Generator Installation and Sizing Guide for Northern Virginia

When severe weather strikes Northern Virginia, power outages can leave homes from Fairfax to Alexandria and Arlington without electricity for hours or even days. Summer storms, winter ice, and increasingly unpredictable weather patterns have made whole house generators more than just a luxury—they're an essential investment in your home's resilience and your family's safety.

Whether you're protecting medical equipment, maintaining a home office in McLean, safeguarding frozen food supplies, or simply ensuring comfort during extended outages in Ashburn, a properly sized and installed whole house generator provides peace of mind when the grid goes down.

At AJ Long Electric, we've installed hundreds of backup power systems throughout Northern Virginia. This comprehensive guide will walk you through everything you need to know about sizing, selecting, and installing a whole house generator that meets your specific needs, budget, and local code requirements.

Why Northern Virginia Homeowners Need Whole House Generators

Power reliability in Northern Virginia has become increasingly unpredictable. Between Dominion Energy's aging infrastructure in certain areas and the region's susceptibility to severe weather, homeowners face multiple outage risks throughout the year.

Key reasons Northern Virginia residents invest in generators:

• Storm Preparedness: Summer thunderstorms, winter ice storms, and occasional hurricanes regularly knock out power across the region. Derecho-like events can leave areas without power for a week or more.
• Medical Equipment Protection: For families with CPAP machines, oxygen concentrators, medication refrigeration, or other critical medical devices, backup power isn't optional—it's essential.
• Home Office Continuity: With many Northern Virginia professionals working remotely, maintaining power for computers, internet equipment, and climate control is crucial for business continuity.
• Food Preservation: A fully stocked refrigerator and freezer represent hundreds of dollars in food. Generators prevent costly spoilage during extended outages.
• Sump Pump Operation: Basement flooding during storms can cause tens of thousands in damage. Keeping sump pumps running during power outages prevents disaster.
• Home Value: Installed generators increase property value and appeal to buyers in markets like Arlington and Alexandria where power reliability is a known concern.

Understanding Generator Sizing: Essential Loads vs. Whole House Coverage

The first and most critical decision in generator installation is determining the size you need. This calculation directly impacts your initial investment, fuel consumption, and the comfort level you'll maintain during outages.

Essential Loads Approach (12-20kW Generators)

An essential loads system powers only the circuits critical for basic comfort and safety:

• Typical Coverage: Refrigerator, freezer, some lighting, furnace/HVAC blower, sump pump, garage door opener, one or two outlets per room
• What You'll Give Up: Central air conditioning (in most cases), electric dryer, electric range, multiple simultaneous appliances, whole-home lighting
• Best For: Budget-conscious homeowners, smaller homes (under 2,500 sq ft), homes with gas appliances, properties without critical cooling needs
• Typical Cost Range: $8,000-$12,000 installed

Whole House Coverage (22-48kW Generators)

A true whole house system powers virtually everything in your home simultaneously:

• Typical Coverage: Central air conditioning (up to 5 tons), electric range, electric dryer, all lighting and outlets, hot tub, well pump, multiple large appliances running simultaneously
• What You'll Get: The ability to live completely normally during extended outages without thinking about load management
• Best For: Larger homes (over 2,500 sq ft), homes with all-electric systems, properties with central AC, homeowners who demand seamless comfort
• Typical Cost Range: $12,000-$20,000+ installed

How to Calculate Your Generator Size Requirements

Follow this step-by-step process to determine your needs:

1. List Your Critical Appliances: Write down everything you absolutely must keep running (refrigerator, medical equipment, sump pump, heat/AC)
2. Find Starting Wattages: Look up each appliance's starting wattage (not just running wattage). Motors require 2-3x more power to start than to run. Common examples:
   • Central AC (3-ton): 10,000-15,000 starting watts, 3,000-5,000 running watts
   • Refrigerator: 1,200-2,000 starting watts, 150-400 running watts
   • Sump pump (1/2 HP): 2,000-4,000 starting watts, 600-800 running watts
   • Furnace blower: 1,500-2,300 starting watts, 600-875 running watts
   • Well pump (1/2 HP): 2,100-4,000 starting watts, 1,000-1,500 running watts
3. Add 20-25% Safety Margin: Never size a generator at exactly 100% of your calculated load. This reduces strain, extends lifespan, and accommodates future needs.
4. Consider Load Management: Modern generators with load management systems can strategically delay starting high-draw appliances, allowing you to power more with a smaller generator.

