About This Product

Experience relief the moment you enter your room with TCL's high-wall 12,000 BTU ductless mini split heat pump. Designed for residential applications, this affordable HVAC solution delivers powerful performance without compromising premium features. When paired with the available matching outdoor unit, the system will provide an impressive 23 SEER2 energy efficiency rating, helping reduce monthly utility bills while maintaining optimal climate control. A dual-swing louver system ensures both horizontal and vertical sweeping air throw, to perfectly reach all directions of the room. Paired with the matching outdoor unit, this system offers low ambient heating performance-even in extreme temperatures down to -13°F-thanks to its efficient 9.8 HSPF2 heating rating. Operating as quietly as 29 dB, this ultra-quiet ductless system ensures restful nights, comparable to the sound level of a library. Easily control the system from anywhere with the TCL Home App. Pair with the available matching outdoor unit which comes pre-packed with a full 16 ft. line set, so your ductless mini split heat pump system is ready to be up and running in a single afternoon. 5-Year Parts and Compressor Warranty / 10- Year Warranty with Pro Installation

Highlights

  • Certified cooling performance: 12000 BTU/hour capacity, high efficiency 23 SEER2, 12 EER2
  • Certified heating performance: 12000 BTU/hour capacity, high efficiency 9.8 HSPF2
  • Built-in WIFI: Smart out of the box - Easily control your system via the TCL Home App, Amazon Alexa, or Google Assistant. Now you can take control of your air conditioning hands-free or even remotely.
  • Voltage: 230-Volt, 60Hz, 1Ph
  • Energy star and energy star cold climate certified
  • 4-way airflow - provides up to 72 angles of air supply for a precise and a more comfortable environment in a wide indoor space
  • ECO Mode - When compared to normal modes, ECO Mode uses less compressor capacity, which uses less energy. You may conserve energy at any time or use it to cool more effectively when it's not too hot outside.
  • Turbo Mode - delivers rapid cooling or heating for immediate comfort by boosting the air conditioner's performance to quickly reach the desired temperature. This setting maximizes cooling or heating output for a short period, making it ideal for rapidly cooling a hot room or warming a cold space. While this mode provides immediate comfort, it consumes more energy, so it's best used sparingly. Once the room reaches the desired temperature, switching back to a regular mode can help maintain comfort while conserving energy.
  • Sleep Mode - Adjusts the temperature and fan speed to provide a more comfortable sleeping environment, gradually changing the temperature setting to avoid excessive cooling or heating during the night, promoting better sleep and energy savings. The fan operates at a lower speed to minimize noise, creating a quiet and restful atmosphere. Sleep mode can also help reduce energy consumption by preventing the air conditioner from running at full capacity throughout the night.
  • iFeel Mode - maintains the set temperature wherever the remote controller is located, through a built-in temperature sensor in the remote control, allowing for more precise temperature control.
  • Runs Clean and Efficient with Effortless 4-Step Indoor Self-Cleaning cycle that freezes, defrosts, dries and heats the system to over 130°F to help sanitize and remove dust, dirt and impurities.
  • Gentle Breeze Technology uses micro‑holes to create soft, dispersed airflow and reduce cold drafts.
  • Fan mode - circulates air within the room without altering the temperature, this mode is useful for ventilating the space and maintaining air movement, especially during mild weather when cooling or heating isn't necessary, the fan speed can often be adjusted to low, medium, or high settings depending on your preference, using fan mode can help distribute conditioned air more evenly and improve overall air quality

Questions & Answers

Looking to cool my garage during typical 112 degree Arizona heat. Will a 120-volt unit be sufficient, or do I need a 230-volt system?
ByOct 14, 2026
1 Answer | 
Answer This Question

Cooling a space for a specific temperature and area depends on factors such as the garage's size, insulation, and heat load. We recommend consulting a certified HVAC professional to determine whether this unit's cooling capacity is sufficient for your space. Hope this helps! Thank you, TCL Customer Support

    What size breaker this runs on?

    Answer This Question

    The TH12SVH23BW is designed for 110-120V, 60Hz, single-phase power and has a rated current of 8.0 amps. It should be installed on a dedicated 20-amp circuit using 12 AWG wiring to help ensure safe and reliable operation. As with any hardwired appliance, we recommend having a licensed electrician verify the installation requirements and ensure compliance with local electrical codes. Thank you, TCL Customer Support

            Does DIY installation void warranty?
            BySep 15, 2026
            1 Answer | 
            Answer This Question

