Carrier Heat Pump Installation in San Carlos

October 21, 2026 2 min read
Share

This San Carlos home needed a complete heat pump installation, not just a swap of the outdoor unit. The homeowner had reached out for an estimate a few weeks earlier, and once the scope was set, our crew spent a full day on site putting in a new high-efficiency Carrier 3-ton heat pump system that handles both heating and cooling for the house.

A job like this is never just about the outdoor unit. Getting a heat pump to run well for years depends just as much on the details around it — the ductwork it breathes through, the electrical circuit feeding it, and the drain line carrying condensate away. We treated all three as part of the same job.

Ductwork and airflow

We resealed and tidied up the return air filter opening so the new system pulls clean, unrestricted air, and mudded the filter frame in place for a lasting seal. The supply duct boots were resealed with mastic where they connect to the trunk line, cutting down on the air leaks that quietly waste a system’s capacity.

Electrical and drain work

Because this was a full electrical system installation, our crew ran new wiring and set up a dedicated disconnect for the heat pump, along with a surge protective device to help the equipment ride out power spikes. Every junction was wired clean and mounted securely before we closed anything up.

On the condensate side, we installed new PVC drain piping with proper slope and primer joints so moisture from the indoor coil has a clear path out, which matters a lot for equipment tucked into attic or crawlspace areas.

We also set up a new disconnect panel outside for the heat pump circuit, wired and grounded to code.

The job also went through the city permit process and qualified for a Peninsula Clean Energy rebate, which is a nice bonus for homeowners upgrading to a heat pump system in this area. If you’re weighing a similar upgrade, our heat pump installation page walks through how we approach these projects from estimate to final startup.

Jobs like this one are why we like to slow down and get the supporting details right — the duct seals, the wiring, the drain line — instead of just bolting on a new box outside. It’s what keeps a heat pump quiet, efficient, and low-maintenance for the long run.

“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.”

“These guys are the best. After checking around, we went with NUR for a new Carrier furnace and a/c installation. Their pricing was fair, no surprises, and the quality of the installation was excellent. Even during the permit process the town inspector commented on how good everything looked. Here is the big thing: Everyone I dealt with at NUR was friendly, courteous, and professional. There were a couple of glitches along the way which happens with a project like this, but NUR was always responsive and took care of things promptly. I couldn't ask for more and can highly recommend.”

“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.”

“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!”

“This is the 2nd project I've done with NUR, and similar to the first time, I am a happy customer. From start to finish, NUR (in particular technician, Adlan) is completely professional. They are diligent and timely with their responses and scheduling. Adlan came out and diagnosed our 20 year old A/C system and was able to revive it, but prepared us with options for the future should the system go out again. He was extremely thorough in explaining these in layman terms. HVAC systems will always need maintenance and repairs, that's a given. However, I know that I have an honest, value-added, and well-run company to work with in NUR. Highly recommended!”

“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!!!”

“With summers getting hotter every year, we finally decided to seek out someone to install an AC system. We opted to get everything done in one go, so we replaced an outdated furnace, installed new air ducts & vents, and decided on an efficient A/C unit. Nur HVAC was reasonably priced, not the most expensive, not the cheapest, but had the best communication, clear outline on the work being done, and the actual workmanship of the install was very professional. Very happy we went with this company. The attention to detail was top notch, service was friendly, and the equipment is so quiet we barely notice it when it's on. Only regret is not having done it sooner.”

“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.”

“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 had an old furnace replaced with a new heat pump and air handler. I was impressed by their initial on-site inspection: the representative noticed that the new air handler would be wider than the existing one, which would require that our water heater be moved several inches for clearance. No other company noticed that. Overall, communication was excellent. They answered all questions and provided the city work permit application number so I could track approval process with the city. Work went smoothly and was finished in a few days, much sooner than what I had anticipated. Very good experience, would recommend to anyone.”

“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.”

“We recently used Nur HVAC to install a new heat pump and completely redo the ductwork for our whole-home HVAC system, and the experience was outstanding from start to finish. Fedor was incredibly knowledgeable and guided us through every step of the process—from initial planning to final completion. He was always available to answer our questions, no matter how small, and his oversight gave us total confidence in the quality of the work being delivered. Eldar handled the installation and did a fantastic job. The work was completed efficiently, with great attention to detail and craftsmanship, and everything was finished right on schedule. We couldn’t be happier with the results and would absolutely recommend Nur HVAC to anyone looking for reliable, high-quality HVAC services.”
