Most businesses rely heavily on uninterrupted power. Even a short outage can lead to missed deadlines, lost revenue, and operational chaos. While we may like to believe that outages are a rare occurrence, data suggests otherwise. 

In 2024 alone, commercial customers faced average outage costs of $6,031 per incident, with major disruptions affecting thousands and lasting longer than ever. If you do not want power disruptions to affect your business, renting a commercial generator from a reliable provider like A&J Generators could be a great idea.

However, it is important to ask a few questions before you rent the generator, or you may end up with mismatched equipment, surprise fees, or downtime when you need power most. Here are the seven key questions you must ask to ensure that you rent the right commercial generator for your needs:

What size and power capacity do I actually need?

This is arguably the most important question that you need to ask. Guessing your power requirements is a massive gamble. Remember, industrial power interruptions can be disastrous financially. For example, the estimated cost of an industrial process shutdown due to a voltage sag or short interruption averages nearly $20,000 per event, with large industrial loads suffering far higher losses. 

If you rent a unit that’s too small, you risk overloading the system and damaging your connected equipment. If you go for a generator that is too big, you will waste money on higher rental fees and burning unnecessary fuel. So, you need to calculate both the starting wattage (the initial surge needed to turn heavy machinery on) and the running wattage. If you aren’t completely sure about your load requirements, don’t guess. You can get in touch with our team at AJ Generator to help you run the exact numbers.

What type of generator is best for my application?

Not all generators are built for the same purpose. Some are designed for continuous use, while others are better suited for standby or temporary applications.

For example, a construction site may require a rugged, high-capacity unit that runs for long hours, while an event might need a quieter generator with stable output. You’ll also want to consider fuel type. Diesel generators are common for commercial use due to their efficiency and durability. Natural gas might suit indoor spots with lower emissions, but you should first check fuel availability. Understanding your specific use case will help narrow down the right option.

How long will I need the rental?

Your rental timeline dramatically impacts your bottom line. Are you looking at a weekend festival, a three-month commercial build, or standby power for hurricane season? Defining your timeline upfront helps secure the best possible rates.

More importantly, understanding your timeline dictates your maintenance schedule. A generator running continuously 24/7 for a month requires completely different upkeep and fluid top-offs than one sitting quietly on standby just in case the grid goes down.

What are the total costs involved?

The rental price is just one part of the equation. It’s important to understand the full cost, including delivery, setup, fuel, maintenance, and potential overtime charges.

Ask for a detailed breakdown so that there are no surprises later. Some providers offer bundled packages, while others charge separately for services like refueling or technical support.

Is installation and support included?

A generator is only as good as its setup. Improper installation can lead to inefficiencies or, worse, safety risks.

Check whether the rental company provides professional installation and on-site support. In many cases, having a technician handle setup and testing ensures everything runs smoothly from day one. It’s also worth asking about emergency support. If something goes wrong, how quickly can they respond?

What accessories and extra equipment are required? 

A generator is really just the engine. You still need a safe way to get that power to your tools or building. Don’t assume the rental comes with everything you need right out of the box. You have to ask about heavy-duty cables, distribution panels, transformers, and transfer switches. Finding out you are missing fifty feet of specialized cable while the delivery truck is driving away is a terrible feeling. Make a point-to-point list of how the power will travel from the generator output directly to your final connection points.

Are there any safety or compliance requirements?

Depending on your location and industry, there may be specific regulations around generator use, especially regarding emissions, noise levels, and placement.

Make sure the generator meets local compliance standards and that you understand any permits or guidelines required. A good rental company will be familiar with these regulations and can guide you through them.
