Frequently Asked Questions About Potomac Generator Service & Repair, Inc
How do I know if I need a standby generator?
A standby generator is a smart investment if you face regular power outages, run a home office, depend on medical devices, or want to safeguard your property from sudden electrical failures. It delivers dependable, automatic backup power without managing extension cords or portable equipment.
What's the difference between a portable generator and a standby generator?
Portable generators need manual setup, refueling, and connection each time the power goes out. Standby generators are permanently installed and wired directly into your electrical system, activating automatically within seconds of an outage with no manual intervention.
How long does it take to install a generator?
Standby generator installations typically take 1-3 days to complete, depending on site preparation requirements, permit processing, and utility company coordination. We manage every step of the process, from initial consultation through installation and final system testing.
What size generator do I need for my home?
The appropriate generator size depends on your home's square footage, critical appliances, heating and cooling systems, and overall electrical demand. We conduct a detailed load assessment to recommend a properly sized system that meets your specific needs.
Do generators require maintenance?
Yes, generators need regular maintenance to remain dependable. We suggest scheduling service annually or twice per year, which includes oil changes, comprehensive system inspections, and performance evaluations to confirm your unit will operate properly during an emergency.
How often will my generator run?
Your generator activates automatically whenever power is lost and typically performs weekly self-diagnostic tests to maintain readiness. These tests run for a short time and help detect potential problems before an actual emergency occurs.
What fuel source do standby generators use?
Standby generators generally operate on natural gas or propane. If your property is already connected to a natural gas supply, that's usually the most practical choice. We'll assist you in selecting the best fuel option for your situation.
Can a generator power my entire home?
Yes, depending on your generator's capacity. Whole-home systems can supply power to all circuits, while smaller units can be configured to support critical systems such as heating, refrigeration, lighting, and medical devices.
How much does a standby generator cost?
Pricing depends on the generator's capacity, installation requirements, and fuel type. Most complete installations range from $8,000 to over $20,000. We provide clear, detailed estimates tailored to your specific project so there are no surprises.
Do you offer maintenance plans or service after installation?
Yes, we provide comprehensive maintenance and service plans to keep your generator operating reliably. Our technicians are available for scheduled inspections, repairs, and emergency service to ensure your continued protection and confidence.
