Finding the Right Fit Starts with Asking the Right Questions

But the hard part isn’t deciding whether you want backup power. It’s figuring out which generator is right for your Tennessee home. From the size of your house to the appliances you want to keep running, several factors can influence your decision.

Start With What You Want to Keep Running

Every household uses electricity a little differently, which is why there’s no one-size-fits-all answer when it comes to choosing a generator. For some homeowners, keeping the refrigerator, a few lights, and the HVAC system running is enough to stay comfortable during an outage. Others may want backup power for a well pump, home office, medical equipment, or nearly the entire house.

The more you expect your generator to power, the larger the system will likely need to be. That’s why it’s helpful to think about your priorities before comparing generator models. Take note of which appliances and systems are most important to your household to get a better starting point for choosing a generator that’s sized for your needs. However, the more propane appliances you have (such as a propane water heater or clothes dryer) the less electricity demand there will be on your generator.

Think About Where Your Generator Will Go

A standby generator isn’t something you can place just anywhere in the yard. Before installation, several factors need to be considered, including local building codes, required clearances from windows and doors, ventilation requirements, and access to your home’s electrical and propane systems.

The location also needs to be practical. Your generator should be easy to access for routine maintenance and future service without creating obstacles around your home. Thinking about placement early can help avoid surprises once you’re ready to move forward with installation.

Don’t Overlook Your Propane Supply

It’s easy to focus on the generator itself, but your propane supply deserves just as much attention. The size of your propane tank, the generator you choose, and how much electricity you’re using during an outage all affect how long your backup power system can run.

If your home already uses propane, your existing tank may be able to support a standby generator. Depending on your current setup and the generator you choose, a larger tank or additional propane storage may be recommended.

Before your generator is installed, your propane provider can evaluate your current setup and determine whether any updates are needed.

Ask Questions Before You Compare Generators

It’s easy to get caught up comparing brands, features, and generator sizes, but those details matter much more once you understand your home’s needs. Before you start looking at specific models, ask yourself a few simple questions:

  • What do I want to keep running during an outage?
  • How long do I expect to rely on backup power?
  • Am I planning any changes to my home that could affect my electrical needs?
  • Does my current propane system support the generator I’m considering?

Having those answers before you start shopping can make the decision much clearer and help you focus on generators that truly fit your home.

Making an Informed Decision

The more you understand before you begin shopping, the easier it becomes to compare your options with confidence. Knowing what you want your generator to do, how much backup power your household needs, and how propane fits into the overall system can help you make a decision that’s practical and built around your home.
