Installing a home generator can be a practical way to ensure continuous power during outages — but before making the investment, there are a few key questions every homeowner should consider. Whether you’re thinking about a portable option or a 24kW whole house generator, the right choice depends on your energy needs, property layout, and budget.

Here are seven important questions to ask before moving forward:

1. What size generator do I actually need?

One of the most important factors to consider is the generator’s power capacity. A 24kW whole house generator, for example, is typically suitable for medium to large homes, powering essentials like HVAC systems, refrigerators, lighting, and even electric cooking appliances. However, not every home needs that much power. Evaluate which appliances you want to keep running during an outage and consult with a qualified technician to determine the right size.

2. How much will the installation cost — and what's included?

The total cost of a home generator setup goes beyond the unit itself. Installation may involve electrical panel upgrades, permits, a fuel line connection, or a concrete pad. While it’s common to research terms like “Generac generators price” to compare options, remember that final pricing often includes labor and materials, which can vary based on your location and setup complexity.

3. What fuel type is best for my home?

Most standby generators run on natural gas, propane, or diesel. If your home already has a natural gas line, this might be the most convenient option. Propane tanks require storage space, while diesel units are typically used in rural or off-grid setups. Consider fuel availability, storage, and refueling needs when making your choice.

4. Is my electrical system compatible with a standby generator?

Not all homes are immediately ready to support a standby generator. Your existing electrical panel may need upgrades, or you might need a transfer switch to safely connect the generator to your home system. These technical aspects can impact both installation time and budget.

5. Will I need a permit or inspection?

In most areas of the U.S., installing a standby generator requires permits and inspections to ensure compliance with local codes. These rules help ensure safety and proper function. Your installer should be familiar with regional requirements, but it’s still a good idea to check with your local building authority.

6. How much maintenance does a standby generator require?

Whole house generators are not entirely hands-off. Regular maintenance — like oil changes, filter replacements, and system tests — helps ensure reliability when you need it most. Many homeowners opt for service agreements with licensed providers to handle routine checks, especially during seasonal transitions.

7. How long can the generator run in an extended outage?

The runtime of a generator depends on the model and fuel type. A 24kW whole house generator connected to a natural gas line can run continuously, while a propane-fueled system is limited by tank capacity. Make sure your system is sized and fueled according to your region’s typical outage durations.

Final Thoughts

Choosing and installing a generator is a long-term decision that impacts your comfort, safety, and budget. Whether you're comparing generac generators price ranges or evaluating a 24kW solution for full-home coverage, asking the right questions upfront can lead to better performance and fewer surprises later on.

Before you install, take time to understand your options, speak with professionals, and plan for both the expected and the unexpected.
