Mitsubishi 2.5 Ton Heat Pump Installation in San Francisco, CA
Cooling and heating a home in the city’s fog belt calls for equipment that runs quietly and sips energy, and this heat pump installation in San Francisco delivered exactly that. We removed a tired, aging system and replaced it with a compact 2.5-ton Mitsubishi heat pump that keeps the house comfortable all year from one efficient outdoor unit.
What we installed
The Mitsubishi condenser was mounted on the rooftop, where it stays out of the way and pulls in clean air, then linked to a matched indoor air handler through a new, fully insulated refrigerant lineset. Because the home was moving on from an older setup, we also completed a full electrical system for the equipment, pulled a permit through the city, and finished with a HERS test that the system passed. Every plenum seam and duct connection was sealed so conditioned air reaches the rooms instead of leaking into the framing.

Why a heat pump works for San Francisco homes
San Francisco’s mild marine climate is ideal for a heat pump. Winters rarely turn bitterly cold and summers stay cool, so a right-sized 2.5-ton unit can carry the whole load without wasting energy. One system now handles both heating and cooling, which means fewer parts to maintain and no gas burner running inside the house. Rooftop placement also frees up scarce ground-level space on a tight city lot.
Careful commissioning is what makes a system like this last. We verified the electrical connections, checked the refrigerant charge, and confirmed airflow before signing off.

“NUR HVAC just completed installation of a Mitsubishi heat pump system in my San Francisco home, replacing a 38-year-old Lennox gas furnace. I couldn't be more pleased with the quality of the work and the professionalism shown during the process. In particular, I wanted to commend Artur and Vladimir, the NUR technicians who did the beautiful install. Both guys were extremely polite and respectful, for example, putting on shoe covers whenever they entered the house. Artur was also very fastidious in running the ancillary electrical feeds to my main service panel. What a neat job! Fedor, who came to do the initial assessment, was a great resource and answered all my questions regarding scheduling, warranty, maintenance, etc. He offered several options during the bidding process without any pressure to come to a quick decision or attempts at "upselling." In the end, their quote was very competitive, and fair given the quality of the work and the final product. Being a Mitsubishi Diamond Contractor, NUR was able to offer a 12-year warranty on parts and labor. The bottom line is NUR is a top-quality outfit and it was easy to see that they take great pride in their work and genuinely care about their customers. NUR may be the best contractor I've ever used. Definitely, 5-Star!”
“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.”
“I cannot recommend Artur and the team behind NUR HVAC enough. I thank them every single day that my house is so much more comfortable than it was. Their installation of my heat pump was top-notch, and they didn't deceive me like a lot of other contractors. Stand-up guys doing excellent work at a reasonable price. You will never regret hiring them. And if even the tiniest thing goes wrong, they will come back and make it right, at no additional cost. If you need an honest, trustworthy HVAC installer, they are by far the best I've found. Super-sweet people and incredibly skilled engineers. You really can't ask for anything better than that.”
“The technician showed up on time, he was able to diagnostic the issue (my original installer wasn't able to figure it out) with our 5 zone heat pump. He suggested a few options with transparent pricing and no pressure to commit. We agreed on a fix and he was able to fix it right away. 10/10 would recommend.”

“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.”
“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.”
“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!"”
“I used Nur to install a new heat pump and they were terrific. I sought quotes from a number of competitors. Not only were they competitively priced but they have been super responsive and professional throughout. Fedor patiently and thoroughly responded to every question that ChatGPT could throw at him (through me)! The installation team - Alex and Vadim - were awesome and worked went above and beyond.”
“I’m very happy I chose to go with Nur HVAC. Not only was their pricing fair, but the quality of their work was excellent. My team—Fedor, Sergii, and Alex—completed the project within the estimated timeframe, even after running into some unexpected challenges along the way. They were patient with my concerns and took the time to explain each step of the process. Working in a city apartment can be tricky, but Sergii and Alex were very careful with their tools and machinery, ensuring nothing was damaged in my tight space. They were also extremely accommodating, thoughtfully laying out the pipes to meet my HOA’s specific requirements. Communication throughout the project was always clear and transparent. I highly recommend Nur HVAC to anyone looking for reliable, professional service.”
“Amazing quality of commitment, service, and communication. Would highly recommend this company!”
“Everything was smooth and seamless. I got several quotes and chose them in the end. They were able to provide accurate information and were patient to answer all my questions. They helped plan the install and apply for the permit. Installation by Shalai and Alex was efficient and on schedule. All in all a great experience. Do not hesitate to get them as your contractor!”
“We had an excellent experience with this HVAC company from start to finish. Fedor was incredibly prompt and professional at every appointment, provided a clear, comprehensive job specification, and the pricing was very fair and transparent. They installed a Mitsubishi ceiling mini split, and the installation itself was flawless. His installer, Volodymyr, and the rest of the team truly went above and beyond — they could not have worked harder, nor been nicer or more conscientious in our home. They were respectful, detail-oriented, and left everything spotless. It’s rare to find a company that combines responsiveness, fair pricing, and such high-quality workmanship. We highly recommend them.”
