This project covered the installation of a Mitsubishi M-Series ductless system, set up as a two-zone heat pump that delivers independent temperature control to two separate areas of a home in Belmont, CA. The outdoor unit and indoor units were installed and connected through refrigerant lines and electrical wiring. Nur HVAC installs systems like this across the Peninsula and South Bay, including Milpitas.
The system pictured uses a Mitsubishi MXZ-4C36NA3 outdoor heat pump (U1) paired with a Mitsubishi MSZ-FS09NA indoor unit (U2). With two zones, occupants can set the comfort level in each area independently, conditioning only the spaces that are in use.

How the M-Series ductless system works
- Outdoor heat pump: the MXZ-4C36NA3 houses the compressor and condenser coil, pulling heat from the outside air in heating mode and reversing the process to cool in summer.
- Indoor units: each indoor unit is mounted within its zone and comes with a remote control for adjusting temperature, fan speed, and mode.
- Two-zone control: independent control over two separate zones lets each area be tuned to its occupants’ preferences.
- Targeted efficiency: conditioning only occupied zones helps reduce wasted energy compared to cooling or heating the whole home at once.
Getting the installation right
A ductless install depends on correct placement of the indoor units and clean refrigerant and electrical connections to the outdoor unit. Nur HVAC plans each zone around how the home is used, then installs and connects the equipment so every area is comfortable and ready to run.
Is a ductless system right for your home?
Ductless systems shine in homes without existing ductwork, in additions, and in rooms that never seem to match the rest of the house. Because each zone runs on its own, there is no fighting over a single thermostat and no conditioning of empty rooms. If you have a space that stays too hot or too cold, a two-zone setup like this one is often the simplest way to fix it without major construction. We can help you plan the zones.

“After getting multiple estimates to replace our gas furnace and damaged ducting, we chose Nur HVAC and have been very satisfied with the workmanship and quality of our Mitsubishi heat pump mini-split setup and heat pump water heater. David was helpful in explaining why we should consider a ductless mini-split setup since we needed to remove all our old ducting. Nur HVAC was the only company to help us consider the options vs. just following what I thought was available. Their pricing is competitive, but I was most impressed with the installation of our 4 cassette indoor units - very clean, during and after what was probably a challenging 1-week install. Artur and Vlad worked hard and always checked in, let me know when they were out for lunch, and done for the day while I was working in and out of the house. Nur HVAC also assists with the rebates and financing options if available to you - as well as the permitting and final inspections. Great company and team, would definitely recommend!”

“It is pleasant experience doing business with them. David is very responsible and gave good suggestions on the overall design/installation options. The quote is competitive, work is done in 3 days with expected cost and workmanship.”

“Adlan came on time, was super professional, and got it fixed for a reasonable price. He went through the debugging very systematically: fuse blown -- but why? He checked each component along the path until we got to the culprit. And then he was checking why would that component fail and gave some recommendations. He made sure to clean the work area and was off. Thanks Adlan!”

“Everything you want from an appliance repair company. They showed up on time, they were polite, clean, efficient and gave a reasonable quote. Ours was a simple job. One of the lights on our Zephyr hood had been out of commission for years. Since I don't like the feeling of getting electrocuted, I finally decided to have someone look at it.The problem was diagnosed very quickly. They gave me a reasonable price quote and quickly fixed the issue. When the job was completed, I asked if, while they were here, could they take a look at a separate issue we had with our Robern medicine cabinet's built-in night light. Again, the problem was diagnosed quickly and fixed quickly. Nur Service is a new company and deserves and has earned our future business for sure!”

“I had a ducted heat pump system installed in the majority of my house, and a ductless mini-split installed in my family room. The workers were friendly, efficient, thorough and neat. They addressed all of my concerns.”
“I hired Nur HVAC to replace and install a new heat pump. Throughout the long duration of the project (with HOA, city permit and other stuff, this is inevitable), the team has been very professional, responsive and knowledgeable. Artur is up to speed of everything and answer any questions I have. Sergei and installation teams are on-time with high quality work. Last, their quote is also competitive.”
“Arrived on time, sent a photo of the person who would be responding to my home. They covered my floor and walk way where they would be walking and immediately began to work. The worked steadily and then cleaned after they were through. My new system is quiet, and working beautifully. STRONG recommendation for this company!”
“Fedor and Volodymyr are extremely profession and detail oriented for helping my HVAC and heat pump systems. Highly recommend it!”
“I tried a couple of different businesses for a cooling issue with my heat pump system and Nur engineers showed more patience and knowledge than the others. In addition they were also more reasonable on pricing, while focusing on fixing the actual root cause of the problem.”
“We are very pleased with our technician Adlan. He did a great service for us and was very thorough on checking through everything that can further improve the AC performance after fixing the main issue. I highly recommend the quality of his services and would not hesitate using the company again.”
“I had a great experience with Nur HVAC. They were quick to respond, punctual, friendly, and professional from start to finish. Their pricing was fair and transparent, and the quality of their work was excellent. I truly appreciated their efficiency and positive attitude. I would highly recommend Nur HVAC to anyone in need of reliable HVAC services!”
“Called them over the weekend and they arrived on time on Monday. Quick fix for a failed furnace motor. Finished the job in an hour. Very nice technician although a bit difficult to understand because English was not his first language.”
