Later that evening, PG&E confirmed that our furnace had failed and was releasing carbon monoxide into our home. The next morning, I began calling HVAC contractors. None of the nine companies I contacted could help for at least a week. Fortunately, a friend from my daughter's school referred me to Jose. He answered on the second ring, immediately understood the issue, and told me his Vice President would be at my house within the hour. Just 30 minutes later, Rudy arrived and quickly confirmed the diagnosis with his equipment. Jose immediately recognized the urgency of the situation. Not only were we without heat in freezing temperatures, but our family was also at risk of further carbon monoxide exposure. By 5:00 p.m. that same day, Air Flow Pros had sourced and delivered a new furnace, assembled a six-person crew, and begun removing the old unit. By 8:00 p.m., the new furnace was professionally installed, the work area was spotless, and our home was once again warm and safe. The service was truly outstanding. Air Flow Pros delivered a high-quality product at a fair price and completed the entire job within eight hours of my initial call. I couldn't be happier and would recommend them without hesitation.

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!

But if you are looking for a partner to…read moretransform your home into a safe, efficient, and future-proof sanctuary, there is only one name: Fuse Service HVAC & Electrical SF. Our journey with Fuse didn't start with a grand vision; it started with one project. But excellence has a way of building trust, and that trust led us to a total home evolution. Reliability That Weathers the Storm (and the Heat) Two years ago, Fuse installed our HVAC system. Today, as we navigate a punishing heat wave, that system isn't just "running"--it is performing with surgical precision. For us, this isn't just about comfort; it's about care. We have a senior in our home, and the ability of the Fuse-installed system to regulate temperature flawlessly provides a level of peace of mind that you cannot put a price tag on. When the world outside is scorching, our home remains a cool, consistent haven. The Great Transition of 2025 In 2025, we decided to step into the future. We tapped Fuse to retire our decades-old gas water heater in favor of a high-efficiency electric heat pump. To power our new lifestyle, we also needed to upgrade our electrical backbone from a 100A to a 200A panel. This is where Fuse truly separates themselves from the pack. Their teams didn't just work; they worked tirelessly. They orchestrated the entire symphony of the upgrade, including the complex coordination with PG&E. (A shoutout to PG&E as well for their seamless cooperation!) Fuse handled the bureaucracy and the heavy lifting, leaving us with nothing to do but watch our home modernize before our eyes. A Legacy of Safety and Sustainability Today, my home stands as a testament to what is possible. We are now fully electric. No more gas usage. No more carbon footprint from fossil fuels. No more Carbon Monoxide (CO) concerns--ever. There is a profound sense of liberation that comes with cutting the gas line. We have eliminated a silent invisible risk, replaced it with clean technology, and ensured our home is ready for the next fifty years. The Verdict If you want a company that shows up, you can call anyone. But if you want a team that works with integrity, masters the latest technology, and treats your family's safety as their own, you call Fuse. They don't just fix houses; they empower homeowners. Don't wait for your old systems to fail. Step into the future. Call Fuse. You won't just be changing your appliances; you'll be changing your life.

Long overdue review for James and his Team!…read more I had hired them a few years back based on their reputation and excellent Yelp reviews for a furnace installation & ducting in my own home and they did an awesome job. Great communication, workmanship, and efficiency. They were first to come to mind again when I recently needed another old furnace replaced in a commercial tenant's space. Time was of the essence and James accommodated us into his busy winter schedule within two days. Since the furnace was very old and ducting was from another era, James communicated right away all of the potential issues. His team even stayed late to complete the install in the same visit so the tenant could have warm air right away. Any unusual or other issues that arose during the install, James communicated and had resolved as soon as possible to ensure client satisfaction. I am very picky when it comes to professional building techs, but would give 10 stars to Ocean Air if I could. My only disappointment is that they do not have a plumbing, electrical, or general building maintenance arm of their business!

What bothered me most was that when I questioned them, their explanation kept changing. First it was the compressor, then an "open line," then a high-voltage breaker issue. That is not a diagnosis I can trust, or a diagnosis based in true process of elimination testing to arrive at the core issue. I've been running a restaurant for nearly 20 years, and I've seen this pattern many times before: jump straight to the most expensive repair. In my experience, this felt like either incompetence or an attempt to oversell a job that wasn't needed. I will never use them again, and I strongly recommend getting a second opinion before approving any HVAC work from Next HVAC.

During the estimate phase, Constantine was a breath of fresh air. Instead of pushing generic upsells, he actually "downsold" us by engineering exactly what we needed to work seamlessly with our home's downflow ducting. He was honest, straightforward, and clearly explained the system without any high-pressure sales tactics. For the installation, Mike and Diego were our crew. They arrived a little past the initial 9am window on the first day, but they worked incredibly hard and got the entire complex job done right on schedule. At the start of Day 1, I handed them a simple "homeowner's QA" list of things I wanted to check with them at the end. They were super nice, listened, and gladly accommodated every single request. The workmanship is top-notch. They perfectly sealed the exterior wall where the lineset exits, helped me get the Kumo Cloud Wi-Fi connected to my phone, and hauled away all the old debris, leaving the site spotless. As a testament to their technical skill, when I asked about the refrigerant line vacuum test, they had pulled it down to 350 microns--which is a great number and proves they don't cut corners! Pics attached of the final setup. If you want an HVAC company that is honest in the office and expert in the field, we highly recommend the Galaxy team!
