Carrier AC and furnace installation in Palo Alto
This fall we finished a full Carrier AC and furnace installation at a home in Palo Alto. The job started with an estimate visit in late August, where we looked over the old system, the attic and the side yard where the condenser lived. In early October our crew came back and spent about nine hours putting the new equipment in place, inside and out.
Out with the old condenser
Here is what we found on the estimate visit: a gray condenser that had clearly put in its years, squeezed against the siding next to the electrical disconnect and the irrigation controller. It worked, but it was dusty, dated and sitting right on the gravel.

Same wall, same spot, after the swap. The new Carrier outdoor unit sits on a fresh concrete pad, bolted down at the feet and set slightly off the wall so it has room to breathe. The existing disconnect and conduit stayed where they were, so the side of the house looks almost the same, just with a much cleaner unit in the middle of it.
From the side you can see the refrigerant line set leaving the unit, wrapped in insulation and running low along the wall toward the house. Keeping the lines insulated matters here: it protects them from the sun and keeps the cooling working the way it should.
A new Carrier furnace in the attic
The other half of the job was up in the attic. The new Carrier gas furnace is a horizontal unit, which is what you want when the attic is low and every inch counts. We set it on its platform, tied it into the supply and return ductwork, and wrapped the transitions in insulation.
A few details worth pointing out in these photos:
- A yellow flexible gas connector runs from the shutoff valve to the furnace.
- The metal flue pipe rises straight up from the side of the unit.
- White PVC condensate piping carries water away from the equipment.
- Electrical feed comes in through armored cable to a box on top of the furnace.
Before we closed everything up, we worked through the control wiring so the furnace and the outdoor unit talk to each other properly. It is the part of the job nobody sees later, but it is what makes heating and cooling come on when they are asked to.
Why we did it in one visit
Replacing the AC and the furnace together means one day of disruption instead of two, and both halves of the system are matched from the start. If your own system is getting older and you are weighing the same kind of upgrade, take a look at our HVAC installation page, and we are always happy to come out and take a look in person.

“I had a great experience all around with Nur HVAC. Scheduling with Regina was a breeze, and Adlan, our technician, was fantastic. Adlan quickly diagnosed and fixed an issue with our 20-year-old AC unit on the spot without trying to upsell anything. Beyond the quick repair, he took the time to walk me through his process for diagnosing/assessing our AC system as well as the steps for a routine furnace maintenance - I learned a lot along the way. Highly recommend NUR HVAC, and especially Adlan!”
“Fair and honest contractors are hard to come by these days, but NurHVAC absolutely fits that description. I was referred to them by a friend, and I'm glad I took the recommendation. We needed to replace our old gas water heater, which was nearing 15 years old. From start to finish, their communication was excellent. Artur was my coordinator and Shalai was my installer. They were honest, transparent, and took the time to answer every question I had. They walked me through the pros and cons of each option without any pressure and even guided me through the rebate process, which made everything much easier. What really stood out was their commitment to customer service. The installer stayed until 9:00 PM to make sure everything was working properly so we wouldn't have to spend the night without hot water. He absolutely didn't have to do that, but it showed how much he genuinely cared about doing the job right. When the work was finished, he cleaned everything up so well that you wouldn't have known a major project had taken place in my garage. If you're looking for a company that's honest, knowledgeable, and truly goes above and beyond for its customers, I can't recommend NurHVAC highly enough.”
“Honest and meticulous. They quoted me a competitive price for work that they expected to complete within a few days. The time to finish the job increased, but the price did not. It's clear that they are *very* careful and detail-oriented during installation. Fedor and the rest of the team also make everything before the work very easy; figuring out what you want, advising what to do, and communicating about scheduling/logistics. Very happy overall, would recommend them without hesitation. My wife and I have already used them twice: adding a central heat pump and later augmenting it, in select rooms, with mini splits.”
“Our job wasn't easy, but Fedor and Sergii absolutely crushed it! Other companies told us it couldn't be done or would be way too expensive. NUR HVAC took it on, finished in just seven days, and stuck to the agreed price--no surprise add-ons or "we found this..." nonsense. We installed a 3-ton and 2.5-ton Mitsubishi Smart Multi-Split Heat Pump system (MXZ-SM60NA). Our house has two zones, and we wanted to add air conditioning. Since our two furnaces were nearly 17 years old, we decided to go all-electric with a heat pump system. The craftsmanship was top-notch, communication was consistent, and the whole experience was fantastic. It wasn't cheap, but compared to other quotes, the price was mid-range--and totally worth it. We were approved for the $4,500 HEERA rebate, but that got shut down (thanks, federal government). We did apply for the $1,500 PCE rebate and are hoping for a federal tax credit next year. Fingers crossed!”
“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!”

