Customer Testimonials
Tremendous customer support from our local office staffed by Kim and Carli as well as corporate level assistance when we had questions or needed immediate help. Responsiveness, expertise from top-notch technicians like Austin and very competitive pricing make Quarles a great choice.

Quarles (Superior Fuel) has been very responsive to my fuel needs, both for my house and for my farm.
They are very fast to deliver your fuel.
Propane is delivered automatically BEFORE i run out. One less thing to worry about.
We are first time Propane users at our new home. We were not yet aware that our tank was low upon moving in and found out the hard way- lost much of our heating capacity during a frigid few days. Paul came out and filled us up and provided a great deal of info! We are grateful to him and to you, our service provider for prompt and friendly service!
Easy and efficient process in delivery service.
The price is good and the service is excellent. The gentlemen who came were very professional and friendly
We had concerns about gas, but tech was sent immediately and checked house and addressed issues. Tank was filled sooner than expected.
You delivered my propane right away on a Sunday. I am very grateful for your service. Excellent care. Thanks
The regularity of supply without prompting.
Good customer service and fast delivery service
Prompt and reliable every time!
Great service when you can make contact. Access by phone is often a challenge. After two days of trying got through and had a delivery in 36 hours. The transition from Quarles has been a frustrating experience during a challenging winter.
