Generator Install questions, answered by experts

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit
