Five-star reviews


“I want to thank Koppy’s Propane and Service. They did an excellent job when I asked them to reconnect my lines after I had to move the tanks for the new addition. They were timely and professional,”

“I am really quite impressed with the wonderful, professional and consistent propane delivery service I have received as a customer for10+ years. Recently I had Mike clean and service my vented fireplace unit. I’d like to acknowledge his attention to detail. Very efficient and communicated well to several questions I had. I definitely would recommend their service as a client focused, enjoyable, no-worry experience.”

“Koppy’s provides excellent all-around service. When we moved into our new house, we smelled propane. The tanks were nearly empty and we placed a call. Within an hour, a service rep arrived (Will). He was professional, courteous and replaced both of our tanks. The system was tested and the tanks filled on the next business day.”
