This is a single-zone ductless mini split system for cooling and heating one room without ductwork. It's built for homeowners adding comfort to a bedroom, addition, or living space that central air doesn't reach.
The Air-Con Serene Series pairs a wall-mounted indoor unit with a matched outdoor condenser for single-room heating and cooling. This 12,000 BTU, 16 SEER configuration combines outdoor unit model ASRCI4H4S12 with indoor unit model ASREM4H4S12 — an AHRI-certified match per Air-Con's published multi-split ODU/IDU tables. Both units carry Energy Star certification. 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 — Model ASRCI4H4S12 (12,000 BTU, 16 SEER, 208-230V)
- Indoor Wall-Mounted Unit — Model ASREM4H4S12 (matched to outdoor unit ASRCI4H4S12)
Installation Requirements & Accessories
- Voltage: 208-230V — not compatible with 115V-only circuits.
- Includes a 15ft line set and wiring per this listing's title; exact line set diameter is [NEEDS VERIFICATION] — confirm against the installation manual before purchase of any additional line set materials.
- Line set sold separately warning does not apply as written to this listing — a 15ft line set is included per the product title, but you should confirm length and diameter are sufficient for your install distance before ordering.
- Not compatible with 115V-only circuits.
- Not a listed match for other Air-Con Serene Series capacities (9,000 / 18,000 / 24,000 BTU indoor or outdoor units) — those use different model numbers (e.g., ASRCI4H4S09, ASRCI4H4S18, ASRCI4H4S24) and are not interchangeable with the 12,000 BTU units in this listing.
- Wall mounting bracket inclusion is [NEEDS VERIFICATION].
Pro-Installer Tip
Flare connections on 208-230V systems like this one are a common source of long-term refrigerant loss if the flare nut isn't torqued to spec — over-tightening cracks the flare face, under-tightening leaves a slow leak that shows up months later as reduced capacity or an "E1" communication fault. Always verify flare torque with a digital torque wrench rather than "feel," and pull the system down below 500 microns with a calibrated vacuum gauge before opening the service valves. This isn't optional: EPA Section 608 certification is required to handle refrigerant on this system, and a proper deep vacuum is what keeps the 16 SEER efficiency rating intact over the life of the unit.

FAQ
What breaker size do I need for this system?
Breaker size is [NEEDS VERIFICATION]. This system runs on a 208-230V circuit; confirm exact breaker/amperage requirements against the manufacturer's installation manual before rough-in.
Is professional installation required to keep the warranty valid, or is this a true DIY kit?
This is a standard flare-connection system, not a pre-charged DIY kit. Installation by a licensed HVAC professional is required to maintain the warranty.
Is the line set included, and if not, what size do I need to buy?
This listing includes a 15ft line set and wiring per the product title. Exact line set diameter (liquid/suction line sizes) is [NEEDS VERIFICATION] — confirm against the installation manual for ASRCI4H4S12/ASREM4H4S12.
Does this system work in cold climates (low-ambient heating)?
Low-ambient heating performance and minimum operating temperature are [NEEDS VERIFICATION]. This unit is a heat pump model capable of both heating and cooling per the manufacturer overview, but published operating temperature ranges were not provided in source specs.
Compliance & Warranty
Installation by a licensed HVAC professional is required to maintain warranty. This system uses standard flare fittings and requires EPA Section 608 certified handling of refrigerant during installation and service.
