HVAC Mirage | 12,000 BTU | 23 SEER2 | Wall Mounted | Indoor Air Handler | 115V | IMZH120C

A 12,000 BTU, 115V wall-mounted indoor air handler engineered for single-zone ductless mini split systems—ideal for homeowners and HVAC professionals fitting one room or open-concept space up to ~550 sq ft where a standard wall outlet circuit is already in place.

HVAC Mirage Ventus X Series — 12,000 BTU Wall Mounted Indoor Air Handler

The HVAC Mirage Ventus X Series IMZH120C is a 12,000 BTU (1.0-ton), 115V wall-mounted indoor air handler rated at 23 SEER2. Designed for single-zone ductless mini split applications, it pairs with a compatible Ventus X Series outdoor condensing unit to deliver inverter-driven variable-speed comfort in spaces up to approximately 550 square feet. The 115V operating voltage makes it suitable for standard single-phase residential circuits—an important advantage for retrofit installations where a 208/230V dedicated circuit is not readily available.

Wireless Remote Control

Note: Outdoor condensing unit, line set (3/8" liquid × 7/8" suction), mounting bracket, disconnect box, and all electrical wiring are NOT included and must be purchased separately.

Installation Requirements & Accessories

• Voltage: 115V / 60Hz / Single-Phase — requires a dedicated 115V circuit. NOT compatible with 208/230V-only circuits.
• Required Line Set: 3/8" liquid line × 7/8" suction line — sold separately. Length must be confirmed against the matched outdoor unit's maximum line set run specification.
• Refrigerant: R-410A, factory pre-charged at the outdoor unit. Professional recovery equipment required during service (EPA Section 608 mandatory).
• Outdoor Unit: NOT included. Must be a compatible HVAC Mirage Ventus X Series outdoor condensing unit — AHRI-certified match required for rated efficiency and warranty validity.
• Mounting Bracket: NOT included — purchase a manufacturer-specified wall mounting bracket separately.
• Electrical Wiring: NOT included. Use 14/4 AWG stranded copper communication/power wire between indoor and outdoor units per local electrical code and manufacturer instructions.

Pro-Installer Tip

When making flare connections on the 3/8" liquid and 7/8" suction service ports of the IMZH120C, use an eccentric flaring tool — not a standard block-style tool — to produce a consistent, concentric flare seat that seals without micro-fractures. Undertorqued flares on the larger 7/8" suction line are the leading cause of slow refrigerant migration and eventual E1 communication faults as refrigerant charge drops below the compressor's minimum threshold. After all flare connections are made and verified with a digital torque wrench (7/8" flare: 49–54 ft-lb; 3/8" flare: 13–18 ft-lb), pull the system down to below 500 microns and hold for a minimum of 15 minutes before breaking the vacuum with refrigerant. This triple-evacuation protocol is not optional — it removes non-condensable gases that inflate system head pressure and degrade measured SEER2 in the field. Per EPA Section 608, all refrigerant handling, recovery, and system charging must be performed by an EPA 608-certified technician using certified recovery equipment.

Key Benefits

• 23 SEER2 Efficiency: Exceeds current federal minimum efficiency standards, reducing annual cooling energy costs relative to lower-rated systems in the same BTU class.
• 115V Operation: Operates on a standard 115V single-phase circuit — retrofit-friendly for rooms where a 208/230V dedicated circuit does not already exist.
• R-410A Factory Pre-Charged: The outdoor unit ships with a factory refrigerant charge, minimizing on-site charging variables when line set length is within the rated pre-charge distance.
• Ventus X Series Platform: Inverter-driven variable-speed compressor technology modulates capacity continuously to maintain setpoint temperature without the temperature swings of single-stage systems.
• 1.0-Ton / 12,000 BTU Capacity: Appropriately sized for spaces up to approximately 550 sq ft under standard load conditions (consult a Manual J load calculation for accurate sizing).
• 7-Year Compressor / 5-Year Parts Warranty: Backed by HVAC Mirage's limited warranty when installed by a licensed professional.

Technical Specifications

Compatibility & Fitment

• ✅ Compatible with dedicated 115V / 60Hz single-phase circuits.

• ✅ Wall-mounted form factor — installs on any structurally sound exterior or interior wall; does not require joist-bay framing or drop-ceiling grid.
• ❌ NOT compatible with 208/230V-only circuits.
• ❌ NOT a complete mini split system — outdoor condensing unit is NOT included.
• ❌ Line set is NOT included; 3/8" liquid × 7/8" suction copper line set must be purchased separately.
• ❌ Wall mounting bracket is NOT included.
• ❌ NOT rated for operation as a standalone cooling or heating device — requires a matched outdoor unit for function.
• ❌ NOT a DIY quick-connect kit — standard flare connections require EPA 608-certified professional installation.

Frequently Asked Questions

Is professional installation required, or is this a DIY-friendly unit?

Professional installation is required. The IMZH120C is a standard flare-connection indoor air handler, not a pre-charged DIY quick-connect kit. EPA Section 608 certification is required to handle and recover R-410A refrigerant during installation. The 7-Year Compressor / 5-Year Parts Limited Warranty is contingent on licensed professional installation.

What breaker size do I need for this system?

This indoor air handler operates on 115V / 60Hz single-phase power. The exact breaker (MCA/MOCP) specification for the complete system depends on the matched outdoor condensing unit — consult that unit's installation manual for the dedicated circuit requirement. Do not share a circuit with other loads. [NEEDS VERIFICATION — confirm MCA/MOCP with the matched outdoor unit's nameplate data.]

Is the line set included with the IMZH120C?

No. The line set is NOT included. This unit requires a 3/8-inch liquid line and a 7/8-inch suction line, purchased separately. Line set length must be sized to the matched outdoor condensing unit's specifications.

Is an outdoor condensing unit included?

No. The IMZH120C is an indoor air handler unit only. A compatible HVAC Mirage Ventus X Series outdoor condensing unit must be purchased separately and must be an AHRI-certified match to this indoor head for warranty validity and rated efficiency.

Does this system work in cold-climate low-ambient heating conditions?

[NEEDS VERIFICATION] — the published spec data does not confirm a minimum ambient heating operating temperature for the IMZH120C. Confirm the low-ambient heating rating with the matched outdoor condensing unit's specifications before specifying for cold-climate applications.

Compliance & Warranty

• Factory Warranty: 7-Year Compressor Limited Warranty / 5-Year Parts Limited Warranty. Warranty is valid only when the unit is installed by a licensed HVAC professional. DIY or self-installation voids coverage.
• EPA Section 608: All refrigerant handling, recovery, and system commissioning must be performed by an EPA 608-certified technician using certified recovery equipment. This is a federal requirement, not a manufacturer preference.
• SEER2 Compliance: Rated at 23 SEER2, meeting and exceeding current U.S. Department of Energy minimum efficiency standards for ductless mini split systems.
• Refrigerant: R-410A. Note: R-410A is subject to ongoing EPA phasedown regulations under AIM Act provisions — confirm current availability and regulatory status with your HVAC supplier at time of installation.
