Quad-Zone Mini Splits: Balanced Climate Control for Four Areas

OLMO Quad Zone Mini Split system

A Quad Zone Mini Split is a type of Multi-Zone system that connects four independent indoor units to a single outdoor condenser unit. This configuration allows for heating and cooling in up to four distinct areas of a home or business, offering flexible and powerful whole-home climate control.

Quad Zone systems deliver precise, independent temperature control for each of the four zones, meaning users in different rooms can set their ideal comfort level. This highly zoned approach eliminates energy waste associated with traditional HVAC systems, providing exceptional energy efficiency and reduced utility costs.

Why Choose OLMO Quad Zone

  • Four-Room Customized Comfort: Achieve total climate independence across four separate spaces, mixing indoor unit styles and capacities to perfectly fit bedrooms, living areas, and additions.
  • High SEER2 Efficiency: Utilizing OLMO's inverter technology, our Quad Zone systems maintain consistent temperatures and achieve high SEER2 ratings, translating to lower monthly energy consumption.
  • Simplified Installation: By utilizing a single outdoor unit, the Quad Zone system simplifies the installation footprint and is less invasive than installing four separate single-zone units.
  • Dependable Year-Round Performance: Our units are built with solid components and backed by comprehensive warranties and US-based customer support, ensuring reliable heating and cooling, even in extreme conditions.

Frequently Asked Questions

Find answers to common questions about our products and services.

A: No. Like most multi-zone systems, all four indoor units connected to the same outdoor condenser must operate in the same mode—either heating or cooling—at the same time.

A: First, perform a BTU calculation for each of the four rooms separately. Then, select an outdoor unit whose total capacity is sufficient to handle the sum of the BTUs for all four indoor units.

A: Yes, OLMO Quad Zone systems offer great flexibility, allowing you to mix different indoor head types (wall-mounted, floor consoles, ceiling cassettes) and capacities (9K, 12K, 18K) to suit the aesthetic and functional needs of each zone.

A: OLMO typically offers a solid limited warranty, including coverage on the compressor and parts, provided the system is installed by a licensed HVAC professional and registered within the required timeframe.

  • A: While four single-zone units may offer slightly higher nominal efficiency, the Quad Zone offers high efficiency through its variable-speed inverter technology and superior convenience with a single outdoor condenser. The Quad Zone is generally more efficient than trying to heat or cool four rooms using a central ducted system.
