Signs You Need Generator Installation & Repair

If you notice any of these warning signs, it may be time to call a licensed electrician.

Frequent Power Outages in the Area

Homes in areas prone to storms, grid instability, or aging infrastructure benefit most from standby generator protection.

Medical Equipment That Requires Power

Household members who depend on CPAP machines, oxygen concentrators, or other powered medical devices need uninterrupted electricity.

Sump Pump in a Flood-Prone Area

A power outage during heavy rain disables the sump pump, creating a high risk of basement flooding without backup power.

Home Office or Business Reliance

Loss of power during work hours disrupts productivity, internet connectivity, and can result in lost data or revenue.

Generator Not Starting or Running Rough

An existing generator that fails to start, runs unevenly, or shuts down under load needs professional diagnosis and repair.

About Generator Installation & Repair

Power outages disrupt everything — heating, cooling, refrigeration, lighting, medical equipment, home security systems, and sump pumps. A whole-house standby generator activates automatically within seconds of a power outage, restoring electricity to your entire home (or critical circuits) until utility power returns. Unlike portable generators, standby generators require no manual setup, refueling, or extension cords.

Standby generators are permanently installed outside the home and connected to the electrical system through an automatic transfer switch (ATS). When the ATS detects a power outage, it signals the generator to start and transfers the home's electrical load from the utility to the generator — typically within 10 to 30 seconds. When utility power returns, the ATS transfers the load back and shuts down the generator.

Generator sizing is critical. An undersized generator cannot power all intended circuits simultaneously, while an oversized generator wastes fuel and money. Licensed electricians perform a load calculation to determine the right generator size — considering critical loads (HVAC, refrigeration, medical equipment, sump pumps) and optional loads (lighting, cooking, entertainment). Whole-house generators typically range from 14kW to 26kW for residential applications.

Fuel options include natural gas (connected to the existing gas line — no refueling needed), propane (stored in a tank on the property), and diesel. Natural gas is the most convenient for homes with existing gas service. Installation includes the concrete pad, generator mounting, fuel connection, electrical connection through the transfer switch, and programming the exercise schedule (generators run briefly each week to stay in readiness).

Generator Installation & Repair — Frequently Asked Questions

How much does a whole-house generator cost in New York?
A whole-house standby generator installation in New York typically costs $5,000 to $15,000 including the generator, automatic transfer switch, concrete pad, fuel connection, electrical connection, and labor. The price depends on the generator size (kW), fuel type, and complexity of the installation. Portable generator hookups (manual transfer switch and inlet box) cost $800 to $2,000.
What size generator do I need for my house?
Generator sizing depends on which circuits you want to power. To run essential systems only (HVAC, refrigerator, lights, sump pump), a 14kW to 16kW generator is typically sufficient. To power the entire house including all appliances, a 20kW to 26kW generator may be needed. A licensed electrician will perform a load calculation to recommend the right size.
How long can a standby generator run continuously?
A standby generator connected to natural gas can run indefinitely (as long as gas service is maintained). Propane-fueled generators run for 1 to 2 weeks on a standard 500-gallon tank at typical household loads. Generators are designed for extended operation and include automatic oil pressure and temperature monitoring to prevent damage.
Do generators need maintenance?
Yes. Standby generators should be professionally serviced annually. Maintenance includes oil and filter changes, spark plug replacement, battery testing, coolant check (for liquid-cooled models), transfer switch testing, and load bank testing to verify performance under full load. Most generators also run a brief exercise cycle weekly (programmed during installation) to keep the engine ready.
