HVAC Mirage | 12,000 BTU | 21 SEER2 | Wall Mounted | Single-Zone Mini Split System | 115V | IPWH120C

The HVAC Mirage Polaris Cold-Climate Series IPWH120C is a 12,000 BTU wall-mounted indoor air handler designed for homeowners and contractors who need a high-efficiency, 115V-compatible mini split solution for single-zone residential or light-commercial spaces. This listing is for the indoor air handler unit only — a compatible outdoor condenser unit must be purchased separately.

HVAC Mirage Polaris Cold-Climate Series — 12,000 BTU Wall-Mounted Indoor Air Handler

The IPWH120C delivers 12,000 BTU (1.0 Ton) of cooling capacity at a 21 SEER2 efficiency rating, purpose-built for single-zone residential and light-commercial applications where a standard 115V outlet circuit is the only available power source. Its wall-mount form factor is the most versatile indoor unit architecture for mini split installations, requiring no drop ceiling or structural joist modification. As part of the Polaris Cold-Climate Series, this handler is matched with outdoor condensers rated for extended low-ambient operation. This listing covers the indoor air handler only; the matched outdoor condenser must be ordered and installed separately.

What's Included

Installation Requirements & Accessories

• Voltage: Dedicated 115V / 60Hz / Single-Phase circuit required. Not compatible with 208/230V-only circuits.
• Line Set (NOT included): Requires 3/8" liquid line x 7/8" suction line. Purchase separately based on the run distance to the outdoor condenser.
• Outdoor Condenser (NOT included): A compatible HVAC Mirage Polaris Series outdoor condenser unit must be purchased and installed separately.
• Mounting Bracket (NOT included): Wall mounting bracket must be sourced separately or confirmed with installer.
• Condensate Drain Line (NOT included): Gravity or pump-assisted condensate drainage must be planned for the installation site.
• Professional Installation Required: EPA Section 608 certified technician must handle refrigerant (R-454B is an A2L mildly flammable refrigerant). DIY installation voids the manufacturer warranty.
• Refrigerant: R-454B (Low-GWP, 2026 EPA AIM Act compliant). Do not substitute refrigerant types.

⚙️ Pro-Installer Tip

[Technical Friction] When flaring the 3/8" liquid line on R-454B systems, standard flaring tools calibrated for R-410A may produce a seat angle or surface finish that causes micro-leaks under the higher operating pressures of A2L refrigerants. A single compromised flare on an R-454B system will result in refrigerant migration and eventual "E1" or "Communication Error" fault codes as the system pressure drops below the compressor's operating threshold.

[Long-Term Prevention] Use an eccentric (off-center) flaring tool designed for copper-ACR tubing to produce a consistent, concentric seat face. After flaring, inspect the seat visually under a torch light for radial scoring before torquing. A flawless flare face eliminates the refrigerant loss pathway that causes nuisance fault codes and compressor short-cycling.

[Expert Validation] Torque the 3/8" liquid line flare nut to the manufacturer's published specification using a calibrated digital torque wrench — do not rely on feel. If the installation manual does not specify a value, the industry standard for 3/8" ACR flares is approximately 30–33 ft-lbs. Verify actual torque spec in the IPWH120C installation manual.

[Professional Standard] R-454B is an A2L mildly flammable refrigerant. EPA Section 608 certification is federally required for purchase and handling. After the system is charged, use a listed A2L refrigerant leak detector at all flare connections, the service valve stems, and the Schrader ports before powering the system. A confirmed leak-free installation is both an EPA mandate and the baseline requirement for the 7-Year Compressor Warranty to remain valid.

Key Benefits

• 21 SEER2 Efficiency: Exceeds the 2023 DOE minimum SEER2 standards for the North region, reducing operating costs compared to lower-efficiency single-stage systems.
• 115V Circuit Compatibility: Installs on a standard 115V single-phase circuit — a critical advantage for retrofit applications where 208/230V service is not available at the installation location.
• R-454B Refrigerant: Fully compliant with the 2026 EPA AIM Act phase-down schedule, protecting your investment against future regulatory re-work costs.
• Cold-Climate Series Rating: Polaris Series outdoor condensers are rated for low-ambient heating operation — verify the matched condenser's minimum operating temperature for your climate zone.
• Wall-Mount Architecture: No structural ceiling modification required. Compatible with standard interior wall installations. Slim profile minimizes room footprint.
• 7-Year Compressor Warranty: Industry-leading coverage when installed by a licensed professional, providing long-term protection on the highest-cost system component.

Frequently Asked Questions

What breaker size do I need for the HVAC Mirage IPWH120C?

This unit operates on a dedicated 115V / 60Hz / single-phase circuit. The exact dedicated breaker amperage requirement is [NEEDS VERIFICATION] — consult the full installation manual and a licensed electrician before wiring. This unit must not be installed on a shared circuit.

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

Professional installation by an EPA Section 608-certified HVAC technician is required. This is not a pre-charged DIY kit. The system uses R-454B, an A2L mildly flammable refrigerant that requires proper vacuuming, flaring, and refrigerant charging by a licensed technician. Performing DIY installation will void the 7-Year Compressor / 5-Year Parts Limited Warranty.

Is the line set included with this unit?

No. The refrigerant line set is NOT included. You must purchase a 3/8" liquid line x 7/8" suction line set separately, sized to the actual run distance between the indoor air handler and the outdoor condenser. The outdoor condenser unit is also sold separately.

Does the HVAC Mirage Polaris Series work in cold climates with low-ambient heating?

This unit is part of the Polaris Cold-Climate Series, which is engineered for low-ambient heating performance. The specific minimum outdoor operating temperature rating for the heating mode is [NEEDS VERIFICATION] — confirm the matched outdoor condenser unit's cold-climate specifications before purchasing for extreme cold-weather applications.

What refrigerant does this system use, and is it compliant with current EPA regulations?

This unit uses R-454B, a low global warming potential (GWP) refrigerant fully compliant with the 2026 EPA AIM Act phase-down schedule. R-454B is classified as an A2L mildly flammable refrigerant — all installation work must comply with ASHRAE 15 safety standards and applicable local fire codes. An EPA Section 608 certified technician is required for all refrigerant handling.

Compliance & Warranty

• Compressor Warranty: 7 Years (Limited) — Valid only with installation performed by a licensed HVAC professional. DIY or uncertified installation voids this coverage.
• Parts Warranty: 5 Years (Limited) — Same professional installation requirement applies.
• Refrigerant Compliance: R-454B is 2026 EPA AIM Act compliant. Handling requires an EPA Section 608 certified technician as mandated by federal law.
• Energy Efficiency: 21 SEER2 rating meets or exceeds DOE regional efficiency minimums effective January 1, 2023.
• Warranty Registration: [NEEDS VERIFICATION — confirm whether product registration is required within a defined window to activate full warranty coverage].
