AJ Long Team Working

Make your home smarter and more connected with professional installation that ensures every device works reliably from day one. We bring multi-protocol expertise across WiFi, Zigbee, Z-Wave, and Lutron Clear Connect, so we can recommend the right technology for each application in your home. Our most popular service is smart switch and dimmer installation, where we assess your switch boxes for neutral wires and install compatible devices -- including Lutron Caseta systems that work even in older homes without neutral wires. We install and wire video doorbells from Ring, Nest, and other brands, including transformer upgrades and new low-voltage wiring when your existing doorbell infrastructure is inadequate. For security, we run Cat6 cabling and install Power over Ethernet (PoE) camera systems that are far more reliable than WiFi cameras. Smart thermostat installations include C-wire additions for Nest, Ecobee, and other brands that require the common wire your older HVAC system may lack.

Local Expertise

Northern Virginia Service Context

Serving the DMV Region

Fairfax, Arlington, Alexandria, Loudoun & Prince William Counties

Northern Virginia's smart home market is among the most sophisticated in the country, driven by the region's technology-savvy population and high concentration of IT professionals who understand and demand reliable home automation. The NoVA housing stock presents unique challenges: colonials from the 1970s-1990s in McLean and Vienna typically lack neutral wires in switch boxes, while newer construction in Ashburn and Brambleton may have builder-grade smart features that homeowners want to upgrade to professional systems. Dominion Energy's time-of-use rate plans make smart thermostats and automated energy management particularly valuable, allowing homeowners to shift HVAC and heavy loads to off-peak hours. The region's four-season climate demands systems that work reliably through humid summers and freezing winters -- battery-powered devices like Ring doorbells lose significant battery life in cold weather, making hardwired alternatives essential. Northern Virginia's security-conscious culture, influenced by proximity to federal agencies and defense contractors, drives strong demand for professional PoE camera systems over consumer WiFi alternatives. The competitive real estate market also motivates smart home investment, as homes with integrated smart lighting, security, and climate control command premiums of $10,000-$25,000 in the Fairfax and Loudoun County markets.

Smart Home Case Studies

See how we have helped homeowners across Northern Virginia with their smart home needs.

Whole-Home Lutron Caseta System in Vienna Colonial

colonial
Vienna, VA, Fairfax

Challenge

A 1985 colonial in Vienna had no neutral wires in any switch boxes, making most smart switches incompatible. The homeowners wanted whole-home smart lighting control with Alexa integration across 32 switches and dimmers on two floors.

Solution

We installed a complete Lutron Caseta system with a Smart Bridge Pro, replacing all 32 switches and dimmers with Caseta devices that operate without neutral wires. Pico remotes were added as 3-way companions and bedside controllers, and the entire system was integrated with the family's Alexa ecosystem.

Result

The homeowners control every light via voice, app, or Pico remotes. Automated schedules turn lights on at sunset and off at bedtime, and the family reports a 20% reduction in lighting energy use from the automated scenes.

PoE Camera and Ring Doorbell System in Reston Townhome

townhome
Reston, VA, Fairfax

Challenge

A Reston townhome owner was frustrated with unreliable WiFi cameras that dropped offline during critical moments. Their existing Ring doorbell ran on battery and needed constant recharging, especially during cold Northern Virginia winters when battery life dropped significantly.

Solution

We installed a 6-camera PoE system with Cat6 cabling run through the attic and walls to eliminate WiFi dependency. The Ring Video Doorbell was replaced with a wired Ring Video Doorbell Pro 2 with a new 24V transformer upgrade, and we ran dedicated low-voltage wiring from the transformer to the front door.

Result

All cameras now operate with 100% uptime on dedicated PoE connections. The wired Ring doorbell no longer needs battery charging and captures every visitor reliably, even during Northern Virginia's coldest months.

Control4 Smart Home Integration in Centreville Split-Level

split-level
Centreville, VA, Prince William

Challenge

A homeowner had accumulated a mix of smart devices across multiple ecosystems -- Nest thermostats, Hue bulbs, Ring cameras, and Kwikset locks -- that didn't communicate with each other. Managing four separate apps was frustrating, and automations between systems were unreliable.

Solution

We installed a Control4 EA-3 controller as a central hub, professionally wired Cat6 to key locations, and integrated all existing devices into a unified Control4 interface. Custom automations were programmed including an 'Away' mode that arms security, adjusts climate, and activates lighting schedules with a single tap.

Result

The homeowner controls their entire smart home from one app and a set of Control4 keypads. The unified system eliminated the compatibility headaches, and the professionally wired backbone ensures reliable communication between all devices.

Smart Lighting and Security for Great Falls Estate

estate
Great Falls, VA, Loudoun

Challenge

A 7,000-square-foot estate on 2 acres needed comprehensive smart lighting for both interior and extensive landscape lighting, plus a wired security camera system covering the property perimeter. The home's size exceeded the range of standard smart home wireless protocols.

