Mitsubishi Heat Pump Installation in San Mateo
This project in San Mateo, CA was a full heat pump installation for a home that wanted one system to handle both heating and cooling reliably. We installed a new Mitsubishi 2.5 ton heat pump and built the electrical circuit it needed from the ground up, since the home didn’t have the right wiring in place for a system like this.
The job took our crew, Konstantin and Eldar, about nine hours on site. That’s typical for a heat pump installation that includes new electrical work rather than just swapping equipment onto an existing circuit — the wiring, the disconnect, the surge protection all have to be done correctly before the unit itself even gets set.

Setting the Mitsubishi heat pump in place
The air handler went into the attic, tucked between the roof framing where it ties into the existing ductwork. We ran new refrigerant lines and condensate drainage to support it, and sized the whole system at 2.5 tons to match the heating and cooling load of the house. If you’re comparing options for your own home, our heat pump installation page walks through how we approach sizing and layout on jobs like this one.
Along with the heat pump itself, we added a surge protective device to help guard the new equipment’s electronics, and a smart air cleaning system to support indoor air quality now that the whole house is running through one heat pump system. We also pulled the city permit for the install and finished with a maintenance check before wrapping up.
Electrical and line set finishing work
Outside, the new line set was run up the wall and covered cleanly, which keeps the refrigerant lines protected from the weather and keeps the exterior looking tidy — not something we skip even when it’s not the flashiest part of the job.
Every heat pump installation we do in San Mateo gets treated the same way: proper electrical groundwork first, correct sizing for the home, and a finish that doesn’t leave loose ends for the next contractor or inspector to sort out. This one checked all of those boxes.

“Nur HVAC recently installed a heat pump (so we could finally have cool air during the summer!) and a new furnace since we still prefer to heat with gas. I could not be more pleased. I obtained estimates from 3 companies, including Nur. One was the Costco installer. They were nice but very expensive and didn't have the greatest post-install reviews. Still, I considered them. Another company provided what seemed like a pitch for a time share, complete with an album showing their reviews. This lasted close to 20 minutes! Nice company but out of the ballpark on price (maybe the presentation was intended to make you forget the final price?) and the estimate ran multiple pages which made comparing options impossible. Then came Artur with Nur HVAC. He was prompt, provided an easy to read, no nonsense estimate comparing options and did not try to upsell me by actually recommending less expensive options. They also had the best price no matter what we went with. The team which did the install was efficient, prompt, did solid work and were extremely polite. The job was so well done that when the city inspector came by for the final sign off, he was impressed by the work and told me that he has never had a problem with Nur. He explained how others take short cuts and how he is able to spot the problems. He told me Nur HVAC was one of only a handful of companies that always passed inspection as the installs were safe and properly done. I could not praise Artur and his team more! You will not find a more polite, professional and hardworking company that provides such great value for the money.”
“Nur HVAC are great company for HVAC. David, Alexander, Constantine and Arthur are very helpful and they are all knowledgeable and experienced with HVAC. They are very competitive in price and they have quality HVAC and the workmanship is excellent. We are very happy with this company.”
“My a/c unit stopped working, and I needed someone to come check it out and complete necessary repairs. When I requested quotes in Yelp, NUR HVAC was prompt in reaching out and scheduling an appointment for the following day. The following day the tech notified me that he was on his way, which was great as I was out running errands. I was able to arrive before he did - allowed me to compose my thoughts before his arrival. He did a diagnostic and resolved the issue in less than an hour. Afterwards, he explained how to best maintain the unit to avoid costly issues in the future. All in all - the diagnostic test and service completed cost me less than $100 - great value.”

“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!”
“We had old gas furnace replaced with heat pump and condenser. David gave us a very competitive bid. Both Alexander and Constantine are great crews replaced our furnace in our crawl space. The workmanship is excellent. They are very knowledgeable. David really care for his clients, he even came late at night to teach us how to setup the control because we are old folks don’t know how to download with wifi for the control. Arthur is very friendly, he waited patiently for the city inspector. Everything goes smoothly for this project. We are very happy to have this company got do the job.”
“Very pleased with their heat pump installation. I got three quotes and theirs was just a little lower than the others, but I chose them because they explained everything very well. They did not try to upsell like the other companies, which I appreciated. Installation went quickly and everyone was very pleasant. Photo with Arthur and our heat pump. Update, year and a half later: everything is working well. They helped me apply for the rebate after it was installed. I asked if I should do maintenance and they showed me what kind of filter to get. David came by and checked everything over (2nd photo) and didn't even charge because nothing was needed beyond changing the filter.”
“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.”
“We recently hired Nur HVAC, from a friend’s recommendation, to install a new heat pump and AC unit, and we couldn’t be more satisfied with the entire process. The installation was done on time and with great attention to detail by Ildar and …”
“I am writing this review hoping that it would help others when selecting the company to trust new installation of a Heat Pump system. We started with a few quotes that included visits. NUR seemed to be the best of the three both in terms of knowledge and desire to please the client. Upon completion and using the system for a couple of months I can tell you that it was the right choice. NUR team even helped with guidance on insulation (which we were thin with) and most recently, power outage had tripped a fuse. Over time, we dealt with 5 team members led by Davit each extremely professional took time to answer any questions and make sure that we are satisfied before departing.”
“My evperience with Nur Hvac was a pleasant one. Fedor was very accommodating and cooperative! The crew was very efficient and clean. I am glad I chose this company!”
“I highly recommend Nur HVAC! They upgraded my old split furnace HVAC with a heat pump HVAC retrofit. Fedor and the installation team showed outstanding professionalism and craftsmanship in all phases of the project: * Detailed initial project scoping tailored to my home's needs * Fast, friendly communication from start to finish * Solved new complexities we encountered on site * Collaboratively discussed alternative solutions, never felt pushy * High work quality I would absolutely choose Nur again for future HVAC work.”
“I had a great experience working with Nur Hvac. They coordinated installation of heat pump with my general contractor and there were zero issues during the project. I am mighty impressed by the Elias and team.”
“David and his crew helped install a heat pump for our house. Before that, we only had a heating furnace and would dread the increasingly hot summers. The crew did a fantastic job installing the heat pump and working with us through the permit process with the city. Would definitely recommend them for any HVAC related work!”
