NG BLU+ ECO 12,000 BTU Single-Zone Mini Split Heat Pump - 21.3 SEER2, 115V (OBMH120B / IBMH120B)

DESCRIPTION

A full ton of inverter-driven cooling and heating on a 115V circuit. This is the largest capacity NG offers at 115V, and it is the usual pick for a converted garage, a large primary bedroom, a bonus room over a garage, or an addition where running a new 240V feeder would be the expensive part of the job. Note the trade-off that comes with 115V at this size: outdoor MCA is 19.0A, so it needs a dedicated 20A circuit with essentially nothing else on it.

About the BLU+ ECO Series

BLU+ ECO systems ship as matched pairs, one indoor head and one outdoor condenser, pre-engineered to work together. They use R-454B, the low-GWP A2L refrigerant replacing R-410A under the AIM Act, and are ETL listed to UL 1995 and CSA C22.2 No. 236 and AHRI certified. WiFi control is built in.

Installation and compliance

R-454B and R-32 are A2L refrigerants, classified as mildly flammable. Installation, charging and service must be performed by a licensed HVAC contractor holding EPA Section 608 certification and trained on A2L handling. Local code may require leak detection, minimum room volume per pound of charge, or specific line set materials. Verify requirements before quoting.

Specifications are taken from the manufacturer's published data sheet and are subject to change without notice. Confirm capacity, electrical requirements and refrigerant charge against the documentation shipped with the unit before installation.

Refund & Return Policy

Return, Exchange & Limited Refund Policy

Effective Date: May 26, 2026 Willards HVAC Supply LLC | 311 Belair Rd, North Augusta, SC 29841

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.

Refunds are not guaranteed and may only be issued if replacement options are unavailable and Willards HVAC Supply elects to do so.