“We used Nur HVAC to replace gas furnace with a heat pump inverter, replace the aging duct work and gas water heater with a heat pump water heater, all in the same contract. Our project manager, Arthur was on-time for the scoping appointment. He took time to understand our needs, investigated the attic, ducts and all the existing equipment, before making any recommendations. He designed the optimal system for our house to be cost effective, provide highest comfort and be energy efficient. He was not pushy and was upfront about the ballpark estimates and timeline. He also walked us thru the various rebates that are available for the replacements from local utilities. Arthur’s quote was very competitive, in fact better than those quoted to us by Costco referred contractors. Nur’s installation crew - Eldar, Bhakridin, were very professional and thorough. They didn’t rush the job and left the job site clean and clutter free each day. They accommodated our requests for placing the electrical wires and conduits so they are not in the way. All the equipment both indoor and outdoor were cleanly laid out, secured and wiped down before hand off. Always smiling and respectful, one of the best installation crew we have had. As a white glove contractor they took care of all the permitting, inspection paperwork w/ the city, all the paper work for us to receive the rebates. They even completed the warranty registration with the manufacturers for all the equipment! We would highly recommend Arthur and Nur HVAC to anyone in the Bay Area needing heating and cooling solutions. We would definitely be going back to them ourselves when the need arises.”
“I highly recommend Islam from Nur HVAC to anyone needing reliable AC work. My AC went out and I had three different HVAC companies come by to look at it. None of them could fix the problem, and one company tried to tell me I needed a whole new zone board and two new dampers for several thousand dollars. Islam came out, listened carefully to everything I told him about what the previous technicans had said, and then did his own thorough troubleshooting. It was over 90 degrees out, and he spent time up in my hot, tight attic crawl space inspecting the indoor zone system and checking the outdoor condenser. He kept me updated the entire time on what he was testing and finding. Through his diagnosis, he proved that my dampers were actually working fine and that only the zone board needed to be replaced. Before doing any work, he gave me a clear quote upfront that came out to hundreds of dollars--saving me thousands compared to the other company. He installed the new board, double-checked that all the zones, thermostats, and dampers were working properly, and didn't leave until the system was running cold. Islam was punctual, polite, honest, and extremely hardworking. If you want AC work done right with technical competence and transparent communication, ask for Islam at Nur HVAC. I'll definitely be hiring him again.”
“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.”
“5/5 Stars - Highly Recommend Adlan and Nur HVAC! We had an exceptional experience with Adlan from Nur HVAC today. He is a consummate professional—extremely thorough, transparent, and honest. Our AC was completely out of refrigerant (6.5 lbs low), and instead of pushing an expensive and potentially ineffective nitrogen test on a hidden leak, Adlan gave us a practical, data-driven strategy to get our cooling restored for the summer while tracking down the issue. He thoroughly explained the system’s metrics, including a high compression ratio, and gave us fantastic, low-pressure advice on how to plan for our home’s long-term HVAC compliance and transition over the next couple of years. On top of that, he diagnosed a long-standing airflow bottleneck to our second floor. He took the time to inspect our complex crawlspace ductwork, confirmed the structural equipment is in great shape, and laid out a clear plan to return for a whole-house air balancing service. Finding a technician with this level of technical expertise and genuine integrity is rare. Request Adlan if you want the job done right. Thank you, Nur HVAC!”
“I recently hired NUR HVAC to remove an old HVAC system, correct issues from a previous improper installation, and install a new system with air conditioning in my new home. From start to finish, my experience was outstanding. Fedor was fantastic to work with. He took the time to explain everything thoroughly, answered all of my questions, and kept me informed throughout the entire process. The communication, quality inspections, and overall professionalism exceeded my expectations. The installation team, Vitaly and Leandro, were equally impressive. They removed the old system and installed the new one with great attention to detail. They were always punctual, courteous, and clearly very knowledgeable about their work. Their craftsmanship was meticulous, and it was obvious they took pride in doing the job right. At the end of each day, they cleaned up after themselves and left the work area neat and organized. It’s not often that you find a company that combines excellent communication, quality workmanship, and outstanding customer service, but NUR HVAC delivered on all three. The new system is working great, and I have confidence that the job was done correctly. I would highly recommend NUR HVAC to anyone looking for HVAC replacement, air conditioning installation, or service. Five stars without hesitation.”
“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 is my second experience with these awesome people. Nur HVAC installed a heat pump a year ago and I remembered how professional they were. So when my water heater broke few weeks ago I called them again. Fedor called me and came over the same day to personally inspect my setup. He gave me three options for my water heating needs and coached me through the selection process based on my current and future needs. This was Monday and by Wednesday I had everything fixed! As always, professional and courteous service. While Fedor was here I got to talk to him about options for more even heating and cooling distribution in my house. Even though it was not related to problem at hand, he patiently explained to me what my options were and then turned me onto a new solution using smart vents. This ended up being 10x cheaper than dual zoning and works a 100 times better. This guy is so smart, he must have a Ph.D. in HVAC!!! Thank you Fedor and I can’t recommend this team highly enough!!!”
