Your Backup Power Questions, Answered
Resources & Expert Guidance
Annual maintenance service.
One-time use per person.
The only accurate answer comes from a proper load calculation, not guesswork based on your home's square footage or "what your neighbor has." We measure your actual electrical loads, account for simultaneous use patterns, and size accordingly. A 22kW system might be perfect for one 3,000 sq ft home but completely wrong for another identical house with different electrical needs. This is why we prioritize on site visits before providing quotes.
Whole-house systems power everything simultaneously: all AC units, kitchen appliances, well pumps, everything. Essential circuit systems cover critical loads: refrigeration, heating/cooling (usually one zone), lights, outlets for medical equipment or work-from-home setups. The honest truth? Many families don't need whole-house backup. We'll help you identify your critical needs and design accordingly, saving you headaches and unnecessary worries.
Each has advantages depending on your situation:
We'll assess what's available at your property and recommend the most practical fuel source.
Legally, no. Maryland, Virginia, and DC jurisdictions require licensed electricians for generator installations. More importantly, improper installation creates life-safety hazards: carbon monoxide risks, back-feeding into utility lines (dangerous for linemen), fire hazards from incorrect fuel connections, and voided warranties. Professional installation isn't just a good idea, it's required by code and insurance policies.
With proper maintenance, residential generators typically run 20-30 years. We service units from the 1990s that still operate reliably. Key factors:Â regular comprehensive maintenance (annual minimum with 60+ point inspection), proper installation, fuel quality, and usage frequency. Commercial units may require replacement sooner but typically deliver 15+ years with good maintenance programs.
From contract signing to operational system: typically 2-4 weeks. This includes permit acquisition (1-2 weeks depending on jurisdiction), equipment delivery, installation (usually 1-2 days), inspection, and final approval. We can expedite for emergencies, and we handle all permit coordination, you never have to call Montgomery County DPS or Fairfax DEP yourself.
Yes, permits are required in every jurisdiction we serve. We handle everything: permit applications, scheduling inspections, code compliance verification, and communicating with inspectors. Each jurisdiction has different requirements, Loudoun County Building & Development operates differently than Alexandria permits, which differs from Anne Arundel County processes. We know them all.
We take reasonable precautions to minimize impact, but some disruption is unavoidable. We'll discuss placement that balances: noise considerations, utility access for repairs, clearance requirements, future property plans (that deck you're thinking about), and minimizing trenching through established landscaping. If you're particularly attached to specific plantings, tell us during the consultation—we'll work around your award-winning hydrangeas.
This is common in older homes—especially those built before modern electrical loads (EV chargers, multiple AC units, electric ranges). If your panel needs upgrading, we tell you during the consultation, not on installation day. Panel upgrades add cost and time but are sometimes necessary for safe generator integration. We provide complete electrical services including heavy-ups from 100-amp to 200-amp service.
Usually yes, but HOAs often have specific requirements: noise levels, placement restrictions, visual screening, even specific equipment colors. We've navigated HOA approval processes throughout McLean, Potomac, Great Falls, and similar communities. Bring your HOA covenants to the consultation, we'll design a compliant installation and provide documentation for HOA submission.
For residential installations in our service area, budget $8,000-$25,000+ depending on: system size (14kW to 26kW+), fuel type and availability, electrical work required, permit complexity, site conditions, and optional features like cold weather kits or enhanced sound enclosures. We provide detailed proposals breaking down all costs: equipment, installation, permits, electrical work, everything. No surprises.
Yes, particularly in markets that experience regular outages. Real estate professionals in our area report buyers specifically ask about backup power systems. The ROI varies by market, but properly installed Generac systems typically add value to homes, especially in areas with storm vulnerability or buyers who work from home.
Our comprehensive 60+ point inspection covers four critical areas:
This requires specialized diagnostic equipment many companies don't maintain: cooling system pressure testers, resistance meters, voltage calibration tools. Commercial systems may need more frequent service based on runtime. View complete maintenance details.
Yes, we work with several financing partners offering terms for qualified buyers. Generac also offers financing options through their network. We'll discuss financing during your consultation if relevant to your situation.
