  • Key Specs
    • Recommended Room Size: 750 square feet (The recommended area size in which the product is designed to operate and produce optimal results, such as the desired heating or cooling. Generally, running a unit too big or too small for the space will result in ineffective operation and wasted energy.)
    • BTU Cooling Rating: 12000 british thermal units (The amount of BTUs (British Thermal Units) per hour the unit uses to cool the air, also known as cooling capacity. For best results, the capacity of the unit should be based on the size of the area it is intended to cool. For example, a 5,000 BTU capacity works optimally for a 150 square foot room. In general, an oversized unit will not effectively remove humidity, and an undersized unit will not cool the space efficiently.)
    • Number of Cool Settings: 4
    • Number of Fan Speeds: 3
    • Airflow Rate: 353 cubic feet per minute
    • Remote Control: true
    • Integrated Heater: true
    • Sleep Mode: true (Enabling this mode sets the unit to first reach the desired temperature, then gradually increase the temperature over a period of time until it reaches a new set temperature, typically several degrees higher than the initial cool setting. This mode helps save energy while keeping the room comfortable.)
    • Timer: true
    • Auto Shut-Off: true (Feature automatically turns off the product.)
    • Energy Efficiency Ratio: 10 (The ratio of output BTUs (British Thermal Units) to input electrical energy (watts) at a given operating point. Generally, the higher the number, the more efficient the unit. Though higher efficiency units are typically more expensive upfront, they may offset the price in energy costs over time.)
    • Seasonal Energy Efficiency Ratio (SEER): 20 (This rating is generally used to measure a central air conditioner's and mini-split air conditioner's energy efficiency and will not be found on window or room air conditioners. SEER measures the ratio of output BTUs (British Thermal Units) to input electrical energy (watts) over the course of an entire cooling season. Generally, the higher the SEER rating, the more energy efficient the equipment is.)

    The Fantastic Mini Split!! ( > ᴥ <)

    “I was looking for an affordable mini split to cool and heat my bedroom, and this Costway unit has been a great choice. The installation took some time but was pretty straightforward with some basic DIY skills — just make sure to follow the instructions carefully. Once installed, it worked perfectly right away. It cools the room down really fast and keeps it comfortable even on really hot days. The heat pump feature is a bonus for chilly nights, so I love having both options in one unit. It runs very quietly, and the remote control makes it super easy to adjust settings from bed. Plus, the modern white design looks nice and clean on the wall. For the price, you can’t beat it — it does exactly what it promises without breaking the bank. I definitely recommend it if you want reliable cooling and heating without spending a fortune!”

    The Hot and Cold of Costway

    Review: Costway 12,000 BTU Mini Split AC with Heat Pump I’ve been using the Costway 12,000 BTU mini split system for a while now, and overall it’s a solid unit for the price. It offers both cooling and heating, which makes it a versatile year-round option. Performance: The cooling is quick and effective—within minutes, it noticeably drops the room temperature. At 12,000 BTU, it’s well-suited for medium-sized rooms, offices, or small apartments (around 400–550 sq. ft.). The heating function also performs reliably, producing steady warmth without feeling weak or uneven. Efficiency & Noise: This unit runs quietly compared to window ACs, which is great if you’re using it in a bedroom or living space. The energy efficiency is decent—definitely a money-saver over time compared to portable units, though not quite as advanced as some premium models. Installation: Installation can be a bit challenging if you’re not handy. The instructions are clear, but like most mini splits, you’ll need the right tools and some patience. Professional installation is recommended if you don’t have prior experience. Once set up, though, the unit is very low-maintenance. Features: The remote control is intuitive, and the different modes (cool, heat, dehumidify, fan) give flexibility for different weather conditions. The timer and sleep functions are nice touches. Pros: Strong cooling and heating for the size Quiet operation Multiple modes (cool, heat, fan, dehumidify) Good value compared to name-brand alternatives Cons: Installation can be tricky without experience Slightly bulkier design than some higher-end models Efficiency is good, but not top-tier Verdict: If you’re looking for an affordable mini split with both AC and heat, the Costway 12,000 BTU unit delivers great performance for the cost. It won’t match the premium feel or ultra-high efficiency of bigger brands like Mitsubishi or Daikin, but it’s reliable, versatile, and budget-friendly.
