How Reliable Are Generac Generators?

May 04, 2023

Generac generators are among the most reliable home backup power generators in the United States and the brand itself is top-tier. All of the Generac brands' generators  come with impressive build quality and are designed to last.

One of the best things about Generac, which helps it stand apart from other generator manufacturers, is that it considers itself a power solutions supplier. This makes their approach different as they are deliberate about addressing every element of the reliability of their on-site power production ability. Here’s everything that makes Generac a reliable brand:


To remain reliable and healthy, every generator must undergo regular maintenance to help mitigate the need for repairs. Everything from the generator fluids to the belts, hoses, batteries, and all else must be carefully taken care of regularly. This regular attention to maintenance gives the generator a lifespan of about 3,000 hours.

Some generators even have controls that let the generator owner know when the generator is due for maintenance. You will hardly find this feature elsewhere. This makes it easy to know when to contact your HVAC service provider to perform the proper upkeep and maintenance.

Be sure to hire an electrician, like us, to handle regular maintenance or else you may not get optimal results from your generator. To learn more about our maintenance plans or to schedule a service, contact us today by calling 844-216-9300 or contact us online.


The Modular Power System of Generac is a paralleled, integrated, UL power solution. It uses an integrated digital controller with a paralleling switch in the generator set connection box.

With this approach, Generac achieves the results of the single-engine solution (simplicity) while still maintaining results of the parallel generation (scalability, serviceability, and scalability). This means that no matter what your home's needs are, you can calibrate the same generator to address your power needs rather than needing a custom engine solution. 

If you are unsure how the power system will scale with your home needs, give YES! a call today at 844-216-9300. One of our technicians can help answer your questions and discuss your home's specific needs. 


Generac is in charge of constructing the engines for its generators; they are custom OHVI. As a result, the generators have a longer lifespan and you can expect to get the commensurate value for your money in terms of result and time. It is, indeed, a wise investment if you intend to use a generator for a very long time, whether for domestic or commercial purposes.

Additionally, since Generac builds their engine, they can tailor make it to the rest of the equipment which improves efficiency. Rather than relying on third party engine manufacturers which may not build specifically for their needs. YES! has seen that this approach has resulted in reliable generators that we are proud to recommend and install. 


Typically, it may take around ten years for a generator tank to get empty — this means regular fuel maintenance. If this maintenance is not taken seriously, the generator becomes unreliable. It also becomes unreliable when you run out of diesel in emergencies.

To combat this, Generac has an alternative to diesel use. There is the Bi-Fuel technology that minimizes how much on-site fuel should be maintained in the tank; it uses 75% natural gas and 25% fuel while also being able to fall back on 100% diesel during unlikely situations like gas service interruption or concurrent electricity. This solution means that you can have a more reliable generator ready for any situation.

When you decide to purchase a Generac generator, you will need an electrician to handle your generator installation. You will also need a licensed electrician to handle your generator maintenance and repair. Our experts in both Utah and Nevada are trained and ready to help you with all three.
