REVIEWS FROM OUR CUSTOMERS

Testimonials

Eric
Excellent Experience

Excellent experience and extremely prompt and professional service. I had the privilege of speaking with Debbie and she reviewed current inventory, shipping times and payment options with me. I was shocked (no pun intended) when the Cummins QuietConnect showed up just 2 days after I spoke with the company. Amazing as most places told me I may get it for Christmas or by New Year's if I'm lucky (6-7 month wait time). Highly recommend Buckeye Power Systems without hesitation. Prompt, Professional and delivering what others cannot.

Cathy
Received Sooner than Expected!

We ordered a generator from Buckeye Power Systems. Misti and Tracy were excellent to work with and both were very helpful and friendly. Our generator was received sooner than expected.

Thank you for all your help and great service.

Jeffrey
That is what we call "Customer Service"!

I’ve been searching for honest answers on my quest to buy a standby generator. I have a son who is Autistic, any disruptions that interrupt his routine can be quite the ordeal during an outage.

Since the Pandemic began, companies have been overwhelmed with demand, and many just don’t take the time to spend any time to guide you on which one will fit your needs, EXCEPT David with Buckeye Power Systems.

I was on my way to work and asked David if I could call him back the next day? Well, David called ME back the next day and gave me excellent info on what I need for my specific home, and probably spent 30 to 45 minutes on the phone with me. THAT FOLKS, IS WHAT WE CALL, CUSTOMER SERVICE!!!!!

I live in southeast Texas and will definitely buy my generator from David with Buckeye Power Systems in Cordova, TN.

William
Above and Beyond!

These folks will go above and beyond to help you with your Generator service needs. I highly recommend them and am grateful for their help getting our Onan generator repaired.

Frequently Asked Questions

FAQ

What size generator do I need?

The Buckeye Power Systems staff can help with generator sizing for residential and business applications.

For homeowners, we will likely ask a few questions such as:

Are you looking to cover the whole house or just the essentials?

What is your home's square footage?

How many air conditioners do you have and do you need to power all of them or just one or two? It also helps to know the tonnage of the A/Cs (i.e., 3-ton, 5-ton).

Does you home have one main breaker panel or multiple panels? What is the size of the Main Breaker (typically 200-Amp)?

Are you on city water or do you have a well pump?

What about pool and sump pumps?

We may have more questions but answers to the above should help us in guiding you to the perfect Cummins standby generator for your home.

What are my payment options?

We can draft payments from your checking account. We also accept all major credit cards.

What About Shipping?

Shipping costs will vary, depending on your location. We ship from Cordova, Tennessee - a suburb of Memphis.

Please call us for a firm shipping quote.

Once your payment is processed, your new Cummins generator will be shipped to your location. Typical ship times will vary depending on your location (usually 2-5 business days).

Do you charge Sales Tax?

Most states are shipped tax-free. Exceptions include Tennessee, Michigan, and Louisiana.

How can I learn more about standby power systems?

Visit our Helpful Resources section where you will find a complete list of helpful articles about standby power systems.
