Carrier furnace repair in Half Moon Bay: draft inducer and PVC exhaust
Two days after a furnace service call at this home in Half Moon Bay, we came back for a follow-up visit. This Carrier furnace repair was about the parts of a high-efficiency furnace most people never think about: the draft inducer motor and the white PVC pipe that carries exhaust out of the house. The furnace is a two-stage high-efficiency unit tucked into a narrow hallway closet, with the vent running up through the attic.
What we worked on
On a high-efficiency furnace, the draft inducer is the small fan that pulls combustion gases through the heat exchanger and pushes them out through the PVC exhaust. If that motor or the pipe behind it isn’t in good shape, the furnace’s safety controls won’t let it run the way it should. So on this visit our technician:

- cleaned the draft inducer motor
- cleaned the PVC exhaust line
- reconnected the PVC exhaust
- did a full maintenance on the two-stage furnace

With the panels off, everything is easy to reach and easy to check. You can see the meters hooked up here — after cleaning, we test the furnace while it runs instead of just closing it up and hoping for the best.
Up in the attic
The other half of the job happened above the ceiling. The PVC exhaust leaves the closet, crosses the attic between the rafters, ducts and insulation, and heads for the roof. That route is where we did the reconnection.
Attics in older coastal homes are tight, and this one was no exception. Our tech worked his way along the pipe so the whole run could be looked at, not only the easy-to-reach end near the furnace.
Here is a closer look at the far end of the run. The blue primer on the fitting and the metal strap holding the pipe are part of putting the exhaust back together properly — PVC joints have to be clean, primed and supported so they stay put.
Back together and running
Once the attic side was done, the furnace was closed up again in its closet. The whole visit took about two hours, from opening the cabinet to the final check.

We like follow-up visits like this one. Going back to finish the job and look at the whole system — motor, vent and furnace together — is how a heating problem gets fixed instead of patched. Half Moon Bay winters aren’t harsh, but the damp, cool nights make a furnace you can trust a real comfort.

“We used Nur HVAC to replace gas furnace with a heat pump inverter, replace the aging duct work and gas water heater with a heat pump water heater, all in the same contract. Our project manager, Arthur was on-time for the scoping appointment. He took time to understand our needs, investigated the attic, ducts and all the existing equipment, before making any recommendations. He designed the optimal system for our house to be cost effective, provide highest comfort and be energy efficient. He was not pushy and was upfront about the ballpark estimates and timeline. He also walked us thru the various rebates that are available for the replacements from local utilities. Arthur's quote was very competitive, in fact better than those quoted to us by Costco referred contractors. Nur's installation crew - Eldar, Bhakridin, were very professional and thorough. They didn't rush the job and left the job site clean and clutter free each day. They accommodated our requests for placing the electrical wires and conduits so they are not in the way. All the equipment both indoor and outdoor were cleanly laid out, secured and wiped down before hand off. Always smiling and respectful, one of the best installation crew we have had. As a white glove contractor they took care of all the permitting, inspection paperwork w/ the city, all the paper work for us to receive the rebates. They even completed the warranty registration with the manufacturers for all the equipment! We would highly recommend Arthur and Nur HVAC to anyone in the Bay Area needing heating and cooling solutions. We would definitely be going back to them ourselves when the need arises.”

“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!”

“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.”

“Nur installed and serviced our heat pump since the beginning of 2025. Quality of work, including the air handling, heat pump, ductwork, piping and electrical work was excellent. There were communication issues with the field crew but were ultimately resolved. Only with the recent warmer weather I used the cooling stage (instead of the heating) and came across a problem where it wasn't cooling fast enough. Artur A. came back, checked all the vents and adjusted the air handling speed so it cools down much faster. Nur was responsive and fairly quick to correct our concerns. They were also quick to return and service our cooling issue. Thank you David and Artur A.”

