How Long Will A Backup Generator Provide Power To My House?

One question that we’re often asked is, “How long will a backup generator power my house for during a power outage?”. While the answer to this question depends on many factors, we’ll provide a guide that should be able to tell you how long your residential generator will run during an extended power outage.

Generator Model

The first factor that will determine how long your generator will last is the type of generator that it is. Here at RCA Electric & Generators, we’re a Power Pro Premier dealer of Generac, the most trusted and affordable generators on the market. Our Premier status with Generac means that we uphold their standards of excellence in sales, installation, maintenance, and customer service. We’re also happy to maintain any other brand of backup generator, even if we didn’t install it. 

Generator Size

The next factor that will determine your generator’s max run time is the size of the generator. The size of the generator that a home needs is determined by the house’s power usage rather than the home’s square footage. At RCA Electric & Generators, our experienced team will go through a process to determine the necessary generator size. First, we’ll conduct a thorough inspection of your current electrical system, gas load, and gas meter size. Next, we’ll discuss your specific power needs in the event of a power outage with you. Finally, we’ll make a recommendation for what generator is right for you and give you a detailed estimate. We offer generators that can either power certain circuits or your whole house, and we’ll help you decide which option is right for you.

So, How Long Will My Generator Run For?

As we said, the exact amount of time that your generator will power your house depends on your power needs and the size of the generator you have. The Generac generators we provide to our customers run on regular propane fuel tanks, which on average will last over 160 hours before they need to be replaced. Generac generators engines typically last for around 3,000 hours of use, and when properly maintained, these automatic standby generators can provide service for 30 years or more!
