Installation Requirements & Accessories
- Voltage: Requires a dedicated 208-230V / 60Hz / 1-Phase circuit. Not compatible with 115V-only circuits.
- Breaker Size: [NEEDS VERIFICATION] — confirm with the installation manual or a licensed electrician.
- Line Set: Line set is NOT included. Purchase a separate copper line set: 3/8" liquid line x 7/8" suction line. Length is determined by your installation layout.
- Outdoor Unit: The outdoor condensing unit is NOT included with this listing. A compatible HVAC Mirage outdoor unit must be purchased separately.
- Mounting Bracket: Wall mounting bracket is NOT included — verify compatibility and source separately.
- Refrigerant Handling: Unit is factory pre-charged with R-454B. Any refrigerant work must be performed by an EPA Section 608-certified technician.
- Professional Installation Required: This is not a DIY kit. Installation by a licensed HVAC contractor is required to maintain warranty coverage.
Pro-Installer Tip
[Technical Friction] When flaring the 7/8" suction line connection at the indoor air handler, flare defects are the leading cause of refrigerant leaks at the indoor coil — a leak that manifests months later as ice buildup and loss of cooling capacity.
[Long-Term Prevention] A proper, burr-free flare prevents micro-fractures that allow R-410A to escape slowly, eventually triggering nuisance "E1" communication fault codes as the system loses refrigerant charge and the pressure sensors fall out of range.
[Expert Validation] Use an eccentric (offset) flaring tool rated for 7/8" ACR tubing, and torque the flare nut to manufacturer specification using a calibrated digital torque wrench — never tighten by feel.
[Professional Standard] Before re-pressurizing, pull a system vacuum below 500 microns (verified with a quality micron gauge held for 15 minutes minimum) to confirm zero moisture contamination, as required by EPA Section 608 best practices and necessary to protect the compressor from acid formation during operation.
Key Benefits
- 19.0 SEER2 Efficiency: Exceeds current federal minimum efficiency standards, reducing operating costs compared to conventional split systems.
- Factory Pre-Charged R-410A: Refrigerant is pre-loaded at the factory, ensuring correct charge weight and reducing field charging variables — though professional vacuum and leak-check procedures are still required.
- Wall-Mounted Form Factor: Installs high on an interior wall for even, unobstructed airflow across the conditioned zone without consuming floor space.
- 1.0 Ton / 12,000 BTU Capacity: Sized for single-zone applications — typical residential bedrooms, home offices, additions, or server rooms up to approximately 450–550 sq. ft. depending on insulation and climate zone.
- 7-Year Compressor Warranty: The 7-Year Compressor / 5-Year Parts Limited Warranty provides above-average coverage in the ductless segment when professionally installed.
- 208-230V Compatibility: Operates on the standard residential heavy-load circuit voltage, compatible with a wide range of single-family and multi-family electrical service configurations.

Frequently Asked Questions
What breaker size do I need for this system?
This unit operates on 208-230V / 60Hz / 1-Phase power. The specific breaker and wire gauge requirements are [NEEDS VERIFICATION] — consult the full installation manual or a licensed electrician before running new circuits. A dedicated circuit is required.
Is professional installation required to keep the warranty valid, or is this a true DIY kit?
This is not a DIY kit. The HVAC Mirage IGFH121C is a professional-grade indoor air handler that requires a licensed HVAC technician for installation. The 7-Year Compressor / 5-Year Parts Limited Warranty is contingent on professional installation per manufacturer requirements. EPA Section 608 certification is required to handle R-410A refrigerant.
Is the line set included, and if not, what size do I need to buy?
The line set is NOT included with this indoor air handler. You will need to purchase a separate line set sized at 3/8" liquid line and 7/8" suction line. Confirm the required length based on your installation layout before ordering.
Does this system work in cold climates (low-ambient heating)?
The operating temperature range for heating mode is [NEEDS VERIFICATION] — the source data does not confirm a rated low-ambient heating threshold for this unit. Contact HVAC Mirage or your installing contractor to confirm cold-climate suitability before purchase if low-ambient operation is a requirement.
Is this an indoor-only unit, or does it include the outdoor condenser?
This listing is for the indoor air handler unit only (model IGFH121C). The outdoor condenser is NOT included. A compatible HVAC Mirage outdoor condensing unit must be purchased separately to form a complete single-zone mini split system.
Compliance & Warranty
Warranty: The HVAC Mirage IGFH121C carries a 7-Year Compressor / 5-Year Parts Limited Warranty, contingent on professional installation by a licensed HVAC contractor. DIY installation or installation by an uncertified technician may void coverage — verify warranty terms with HVAC Mirage before proceeding.
Refrigerant Compliance: This unit contains R-410A refrigerant. Purchase, handling, and recovery of R-410A requires EPA Section 608 certification. Technicians must recover refrigerant during service rather than venting to the atmosphere.
Efficiency Standards: Rated at 19.0 SEER2, this unit meets current U.S. Department of Energy regional efficiency standards applicable to residential split systems. Verify regional applicability with your contractor.
