How many mini split series are available, and which is the most popular?

Our catalog currently features more than five specialized mini split series ranging from compact 9,000 BTU single-room options up to powerful 24,000 BTU whole-zone systems. The most popular overall choice among residential homeowners is the Airtural 12,000 BTU system, which delivers 21 to 22 SEER2 efficiency, whisper-quiet 23 dB acoustics, and an optimal balance of price and performance. For colder regions experiencing severe winter drops, the SEERXtreme series represents the highest-performing alternative with hyper-heating capability down to -15°F.

What is the key difference between 115V and 208-230V mini split models?

The fundamental difference between 115V and 208-230V mini split units lies in the required electrical circuit and maximum cooling capacity. Models operating on 115V are engineered for standard 15-to-20 amp household outlets, making them ideal for DIY retrofits in smaller rooms, sheds, or garages without requiring main breaker upgrades. In contrast, 208-230V units require a dedicated double-pole breaker and are engineered to power larger capacities between 18,000 and 24,000 BTU, delivering maximum thermal output across broader living spaces.

How often is this directory updated, and what are the delivery guidelines?

This directory is refreshed quarterly to verify real-time stock status across domestic logistics centers and incorporate newly certified SEER2 ratings. Costway provides standard free ground shipping for all eligible mini split units within the 48 contiguous United States.
