Mitsubishi MXZ-4C36NA ductless mini-split installation in San Francisco, CA

This project was an installation of the Mitsubishi MXZ-4C36NA multi-zone ductless mini-split system in San Francisco, CA. It’s an ideal solution for homeowners who want to heat and cool several rooms with precision and efficiency, all without bulky ductwork. Because the system is ductless, conditioned air is delivered straight into each room rather than traveling through ducts, which avoids the energy losses that ducted systems often experience.

As the outdoor condenser in a ductless system, the MXZ-4C36NA supports multiple indoor units, so each connected space can be set to its own temperature for truly customized comfort. One room can be cooling while another is heating, and unused rooms don’t have to be conditioned at all, which is part of what makes a multi-zone setup so flexible and efficient.

Why this system works so well

• Multi-zone flexibility. The system connects up to four indoor units for personalized, room-by-room temperature control.
• Energy-efficient inverter technology. It adjusts output to match demand, helping lower energy bills while keeping the home comfortable year-round.
• Whisper-quiet operation. Low sound levels mean comfort without intrusive HVAC noise.
• Minimal disruption. Because it’s ductless, installation doesn’t require major renovations.

A multi-zone mini-split like this is a great fit for homeowners who want efficient, flexible comfort across multiple rooms without adding ductwork, and it’s especially useful in homes where running new ducts would be difficult or costly. Every Nur HVAC installation is completed with clean line sets and full system testing and commissioning, so the equipment is properly charged, verified, and performing reliably from the very first day.
