2023 Costco Generator Cost, Installation, Reviews

Costco is the go-to store for many homeowners because it offers a wide range of products, including generators.

Since there are numerous types of Costco generators, learning more about their advantages, drawbacks, and prices could help you make an informed decision.

Average Cost Of Costco Generators

The total average cost of installing a Costco generator ranges between $1,390 and $7,961.

Why is there such a big price difference? Because the total costs depend on many factors like the unit’s size and type, labor costs, and permits.

Costco Generator Cost By Size

One of the biggest factors that determine the final price of installing a new generator is the unit’s size (or capacity).

The size of a generator is typically expressed in watts (W) or kilowatts (kW). One kilowatt is 1,000 watts.

Generators with a capacity between one and six kilowatts usually cost $475 to $1,710. These units are enough to power an appliance or several lights, but they can’t handle anything more than that.

Next in line are generators with a capacity of 7-10 kilowatts. The average price of generators this size is $2,185 to $3,325, and they can power a few appliances, up to 10 lights, or a sump pump.

The cost of generators with a 14-18-kilowatt capacity is somewhere between $3,800 and $5,525. These units are enough for medium-sized homes up to 1,500 square feet.

Then, we have generators that feature a capacity of 20 to 25 kilowatts. Their average price is $4,275 to $11,875, and they can provide power to 3,000 to 5,000-square-foot homes.

There are also beasts of generators with capacities of 30, 40, 50, 100, and even 150 kilowatts. The price of such generators ranges from $6,700 for 30 kW generators, to over $48,000 for 150 kW units.

Size	Cost
1-6 kW	$475-$1,710
7-10 kW	$2,185-$3,325
14-18 kW	$3,800-$5,525
20-25 kW	$4,275-$11,875

Keep in mind that Costco doesn’t sell such powerful generators. The retailer mostly focuses on generators from the first two categories (1-6 kW and 7-10 kW generators).

The most powerful generator Costco currently offers has a capacity of 22 kW, and it costs $5,399.99.

Pro Tip: Costco often has great sales on generators, and you can save hundreds of dollars if you catch one. It may be a good idea to check with a Costco employee if they know of any upcoming sales.

Costco Generator Cost by Fuel Type

Generators operate using different fuel types.

At the time of writing, Costco offers generators operating on:

• Gasoline
• Natural gas
• Liquid propane
• Solar energy

Costco Gasoline Generators

Generators that operate on gasoline are typically the most affordable option, with an average price of $475 to $1,400.

While the unit’s price is low (compared to generators that use other fuel types), operating costs can be quite high. This is due to the rising price of gas.

Since they don’t have a big tank, gasoline generators have a limited run time.

Costco Natural Gas Generators

Generators fueled by natural gas need to be connected to the city’s gas line.

Therefore, you can’t purchase a portable natural gas generator.

The average price of such generators ranges between $850 and $1,400 at Costco.

Costco Liquid Propane Generators

Liquid propane generators can be used as portable and whole-house units.

They’re an excellent option for those looking for a greener solution; compared to gas and diesel, liquid propane is clean-burning.

Plus, liquid propane generators don’t require a gas line, so they’re great for those living in rural areas.

Depending on the type you opt for, you can expect the price to be anywhere between $700 and $2,600 for liquid propane generators at Costco.

Solar Generators

Since they use solar power to operate, these generators are the most eco-friendly option.

They’re ideal for those living in areas that get a lot of sun throughout the year.

Costco offers several solar generators.

Their average price is $1,200 to $1,800.

While this may sound affordable, it’s important to emphasize that these are low-capacity units that can’t power more than a few appliances.

Unlike gas generators, some solar powered generators are portable.

Did you know? Solar generators may have higher initial costs, but they pay off over time since they require minimal maintenance and don’t need any type of fuel to operate. But keep in mind that the investment isn’t worth it if you get a lot of cloudy weather since this affects the generators’ efficiency.

Costco Dual Fuel and Tri Fuel Generators

Costco has several dual-fuel generators.

As their name indicates, they can operate on two fuel types.

You can choose units that work on gasoline and liquid propane or those that use liquid propane and natural gas.

Depending on their capacity, these models can cost between $840 and $5,400.

At the time of writing, Costco offers one model that can operate on three fuel types: natural gas, liquid propane, or gasoline.

Types Of Costco Generators

Fuel type and size (capacity) aren’t the only criteria we can use to classify generators.

You’ll often come across the portable/partial/whole house distinction.

Portable generators are small and compact and don’t require a connection to a gas line.

Their main advantage is their portability. You can take them to any location where you need power.

Or you can use them as backup options in case of a power outage.

Keep in mind that the portable generators have a small capacity and can only power essential appliances and lights.

Partial (critical system) generators are ideal for powering several essential appliances like refrigerators, microwaves, and lights.

They can be an excellent cost-effective solution for many families.

As their name indicates, whole-house generators can power an entire house.

They’re the most expensive and largest option of the three, but they offer unmatched capacity.

Additional Costs To Consider

The prices we’ve mentioned above are only for the unit. There are other costs you should consider, including:

Labor

Labor costs for setting up a generator range from $1,425 to $4,750.

How much you’ll have to pay for labor depends on the size of the generator, the location of the installation, your location (contractors in urban areas tend to have higher rates), and the complexity of the project.

Since labor costs can add a lot to the final price, some homeowners may consider performing the installation themselves.

This is not recommended for those who lack professional experience and the right tools.

Installing a generator involves connecting it to the home’s electrical system.

If you’re not 100% sure what you’re doing, you could end up causing significant damage and/or severe injuries.

Even if you manage to install the generator, there’s no guarantee it will function properly.

Pro Tip: Instead of thinking about paying for a professional installation as an expense, consider it a wise investment. It will give you security and peace of mind.

