    New furnace, mounted like it's supposed to be. Look at those pretty ducts!

    Noam is just an all around nice human. His team is caring and hard working and went overboard to make certain the job site was clean and put back together. They were done within two days and I was able to keep working while they were here! That's the overview. Here's the long story. I had a maintenance plan for our furnace through another company. They inspected the furnace and freaked me out when they said they couldn't do maintenance because of exposed asbestos in the ducts! Ugh! Even with my "special" plan pricing, their rate to remove and abate the asbestos (through a third party) and replace with new ductwork was very high. I saw All Bay and asked for an estimate. His team included removal, remediation, new ducting and insulation, new furnace - oh and cleaned the attic and installed new batting for the same price as the other company's quote. Plus the photos of previous work and their reviews sealed the deal. Done with all of it in two and a 1/2 days. The half was because they had a team that just cleaned and touched up behind the first team! These guys were so kind and worked fast. They even hauled out and disposed of some things a previous contractor had left in the crawl space without me knowing it was even down there! Then when we realized the fan in the bathroom wasn't working after the attic clean out and new insulation, the foreman himself came out to fix it. Pasquale had everything fixed within hours. If you're thinking of squeezing out another year with your old furnace, consider this - our PGE bill dropped by 100 with the new insulation, proper duct size and new furnace. That's 1200 in one year. Noam can help with that. He did not give me anything nor ask for any of this. This is for y'all doing your due diligence when it comes to home repairs. I feel you and it's been constant contractors in and out since we moved in. This team cared and I can't say that about many of the others.

    Main point: maximum value through All Bay Insulation & HVAC - Noam cares about the quality and thoroughness of their work, communication was on point and timely, and I highly recommend them. 4/29/25: Reached out via Yelp 5/1/25: Noam (the owner) came by and provided an incredibly competitive and generous estimate to install new insulation in our attic (~$2000 less than other estimates I received). He showed me pictures, and, as it turns out, the service we used to rodent-proof our house two years ago (after a couple of unwanted guests came into the home) did NOT do a great job in clearing out the old insulation and sanitizing the space. I signed on the spot, and cleared my calendar for the next day. Noam said that they were going to also clean out all the air ducts in the house, and put additional insulation around the air vents and above my 13 month old's room (which is vulnerable to hot and cold temperature fluctuations.) 5/2/25: Insulation came at 7AM. R38 Ecobatt (which, from my research, is the premium standard for insulation). 8:04AM: Team (Noam, Marcelo, and Divan) arrived an hour ahead of schedule. They took great care in protecting the house with liners (we have a 13 month old at home, so this is important). 9:02AM: After an hour of prepping the house, they got to work in cleaning the attic, and they found asbestos, which luckily, they were certified and trained to remediate on-site and on the same day. 2:45PM: Team was done (15 minutes before expected). The morning after: our home feels incredibly insulated. The heat never kicked on, and the temperature inside the house never moved from 70 degrees all night.

    I was dealing with really bad allergies every time I turned on the heat, and I started to suspect it was coming from dusty air vents. After some searching, I reached out to All Bay Insulation & HVAC, and I'm so glad I did. I called Noam (the owner) on a Wednesday, and he and his crew Cande came out promptly--actually arriving early and ready to get started. From the moment they arrived, they were professional, knowledgeable, and incredibly patient in answering all my questions. They took great care of my home--wearing shoe covers, taping down the kitchen area, and keeping everything clean and tidy throughout the process. They thoroughly cleaned all the ducts and bathroom vents, and even went above and beyond by cleaning the dryer vent at no extra charge. What really stood out to me was Noam's honesty. He pointed out that a section of my air duct had been squished by someone who had previously been in my attic, and instead of upselling me, he told me it was an easy fix I could handle myself for about $10. It's rare to find someone this trustworthy, detail-oriented, and respectful. I highly recommend Noam and his team--great service, great people, and a genuinely positive experience from start to finish.

    Had my old ductwork replaced by All Bay, including new insulation and vapor barrier in crawl space, and they did a fantastic job. Communication was excellent throughout, especially with the owner Noam, who was responsive, knowledgeable, and hands-on. The whole project took about 5 days, and the team showed up promptly every day. They were professional, efficient, and left the place clean and tidy once the work was done. While the price wasn't the lowest, the quality of service, care, and peace of mind made it well worth it. Noam explained that as a licensed general contractor, he's certified to remove a certain amount of asbestos. Just to be extra safe, I hired a third-party air testing company before he continued with other work - everything came back clear. During a walk-through, I pointed out areas that needed rodent-proofing, and Noam had his crew reinforce them right away. Since the replacement, there's been a noticeable improvement in overall home comfort - better airflow and more even temperatures throughout the house. Highly recommend if you want the job done right, with great communication and follow-through.

    We first worked with Noam and his team in 2019 to install insulation and a barrier layer in both our crawl space and attic before moving in. From the start, we were extremely impressed by the quality of their workmanship and attention to detail. When we undertook a renovation in 2023, there was no question about who we would call - Noam and his team installed a new heater and A/C unit in our attic with the same professionalism and efficiency. The project was completed on schedule and exceeded our expectations. More recently, when we encountered a rodent issue in the attic, Noam responded immediately and provided assistance free of charge as a courtesy. This level of customer care truly sets them apart. If we have any future projects, we will definitely turn to Noam and his team again. We highly recommend their services to anyone looking for reliable, high-quality work delivered with integrity and excellent customer support.

    We have done all the duct pipe replacement and insulation from The All bay back in 2022. They have been doing a phenomenal job. They came even in 2025 to check on the rodent activity. Irving Herrera was a gem of a person. Truly professional. He did the job perfectly, and after that, I have not heard any rodent activity. He sealed the room on the second floor. He came again since he did not have a big ladder. I would highly recommend their service.

    Does this company recommend/use the ECO Batt insulation?

    Eco batts insulation is great it’s made out of recycled materials with reduced amount of fiber glass it doesn’t have a color nor smell and has high acoustical value. Great for noise reduction.

Unlike some other companies that focused only on the attic, Attical inspected the entire property, including the attic, crawlspace, garage, exterior walls, roofline, and other potential rodent entry points. They identified and sealed areas that other companies either overlooked or never mentioned. Their pricing was also very competitive. During the quoting process, some companies adjusted their pricing based on estimated labor time, crew size, or changing measurements. Attical, on the other hand, honored their proposal and focused on getting the job done properly rather than finding reasons to increase the price later. Throughout the project, they delivered exactly what they promised: insulation removal, sanitation, rodent proofing, air sealing, duct repairs, trap monitoring, and new insulation installation. The crew was professional, hardworking, and took the time to explain the process and answer questions along the way. Overall, I felt that they genuinely cared about solving the problem correctly instead of simply completing another job. I would highly recommend Attical to anyone looking for attic insulation, rodent proofing, or attic restoration services.