For most Northern Virginia homes, proper sizing typically breaks down as follows:

• Small homes (under 1,500 sq ft, no AC): 12-14kW
• Medium homes (1,500-2,500 sq ft, gas heat): 16-22kW
• Large homes (2,500-4,000 sq ft, central AC): 22-26kW
• Very large homes (over 4,000 sq ft, all-electric): 30-48kW

Fuel Type Selection: Natural Gas vs. Propane vs. Diesel

Your fuel choice significantly impacts operating costs, maintenance requirements, and installation complexity.

Natural Gas Generators

Advantages:

• Unlimited runtime (connects to existing gas line)
• No fuel storage or refilling required
• Lower operating cost per hour in most Northern Virginia markets
• Cleaner burning with less maintenance

Transfer Switch Types: Automatic vs. Manual

The transfer switch safely disconnects your home from the utility grid and connects it to generator power. This is a critical safety device preventing backfeeding that can electrocute utility workers.

Automatic Transfer Switches (ATS)

An automatic transfer switch monitors utility power and seamlessly switches to generator power when an outage is detected, then switches back when utility power returns.

Key Features:

• Automatic detection and switching (typically within 10-30 seconds of power loss)
• No manual intervention required—works even when you're away from home
• Automatic weekly self-test cycles
• Weatherproof NEMA-rated enclosure for outdoor installation
• Load shedding capabilities in advanced models

Cost Considerations:

• Transfer switch cost: $800-$2,000 depending on amperage rating and features
• Installation complexity varies based on electrical panel location and generator placement

Best For: The vast majority of whole house generator installations. This is the standard choice for convenience, reliability, and peace of mind.

Manual Transfer Switches

Manual switches require you to physically flip switches to transfer power from utility to generator.

Key Features:

• Much lower equipment cost ($200-$600)
• Requires manual operation—you must be home and physically switch it
• Must manually start portable generator
• Choose which circuits receive power based on generator capacity

Best For: Budget-conscious installations, portable generator connections, vacation homes where you'll always be present during usage, or backup to automatic systems. Generally not recommended for primary whole house generator installations.

Load Management Systems

Modern advanced transfer switches can include load management (also called load shedding) which intelligently controls which high-draw appliances run simultaneously:

• Prevents multiple high-wattage devices from starting at once
• Allows smaller generators to power more equipment
• Reduces fuel consumption
• Extends generator lifespan by preventing overload conditions
• Adds $500-$1,500 to system cost but can potentially reduce generator size requirements

Code-Required Clearances

Virginia electrical and building codes (based on NEC and manufacturer requirements) mandate minimum clearances:

• From House/Structure: Minimum 18 inches (5 feet recommended for service access)
• From Windows/Doors/Air Intakes: Minimum 5 feet (to prevent exhaust entering home)
• From Property Lines: Varies by jurisdiction (typically 3-10 feet)—check with local zoning
• From Air Conditioning Units: Minimum 3 feet (to prevent hot exhaust recirculation)
• From Combustible Materials: Minimum 3 feet from wood fencing, decks, mulch beds
• Above Flood Level: Must be elevated above 100-year flood plain where applicable

Noise Considerations

Generator noise levels vary but typically range from 62-73 decibels at 23 feet (comparable to normal conversation to vacuum cleaner).

Strategies to minimize noise impact:

• Position generator as far from bedrooms and neighbor's homes as practical
• Use landscaping to buffer sound (dense shrubs, decorative walls)
• Consider liquid-cooled models (significantly quieter than air-cooled)
• Install on vibration-dampening pad
• Review local noise ordinances (some Northern Virginia HOAs have specific restrictions)

In dense neighborhoods like Arlington or Alexandria, noise is often the biggest concern. We recommend discussing placement with neighbors beforehand, especially if the generator will be near property lines.

