This is a ducted heat pump system for whole-house or multi-room central air, built for homeowners who want central-air comfort without exposed wall units. It heats and cools using one outdoor condenser paired with a concealed indoor air handler that connects to your home's ductwork.
The Air-Con Neptune Series pairs an inverter-driven outdoor condenser with a concealed ducted air handler designed to sit above a ceiling and distribute conditioned air through connected ductwork rather than through an exposed indoor head. Air-Con publishes AHRI-certified performance data for matched indoor/outdoor combinations under this series. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
System Components
- Outdoor Condenser Unit: Inverter-driven heat pump condenser, R32 refrigerant, side-discharge design
- Indoor Air Handler: Concealed ducted unit connecting to home ductwork (not a wall-mounted or cassette head)
- Available capacities: 24000 BTU, 30000 BTU, 36000 BTU, 48000 BTU, 60000 BTU (see Options & SKUs table below)
Installation Requirements & Accessories
- Voltage: [NEEDS VERIFICATION] — not specified in source data; confirm 208/230V vs. 115V compatibility with your installer before purchase
- Line set size: [NEEDS VERIFICATION] — not specified in source data by capacity
- Line Set Sold Separately — not included with this system
- Not compatible with 115V-only circuits unless explicitly confirmed for your specific capacity variant [NEEDS VERIFICATION]
- Not a listed match for indoor/outdoor model combinations outside the paired SKUs shown in the Options & SKUs table
- Wall sleeve/mounting bracket not applicable to this ducted configuration; ductwork design and installation is the responsibility of the installing contractor
Pro-Installer Tip
Flare connections on ducted systems are a common source of slow refrigerant leaks, especially at the larger line diameters used on 48000 and 60000 BTU condensers. Under-torqued or over-torqued flares lead to gradual charge loss, reduced capacity, and eventual compressor strain. Torque each flare nut to the manufacturer's specified value using a digital torque wrench, and pull the system down below 500 microns with a calibrated vacuum gauge before opening the service valves — a rushed vacuum is the single most common cause of moisture-related compressor failure in the field. This work must be performed by an EPA Section 608-certified technician, both to comply with federal refrigerant handling law and to protect the system's rated efficiency over its service life.
Key Benefits
- Inverter-driven compressor for variable-speed heating and cooling rather than fixed on/off cycling
- Heat pump operation covers both heating and cooling from one outdoor unit
- R32 refrigerant, a lower-GWP option compared to older refrigerant blends
- Space-saving side discharge condenser design for tighter outdoor placement
- Flexible condenser settings for site-specific configuration
- Concealed ducted indoor unit keeps equipment out of sight, distributing air through ductwork

Compatibility & Fitment
- Each capacity is sold as a matched outdoor/indoor SKU pair, as listed in the Options & SKUs table above — do not mix outdoor and indoor units across different capacity pairs.
- This is a concealed ducted air handler, not a wall-mounted head, cassette, or floor unit — it requires ductwork design and installation.
- Not compatible with indoor or outdoor units outside the specific paired model numbers shown above.
- Line set is not included with any capacity in this lineup and must be purchased separately, sized to your installer's specification.
- Voltage compatibility is not specified in the source data for this listing — confirm with your installer before ordering [NEEDS VERIFICATION].
FAQ
What breaker size do I need for this system?
[NEEDS VERIFICATION] Breaker size was not provided in the manufacturer specifications supplied for this listing. Refer to the unit's nameplate or the manufacturer's installation manual before wiring.
Is professional installation required to keep the warranty valid, or is this a true DIY kit?
This is not a DIY pre-charged kit. Installation by a licensed HVAC professional is required to maintain the manufacturer warranty.
Is the line set included, and if not, what size do I need to buy?
The line set is not included. [NEEDS VERIFICATION] Exact line set sizing per BTU capacity was not provided in the source data — confirm sizing with your installer against the outdoor and indoor model numbers.
Does this system work in cold climates (low-ambient heating)?
This is a heat pump system, meaning it provides both heating and cooling. [NEEDS VERIFICATION] Specific low-ambient operating temperature ranges were not provided in the source data.
Compliance & Warranty
Installation by a licensed HVAC professional is required to maintain warranty. Refrigerant handling on this system must be performed by an EPA Section 608-certified technician. [NEEDS VERIFICATION] — Specific warranty term length and coverage details were not included in the source data; refer to the "Resources (System Manuals and Warranty)" Tab above for the full manufacturer warranty document.