Concrete Pads

Generators are typically installed on a concrete pad because for stability and security.

If you don’t have a concrete pad, you’ll need to pay an additional $47.50 to $72.50 per square foot to set it up.

Naturally, the larger your generator, the more expensive the concrete pad will be.

Location

The location affects the price of the project in two ways.

First, labor costs are typically higher in urban areas. So, if you live in a large city like New York or San Francisco, you can expect to pay more for labor.

Second, the future location of your generator also has a role in the final price.

If you want to install the generator further away from the fuel source, the contractor will need to create a longer connection, which affects labor costs.

Transfer Switch

A transfer switch connects your generator to the city’s electrical grid.

The two types of transfer switches are manual and automatic, and the prices range from $760 to $1,900 (including labor costs).

Permits

You’ll probably need permits for any electrical upgrade.

Depending on your local building codes, a permit can cost you $47.50 to $190.

Electrical Upgrades

Before installing a generator, you need to ensure that your home’s electrical system is in top condition. You may have additional costs to upgrade it.

Common upgrades include installing an electrical subpanel ($503 to $1,900) and adding a circuit ($475 to $950).

Operational Costs

The expenses don’t end with installing a generator.

Being aware of the costs of running and maintaining a generator will help you decide on the best option.

Let’s explain operational costs using a 20 kW generator as an example.

If you have a generator that uses natural gas, daily operational costs will be around $85.

This is affordable compared to 20 kW diesel and propane units, whose daily operational costs are approximately $167 and $209, respectively.

Maintenance

If you want to keep your generator in excellent condition, you have to maintain it regularly.

The best action you can take in this sense is to hire a professional to inspect and service your generator once or twice a year.

An inspection will cost you around $76 to $285.

It’s best to schedule maintenance before winter and/or summer.

Enhancements and Upgrades

Many homeowners decide to upgrade their generators at some point to make them easier to use.

For example, you can install a wireless monitor allowing you to check your generator’s status remotely. The price of such a monitor is between $190 and $380.

Or you can set up a smart load manager that ensures your generator doesn’t overload. If you want this enhancement, you’ll need to pay $142.50 to $285.

Does Costco Install Generators?

Costco works with a network of independent contractors who can install the generator you purchased from the retailer.

The first thing you need to do if you want to take advantage of this option is to request an in-home consultation.

A certified generator consultant will come to your home, take measurements, discuss your requirements and preferences, and suggest the best solution.

You’ll be presented with the approximate cost of the project.

Once you accept the offer, you’ll schedule the installation in agreement with the dealer.

Keep in mind that the availability of installation services by Costco contractors depends on your location.

In some areas, Costco doesn’t offer installation.

As far as the installation costs go, it’s impossible to predict because they depend on many factors.

Did you know? Costco offers free in-home consultations. Therefore, there’s no reason not to schedule one and get an expert’s opinion on the best option for your home.

Costco Generator vs Home Depot

Home Depot is one of the most popular home improvement retailers in the U.S.

Like Costco, Home Depot also sells a wide range of high-quality generators.

The first criterion we’ll use to compare the offers from these two companies is the selection, and Home Depot takes the win.

The home improvement retailer offers over 350 generators, from small, portable units to robust models with exceptional capacities.

In fact, Home Depot carries almost the same brands as Costco (except Honeywell, Lion Energy, and A-iPower).

In addition to these, Home Depot offers generators from companies such as:

• Champion Power Equipment
• Duromax
• Milwaukee
• Pulsar
• Honda
• Kohler
• EcoFlow

The most powerful units Home Depot offers feature 26 kW and cost $6,197 to $6,997.

Now let’s compare the prices.

Both Costco and Home Depot offer models varying in price, allowing all homeowners to find a unit that matches their budget.

Another important factor is customer service.

According to online reviews, both Costco and Home Depot customers are satisfied with the provided services.

Moreover, both companies offer generator installation services (depending on your location), and many people praise them.

As you can see, the only real distinction between Costco and Home Depot is the selection.

Costco Generator vs Lowes

Lowe’s is a popular home improvement company that carries thousands of products, including generators.

Which company has better generators, Costco or Lowe’s? That depends on whom you ask.

If we look at the versatility of generators, Lowe’s is the winner.

The company features hundreds of generators from various brands. They stock some of the brands that are also available at Costco, such as Generac, Jackery, Firman, Briggs & Stratton, Geneverse, and A-iPower.

Besides those, Lowe’s offers generators from these brands:

• Honda

• Simpson
• Southwire

The list goes on and on.

Lowe’s has an extensive offer of high-capacity generators, including a few with 26 kW. Prices for these beasts range between $6,000 and $7,800.

The next factor that could help you determine whether to buy a generator from Costco or Lowe’s is customer service.

Both companies recognize the importance of great customer support and invest a lot in training their employees.

That being said, it seems that people prefer Costco’s customer support.

The Costco team is professional, helpful, and quick.

Several online reviews by Lowe’s customers state that they weren’t happy with the service they got because the employees seemed uninterested or not knowledgeable on the topic.

Both Costco and Lowe’s offer generator installation services and both companies state that the availability of these services depends on your location and the selected product.

As far as the prices go, we can say they’re fairly similar.

According to customers, it seems that Lowe’s has sales and discounts more frequently, so this may be worth looking into.

Did you know? Lowe’s has more than 1,700 stores in the U.S. and employs more than 300,000 people!

Generate The Power

Although they may not have a wide selection like Lowe’s or Home Depot, Costco may be the best option for purchasing a generator.

They carry several generator brands known for their reliability, tradition, and quality.

Plus, they offer professional installation services (in some areas) and have great terms and online reviews.

The price of Costco generators varies, so homeowners can find numerous models that fit into their budget.
