HVAC Mirage | 12000 BTU | 19.0 SEER2 | Concealed Duct Ceiling | Mini Split Air Handler | 208/230V | DGFH181C

The HVAC Mirage DGFH181C is a 12,000 BTU concealed ducted indoor air handler built for discreet, high-efficiency climate control in residential and light-commercial spaces. It is designed for installers who need a clean-ceiling solution where wall-mounted or cassette units are not suitable—while delivering 19.0 SEER2 efficiency as part of a compatible multi-zone or single-zone system.

The HVAC Mirage DGFH181C belongs to the Concealed Ducted Series—engineered for installations where the air handler must disappear entirely into the ceiling cavity. Operating on 208-230V single-phase power and charged with R-454B refrigerant, this unit is strictly an indoor component: it must be paired with a compatible HVAC Mirage outdoor condenser to form a complete, operational system. At 19.0 SEER2, it meets current Department of Energy efficiency thresholds for the Northern and Southern U.S. climate regions.

Installation Requirements & Accessories

• Voltage Requirement: Dedicated 208-230V / 60Hz / Single-Phase circuit. Not compatible with 115V-only circuits.
• Line Set (NOT included): Requires a copper line set — 3/8" Liquid line and 7/8" Suction line. Purchase separately to match your run length.
• Outdoor Condenser (NOT included): This listing is for the indoor air handler only. A compatible HVAC Mirage outdoor condenser must be purchased separately.
• Mounting Hardware (NOT included): Ceiling framing, hangers, and ductwork connections are field-supplied.
• Refrigerant: R-410A, factory pre-charged. Handling requires EPA Section 608 certification.
• Professional Installation Required: Licensed HVAC technician installation is mandatory for warranty validity.

Pro-Installer Tip: When connecting the 3/8" liquid and 7/8" suction line sets to the DGFH181C, use an eccentric flaring tool to produce consistent, burr-free flare seats—undersized or ovalized flares are the leading cause of refrigerant loss and "E1" indoor/outdoor communication faults on concealed-duct systems where the evaporator coil is inaccessible post-installation. After brazing or flaring all connections, pull a vacuum below 500 microns and hold for a minimum of 15 minutes before opening the service valves—this satisfies EPA 608 Section (B) deep-vacuum requirements and confirms there are no moisture traps in the refrigerant circuit that would degrade long-term compressor efficiency. Use 14/4 AWG stranded copper control wire between the indoor and outdoor units; undersized or solid-core wire is a common source of intermittent communication codes in concealed installations where re-access is disruptive and costly.

Key Benefits

• 19.0 SEER2 efficiency rating meets current DOE minimum standards for both Northern and Southern U.S. climate regions when paired with a matched outdoor unit.
• Concealed ceiling installation delivers a clean, ductwork-style aesthetic—no exposed wall unit, no floor-space intrusion.
• R-410A factory pre-charge reduces field refrigerant handling time and simplifies commissioning for licensed installers.
• Compatible with multi-zone outdoor condensers, allowing this handler to serve as one of several zones in a larger system architecture.
• 7-Year Compressor / 5-Year Parts Limited Warranty provides long-term cost protection when installed by a licensed professional.

Frequently Asked Questions

Is professional installation required to keep the warranty valid, or is this a true DIY kit?

Professional installation is required. This is not a DIY kit. It does not include pre-charged line sets and must be installed by a licensed HVAC technician to maintain the 7-Year Compressor / 5-Year Parts Limited Warranty.

Is the line set included, and if not, what size do I need to buy?

The line set is NOT included. This unit requires a copper line set with a 3/8" Liquid line and a 7/8" Suction line. Purchase the length that matches your installation run.

What breaker size do I need for this system?

[NEEDS VERIFICATION] — The source data confirms 208-230V / 60Hz / Single-Phase power, but the specific MCA (Minimum Circuit Ampacity) and MOP (Maximum Overcurrent Protection) for the DGFH181C indoor handler are not provided in available spec data. Consult the installation manual or a licensed electrician before wiring.

Does this unit include the outdoor condenser?

No. The DGFH181C is an indoor air handler only. A compatible HVAC Mirage outdoor condenser must be purchased separately to form a complete operational system.

What refrigerant does this system use?

This unit uses R-454B refrigerant, factory pre-charged. Refrigerant handling must comply with EPA Section 608 regulations and be performed by a certified technician.

Compliance & Warranty

The HVAC Mirage DGFH181C uses R-454B refrigerant. Installation and any refrigerant handling must be performed by an EPA Section 608-certified technician in compliance with applicable federal, state, and local regulations. This unit carries a 7-Year Compressor / 5-Year Parts Limited Warranty when installed by a licensed HVAC professional; warranty coverage may be voided if installation is performed by an uncertified individual. SEER2 rating is achieved when the indoor handler is paired with a matched, AHRI-certified HVAC Mirage outdoor condenser.
