6 Common Mistakes When Buying a Home Generator to Avoid

Buying a home generator is a long-term investment that can really pay off during outages. This is especially true for Oklahoma homeowners experiencing severe storms, high winds, and sudden power outages throughout the year.

Choosing the right generator takes more thought than most people expect. Before you buy a home generator, it’s helpful to understand some common mistakes Oklahoma homeowners make.

Mistakes When Buying a Whole Home Generator in Oklahoma

Many homeowners still run into avoidable issues when buying a whole home generator in Oklahoma. 

1. Not Considering “What Size Generator Do I Need for My House?”

One of the most common mistakes is choosing the wrong size generator. Assuming a small portable generator can power everything in their home in Oklahoma. In many cases, this is not sufficient. Every appliance, light, and device draws a certain amount of power. When you add it all up, the total is usually much higher than expected. Things like your refrigerator, sump pump, HVAC system, or well pump can require a significant amount of wattage, especially when they first start up.

A practical approach before buying a home generator is to list everything you want to run during an outage. After that, check the wattage for each item, and account for the extra surge power larger appliances need at startup. If you are unsure, it is a good idea to talk to a licensed electrician or generator specialist who can help you size the system correctly.

2. Focusing Only on Price, Not Long-Term Value

It’s tempting to go for a cheaper generator since this is a significant purchase. But going with the lowest-priced option can end up costing more in the long run if the unit does not meet your needs, breaks down frequently, or is difficult to maintain. 

What really matters is reliability, fuel efficiency, and how easy the generator is to operate over time. Instead of just comparing price tags, take a closer look at reviews, warranty coverage, and the manufacturer's reputation. Spending more upfront on a higher-quality home generator unit can reduce the likelihood of repairs and improve performance over time.

3. Failing to Plan for Fuel Source and Availability

Many homeowners overlook this until they actually need the generator. Generators are not one-size-fits-all when it comes to fuel. Some are designed to run on natural gas, others rely on propane, and some use diesel. What works best really depends on what your home already has access to. For example, if your property isn’t connected to a natural gas line, a propane system might be a more suitable option. 

Additionally, you do not want to realize in the middle of an emergency that your chosen fuel source isn’t readily available or easy to maintain. Things like storage, delivery, and refill schedules all matter more than people expect. Taking the time to think through how you’ll actually fuel the generator for your home in Oklahoma ahead of time can save you from major frustration.

4. Skipping the Home Generator Installation Site Assessment

Another issue homeowners may encounter is skipping a proper site assessment, thinking they can install a generator anywhere. In reality, that can lead to many common backup generator issues later on. Without properly checking the site, you might place the whole home generator in a spot that is difficult to access, poorly ventilated, or even exposed to risks like flooding. 

There can also be hidden issues with wiring or installation that only show up after everything is set up. Taking the time to do this upfront makes a big difference in how well your system performs over time. It helps ensure the generator is installed in a spot where it can run efficiently and stay protected. It also helps avoid costly adjustments or relocations after home generator installation in Oklahoma. 

5. Not Installing Automatic Transfer Switch (ATS)

Forgetting about the automatic transfer switch is another oversight that can limit how useful your generator actually is. The generator itself is only one part of the system. The automatic transfer switch, often called an ATS, ensures everything works together smoothly. It detects when the power goes out & automatically starts the generator, then switches your home over to backup power without you having to lift a finger. 

Without it, you are left manually starting the generator, which is not ideal during bad weather or in the middle of the night. An ATS can make the entire experience much more convenient and reliable. Instead of rushing outside in the dark or dealing with manual steps during a stressful outage, the system handles everything for you automatically. 

6. Not Considering Generator Maintenance and Service Plans

Overlooking home generator maintenance and service plans is easy to do, but it matters more than expected. A home generator isn’t something you buy once and forget about. It generally requires regular maintenance to keep working properly. Basic tasks like changing the oil, replacing filters, and running occasional checks help make sure the system stays in good shape and is ready when you need it.
