Fuse HVAC, Refrigeration, Electrical & Plumbing

Wow, I am impressed. I usually get disappointed and frustrated when I deal with home-improvement contractors. A lot of companies claim that they are customer-focused and yet most of them can barely respect an appointment on time, respond to your emails/calls in a timely manner, or give you accurate information. With FUSE, it is the first time that I have dealt with a company that delivers on all aspects from the beginning to the end of my project, and beyond. I would definitely use them again. FUSE is a very organized company with different people responsible for different tasks. They are all well coordinated and all of them have been terrific for my project.

I hired them in September 2025 for my HVAC project: replace my gas furnace with a highly efficient air-air Heap Pump and redesign/replace the ducting system for my main house, as well as add a 2nd Heat Pump with a ductless mini-split for a small ADU.

Front-end. Russel was the advisor, who first visited my house to estimate the work. He answered all my questions, both on site and many times via email & SMS after his visit. He promptly updated my quote several times as I requested changes and additions, including some extra unrelated tasks. He also added the advertised discounts and the rebates I could qualify for (which many other vendors could not clearly identify). My very positive experience with Russel is ultimately the main reason I proceeded with FUSE.

- On-site work. Eugene was the lead technician and was helped by 2 other team members. The work was completed with high quality and on-schedule. Eugene kept me informed on their progress and involved me a few times when unexpected issues raised and a customer decision was needed. Eugene was competent, friendly and gained my trust. Even after the work was completed, he stayed responsive when I reached out to him as I faced an electrical problem a few days later. He visited back my house on the very same day with one of FUSE electrician, who identified the HVAC work did not cause it and still ended up addressing the unrelated issue in the panel (turned out to be trivial).

Handy man. In order to patch and paint the holes that were needed for the project, FUSE sent a handy man. Norah from FUSE did the scheduling and kept me informed of possible time change; FUSE also communicated accurately all the work that needed to be done by the handy man. Even though Eduard the handy man was sub-contracted and not a FUSE employee, he delivered a very high quality work as well and it was another very positive experience. Only possible improvement was that FUSE could not schedule this sooner (I had to wait 3 weeks after main work was completed).

Permit. The permit department coordinated with me to schedule the city inspection. They also promptly responded when I needed additional permit paperwork to submit my SVCE rebate application. On the day of the inspection, Alex was the FUSE employee that called me to ensure I would be home at the scheduled time. He showed up before the city inspector to verify everything was correct and guided the inspector, who congratulated him on the high quality work FUSE did. As I was chatting with Alex, I mentioned that some minor adjustment could be done with the dampers. Before the day was over, Norah reached out to let me know she will be working on scheduling of a technician for that. That's what I call being coordinated and following through!

Rebates. Maria was the rebates coordinator. She, too, was very responsive and properly submitted the Tech Clean rebate on my behalf. She correctly set time expectation with me and sent me the check promptly once she received it. The FUSE support team also promptly send me the additional invoice break-down I needed for the SVCE rebate. It was great to see how FUSE was supporting me in getting the rebate I could qualify for.

Over all, I am extremely satisfied of the experience I received from FUSE and I highly recommend them. Considering the valuable service they provided me, I am actually considering signing up for their maintenance plan.

We just got Fuse Services to install a new heat pump water heater. Our installer Wesley did an excellent job. His attention to detail was fantastic. He is methodical, making sure every component was installed properly. We’re very happy with installation. We’re glad to have found a reliable contractor for future projects.

FUSE Service technicians did a great job in installing a replacement gas water heater. FUSE supplied the water heater and had the extra parts on hand to complete the installation. FUSE arrived on scheduled time and completed the removal and installation just over 2 hours.
Quality work and happy with the results!

We had great experience with Austin and Wade for our HVAC heat pump installation, they were on time and professional.
There were some confusion about the installation but it was sorted out, they explained everything and cleaned all the debris.
We also installed HEat Pump Water Heater with Fuse

I contracted with FUSE to install a new water softener at my home (to replace a failed unit).

(+1 star):

I worked with a FUSE sales person, Viktor B., and we did a video appt to talk about my needs and see the area for install. He sent me an initial written estimate, but it was lacking some clarity. After some back and forth over email and phone calls, The estimate was updated and I was happy. But I was not even offered an option for a City Permit, even though the city of San Jose requires a permit for this. This tells me that FUSE must be doing most of its installs unpermitted, unless requested by customer. I asked Viktor to add the permit to the estimate and I approved it.

FUSE scheduling dept was quick to reach out to me to schedule the install after estimate approval. I asked if the city permit was pulled, and it wasn't. A permit needs to be pulled before starting work. I told them to contact me back after the permit was pulled, which they did, and we scheduled the install a few days later. I appreciate the quick turnaround time so far.

On the day of the installation, plumber Kirill S. and his assistant arrived on time. There was some unclarity about the scope of the work, but that was resolved after I showed Kirill the signed contract, and he also checked with the back office. I expected the technicians to arrive with a clear scope of work already. If I was not there, the install would not have been made according to spec. The install went smoothly and Kirill and his assistant was friendly but professional. I am happy with the quality of the install. I made the full payment the same day (as required), and was told I'll be contacted to schedule the city inspection soon.

Dealing with the FUSE permits department is a huge headache. They don't have a direct phone #, and emails take a long time to respond, if at all.

1. (-2 stars): A week went by after the install, and I was never contacted to schedule the city inspection. I called the main FUSE support line, and I was told my project was already done. Huh? I told them to look at the signed contract, to see the city inspection was still pending. Then I was assured someone from the permits dept would contact me. But they never did. I called nearly daily to inquire status update, but it didn't seem to go anywhere. I had to contact my sales person, Viktor, to press the permits dept to see what's going on. Finally a month after install, my city inspection was scheduled, for a month later! So 2 months from install. This was a huge waste of my time.

2. (-1 star): The city inspection passed and I got a copy of the signed permit. But not permit payment receipt to the city. When I emailed the permits dept asking for it, no response. I had to call in to support and have them rely. When permits dept finally got back to me, I was told it cannot be given due to "security risks". Huh? I asked again, and I finally got a copy and FUSE paid $316.19 to the City. Yet I paid $750 to FUSE for the permit. The difference ($433.81) I was told is due to "business overhead costs for licenses and insurance". Huh? The city permit is something I elected to add, otherwise, then I wouldn't need to pay for these "overhead costs".

Overall, I think FUSE did a good install. But I cannot recommend the company due to the amount of hassle I had to go through with the permits dept wasting my time (and money). A city permit should cost what is paid to the city, not more than 2x for "overhead". There needs to be more transparency.
