For this Redwood City home, we completed a 3-ton heat pump installation using a high-efficiency Carrier system to replace an older setup. The new heat pump handles both heating and cooling through the home’s ductwork, and we rebuilt the duct connections and electrical so the whole system runs clean, quiet, and efficiently.
What we installed
The 3-ton Carrier condenser sits on a solid pad along the side of the house, tied back to the indoor air handler with a fresh refrigerant lineset and a weatherproof disconnect. Inside, we rebuilt and sealed the supply and return plenums with mastic tape so conditioned air moves efficiently and the return pulls through a clean filter. Once the connections were complete, we evacuated the system, weighed in the charge, and commissioned it for both modes.

Why a Carrier heat pump works for Redwood City
Redwood City’s warm summers and mild winters are a great match for a heat pump: it delivers efficient cooling on the hottest afternoons and comfortable heating the rest of the year, all from one system. Swapping an older furnace-and-AC pairing for a single high-efficiency Carrier heat pump usually means lower energy bills, steadier temperatures, and fewer moving parts to maintain.
Sealing the duct connections properly is a step that’s easy to skip and expensive to ignore — leaky plenums waste the efficiency you paid for. We mastic-sealed every joint so the airflow the new system produces actually reaches the rooms.

“Our 25+ years old gas furnace ran into issues and we could have just replaced the part and limped along for a while. We decided to do a like-for-like replacement...we got a quote (I won't mention the name of the vendor) and got a quote for a Bryant a/c/ gas furnace (lower than the Carrier a/c that we had) and the quote was pretty high ~ $25K and NO REBATES (this person did not even offer us the option of a heat pump). Our son suggested going to Yelp to get a project quote given we were spending so much money - from the 8 companies we talked to we zeroed in on Irbis and NUR and both companies were solid. Our main reason for going with NUR were the following : 1) With NUR we dealt directly with the Owner not a sales team : David - he is a no-nonsense, straight shooter who is extremely knowledgeable about all things HVAC. 2) Offered the right spec and quality of machine - He told us we should go with the Heat Pump (replace gas furnace) given we had solar and he offered us the complex split zoning for our single family house. Upgraded our carrier a/c to a Mitsubishi Heat Pump (see picture) 3) Reasonable Quote, High Quality work - He offered us an extremely reasonable quote for a high end heat pump, his technicians were top notch. Igor and Mikhail were brilliant - they spent a week at our place and were so polite, skilled and unobtrusive. They cleaned up after themselves every single day that they came in. 4) Helped me get the $3500 rebate from Peninsula Clean Energy 5) After install customer service is brilliant. I am doing this review after a month but these guys are beyond amazing when it comes to responsiveness to any questions or concerns. If I do any replacement of my HVAC and water heaters in the future - I will not look beyond NUR - they have my business for life”
“We could not be happier with Nur HVAC. They installed 2 HVAC systems in our home and have been absolutely fantastic ever since. Whatever an issue comes up they respond quickly and get it fixed without delays. They are reliable, professional, knowledgeable and always willing to help. It's such a relief to have someone we can trust to take care of our home's electrical and HVAC needs. We highly recommend them to anyone looking for a dependable professional who truly stands behind its work!”
“This is not the first project I have done with this team. I would like to note the exceptional quality of installation, really low prices and excellent service.”
“I contacted David several times with orders of different levels of complexity. Always great quality. I highly recommend David.”

“I recently had the pleasure of working with Nur HVAC for the installation of a heat pump and AC system in my home. From the initial consultation with Fedor, I was impressed with their professionalism and expertise. They patiently guided me through the process, including navigating HOA approvals and securing necessary city permits and inspections. I was particularly pleased with how they handled the installation. Sergeii, the installer, demonstrated exceptional skill and attention to detail, finding creative solutions to the challenges posed by my home's high ceilings. He successfully installed the copper pipes in the roof, avoiding the need to cut into my ceiling, which was a major concern for me. Nur HVAC was also incredibly helpful in maximizing my rebates. They informed me about available incentives and even reminded me of the Peninsula Clean Energy deadline to ensure I received the maximum possible savings. Despite working during the intense October heat, their team maintained a high level of professionalism and meticulousness. They cleaned up the worksite thoroughly upon completion. This was my second home renovation, and I can honestly say that Nur HVAC is the first contractor I've worked with that has exceeded my expectations. Their expertise, dedication, and commitment to customer satisfaction are truly commendable. I highly recommend Nur HVAC to anyone in need of quality HVAC services.”
“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!”
“The team did a wonderful job installing our heat pump. The crew worked with attention and care, and was very respectful of the property. Excellent service: very timely, very thoughtful, very professional. Highly recommended!”
“I used NUR’s service to install a mini-split system, they were the best! The quoting process was easy and the price was fair, the installation team were very meticulous, professional, and they did a very clean job. Very happy with them throughout the work and the system they installed works great.”
“Working with NUR HVAC was an absolute right choice. From the very first visit, our point of contact Fedor was professional, courteous, and well informed. He answered all our questions about possible options for adding a second unit to our upstairs area, provided real world advice on practicality yet respected our desires for what we wanted done. He made it happen the way we wanted it, and we couldn't be happier. It was a breeze working with Fedor and the rest of the team. They were timely, speedy, and efficient all while providing reassuring quality in their work. HERS testing and City inspection were super quick with both commenting on the great quality of the work. Thanks Fedor!”
“Professional, excellent quality electrical work. Happy so far with large Mitsubishi forced air heat pump, small 2-head mini split heat pump, and Rheem heat pump water heater.”
“Islam was excellent. He was prompt and efficient. He identified the issues with the A/C system immediately. I strongly recommend Islam at Nur HVAC!”
“Great service. Professional stuff. So happy I chose Nur HVAC for HVAC installation and for maintenance.”
