Generator Solutions Questions from Annandale Homeowners
What size generator do I need for my home?
Generator sizing depends on what you want to power. A 12-16kW generator handles essential circuits (refrigerator, sump pump, lights, internet, a few outlets). A 20-24kW unit can power most of a typical home including AC. Whole-home coverage for larger houses may require 30kW or more. We perform a load calculation to recommend the right size.
How quickly does a standby generator start during an outage?
Modern standby generators detect power loss and start automatically within 10-30 seconds. The automatic transfer switch seamlessly shifts your home from grid power to generator power without any action needed from you, even if you're away or asleep.
Do generators require regular maintenance?
Yes, standby generators need annual maintenance including oil changes, filter replacement, and system testing. Most generators run a brief weekly self-test automatically. We offer maintenance plans to keep your generator ready when you need it most.
Can a standby generator be installed with solar panels?
Yes, generators and solar systems can work together. The generator provides backup during extended outages or at night when solar isn't producing. Proper installation requires coordination between systems to prevent backfeed issues. We work with solar installers to ensure safe integration.
What fuel options are available for generators?
Standby generators run on natural gas or propane (LP). Natural gas is convenient if you have an existing gas line and provides unlimited fuel supply. Propane requires a tank but is available in areas without natural gas service. We help you choose based on your property and preferences.

Generator Solutions in Annandale Case Studies
See how we have helped homeowners across Northern Virginia with their generator solutions in annandale needs.
Whole-Home Generac Installation After Derecho Damage
colonialChallenge
After the 2024 summer derecho left their neighborhood without power for five days, the homeowners decided they could not risk another extended outage. Both adults work from home, they have a basement sump pump critical for flood prevention, and their elderly parent relies on a CPAP machine for sleep apnea.
Solution
AJ Long Electric installed a Generac 24kW whole-home standby generator on a reinforced concrete pad beside the home. We ran a new gas line from the existing meter, installed a 200-amp automatic transfer switch, and configured the system to power every circuit in the home including the HVAC system.
Result
During the next outage three months later, the generator activated within 12 seconds and the family did not lose a single minute of work or comfort. The sump pump ran continuously through the storm, preventing the basement flooding their neighbors experienced.
Essential-Circuit Generator for Remote Worker in Townhome
townhomeChallenge
A software engineer working from home needed reliable backup power for his home office, internet equipment, and refrigerator, but the townhome's compact lot and HOA restrictions limited options. The HOA required pre-approval for any exterior equipment and enforced strict noise limits of 65 dB at the property line.
Solution
We installed a compact Generac 16kW generator with the QuietTest feature, positioning it in the only HOA-approved location along the side of the unit. A 100-amp essential-circuit transfer switch powers the home office, kitchen, and network closet. We provided architectural drawings and sound specifications to the HOA for approval.
Result
The HOA approved the installation on the first submission, and the generator operates well below their 65 dB noise limit. The homeowner has maintained uninterrupted work through three subsequent power outages.
Propane Generator for Home Without Natural Gas
split-levelChallenge
The homeowners lived in a neighborhood without natural gas service and experienced four extended outages in two years. Their well pump and septic system both require electricity, meaning any outage left them without water and sewage capacity. They had been relying on a portable generator that required constant refueling.
Solution
AJ Long Electric installed a Kohler 20kW propane standby generator with a 500-gallon underground propane tank. We coordinated with a local propane supplier for tank installation, ran the gas line and electrical connections, and installed a whole-home automatic transfer switch to power all circuits.
Result
The 500-gallon tank provides approximately seven days of continuous runtime at typical load. The homeowners no longer worry about refueling during storms, and their well pump and septic system operate without interruption during any outage.
Dual-Generator System for Luxury Estate
estateChallenge
A 9,000 sq ft estate with a pool house, detached four-car garage, and extensive landscape lighting had electrical loads exceeding what a single residential generator could handle. The property also had a home theater, wine cellar with climate control, and a commercial-grade kitchen that all required uninterrupted power.
Solution
We designed a dual-generator system with a Generac 30kW unit powering the main house and a Kohler 14kW unit dedicated to the pool house and garage. Both generators connect through coordinated automatic transfer switches, and we installed a generator management system to sequence loads and prevent overloading during startup.
Result
The dual system provides complete whole-property backup with redundancy. During a 48-hour outage, every system on the property operated normally, including the pool heater and wine cellar climate control. The homeowner described it as seamless.

Colonial Homes
Common Issues
Special Considerations
Colonial homes in Vienna, McLean, and Fairfax often sit on half-acre or larger lots that provide adequate space for generator placement, but mature landscaping can complicate access. The panel location in the basement means transfer switch wiring must route from the outdoor generator through the foundation wall, requiring careful waterproof penetrations and proper conduit routing.