Fuel Line Routing

Natural Gas Installations:

• Gas line must be sized appropriately (often requires upgrade from 1/2" to 3/4" or larger)
• Line routing should be as direct as possible to minimize pressure drop
• Must include emergency shutoff valve accessible from outside
• Underground portions require proper depth (18-24 inches typical) and tracer wire
• May require coordination with gas utility for meter upgrade

Propane Installations:

• Tank must be located per local fire codes (typically 10+ feet from structures)
• Line pressure regulator required at generator
• Underground lines preferred for aesthetics and protection
• Tank size determines runtime (250-500 gallon tanks common)

Concrete Pad Requirements

Generators require stable, level mounting surfaces:

• Size: Typically 4-6 inches larger than generator footprint on all sides
• Thickness: 4-6 inches of reinforced concrete
• Gravel Base: 4-6 inches of compacted gravel beneath concrete
• Leveling: Must be precisely level for proper oil lubrication
• Cost: $400-$1,200 depending on size and site conditions

Electrical Connections and Transfer Switch Installation

Professional electrical installation is essential for safety and code compliance.

Key Installation Components

• Transfer Switch Location: Typically installed adjacent to main electrical panel, must be accessible and protected from weather
• Generator Disconnect: Required by code, allows generator to be isolated for service
• Control Wiring: Runs from generator to transfer switch, carries start/stop signals and monitoring data
• Power Conductors: Heavy gauge wiring (typically 6 AWG to 2/0 AWG depending on generator size) from generator to transfer switch

• Check for any error codes or issues
• Note runtime hours for maintenance scheduling
• Report any problems to your service provider

Frequently Asked Questions About Whole House Generators

How long will my generator run during an extended outage?

Natural gas generators can run indefinitely as long as gas service remains available. Propane generators are limited by tank size—a 250-gallon tank typically provides 2-4 days of runtime depending on load, while a 500-gallon tank provides 4-8 days. During extended regional emergencies, propane delivery may be challenging.

Will a generator power my entire house?

It depends on the generator size. A 22kW generator will power most 2,500-3,000 sq ft homes completely, including central AC. Larger homes may require 26-30kW+ for full coverage. An essential loads system (12-18kW) powers critical circuits but not everything simultaneously. We'll calculate your specific needs during consultation.

How loud are whole house generators?

Most residential generators operate at 62-69 decibels at 23 feet (comparable to normal conversation or dishwasher noise). Liquid-cooled models are quieter (57-62 dB). Proper placement minimizes noise impact on your home and neighbors. This is quieter than most portable generators (80-85 dB).

Can I install a generator myself?

While technically legal for homeowners to work on their own primary residence in Virginia, we strongly discourage DIY generator installation. The work requires electrical, gas, and concrete work, all requiring permits and inspections. Improper installation can be extremely dangerous (fire, electrocution, carbon monoxide risks) and will void warranties. See our electrical safety guidelines.

How often do generators need maintenance?

Annual professional maintenance is required to maintain warranty coverage and ensure reliability. This costs $250-$450 annually. Generators also perform automatic weekly self-tests that require no intervention. Between service visits, basic homeowner maintenance includes keeping the area clear and monitoring for issues.

What happens if natural gas service is disrupted?

While rare, natural gas service can be disrupted in major disasters. If grid power and gas service are both out, your generator won't run. This is why some homeowners in critical applications (medical needs, etc.) choose propane despite higher operating costs—it provides complete independence from utility infrastructure.

Do I need HOA approval?

Most Northern Virginia HOAs require approval for generator installation. Submit plans early in your project—approval can take 2-4 weeks. Some HOAs require landscaping screens or specific placement. We can provide documentation packages that address common HOA concerns. Denials are rare for properly planned installations.

How long does installation take?

From order to completion: 4-8 weeks typical. This includes 1-2 weeks for equipment delivery, 1-2 weeks for permit processing, and 2-5 days for actual installation work. Complex projects or utility coordination can extend timelines. We recommend ordering in late spring or early fall before storm season rush.
