Oxygen concentrators are machines and unfortunately, they will eventually breakdown. If you are going to own your oxygen equipment, you should have a pre-determined backup plan in the event of a power outage or mechanical failure. The first thing you should do in preparation is to have a copy of your oxygen prescription. In the event that your machine does break down, you could contact a local oxygen provider to temporarily rent a machine until yours is fixed.

No. We provide a detailed invoice when a repair is done that you can submit that information to your insurance provider for reimbursement. Most if not all insurance carriers do not offer a medical equipment repair benefit.

Whichever way you wish as long as the machine is properly packed. You can choose any carrier. Please be aware that we recommend that you insure your unit to the cost to replace the unit in case the carrier loses your package.

Please ship us your portable oxygen concentrator, the batteries that you use, and lastly your charger. We need these items to be able to recreate your problem as you have it at home or on the road. In some cases, batteries go bad, the leads to the batteries brake, and in some cases your charger will go bad. We would hate for you to send us your machine and find out that your issue is a battery or charger.

This depends on the type of equipment and issue that it may have. We do not have a blanket answer in regard to how much a repair could be.

Our turnaround time varies based on current repair requests and parts availability. Most repairs are completed within 1 week without counting shipping time. Once paid, we will complete the repair and return the machine to you.  

We accept Visa, MasterCard, and American Express