Solution

We deployed a Lutron RadioRA 3 system with repeaters strategically placed to cover the entire home and outbuildings. A 16-camera PoE security system was installed with Cat6 cabling run to weatherproof cameras at all entry points and property boundaries. An equipment rack in the basement houses the NVR, network switch, and Lutron processor.

Result

The estate has seamless smart lighting control throughout, with landscape lighting scenes that transform the property at dusk. The camera system provides complete perimeter coverage with 30 days of continuous recording and remote viewing from anywhere.

By Home Type

Smart Home by Housing Type

Different home styles have unique electrical characteristics. Select your housing type to see specific considerations.

Colonial Homes

Common Issues

Switch boxes in 1970s-1990s colonials frequently lack neutral wires, limiting smart switch compatibility
Plaster or lathe walls in older colonials make fishing new wiring for cameras and sensors extremely difficult
Doorbell transformers are often undersized 10VA units that cannot power modern video doorbells requiring 16-24VA

Special Considerations

Colonial homes in McLean, Vienna, and Oakton are among our most frequent smart home projects. We recommend Lutron Caseta for these homes because it works without neutral wires and uses reliable radio frequency communication that penetrates the thick walls common in colonials. For camera installations, we route Cat6 through attic spaces and interior wall cavities to avoid exterior conduit runs.

FAQs

Frequently Asked Questions

Get answers to common questions about our smart home services.

Do smart switches require a neutral wire?

Most smart switches require a neutral wire to power their electronics. Many older homes have switch boxes without neutral wires, which limits your options. Some brands like Lutron Caseta work without a neutral. We assess your switch boxes and recommend compatible products for your home's wiring.

Can I install a video doorbell if I don't have doorbell wiring?

Yes, there are options. Some video doorbells are battery-powered and don't require wiring at all. Alternatively, we can run new low-voltage doorbell wiring from your transformer to the door location. Hardwired doorbells offer more reliable operation without battery charging.

What is the difference between WiFi smart devices and systems like Lutron Caseta?

WiFi devices connect directly to your router and are simple to set up but can bog down networks with many devices. Systems like Lutron Caseta use dedicated wireless frequencies with a central hub, offering more reliable operation and better dimming performance. We recommend Caseta for lighting control.

Will my smart home devices work if the internet goes out?

Most smart switches still function manually and through their local hub during internet outages, but you lose remote app control and voice commands. Some devices like WiFi-only bulbs may not work at all without internet. Hub-based systems like Lutron generally offer better offline functionality.

Can you install hardwired security cameras?

Yes, we install Power over Ethernet (PoE) camera systems where a single cable provides both power and data to each camera. This is more reliable than WiFi cameras and doesn't add traffic to your wireless network. We run cabling and set up the recording system.

Do I need an electrician to install a smart thermostat?

Many smart thermostats can be DIY installed, but we recommend professional installation if you have an older HVAC system, don't have a C-wire (common wire), or aren't comfortable identifying thermostat wiring. We ensure compatibility and add the C-wire if needed.

Can smart switches work with LED lights?

Yes, but compatibility matters. Some LED bulbs flicker or don't dim smoothly with certain smart dimmers. We recommend compatible LED bulbs or integrated smart LED fixtures. Lutron Caseta dimmers are known for excellent LED compatibility and smooth dimming.

Can I mix different smart home brands and ecosystems?

Yes, but with planning. Devices on different protocols (WiFi, Zigbee, Z-Wave) can coexist using a hub like SmartThings or through voice assistants like Alexa that bridge multiple ecosystems. We recommend sticking with one protocol per category for reliability -- for example, Lutron for all lighting and Ring for all security.

What is the Matter protocol and should I wait for it?

Matter is a new universal smart home standard backed by Apple, Google, Amazon, and Samsung that allows devices from different brands to work together natively. Many new devices already support Matter. We install Matter-compatible devices and can future-proof your wiring. You do not need to wait -- current smart devices work well today.

How many smart devices can my home WiFi network handle?

Most home routers handle 20-30 WiFi devices before performance degrades. Each smart plug, bulb, or switch counts as a device. This is why we often recommend hub-based systems like Lutron Caseta or Zigbee devices that use their own radio frequency and do not burden your WiFi network.

Do smart locks require an electrician to install?

Most smart locks replace standard deadbolts and are battery-powered, making them a straightforward DIY project. However, if you want a hardwired smart lock, need to integrate it with a smart home system, or want to add a doorbell camera at the same time, we can handle the complete installation and integration.

Can smart home upgrades qualify for insurance discounts?

Some insurance providers offer discounts for homes with professionally installed smart security systems, water leak sensors, and monitored smoke detectors. Smart doorbells and cameras that provide recorded evidence can also help with claims. Check with your insurer about available smart home discounts in Virginia.
