mini split ac reviews 2020

Mini-split systems span small to very large spaces. Common coverage ranges in the results include: small rooms around 300–500 sq. ft., mid-size coverage near 500–1,250 sq. ft., and higher-capacity units covering roughly 1,500–2,000 sq. ft.

The listings show a wide range of cooling capacities. Representative sizes include 9,000 BTU and 12,000 BTU at the lower end, mid-to-high options such as 18,000 BTU, and larger units reaching about 23,000–24,500 BTU.

Most systems offer five common modes—Auto, Cool, Dry, Heat and Fan—and provide multiple fan speeds. The number of fan speeds is typically three or four, depending on the model.

Many systems ship with an installation kit that commonly includes the indoor unit, outdoor condenser, copper line set or connection pipes, communication wiring, drain hose and mounting accessories. Several listings recommend—or require—professional installation to ensure correct setup and warranty compliance.

Several listings describe washable air filters and easy-access filter designs, plus built-in cleaning features such as self-cleaning cycles or automatic self-diagnosis/cleaning functions to help maintain airflow and indoor air quality.
