Very disappointed with the service offered at Rotech. We were vacationing in Arizona and the elevation affected my four-year-old medically, fragile son, and we quickly depleted our oxygen tanks. On Monday 4/13/2026 I went in person with my prescription, trying to avoid a medical emergency and having a rush to the hospital. Just needed to swap out tanks and they were unable to assist. Stated I needed to "be a member" I offered to pay for the tank swap and pleaded with them and they didn't budge. A lady with short hair said to try and contact a welding company to try and get oxygen tanks form them. I left in shock. Called local welding shop and the owner said absolutely not! The oxygen they offer is not medical grade. Customer or not, member or not, having compassion is essential in any business especially in the medical field! And to top It off, giving advice to use welding oxygen is just crazy! A simple google search you can find it can actually be poisonous! Very disappointing! We ended up being able to swap out tanks at All-Med in flagstaff. read more
