generac vs firman generator


As a homeowner, deciding on the right generator for your needs can be a daunting task. With so many different brands, models, and technical specifications out there, where do you even begin? Two of the most popular brands on the market are Generac and Firman. In this blog post, I will compare and contrast the features, performance, price, warranty, and support of both Generac and Firman generators to help you make an informed decision on the best option for your home.

Brand History and Reputation

Generac has been in the generator business for over 60 years, originally producing portable devices for camping and leisure before moving into the residential and commercial markets. Firman, on the other hand, is a newer player in the market, only having been established in 2003. Both brands have excellent reputations, with Generac being a household name in the industry and Firman growing in popularity due to their affordability and performance. Customer reviews for both brands are mostly positive, with many appreciating the reliability and durability of their products. Both brands have also won several industry awards, proving their expertise and commitment to excellence.

Technical Specs and Features

When comparing Generac and Firman generators, one key factor to consider is their technical specifications. Generac generators typically range from 5,000 watts to 22,000 watts, while Firman models range from 3,400 watts to 15,000 watts. Fuel tank size and runtime are also important considerations, with Generac models offering larger tanks and longer runtimes. However, Firman generators often include features such as remote monitoring and low oil shutdown not found in many Generac models.

Performance and Power

The performance and power of your generator can make all the difference in the event of an outage or emergency. Both Generac and Firman generators perform well under various conditions, including extreme weather and prolonged use. However, Generac models are generally quieter and more efficient than Firman generators, making them a more popular choice for residential settings. Generac also requires less maintenance than Firman, making them a more convenient option.

Price and Value

Cost is often a determining factor when choosing a generator, and both Generac and Firman offer different price ranges for their models. Generac generators are generally more expensive than Firman, but come with a higher level of quality and performance. Firman generators, on the other hand, are more affordable but may lack some of the advanced features and durability found in Generac models. In terms of value for money, it ultimately depends on your specific needs and budget.

Warranty and Support

Finally, it’s important to consider the warranty and support offered by each brand. Generac has a strong reputation for their warranty policy, often providing coverage for up to five years on their products. Firman offers a three-year warranty on their generators, which is still a solid warranty for the price point. Both brands also have good customer support services, however, Generac has a more comprehensive maintenance and repair system in place, which can make all the difference in emergencies.


Ultimately, both Generac and Firman generators have their own unique advantages and disadvantages. When choosing between the two, it’s important to consider your specific needs and budget carefully. While Generac is generally pricier, their models offer more advanced features and durability that are worth the investment. Firman generators, on the other hand, offer great value for the price and include innovative features like remote monitoring. Whichever brand you choose, make sure to review the technical specifications, performance, and warranty before making a final decision to ensure that you are getting the best value for your investment.
