Ignoring regular servicing and maintenance can result in costly repairs or replacement of parts, which can be much more expensive than the cost of routine maintenance. It can also increase the risk of generator failure during power outages, which can compromise the safety and comfort of your home. Therefore, it is important to schedule regular servicing and maintenance for your Generac generator to keep it in excellent working condition and provide you with peace of mind during power outages.

2. Factors that Affect the Cost of Servicing a Generac Generator

To understand how much it costs to service your Generac generator, you must consider the different factors that affect the pricing. These factors include the size of your generator, the type of model, the age of the unit, the level of wear and tear, and the extent of the maintenance work needed.

Size of the Generator
One of the most significant factors that affect the cost of servicing your Generac generator is its size. A larger generator requires more time and effort to maintain than a smaller one. As a result, the service cost for a 22kW generator will likely be higher than that of a 11kW generator.

Type of Model
The model of your Generac generator can also affect the service cost. Some models require more sophisticated and extensive maintenance work, and that can impact the overall price.
