Buying Guide
What size should you choose for a garage? Measure the space and consider heat load from equipment, sunlight, and insulation. A 9,000–12,000 BTU unit fits many smaller garages, while larger garages may require 18,000 BTU or more.
Which features matter most? Inverter compressors (SEER2 ratings) save energy; remote/app control offers convenience; dehumidification helps with damp garages; self-cleaning functions reduce maintenance needs.
Installation considerations: wall-mounted units save floor space but require proper mounting height and clearances. Some systems ship in multiple packages; verify all parts before starting. Ensure electrical supply compatibility and dedicated circuits if needed.
Energy efficiency versus upfront cost: higher SEER2 ratings improve long-term savings but may come with a higher purchase price. Evaluate total cost of ownership, including installation and potential electrical upgrades.
Control options: WiFi or app-enabled models provide flexibility to manage temperature remotely, which can be helpful for pre-cooling a space before use or coordinating with home systems.
