We removed the worn-out furnace and installed the new one in the same space, complete with fresh condensate drain lines, float safety switches and a properly sealed plenum — you can see the tidy PVC drain work in the photos. Everything was connected and tested so the homeowner has dependable heat all winter.
Why replacing an old furnace pays off
- Dependable heat — a new unit starts every time, so there are no cold mornings waiting on an old furnace.
- Better efficiency — modern furnaces convert more of the fuel they use into actual heat, which helps with winter bills.
- Safer operation — fresh safety switches and a clean install reduce the risks that come with aging equipment.
- Quieter comfort — new blowers run smoother and quieter than a furnace near the end of its life.
When a furnace starts needing repeated repairs, replacement is usually the smarter spend. We finished this Fremont furnace installation with sealed ducting and a full safety and performance check before handing it over. If your furnace is more than 15 years old, it’s worth planning ahead rather than waiting for a breakdown.
A fresh furnace makes a real difference in a Fremont winter — steadier heat, quieter cycles, and far fewer surprise breakdowns. We sized this unit to the home and tested it fully before leaving, so it is ready to run reliably from the first cold night.

Reviews
Trusted by your neighbors
“I needed help with water leak near the condenser unit and they came over only to find out the issue was not with the HVAC unit. I love the fact they spent explaining and helping with recommended next steps. And they didn't charge me the diagnostic fee. I would call them if I ever needed help as they seem trustworthy. I highly recommend them.”
“My dryer suddenly stopped working, and I also needed to replace an old Nest thermostat right before my cross-country move. On short notice, Nur Service was able to find the root cause of the dryer issue, fix it, and install the Nest thermostat all within an hour. Thank you!”
“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!”

“Alexey at Nur HVAC did an amazing job to repair my broken furnace. When it turned out that the likely problem indicated by the initial diagnosis was a false alarm, Alexey promptly identified the correct problem and came out on a holiday to fix it. This was extremely courteous of him as we were already struggling for over a week with no heat. But even after getting the furnace to pump hot air, the job was not fully done due to another component that needed to be replaced. To be fair to Alexey, it was a case of one fix revealing something else that was broken, and it took four visits (including the initial call) to fix everything. Throughout the process, Alexey and Regina were very prompt in answering questions and providing updates. They did not expect any payment until the job was 100% complete, and also honored the original quote, which speaks volumes about their professionalism. And their quote was already very reasonable compared to another company who quoted roughly 3-4 times as much. Overall I am extremely happy with Nur HVAC’s service and I highly recommend them.”
“Had an issue with water leak and I thought it was related to the HVAC unit. David and another technician came over and when they realized it’s not a HVAC related issue they helped with good recommendations in terms of next steps. They didn’t even charge me for their visit! Would highly recommend them!”
“Very professional service and high quality work. Fedor has alway been patently answer my questions and explain things in details, responding to me quickly even during weekends. Aleksandr and Aziz did a superior job installing a Mitsubishi heatpump system and replaced the entire duct system. I can see that they were very organized and also took care to keep things neat and clean. Highly recommended!”
“Michael was very helpful. He spotted the problem and got it repaired asap. Excellent technician!”
“Phenomenal Service – Furnace Replacement & Heat Pump Installation! I can’t say enough good things about the team at Nur HVAC! They recently installed a brand-new AC heat pump system for us and replaced our old gas furnace, and the experience was top-tier from start to finish. The installation was completed with incredible attention to detail, craftsmanship, and professionalism. They found smart, creative ways to route all the new wiring while opening as few walls as possible. For the couple of small spots where wall access was necessary, they made sure everything was fully patched, finished, and painted so seamlessly you’d never know any work had been done. On top of that, what stood out the most was their commitment to going above and beyond—they stayed late working extra hours just to ensure our Google Nest thermostat was fully integrated, tested, and working perfectly before they left. It’s rare to find contractors who are this reliable, clean, knowledgeable, and genuinely dedicated to customer satisfaction. If you need any HVAC work done, save yourself the hassle and hire Nur HVAC. Outstanding job all around!”
“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.”
“Excellent experience. We requested a routine furnace inspection and were able to be scheduled the next day with Islam. Islam was incredibly professional, thorough, and efficient. He did not try to upsell us on any repairs, and he even took the time to successfully troubleshoot why our attic light wasn't working (saving us an expensive electrical visit later on). If we need repairs or replacement in the future, Nur HVAC will be the first company we seek out.”
“Loved my technician. Very honest. He replaced my gas heater and AC unit. Turned out great. Gas furnace wont be available after next year. So this should last another 25 years before I have to upgrade my panel to support a heat pump product. Dodged a bullet. I recommend this company. Susan Lacy Municipal Construction Inspector”
“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.”
