How alternatives compare to Soleus Air 12
Della 10,000 BTU Wi-Fi Window Air Conditioner
The Della 10,000 BTU Wi-Fi Window Air Conditioner offers similar smart control via Wi-Fi but lacks the heating function found in the Soleus Air. It is a window unit rather than a through-wall design, meaning it occupies your window space instead of straddling the wall. The Della is lighter at 48.7 pounds compared to the Soleus Air's 64.6 pounds, making it easier to handle. Its dimensions are more compact, with a width of 18.6 inches and a depth of 17.3 inches. You get a similar 10,000 BTU cooling capacity. Choose this if you need a portable window unit without the heavy installation requirements of a through-wall model.
TCL 10,000 BTU Smart Window Air Conditioner
The TCL 10,000 BTU Smart Window Air Conditioner provides Wi-Fi connectivity similar to the Soleus Air but does not include a heater.

However, it is a much more powerful unit with 18,000 BTU of cooling capacity, compared to the Soleus Air's 10,000 BTU.

Frequently asked questions
Can I use a window unit instead of a through-wall AC?
Yes, you can use a window unit as an alternative. The Della, TCL, LG, GE, and ROVSUN models are all designed for window installation. This option is easier to install if you lack existing wall openings. However, window units occupy your window space, unlike the Soleus Air which sits flush in the wall.
Do these alternatives support smart home controls?
Most of the listed alternatives support Wi-Fi connectivity for smart control. The Soleus Air, Della, TCL, LG, GE, and ROVSUN models all include Wi-Fi features. This allows you to manage settings remotely via an app. You can adjust temperatures and modes from your phone without needing to access the physical unit.
Which alternative provides heating for year-round use?
Only the Soleus Air and the LG 18,000 BTU model include a heater. The other alternatives, including the Della, TCL, LG 10,000 BTU, GE, and ROVSUN, are cooling-only units. If you need winter heating, you must choose one of the two models with this specific feature.
Are there energy-efficient options among these alternatives?
The ROVSUN 10,000 BTU Inverter Window Air Conditioner is Energy Star certified. It uses inverter technology to maintain temperature efficiently. This makes it a strong choice if energy savings are your priority. Other models like the LG 10,000 BTU also offer efficiency, but the ROVSUN explicitly highlights its inverter and certification.
What is the maximum room size these units can handle?
The LG 18,000 BTU model is designed for large rooms and open areas. It has an 18,000 BTU cooling capacity. The 10,000 BTU models, such as the LG 10,000 BTU, are rated for up to 450 square feet. Smaller units are better suited for compact spaces or single rooms.
How do the dimensions compare to the Soleus Air?
The Soleus Air is longer at 31.8 inches but narrower in width. Window units are generally wider but shorter in length. For example, the LG 18,000 BTU is 30.5 inches long and 25.5 inches wide. The 10,000 BTU models are typically around 19 inches wide and 17 to 19 inches long.
Is a through-wall installation better than a window unit?
Through-wall installations offer better security and do not block your window view. The Soleus Air is designed for this secure setup. Window units are easier to install in existing frames but take up window space. They also may allow more noise infiltration compared to the sealed through-wall design.
Which model is best for small to medium rooms?
The 10,000 BTU models are ideal for small to medium rooms. The TCL, LG, and GE units fit this category well. They provide sufficient cooling for spaces up to 450 square feet. The Della and ROVSUN models also fit this range, offering smart features without the bulk of larger units.
