Are Costco Generators Any Good? (Buy or Avoid!)

purchasing Generators from costco

My incredible relationship with Costco began when I learned that I could shop for everything under one roof. They have my favorite ice cream flavors, clothes, and shoes. If you needed to shop for everything in your house, that would be possible in one trip. But generators, that surprised me.  

I visited one of their warehouses a few weeks ago, and what I saw totally impressed me. Since I live in a remote area, I desperately needed a generator, so I decided to try Costco generators.

Are Costco generators any good?

I’ve used my new Costco generator to generate electricity for my house, charge batteries for cars, trucks, and boats. I would certainly recommend Costco generators to anyone in need of one. It’s not too noisy, and it runs smoothly and efficiently. It is exactly what I needed.

Investing in a generator needs enough due diligence. Let’s dive into more details about Costco generators to help you decide whether it’s something you should try. I’ll also tell you about Costco to know what you are getting yourself into.

How Much Does a Costco Generator Cost?

Costco is a great shopping partner because they have very affordable prices. If you ask around, many people know this store for their wholesale prices.  

Costco generators are moderately priced, especially because of their functionality. One thing to note is their variety. You can get everything from home standby generators to solar generators. It gets even better with electric start or gas-driven generators.

The most expensive generator costs $5,399.99. It has a durable all-weather aluminum closure and Wi-Fi connectivity features. If your budget is tight, go for a gasoline-powered one at $189.99.

Costco prices do not fluctuate. This is mainly because they do not spend much on advertising. Costco saves 2% annually by controlling advertising. This money is put back into slashing prices. So, you can be sure you won’t experience absurd prices at Costco.

Does Costco Have Refund Policies?

Costco offers a 100% satisfaction guarantee. Costco will refund your purchase price plus any applicable sales tax if you’re not completely satisfied with an item.

You can make the return claim through for online purchases or by returning the item to any physical Costco warehouse (there are 800 stores worldwide).

The company has a return policy that allows members to return merchandise within 90 days of purchase. This Costco return policy is not only liberal but also applies to all products, including electronics and appliances. You don’t have to worry even if you buy the wrong generator at Costco and want to return it.

Costco aims at preventing the “I wish I knew” moments customers have after buying products that later on dissatisfy them. This policy assures customers that Costco would not intentionally sell sub-standard goods.

The money Costco would spend to reimburse customers would leave them to making massive losses. No store would want that. 

Does Costco Deliver Generators?

Costco does deliver generators, which makes the store even more popular among customers. The store uses common carriers to deliver products. The service includes installation by experts. You can be sure they’ll leave you all set up.

When you order a generator online from Costco, you will have to wait a few days for it to ship out of their warehouses. Orders are typically shipped within 1-3 business days after they are placed, and it usually takes 2-5 business days for them to arrive at your home address.

Customers who need shipping to Alaska, Hawaii, or Puerto Rico will need to add a bit more for shipping and handling. The store will quote the fee at checkout.

Delivery saves customers time and money. I got my generator delivered to my doorstep. The technicians that came with it were friendly, and they set everything up. I didn’t have to lift a finger.

How Long is the Warranty on Costco Generators?

The Costco generators are a great value. They have been for years. After purchase, you have coverage for up to five years. This is a long time to get accustomed to the generator and identify any defects.

Costco and the manufacturer will not hesitate to replace or repair the generator as long as your claims are genuine. Costco’s experts ensure they do proper installations to avoid any issues that might result from improper setup.

What Is The Best Day to Shop for Generators at Costco?

The best time to buy a generator at Costco is during the months of May, June, and July. Most home improvement stores stock up on generators during spring in preparation for hurricane season, starting on June 1st.

If you’re shopping for a generator during hurricane season, be prepared to pay full price because everyone will be rushing to stores to get generators. Despite the customer rush, avoid going to Costco when the stores are packed.

Costco warehouse stores are open Monday through Sunday. From Monday to Friday, Costco opens from 10.00 am to 6.00 pm. However, I suggest that you go on a weekday afternoon between 3.00 pm and 5.00 pm.

To settle on the best generators, you need to ask enough questions, which would be harder to do if the store attendants are handling many customers at once.

Customer Reviews

Generally, people love Costco. It’s a fact. Their excellent prices, brilliant refund policy, wide variety, and impeccable customer service make Costco a customer favorite. Costco receives tons of reviews every day from people expressing how much they love the store.  

Here’s what customers had to say on

“Great generator. Quality built. Great quality built to last Yamaha motor. Very quiet. Purrs like a kitten.

I would definitely recommend this generator to my friends and relatives.”

The customer gave the generator a five-star rating.

I found one complaint on Costco’s website, but it was well resolved. A customer said:

“Can’t tell you how well this generator would have performed as it was broken in two places and I assume this was from shipping very disappointed. We waited three weeks to receive it my husband was really upset. Costco was really good about the return. The one star is for shipping.”


If you’re looking for a generator that’s both efficient and powerful, Costco is the place to go. Their generators are of great quality and affordable.

They also offer a refund policy so you can get your money back if the generator doesn’t meet your expectations. You can take advantage of this guarantee and buy their products for yourself or your loved ones.
