● Powerful and Efficient Heating for Winter: Designed with an advanced heat pump system, this ductless air conditioner provides rapid and consistent warmth, effectively heating spaces up to 1250 sq. ft. even in colder weather. The 4D auto swing feature ensures wide and even distribution of warm air throughout the room, eliminating cold spots and creating a uniformly comfortable environment.
● Advanced Inverter Technology for Consistent Warmth: The cutting-edge inverter technology intelligently adjusts the compressor speed to maintain your desired temperature with minimal fluctuation. This not only ensures steady comfort but also significantly reduces energy consumption, helping you save on winter electricity bills. Choose the ECO mode​​ for optimized energy use during extended operation.
● Quiet Operation for Undisturbed Comfort: Experience peace and quiet with noise levels as low as 47 dB on the lowest setting. The Sleep mode automatically adjusts the temperature and fan speed for a tranquil night's rest, ensuring the warmth never disturbs your sleep.
● Self-Cleaning for Healthier Air: Maintain optimal air quality effortlessly. The high-temperature self-cleaning function (57℃) automatically removes mold, dust, and bacteria from the internal evaporator. This reduces odors and minimizes manual maintenance, promoting a healthier indoor environment during the winter months when ventilation is often reduced.
● Package and Installation: This mini split heat pump comes as a complete package, including an indoor unit, an outdoor unit (pre-charged with eco-friendly R32 refrigerant), a remote control, and a comprehensive installation kit. For optimal performance and safety, we recommend installation by a certified professional.

    Costway 12000 BTU Mini Split AC, 20 SEER2 Ductless Air Conditioner w/Pre-Charged Condenser, 115V Energy Saving AC w/Heat Pump DC Inverter System & Installation Kit

    10/03/2025

    Absolute garbage. It runs our 32 refrigerant, which is absolutely impossible to either buy or get a technician to work on.;With the money I’ve spent on trying to get the refrigerant for this unit, it would’ve been cheaper to throw this thing in the garbage and buy a complete new one.;Additionally, the brand name on the one I got is Cost Way, so just some random unit that was substituted for the one I actually ordered.;Unfortunately for me, I bought it during prime days and stored it for four months before I installed it so I’m stuck with it.

    A:
    The unit is pre-charged with refrigerant, and if you need to refill it, the required amount is typically marked on the outdoor unit's nameplate. If you have a leak, it's important to locate and repair it before refilling the refrigerant, which should be done by a qualified professional.

  • Q:
    When hooking up is this u it 110v hookup or 220v hookup? Which would be recommended? Thank you!
    A:
    It operates on 220V. It is recommended to connect it to a 220V power supply for optimal performance. Please ensure that you have the appropriate electrical setup for this unit, as it cannot be connected to a 110V outlet[694ce6458bc1079b6727c53](CITE).
  • Q:
    Hello, its winter here in Chicago. If I put my remote on Auto mode will it shut off when hits the factory heat temp of 68 degrees. Or will continue to run all day. I'm thinking when the system sees the room hits the target 68 degrees it shutsu off. Than turns back on once it goes under 68 degrees. Is this accurate? Thanks
    A:
    In Auto mode, the system will not completely shut off when it reaches the factory heat temperature of 68 degrees. Instead, it will continue to operate at a lower power to maintain the temperature.
    Costway representative
  • Q:
    I see the remote has an electric heat button. Does this head unit in fact have electric heating elements?
    A:
    The product is heated by a heat pump, not electrically.
    Costway representative
  • Q:
    Is this unit pre charged
    A:
    Yes, the unit is pre-charged with refrigerant for standard installation.
    Costway representative
  • Q:
