Mitsubishi MXZ-5C42NA heat pump installation in San Anselmo, CA
Another project wrapped up: a Mitsubishi MXZ-5C42NA multi-zone heat pump installation, professionally completed in San Anselmo, CA. This outdoor condenser anchors a ductless setup that can drive several indoor zones at once, giving each space its own independent temperature control without the cost or mess of adding ductwork.
The MXZ-5C42NA is built for whole-home comfort. It pairs heating and cooling in a single system, runs efficiently in our mild Bay Area climate, and stays quiet enough that you’ll forget it’s working. Because it’s ductless, conditioned air goes straight into each room, and one zone can be cooling while another is heating to match how the home is actually used.

Why this system works so well
- Zoned heating and cooling. Each indoor head is controlled separately, so every room can be set to the temperature its occupants actually want.
- Energy efficiency. Inverter-driven heat pump technology only uses the power it needs, which helps keep monthly utility bills in check.
- Quiet, reliable performance. The system runs smoothly and steadily through both heating and cooling seasons.
- Clean, low-impact setup. The install was completed with minimal disruption to the home and a tidy, professional finish.
This kind of multi-zone heat pump is a great fit for homeowners who want consistent comfort across several rooms and the flexibility to condition only the spaces in use. Every Nur HVAC installation is finished with clean line sets and full system testing and commissioning, so it’s ready to perform from day one.
Thinking about a multi-zone system for your home?
If your house has rooms that never seem to hold the right temperature, or you’re adding comfort to spaces that ductwork can’t reach, a setup like this one is worth a look. Our team designs and installs multi-zone heat pump systems matched to how each home is actually lived in. Reach out to Nur HVAC and we’ll help you figure out the right configuration for your space.

“NUR installed a ductless multi-zone Mitsubishi mini-split system for us this spring after our 100-year-old lovely monster of a gas boiler died. It's so far out of code that no one will repair it, and we were tired of being cold! The new system is electric with a heat pump on the roof, and it includes AC for the six days a year when my usually foggy neighborhood needs it. We chose NUR because they offered competitive prices and clear communication, and they were able to place the indoor units exactly where we wanted them. The installation took just a couple of days and they were kind and efficient. If you are looking to get a job like this done, you should give them a call.”
“Nur HVAC replaced my old gas furnace and replaced it with a Mitsubishi heat pump. They also redid my ducts. David initially came to my house to give me a quote, he offered me a ductless option which no other HVAC companies suggested, and was clearly experienced in HVAC installation, and gave me the best quote for top of the line equipment. Other HVAC companies sent salespeople, but David was technical and addressed my concerns and questions with great detail. The team that installed my new heat pump went above and beyond - they fixed some loose wiring in the crawlspace and adjusted the gas and exhaust lines for my water heater to save space. The installation was well done, the wiring and new lines they ran were clean and organized, they ensured that all the ducts were sealed and the airflow was balanced to all my rooms. I'm very happy with my new hvac system and would highly recommend Nur HVAC!”
“Our 25+ years old gas furnace ran into issues and we could have just replaced the part and limped along for a while. We decided to do a like-for-like replacement...we got a quote (I won't mention the name of the vendor) and got a quote for a Bryant a/c/ gas furnace (lower than the Carrier a/c that we had) and the quote was pretty high ~ $25K and NO REBATES (this person did not even offer us the option of a heat pump). Our son suggested going to Yelp to get a project quote given we were spending so much money - from the 8 companies we talked to we zeroed in on Irbis and NUR and both companies were solid. Our main reason for going with NUR were the following : 1) With NUR we dealt directly with the Owner not a sales team : David - he is a no-nonsense, straight shooter who is extremely knowledgeable about all things HVAC. 2) Offered the right spec and quality of machine - He told us we should go with the Heat Pump (replace gas furnace) given we had solar and he offered us the complex split zoning for our single family house. Upgraded our carrier a/c to a Mitsubishi Heat Pump (see picture) 3) Reasonable Quote, High Quality work - He offered us an extremely reasonable quote for a high end heat pump, his technicians were top notch. Igor and Mikhail were brilliant - they spent a week at our place and were so polite, skilled and unobtrusive. They cleaned up after themselves every single day that they came in. 4) Helped me get the $3500 rebate from Peninsula Clean Energy 5) After install customer service is brilliant. I am doing this review after a month but these guys are beyond amazing when it comes to responsiveness to any questions or concerns. If I do any replacement of my HVAC and water heaters in the future - I will not look beyond NUR - they have my business for life”

“We replaced our 25-year old single phase gas furnace with a Mitsubishi HVAC heat pump this summer. Now that we’ve used it for both cooling and heating, I’d like to give the team at Nur a five-star rating for their clean, smooth installation. Communication was great and they were thoughtful about system design so that we don’t have exterior conduits. We are so happy with the operation of the system for heating: it is quiet and so much more effective than our old furnace. We can highly recommend Nur.”
“This is the second project I’ve done with this team, and there’s a reason I keep coming back: Trust. When my water heater went out, Fedor showed up the same day to walk me through my options. I have a tendency to "over-buy," and I was actually leaning toward an expensive heat pump model. Instead of just taking the bigger check, Fedor was honest with me—he explained that the ROI on that specific unit wouldn’t be recovered in my lifetime given complex electrical work required. Once we picked the right system for my actual needs, he had a crew at my house within two days to finish the install. They were professional, clean, and efficient. It’s hard to find an HVAC company that values integrity as much as they do. They’ve earned a customer for life!”
“I am extremely pleased with my new Mitsubishi heat pump installed by Nur HVAC. Everyone in California should use a heat pump due to the high cost of electricity, and Nur HVAC should be your installer. My installation was performed in two parts: the upstairs in Mar 2025, then downstairs in May 2026. I commend Nur HVAC for their patience during this protracted and difficult installation. After an initial assessment to determine my needs, the team arrived to plan the installation of the upstairs hardware. They asked many questions to figure it out. It only took 5 days for my on-site representatives Konstantin and Maxim to finish the work, which I felt was clean and neat; the electrical, refrigerant, and condensate lines blended into the existing arrangement seamlessly. By the end of day 5, I had hot and cold air at the touch of a button. About a year later, my remodeling had progressed enough for the installation of the downstairs units. Sadly, other contractors inadvertently cut the 220V supply line to the 2nd floor units. And while they meant well, these other contractors totally messed up the 220V supply line for the 1st floor units, running it to the 2nd floor breaker box instead! Maxim and Konstantin went above and beyond the call of duty, doing jobs that weren't theirs. They re-routed the 1st floor electrical line to the 1st floor breaker box, and got everything working. They were quick to suggest best placement of the indoor units. Additionally, they figured out a far better arrangement of the outdoor unit and refrigerant lines. The installation was more concealed and neat afterwards.”
“I hired Nur HVAC for a major upgrade to my home's system, and they did an incredible job. The project involved converting my entire house from a gas heat pump to a new all-electric Mitsubishi system, and they also installed a split unit in my garage. Their prices were very reasonable, but what truly stood out was the professional quality of the installation. The team performed a very careful evaluation of all my existing ducts and vents to ensure the new system was installed for optimal performance. The work speaks for itself. It's been almost two months since the installation, and everything is working top-notch. I'm super happy I chose Nur HVAC and highly recommend them.”
“This visit was a maintenance check on our 2 mini splits that were installed about 18 months previous . Islam D showed me how to clean the filters ( which was easy ) and he inspected the unit on our roof. The visit was prompt, professional and informative as I had several questions on the workings of the mini splits. We are very pleased with these units and the service we've received from Nur HVAC.”
“Heat pump. Other than last year, when Nur installed a furnace for us in another zone of our home, this installation of a second unit-----a heat pump----was among the best home services ever provided. The people who come to our home were kind, competent, professional, and fairly priced. No Bay Area Premium Pricing. Extremely helpful advising which unit to select, and managing rebate process. Everything was transparent. Total high-quality work, would give 10 stars if I could.”
“NUR HVAC did an outstanding job replacing our furnace and installing a new heat pump. Their quote was clear, detailed, and more competitive than all the others we received—and their high ratings gave us confidence. The installation went exactly as other reviewers described: professional, efficient, and high-quality. They really know HVAC and electrical systems inside out. We’re so glad we found NUR HVAC for our home project. They are an A+++++ company!”
“It is no coincidence that Nur HVAC has such positive reviews. This team is just as good as all of the reviews say. We had them upgrade our old gas furnace and gas water heater to heat pump units and I can say hands down that this was the most positive home improvement / construction project we've done. Fedor coordinated our project and was consistently responsive and helpful. He went above and beyond to make sure we got the equipment I wanted. Vladimir and Arthur performed most of the install and it went super smoothly and the equipment works perfectly. They were always courteous and communicative. We had one issue related to very high water pressure from the street and even though this wasnt their fault, Nur HVAC prioritized helping us solve the problem over the holidays. I could not recommend this team more.”
“Nur HVAC recently installed a mini-split system in our SF condo; one in the living room, and one each in the two bedrooms. They installed the heat pump outside on the balcony. I was impressed with their work ethic and the way they kept our space clean during the installation. They cleaned up at the end of each work day and were very respectful and thoughtful of our home, our dog, and us. They communicate clearly and quickly; I would highly recommend them to install an AC system.”
“I highly recommend Nur HVAC. They recently installed a heat pump system and two mini splits at my house. The units are extremely quiet and work well. I found all of the Nur personnel to be professional and courteous with excellent integrity. The mini split placement was tricky in one of the rooms, and they brought in a bigger team to carefully consider the pros and cons of various options before making a final recommendation and explaining the considerations to me. They did a fabulous job of communicating with me and they did high-quality work. The installers even painted exposed outside pipes to match my stucco, so the pipes are quite unobtrusive. The electrical inspector came yesterday and was smiling when he remarked to me, "They did nice, clean work!"”