“This will be my 2nd 5-star review for NUR HVAC and specifically for the work that Adlan provided with installing a new furnace in my Mom's house. This was a follow up review to my first one where he saved the day in fixing my mom's ancient furnace. This one is to really provide value and context with the exceptional work Adlan did in working his magic yet again in getting the job done so efficiently and creating such an easy/seamless experience with the installation of the new furnace. I truly commend his time, effort and overall expertise to ensure everything was installed with the highest level of precision. He is meticulous in his work and I am beyond impress with his professionalism and kindness. He again walked me through each of the new features and provided guidance on what to look out for and the maintenance needed (which was very little with everything being super new). We now have a great new Carrier furnace and a cool Ecobee Thermostat that is super user friendly and modern. If you get lucky enough to have Adlan on your service call, then just know you hit the jackpot in someone who truly cares about his work, is super diligent and is dedicated to providing you with 5-star customer service. Thank you Adlan for everything and for NUR HVAC for being such a great business to work with. The communication provided from start to finish is top notch and the whole process was amazing! I highly recommend them especially if you need anything done for your furnace, AC, HVAC needs. Put them on your speed dial now, you will not regret it! =0)”

“After 18 years our Air Conditioning System failed. We, of course, called Nur HVAC and were glad to see Islam again. He rapidly diagnosed that the AC compressor failed and had to be replaced. However, the AC system was so old that the compressor only had a 1 year warranty and the refrigerant in use 18 years ago is only available for legacy repairs (This is to protect the Ozone layer). We could have replaced the AC system, but the heating system was equally old and likely to fail. The cost to move to a full all electric HVAC system was a few dollars more than just replacing the AC system and it would eliminate our use of gas for heating and take advantage of the recently installed Solar Panels. So the house has a new fully electric HVAC system installed by Nur HVAC. Islam came and took the measurements so the system could be ordered and priced. Soon Alex and the installation team arrived to install the system. The quality of the installation and the care Alex and team took during the custom wiring, new refrigerant lines, new moisture drains, new thermostats, system setup and calibration was outstanding. Alex made sure that the air flow for both heating and cooling was measured and far better than the previous systems. Alex made sure to keep us informed as progress was being made and they managed to keep the house clean during the install. Again Nur HVAC exceeded expectations with a very high quality install at a fair price. A project of this size had a few bumps but this appeared to have been done to provide a quality install with attention to detail. This company has superb knowledgeable professionals working for it from service to installation. I highly recommend Nur HVAC.”
“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”
“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!”
“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.”
“I highly recommend Islam from Nur HVAC to anyone needing reliable AC work. My AC went out and I had three different HVAC companies come by to look at it. None of them could fix the problem, and one company tried to tell me I needed a whole new zone board and two new dampers for several thousand dollars. Islam came out, listened carefully to everything I told him about what the previous technicans had said, and then did his own thorough troubleshooting. It was over 90 degrees out, and he spent time up in my hot, tight attic crawl space inspecting the indoor zone system and checking the outdoor condenser. He kept me updated the entire time on what he was testing and finding. Through his diagnosis, he proved that my dampers were actually working fine and that only the zone board needed to be replaced. Before doing any work, he gave me a clear quote upfront that came out to hundreds of dollars--saving me thousands compared to the other company. He installed the new board, double-checked that all the zones, thermostats, and dampers were working properly, and didn't leave until the system was running cold. Islam was punctual, polite, honest, and extremely hardworking. If you want AC work done right with technical competence and transparent communication, ask for Islam at Nur HVAC. I'll definitely be hiring him again.”
“NUR HVAC just completed installation of a Mitsubishi heat pump system in my San Francisco home, replacing a 38-year-old Lennox gas furnace. I couldn't be more pleased with the quality of the work and the professionalism shown during the process. In particular, I wanted to commend Artur and Vladimir, the NUR technicians who did the beautiful install. Both guys were extremely polite and respectful, for example, putting on shoe covers whenever they entered the house. Artur was also very fastidious in running the ancillary electrical feeds to my main service panel. What a neat job! Fedor, who came to do the initial assessment, was a great resource and answered all my questions regarding scheduling, warranty, maintenance, etc. He offered several options during the bidding process without any pressure to come to a quick decision or attempts at “upselling.” In the end, their quote was very competitive, and fair given the quality of the work and the final product. Being a Mitsubishi Diamond Contractor, NUR was able to offer a 12-year warranty on parts and labor. The bottom line is NUR is a top quality outfit and it was easy to see that they take great pride in their work and genuinely care about their customers. NUR may be the best contractor I’ve ever used. Definitely, 5-Star!”
“I had an old furnace replaced with a new heat pump and air handler. I was impressed by their initial on-site inspection: the representative noticed that the new air handler would be wider than the existing one, which would require that our water heater be moved several inches for clearance. No other company noticed that. Overall, communication was excellent. They answered all questions and provided the city work permit application number so I could track approval process with the city. Work went smoothly and was finished in a few days, much sooner than what I had anticipated. Very good experience, would recommend to anyone.”
