the ideal option. Visitors call your unique number, enter a code, and they generally don’t require additional wiring. (They work with any wired or cell number).

Typically this can require an additional phone line, but an optional cellular module is available.

Building Intercom System FAQs

  • How do I know if my building should repair or replace the intercom?

    If your Building Intercom System has a specific failure (like a bad component, handset, or panel issue), a repair or targeted refurbishment may be the right first step—especially when parts are still available. If failures are frequent, the system is at end-of-life, or the building needs modern features like video or mobile answering, a Building Intercom System upgrade or replacement is often the smarter long-term move. A site walk helps confirm whether the existing infrastructure supports a reliable repair or whether replacement makes more sense.

  • Can you retrofit a system using existing wiring?

    In many cases, yes—an intercom retrofit can reuse existing wiring if it’s still serviceable and compatible with the upgrade path. When wiring is degraded or incomplete, we may recommend an alternative approach such as an internet-based Building Intercom System. The best option depends on what wiring exists today, the entry configuration, and what features you want to add.

  • Do you service NYC boroughs + Long Island?

    We specifically reference working with residential multi-tenant buildings in Manhattan, Brooklyn, and Queens. If you’re located in another borough or on Long Island, the best next step is to contact us so we can confirm coverage for your property and the type of Building Intercom System work you need. That quick check ensures you get accurate scheduling and recommendations from the start.

  • What affects the cost of a building intercom project?

    The cost of a Building Intercom System project depends on the building’s entry points, the number of tenants, directory requirements, and whether the existing wiring can be reused. System type also matters—audio-only, video intercom, internet-based, or telephone dialer configurations each have different equipment and setup needs. Programming requirements, installation complexity, and any desired access integrations can also influence overall scope.

  • How long does a typical install/upgrade take?

    A Building Intercom System install or upgrade timeline varies based on the number of doors, tenant count, wiring condition, and whether programming or directory changes are needed. Retrofits can sometimes move faster when infrastructure is usable, while projects involving wiring limitations or system conversions may take longer. A site walk is the fastest way to estimate timing accurately for your specific building.