Basic checks yes, comprehensive service no. You should listen during weekly exercise cycles, visually inspect for leaks, and keep the area clear. Leave the 60+ point inspection to professionals, it requires specialized diagnostic equipment (pressure testers, resistance meters, calibration tools) and factory training. Improper maintenance voids warranties and creates problems we then fix during emergency calls. See what we include in professional service.
We don't offer "oil change specials", we perform 60+ point inspections using specialized equipment most companies don't maintain. While competitors do basic visual checks and fluid changes, we pressure-test cooling systems, resistance-check power heads, calibrate voltage output, and inspect transfer switch components. Our factory-trained technicians use diagnostic equipment to catch problems before failures occur. We document everything with before-and-after photos. Generators are our specialized focus - not a side business, which means we have the equipment, certifications, and expertise to do it right. See our complete generator maintenance approach here.
It means when you call at 2am because your generator won't start and your power has been out for 6 hours, we answer the phone. We'll troubleshoot remotely if possible (many issues can be simple fixes we can walk you through). If necessary, we dispatch a technician, typically within an hour under normal conditions. During widespread outages affecting hundreds of customers, we prioritize: life-safety situations first, then service in the order received. But we always answer the phone.
Yes. Our technicians are certified on Generac and Kohler, and we service most major brands including Briggs & Stratton, Cummins, and Caterpillar. If it's a generator, we've likely worked on it. Some older or uncommon brands may require parts ordering, but we can diagnose and service them.
First, don't panic. Call us: 443-BESTGEN (443-237-8436) - we answer 24/7. Before calling, check these quick items if safe:
Have this information ready when calling, it helps us diagnose faster.
Usually a transfer switch issue. The generator might be running perfectly, but the switch that disconnects from utility and connects to generator power isn't engaging. This can be: transfer switch failure, utility voltage still present (fooling the switch), or control wiring issues. This requires professional diagnosis, call us immediately.
Common causes: low oil pressure (often a failed sensor, not actual low oil), overheating, overcurrent from excessive loads, or fuel supply issues. The generator's safety systems are working correctly by shutting down to prevent damage. Don't keep restarting, call us for diagnosis. Repeatedly restarting can damage components.
Generators make noise, that's normal. Concerning sounds include: loud knocking (possible bearing issues), grinding (starter problems), or excessive vibration (mounting or internal issues). If it sounds different than normal, or if noise levels have increased significantly, schedule service before it becomes an emergency during an outage.
Yes, and it should automatically. Your generator has an exercise cycle (typically weekly) where it runs for 15-20 minutes to: circulate fluids, charge the battery, verify operational readiness, and prevent fuel system problems. If you're not hearing weekly cycles, something's wrong. Exercise cycles are essential for reliability.
Recommended steps:
If your generator is properly maintained and installed:
You literally do nothing. That's how automatic transfer switches work when maintained properly.
No. If you have a natural gas generator and your gas supply is disrupted (rare but possible), you have no backup power. This is one reason some customers choose propane, it's onsite and not dependent on utility supply. However, natural gas outages in our service area are extremely uncommon compared to electrical outages.
Yes. Professional EV charger installation including capacity assessment, permit acquisition, and electrical integration. We handle wallbox chargers for residential and commercial applications. EV charger installation can be standalone service or integrated with generator systems, ensuring your EV charges even during extended outages.
We install and integrate battery wall systems including Generac PWRcell. Battery systems provide seamless backup power and can operate independently or as part of a complete energy ecosystem with solar and generator integration. Battery systems work well for apartments, high-rises, or homes where traditional generators aren't feasible.
Yes. We coordinate complete energy ecosystems: solar power with battery storage and backup generators, ensuring optimal performance and seamless transitions between power sources. This is increasingly popular in our service area as customers seek energy independence and backup power.
Absolutely. Our Master Electrician credentials and experience mean we handle heavy electrical work: service upgrades (100-amp to 200-amp), panel replacements, and major installations. Many customers start with panel upgrades to support EV chargers or increased electrical loads, then add generators later. We refer smaller residential electrical work to trusted partners while focusing on our expertise areas.
Three decades of diagnostic expertise, not salespeople chasing commissions. We've fixed generators for $42 that other companies said needed $12,000 replacements.
