Some units provide higher SEER2 ratings for greater energy efficiency, while others offer different BTU outputs for larger or smaller spaces. You might also prefer a different smart control interface or a more compact indoor unit. By focusing on hard data like voltage, coverage area, and connectivity, this list helps you find a mini split that fits your exact needs without compromise.
Our top pick: Rellytech 18k BTU 21 SEER2 Mini Split.
Comparing Alternatives to the TCL 14
YITAHOME 12000 BTU 230V Mini Split
The YITAHOME 12000 BTU unit offers a smaller footprint and lower cooling capacity than the Rellytech 18k model. It covers less area, making it suitable for smaller rooms rather than large spaces. The efficiency rating is 17 SEER2, which is lower than the Rellytech’s 21 SEER2, meaning it uses more energy for the same cooling output. Both units run on 230V and include Wi-Fi smart control. You should choose this option if your space is under 500 square feet and you prioritize a lower initial cost over maximum energy efficiency. The indoor unit is also slightly taller at 11.5 inches compared to the Rellytech’s 9.5 inches. This model fits budget-conscious buyers who do not need the highest efficiency rating.
ROVSUN 12000 BTU 230V Mini Split
The ROVSUN 12000 BTU model provides a middle ground between the smaller YITAHOME and the larger Rellytech. It shares the 230V voltage requirement but delivers less cooling power than the Rellytech’s 18,000 BTU. Its efficiency is 20 SEER2, which is close to the Rellytech’s 21 SEER2, offering nearly comparable energy savings. Both units feature Wi-Fi connectivity for smart control. The ROVSUN indoor unit is 11.5 inches tall, while the Rellytech is 9.5 inches. This alternative is ideal for medium-sized rooms where 12,000 BTU is sufficient. You get high efficiency without the higher capacity of the 18k model. It is a solid choice if you want near-top-tier efficiency with a moderate cooling load.
COSTWAY Blast Pro 18000 BTU 230V
The COSTWAY Blast Pro matches the Rellytech in cooling capacity with 18,000 BTU and shares the 230V electrical requirement. However, its efficiency is 20 SEER2, which is slightly lower than the Rellytech’s 21 SEER2. Both units support Wi-Fi smart control. The COSTWAY indoor unit is 12 inches tall, making it taller than the Rellytech’s 9.5-inch design. This model is best for users who need strong cooling for large rooms but find the Rellytech’s higher efficiency rating unnecessary. The 208/230V support ensures compatibility with standard residential wiring. You should pick this if you prefer a slightly different form factor or brand, as the core performance specs are very similar to the Rellytech, with a minor trade-off in efficiency.
Mountman 12000 BTU 19 SEER2 Mini Split
The Mountman 12000 BTU unit is smaller in capacity than the Rellytech 18k model, covering up to 750 square feet as listed in its attributes. It runs on 230V and includes Wi-Fi smart control. The efficiency rating is 19 SEER2, which is lower than the Rellytech’s 21 SEER2. The indoor unit is 11.9 inches tall, compared to the Rellytech’s 9.5 inches. This model is suitable for medium-sized rooms where 12,000 BTU is adequate. You should choose this if you want smart connectivity and 230V support but do not need the highest efficiency or maximum cooling power. It is a practical option for standard residential setups where the Rellytech’s higher capacity is overkill.
Della Vario 24K BTU 21 SEER2
The Della Vario 24K BTU model offers significantly more cooling power than the Rellytech 18k, making it suitable for larger spaces. It shares the 230V voltage and 21 SEER2 efficiency rating, meaning energy usage per BTU is comparable. Both units feature Wi-Fi, but the Della also supports Alexa voice control, adding an extra layer of smart integration. The indoor unit is much larger at 14.2 inches tall and 46.9 inches wide. This alternative is best for large rooms or open areas where 18,000 BTU is insufficient. You should pick this if you need maximum cooling capacity and value voice control compatibility. It is a professional-grade option for those who prioritize raw power and advanced smart features over a compact indoor design.

Frequently asked questions
Which tcl 14 alternative offers the highest efficiency rating?
The Rellytech 18k BTU and the Della Vario 24K BTU both lead with a 21 SEER2 rating. This metric indicates how efficiently the unit converts electricity into cooling. Higher SEER2 values generally mean lower energy consumption for the same amount of cooling power delivered to your space.
Do these alternatives support 230V electrical circuits?
Yes, all six listed mini splits operate on 230V power. This includes the Rellytech, YITAHOME, ROVSUN, COSTWAY, Mountman, and Della models. This voltage requirement is common for larger capacity units and may differ from standard 110V household outlets used for smaller appliances.
Which model is best for smart home integration with Alexa?
The Della Vario 24K BTU is the only unit explicitly listed with Alexa smart control capabilities. It also supports Wi-Fi connectivity. This allows you to manage the unit through voice commands or a mobile app if your router is nearby.
What is the smallest indoor unit size available?
The YITAHOME 12000 BTU model has the most compact dimensions. It measures 31.2 inches wide, 11.5 inches high, and 7.9 inches long. Its lightweight design at 21.1 pounds makes it easier to mount in tighter spaces compared to the larger 18k or 24k units.
Are there options for very large rooms needing more than 18k BTU?
The Della Vario 24K BTU provides the highest cooling capacity on this list. It is designed for larger spaces that require more robust airflow and temperature control. The Rellytech and COSTWAY models offer 18k BTU, which suits medium-to-large rooms but falls short of the Della's output.
Which unit is best for budget-conscious shoppers?
The YITAHOME 12000 BTU is tagged as the best budget option. It offers a 17 SEER2 efficiency rating and Wi-Fi control at a lower cooling capacity than premium models. This makes it a practical choice for smaller rooms where peak efficiency is less critical than initial cost.
Do all these mini splits include Wi-Fi connectivity?
Yes, every unit in this comparison features Wi-Fi smart control. This allows you to monitor and adjust settings remotely via a smartphone app. You can schedule operations or change temperatures from anywhere with an internet connection, regardless of which brand you choose.
