FAQ

What is the Olmo Sierra ductless mini split series?

The Olmo Sierra Series is a value-oriented ductless mini split line with inverter technology, offering 9,000 to 36,000 BTU. Designed for single- and multi-zone setups, it includes Wi-Fi-ready controls, full install kits, and ENERGY STAR®-qualified models with SEER2 ratings up to 21.

How energy efficient is the Olmo Sierra series?

Efficiency ranges from ~19–21 SEER2 depending on capacity. Smaller units (9K–12K BTU) reach the highest SEER2, while larger systems maintain solid energy performance for moderate climates.

What features come with the Olmo Sierra mini splits?

Standard features include Wi-Fi control (via Smart Kit), remote, self-cleaning coil, Turbo mode, auto-swing louvers, GoldFin anti-corrosion coating, and low-noise indoor operation (~30 dB). Heating is effective in moderate cold weather but not intended for extreme subzero conditions.

Who is the Olmo Sierra series ideal for?

Best suited for cost-conscious homeowners who want reliable comfort in rooms, garages, or home additions under 1,500 sq ft. For colder climates, a cold-climate or Hyper Series model is recommended.
