FAQs
Why should I consider a standby generator for my Harrison home or business?
Harrison and the wider Westchester County area experience severe thunderstorms, heavy snow, and periodic utility work that can interrupt electric service for hours or even days. A permanently installed standby generator detects an outage within seconds and automatically restores power, keeping critical systems such as heating, refrigeration, medical equipment, and security running. It eliminates the safety risks of candles or portable generators, protects valuable electronics from power-surge damage, and can even reduce insurance premiums.
How do I determine the correct generator size for my property?
Sizing is based on the total running wattage of the appliances you want to back up and the brief surge wattage some motors need to start. We begin with a load calculation that lists essentials—furnace, refrigerator, well pump, sump pump, lighting, Wi-Fi, etc.—and add up their requirements. For a typical Harrison single-family home, this ranges from 14 kW to 24 kW. Larger estates and commercial sites may need 30 kW to 150 kW or more. Our technicians perform an on-site assessment, model future expansion, and recommend the most efficient unit so you never over- or under-buy.
Will a generator power my entire house or just selected circuits?
You have two options. Whole-house systems use an automatic transfer switch sized to your service panel (usually 200 A) and will supply every circuit, making the outage essentially invisible. Alternatively, a managed-load or essential-load setup powers only pre-selected circuits such as HVAC, kitchen, and internet, keeping the generator smaller and the upfront cost lower. We design both solutions and can upgrade a managed system to whole-house later if your needs change.
What fuel options are available and which is best in Harrison?
Standby generators commonly run on natural gas, liquid propane (LP), or diesel. • Natural gas: Most popular in Harrison because many neighborhoods already have NG service. Fuel is continuous, no refilling required, low emissions. • Liquid propane: Ideal for homes without natural-gas lines. Propane stores indefinitely in an on-site tank and burns cleanly. Tank size (250–500 gal) determines runtime. • Diesel: Preferred for larger commercial generators (30 kW+) due to higher energy density and reliability, but tanks require regular fuel-quality checks. We evaluate utility access, runtime goals, and local code to recommend the best fuel.
How often does my generator need maintenance and what services do you provide?
Manufacturers recommend an annual professional service or every 150-200 run hours, whichever comes first. Our maintenance plans include: 1. Full visual and electrical inspection 2. Oil, filter, and spark-plug changes 3. Battery load test and terminal cleaning 4. Firmware updates and controller diagnostics 5. Load-bank testing to verify real-world performance We’ll also schedule semi-annual quick-checks, keep a digital log for warranty compliance, and provide 24/7 emergency repair across Harrison if an alert code appears.
How long does installation take and do you handle permits and inspections?
From signed proposal to final commissioning, residential installations usually take 2–3 weeks. The actual on-site work is completed in 1–2 days: day 1 for pad setting and electrical/gas rough-in, day 2 for transfer-switch wiring, startup, and customer orientation. We manage every municipal permit with the Town/Village of Harrison, coordinate Con Edison or natural-gas upgrades, and schedule the electrical and plumbing inspections. Once the inspector signs off, we register your warranty and enroll you in our remote monitoring program.
