I highly recommend NUR HVAC to install or replace your old system. We had our 2 HVAC systems replaced with heat pump systems. Since we have solar installed on our roof, we opted for the Carrier heat pumps and new air handlers which don't use natural gas for heat. Their installers were always on time and cleaned up after each day of work. They arranged for the permit and scheduled final inspection. A very nice job and respectful staff!!

I am happy to do business with Nur HVAC. They have an excellent phone service. Regina, who I talked to on the phone regarding my central heating problem, and she was very courteous, and helpful. Adlan did a thorough job to make sure that my central heating system worked properly before he left. I am very happy with their services. Thanks guys for the great service you have provided to me. Keep up with your great work

I've worked with Nur multiple times, specifically Fedor and Alex. They do a great job and are thorough. It's great to be able to switch from a gas furnace to a heat pump, which means we have A/C now too! They also installed a new thermostat and put more insulation around exterior ducting. They reply quickly and are polite. I've also seen them doing commercial HVAC systems so they are trusted by businesses too.

Nur HVAC was very easy to communicate with and professional. Hugh praise to technician Adlan, who is knowledgeable and familiar with our apartment building. He promptly fixed the ac issue the same day as the diagnosis and went above and beyond to also help with the heating issue on a follow up visit. Would recommend this company to anybody in the bay area looking for hvac help.

I found this company via Yelp a few days ago. They responded immediately to my needs with clear communication and prompt scheduling through Yelp messaging. This morning, their tech alerted me 30 minutes before arrival and completed the repair within an hour, diagnosing the issue and error messages. I needed to replace my thermostat (which was an old Honeywell approximately 35 years old!) They installed a new Honeywell and it's working great.

Called because my commercial AC stopped blowing cold air. Was able to get an appointment for the next day. Got a message that Islam was en route. When he arrived he was very courteous and was able to change out the capacitor and get it working right away. Prices seemed fair, as well. I will definitely use them in the future for repairs and maintenance.

NUR replaced my very old AC with a new heat pump, and I am very pleased with their work. Their attention to detail stands out. The project manager, Fidor, communicates clearly about options that I have, and the engineer, Shilai, is skilled and hardworking. They care deeply about doing things the right way, not just getting the job done quickly. They replaced sections of piping that could affect system quality and relocated equipment to make space for the new unit, without additional charges. The insulation and pipe organization are professional and precise. Comparing side by side the new equipment installed with the old crap that the house had previous, you can easily tell the difference in quality. I appreciate how they handled the small things like removing old nails, tidying cables, and keeping the installation clean and well-organized. These are not required steps by code or in job description, but they did them anyway because they take pride in their work. They also avoid putting unnecessary ugly stickers on your equipment, which is a bonus. They may not focus much on sales presentations, but their workmanship speaks for itself. As an engineer myself, I value their straightforward, high-quality approach.

Nur HVAC installed a dual-system heat pump for us (unit on the ground floor and another upstairs) a few months ago. We would highly recommend them for the quality of work at a competitive cost. The system has been working very well.

I do not review many companies. However, NUR did such an exceptional job installing a heat pump at my house they rate a compliment. The installers were diligent, neat, on time and polite. They solved several installation problems. An excellent company to get a heat pump from. Chris
