Returns, Refunds & Warranty

Last updated: October 26, 2026.

Commercial-Engines.com ("we," "us," or "our") is a trade name (DBA) of Viom Global Inc, a subsidiary of Revenue Dealer Martech Private Limited. We connect customers with third-party suppliers and do not process payments directly. Each supplier maintains its own warranty, refund and return policy, which governs your purchase and is stated on your quote and invoice before you commit.

Orders may be cancelled immediately after they are placed, before the supplier begins fulfillment. Once a supplier has begun processing, preparing or shipping the unit, a cancellation request may no longer be accepted. Orders that have already shipped are handled under the supplier's return policy. To request a cancellation, contact us as soon as possible with your order details so we can relay the request to the supplier.

• Report any damaged or defective unit within the timeframe stated on your quote or order confirmation
• If a unit does not match its description, notify us on the same day you receive it to remain eligible for review
• Reports made after these windows may not qualify for a refund or replacement
• Freight damage must be noted on the delivery receipt before signing (see Shipping & Freight)

Any warranty that applies to your unit, including its length and what it covers, is provided by the supplier and written on your quote and invoice. We do not advertise blanket warranty terms. Warranty coverage usually requires proper installation and may require installation records.

If a core is required, the quote states the return period, condition requirements and core refund amount. Cores must be returned complete and drained, in the condition stated on the quote.

Where a refund is approved by the paying party, it is typically processed within 1–2 business days. The time for funds to appear in your account depends on your bank or card issuer.

While we cannot process refunds on behalf of suppliers, if you have an issue with a supplier, contact us and we will do our best to assist.

• Contact us or the supplier as early as possible with your order details
• Refer to the supplier's refund, return and warranty terms on your quote
• Keep all quotes, invoices, delivery receipts and communication records
