Exchange-Only Policy

At Willards HVAC Supply, all approved returns are handled as exchange-only returns, regardless of the reason for return, including but not limited to seller error, shipping issues, wrong item received, defective merchandise, compatibility concerns, or customer ordering mistakes.

We do not guarantee refunds, and all return requests for an exchange must be made within seven days of delivery. Failure to do so will result in the rejection of your request regardless of whether the problem is due to our error or not.

Approved returns may be resolved through one or more of the following remedies, at our sole discretion:

  • Exchange for the same item
  • Replacement of the item
  • Exchange for an equivalent item of similar function or value
  • Store credit for future purchases

Limited Refund Exception

If an approved returned item cannot reasonably be replaced or exchanged because inventory is unavailable, discontinued, or otherwise not obtainable, Willards HVAC Supply may choose, at its sole discretion, to issue a refund to the original payment method.

Refunds are not guaranteed, are not a customer entitlement, and are issued only at the sole discretion of Willards HVAC Supply.

Seller Error / Wrong Item / Shipping Error

If we ship the wrong item, incorrect quantity, or an incorrectly labeled item, please notify us within 7 calendar days of delivery. Once approved, we will provide return instructions and prepaid return shipping.

Upon receipt and inspection of the returned product, we will resolve the matter through an exchange, replacement, equivalent product, or store credit, at our sole discretion.

If replacement inventory is unavailable, we may, but are not obligated to, issue a refund.

Customer Remorse / Compatibility / Wrong Part Ordered

Because HVAC products are highly technical and application-specific, returns for wrong part ordered, compatibility issues, misdiagnosis, change of mind, or pricing concerns are generally not accepted unless approved by Willards HVAC Supply.

If approved, any return resolution will be exchange-only and not a refund, except where Willards HVAC Supply elects otherwise in its sole discretion.

Defective Products / Warranty Claims

Defective items covered under our seller warranty will be resolved through repair, replacement, exchange, equivalent product, or store credit, at the sole discretion of Willards HVAC Supply.
