Trading an older setup for a modern all-electric system, this heat pump installation in Emerald Hills gave the home a Carrier 3-ton system that both heats and cools while running cleaner and quieter than what it replaced. The project was permitted and finished to code, right down to a passing HERS test.

What we installed
Outdoors, we set the Carrier heat pump condenser on a solid pad with its own weatherproof disconnect, then connected it to a matched indoor air handler through a new refrigerant lineset. A change like this depends on the ductwork, so we resealed the supply boots and register connections with foil mastic tape to stop leaks and keep static pressure where it belongs. We also completed a full electrical system for the equipment, pulled the permit, and passed the required HERS test that verifies the ducts and system perform as promised.
- Installed a Carrier 3-ton heat pump condenser and matched air handler
- Ran a new refrigerant lineset between the units
- Resealed supply boots and register connections with foil mastic tape
- Completed a full electrical system for the new equipment
- Pulled a permit and passed the HERS test
Duct sealing is one of those details that quietly makes or breaks a system. Loose or leaky boots let expensive conditioned air escape into the attic before it ever reaches a room, so we took the time to wrap each connection tight and seal it properly for the life of the equipment.
Why Carrier heat pumps suit Emerald Hills homes
Tucked into the hills, these homes want steady comfort without a noisy, energy-hungry system. A 3-ton Carrier heat pump delivers efficient heating on cool mornings and reliable cooling on warm afternoons from one piece of equipment. Because we sealed the duct connections along the way, more of that conditioned air actually reaches the rooms instead of escaping into the attic, which shows up as better comfort and shorter run times.
Every connection was checked, charged, and tested before we called the job done. If you are considering a heat pump installation in your own home, contact Nur HVAC for a free estimate and a straightforward plan for the work.

“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!”
“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.”
“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!”

“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.”
“Last month, we contracted NUR HVAC to install three units of Mitsubishi ductless AC units to our house. The sales contact Artur was very professional, always addressed our questions very quickly and clearly. Their office support Regina was proactive and timely communicated important information for our awareness ahead of time. Their two technicians Maxim and Alksei have done done an excellent job to install the units and relevant pipes. We are very satisfied with the quality of Nur HAVC's work, their competitive price and excellent customer services, and definitely recommend this company for others who are seeking professionals to do the similar service. George and Amy from Redwood Shores, CA”
“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.”
“Purchasing a new furnace or HVAC system may not seem like a personal decision at first. Most people focus on the equipment itself, the price, the company’s reputation, and the research that goes into making the right choice. You interview several companies, compare features, warranties, pricing, and timelines, and eventually make a decision. But what you quickly realize is that you are also inviting people into your home to install a system you hope will serve your family for many years. The people doing the work matter just as much as the equipment they install. Nur HVAC Systems was one of several companies I researched and interviewed to replace my aging furnace, all of the ductwork throughout my home, and every register. This was not a straightforward installation. The furnace needed to be relocated, asbestos had to be professionally removed, and there were several other complexities that made this a challenging project. Nur was my final interview, and after meeting Fedor, I knew without hesitation that he was the right person for the job. After speaking with several companies, he was truly in a league of his own. He brought thoughtful, innovative, and cost-effective solutions that no one else had suggested. His experience and confidence immediately gave me peace of mind. The project began with the removal of old asbestos materials, coordinated by a team Fedor assembled and led by Antonio. They worked efficiently, meticulously, and safely, completing the job without a single issue. From there, the project moved on to removing the old furnace, ductwork, and registers before installing the entirely new system. Fedor’s team was nothing short of exceptional. Vitaliy, Leandro, and engineer Arthur were outstanding. When construction is taking place throughout both your basement and your main living areas, it inevitably becomes personal. Having these three professionals in my home was genuinely a pleasure. They worked incredibly hard, but they also worked intelligently. They were respectful, courteous, professional, and remarkably kind. What could have been a stressful and disruptive experience instead felt organized, comfortable, and surprisingly easy. Most importantly, the quality of their workmanship was outstanding. Every challenge that arose was handled with confidence and expertise. It was obvious that these men truly know their craft. I had complete trust in their abilities from beginning to end, and they exceeded every expectation. What initially drew me to Nur HVAC Systems was that I never felt like I was hiring a single salesperson or simply buying a product. I was hiring an entire team. A successful project depends on every person doing their part with excellence, and that is exactly what Nur delivered. From planning and communication to execution and craftsmanship, every member of the team reflected the same high standards. If you are looking for a company that combines technical expertise, integrity, professionalism, and exceptional customer service, I recommend Nur HVAC Systems without reservation. They didn’t simply install a new HVAC system. They earned my complete trust, and I would confidently hire them again and recommend them to my family and closest friends.”
“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.”
“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.”
“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 worked with the fine folks at Nur HVAC to install 2 mini-splits and an outdoor unit earlier this year. It was a nice experience from start to finish. They were very conscious of keeping the mess to a minimum and cleaning up after themselves. The technician who came by to do the estimate, Adlan, was very nice and explained everything clearly. He even repaired a blown fuse at no charge. The installation team, which included David, Eldar, and Alex, worked fast, but efficiently. They finished the installation that same day despite the setbacks like figuring out how to run the power back to the panel (our home has a weird configuration). They came back another time to take care of some inspection-specific requirements, but no issues with the final inspection. The company was also open to helping provide documentation for energy rebates. The only trouble we had was the slight language barrier, which made communication difficult sometimes. We had them provide two quotes, including replacing our existing heater, and the price of everything was very competitive with the other quotes we received. Overall, I felt they were reliable and met my expectations. I'd be happy to call them back for any HVAC needs I have in the future”
“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.”
