Heating, Cooling & HVAC in Los Altos

“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.”

“I’m very happy with my new heating-cooling heat pump system, which ties in to my existing ducts, is energy efficient (using electricity rather than natural gas), and keeps my furnace as an alternate option. I called several companies asking for quotes on something else - a whole house fan - and NUR had the fastest and most professional response. Technician David came out and explained several options to me. He said we could try just an attic fan and that alone may cool my home enough. He gave me a quote for that, and also for a whole house fan, and a heat pump. He explained what each option would and would not do. I decided to go with the heat pump heating/cooling along with an attic fan. Even though it was the most expensive choice, I think as time goes on and our climate gets warmer, AC will become even more expensive and hard to get. INSTALLATION: The installers, Artur and Vlad, were polite and considerate as well as competent and hard working. The installation was complicated, including drilling and hammering throughout the crawl space running under the entire house, and completely taking apart and putting back together my furnace. After 2 days I had AC, and after 2 more days I had the attic fan, heating, and was ready for inspection. CUSTOMER SERVICE: After the job was completed and I had paid, I had a few questions, and David responded immediately and said to call anytime questions come up. So excellent customer service before, during, and after installation. RESULTS: I’m thrilled with this home improvement, which adds value as well as comfort. Very glad I chose NUR HVAC, and highly recommend them.”

“Very competent, quickly diagnosed that the issue was a thermostat whose rechargeable battery was no longer holding a charge. Other companies were trying to have me replace the furnace (a much bigger expense). Our furnace is old and will need replacement sooner rather than later but the furnace wasn’t the issue. Glad that Islam from Nur HVAC was able to quickly identify the real issue. Great experience overall and I’d recommend them to anyone needing HVAC work.”

“Our old A/C unit went out (dramatically spewing coolant everywhere) in the middle of summer. We contacted Nur HVAC and got them to come take a look at the situation. They recommended replacing our old furnace with a new heat pump along with the new A/C unit. It took a few weeks for a permit, but then they scheduled the job promptly. It was very labor intensive...removing the old equipment, building a new platform with plywood, installing everything. It took 3 full days, but they did an excellent job and cleaned everything up completely when they were finished. The system looks and works so much better now. Workers were polite and respectful. Would definitely recommend.”

“Summary: great value, high quality install that paid attention to details, owner and employees listen to and value customer feedback, clean work, high integrity business, responsive and communicative Normally one would not describe their heating and cooling equipment as a work of art, but I hope to change your mind after describing how Fedor, Aleksander, David, Artur, and the rest of Nur HVAC did an impeccably beautiful install of a new heat pump and new ductwork, removal of old gas furnace, and removal of old asbestos ducts. Throughout the process, they made me feel like a highly valued customer. I would recommend them with zero hesitation to anyone looking for an honest and diligent HVAC contractor that performs top-notch work. [Sales experience] I shopped around various HVAC contractors on Yelp, and I was fortunate to have Nur HVAC respond. David, the owner, came out to give me a quote, and I immediately had a great first impression of him and Nur. David was highly knowledgeable in HVAC, and he listened to me and what I wanted as opposed to trying to push me a hard sale. David is a rare gem in the HVAC industry, where instead of trying to upsell every chance, he actually thinks about what is needed, what's a waste of money, and he conducts himself with the utmost integrity to give the best recommendation for me and not his own pocketbook. The integrity and honesty of Nur is seen when they automatically included permits and HERS testing in the quote. I continued conversing with David, and he would always respond quickly and professionally. At the end of the day, Nur came in with a very competitive bid, and it was an easy decision for me to choose them because of the rapport I developed with David. [Install experience] My install team was Fedor and Aleksander, and I cannot overstate how awesome they were. They showed up punctually every day at 9am in the morning and worked until 6pm in the evening until the whole job was completed. The pride that they took in their work is immediately apparent: the work was not rushed, no corners were cut, they made sure to do everything right all the way down the finest details, and they made sure to clean up every small speck of dust and dirt. For example, when putting in the new vents: they applied several sealant coats inside the vent box to make sure that the ductwork would not leak conditioned air to increase system efficiency. When they finished, they cleaned my attic and made it spotless. Fedor and Aleksander entertained my curiosity in the work and were more than happy to take my feedback and requests, which is further evidence that they actually enjoy the work and have a customer-first approach to their job. For example, there was an audible humming heard inside the home when the outdoor unit was first powered on, and they quickly acted on my observation to add vibration dampening materials that made the noise go away. While making small talk with Fedor, I learned that he used to work in the HVAC industry before he came to America, which explains the expertise and perfectionism that he brought to my job. If you end up working with Nur, I unequivocally recommend you to request Fedor and Aleksander to work on your job, you won't be disappointed. [After install] Kseniia and Chinaza from the office ensured that the HERS tester and city inspector, who are third parties not affiliated with Nur, could be scheduled around my busy life. The HERS tester showed up on time, and he finished the HERS test within 30 minutes and told me that everything looked great. After this, Nur set up the city inspection so the permit could be finaled. Artur arrived on inspection day, and he helped ensure that the inspection process would be completed smoothly. The city inspector commented on how well done the install was, and he only had effusive praise for how well done everything was: the ducting, the air handler, the outdoor unit, the condensate line, and even how clean the attic was. On top of all of this, I am saving money on my utility bill!”