            DIY installation does not automatically void the warranty. However, any damage, performance issues, or component failures resulting from improper installation are not covered under the manufacturer's warranty. A critical part of the installation process is pulling a proper vacuum on the line set and indoor coil. This step removes air, moisture, and other non-condensable gases from the refrigeration system. The compressor is designed to compress refrigerant vapor only and is not intended to operate in a system contaminated with air or moisture. Moisture left in the system can also react with the compressor oil, causing it to become acidic. If a proper vacuum is not performed before startup, this acid formation can lead to premature compressor failure and damage other critical components, including Electronic Expansion Valves (EEVs), Thermostatic Expansion Valves (TXVs), filter driers, and other internal refrigeration system components. In addition, intentionally venting refrigerant into the atmosphere is prohibited under EPA regulations. Failure to follow proper installation and refrigerant handling procedures may negatively affect system performance, energy efficiency, reliability, and warranty coverage. For safety, regulatory compliance, and optimal system operation, TCL strongly recommends that all installation, commissioning, and service work be performed by a licensed and certified HVAC technician. Thank you, TCL Customer Support

              looking to purchase a 230v unit. do i need a HVAC technician to come and pull vacuum to install? Or does this come preloaded and ready to connect and start cooling immediately??
              BySep 12, 2026
              1 Answer | 
              Answer This Question

              The TH12SVH23XW condenser or outdoor unit comes factory pre-charged with refrigerant. However, the refrigerant lines and evaporator still need to be properly vacuumed before the service valves are opened and the system is started. A vacuum pump and the appropriate HVAC tools are required for this process. We recommend having the system installed by a certified HVAC technician to help ensure proper installation, safety, and performance. Thank you, TCL Customer Support

                Is there a ducted option? Or concealed option like in the ceiling for a different zone
                BySep 10, 2026
                1 Answer | 
                Answer This Question

                The TH36SEH19XW does not currently offer ducted or concealed ceiling-mounted systems. If a concealed installation is required, a ducted-style system would be needed instead. Thank you, TCL Customer Support

                  powerful and quiet!
                  Wow! I couldn't believe how easy this product was to install. It only took our pro a couple hours! It immediately made a difference in our bonus room and helped us out during this heat wave! I turned on the heat briefly to verify it works, and it transitioned from cold to heat easily. It will definitely come in handy this winter. The app is easy to use and nice to be able to change the temperature without having to find a remote. It's very quiet as well!

                  Quiet, efficient and effective
                  This TCL mini split AC and heat unit is perfect for our space. We will be using this mostly for AC but the heating is a huge bonus. I love how you can control it with a remote or an app on your phone. I also love that it’s quiet, is programmable so you can set it up to your schedule, has a gentle and turbo mode and has a self cleaner! It has everything you need, however it wasn’t super simple to install. You need a professional so you’ll have to take that into account. Luckily, my husband is a professional and was able to install it himself. Overall, highly recommend this for the simple look, and features of this split unit!

                  Easy compact cooling and heating unit.
                  This mini-split unit was very easy for a professional we hired to install, only took a few hours. Once we turned it on it was immediately operational and provided cooling air into our garage. It connected to our wifi and it is quite convenient to have the app on my phone and turn it on from anywhere I am so it can cool or heat before I get home. The remote is convenient and the display of the temperature on the actual unit itself is bright and easy to read. It cooled our garage quickly and I'm looking forward to being able to work on things during the next heat wave as well as the cold of winter. The unit itself is sleek on the wall and the fan outside is also nice and compact and not an eyesore.

The installation was quick and simple when it is done as indicated by the manufacturer, the heating function works very well and allows to maintain a pleasant temperature on cold days, in conclusion it is a very good option

                  Runs quietly and makes any area more comfortable.
                  I received this TCL Ready to Install 18,000 BTU 22 SEER2 Wi-Fi Ductless Mini Split Year Round AC and Heat Pump w/ 16 ft. Lines 230V System in exchange for my honest review. (NOTE : electrical work and professional install may be required.) This mini split arrived with everything needed right out of the box. I did need to schedule appointments for the electrical work and the professional install. My husband spends a lot of time tinkering around in our three bay garage. He usually runs several fans in the summer and a couple of large space heaters in the winter which isn’t the most energy efficient. We expect this system to cut down on heating and cooling costs but it’s too early to tell. What I can tell you is this : the unit is very quiet, has built in WiFi so you can control the unit from the TCL Home App, Amazon Alexa, or Google Assistant. It is Energy Star Certified. There is a remote control you can use to set and maintain the temperature. There is a 4 step self-cleaning cycle to help sanitize and remove dust, dirt, and impurities. Also you can just run it as a fan to circulate the air. My husband is definitely happy with the new mini split to help keep him more comfortable while working on his projects no matter what season it is.

                  Perfect for a basic garage exercise space!
                  This TCL mini split was the perfect addition for my garage to make the temps bearable in both winter and summer, as I gave my home gym set up in the garage now. The install was pretty easy, overall, although I did purchase some additional items (line covers and mounting rack) to make it perfect for my situation. One piece of feedback on the install... The instructions say to connect the line set to the "stub" from the inside unit and to push the entire set through the wall. There was no need to connect that long line set - there was plenty of extra length from the "stub" to go through the wall... No need to fight that long line set too! Just wait to connect it until after you have the inside mounted. The unit runs perfectly and has made exercising in the garage much more bearable during this hour Texas summer. I still need to add a bit of insulation in some of the exterior walls, to make it even better, but I'm very happy and satisfied with the performance this far.
