Recommended Customer Reviews

Fuse HVAC is outstanding. Right at the start, Logan went above and beyond with helping with availability options for assigning a tech for our HVAC repair. Once booked he even managed to pull the repair to be a whole day earlier than originally scheduled! Our assigned tech, Zaur, was punctual, professional, friendly, meticulous, and a true expert in his field. He was able to diagnose the issue, suggest the fix, already had the parts, and got us up and running again ahead of the next heat wave. Can truly trust Fuse HVAC for your repair needs!!!

Our gas tank water heater leaked and had to be replaced. We found some plumbers who would replace the same type water heater within a couple of hours.
However, I wanted to go electric and/or tankless with latest technology and wifi capabilities. I reached out to Fuse for electric water heaters and wanted to see if my 100 amp home (with no spare breaker slot) would support anything.
Konstantine from Fuse showed up same day for a free consult and convinced me to go for Heat Pump Water heater, which is electric and uses heat pump technology. He even did a rough load calc and said our home would pass the city inspection and they'd take care of all the city formalities.
These water heaters are super expensive ($3k+ for just the equipment), however there are a good chunk of rebates and tax benefits going on, dropping the effective price (including install) to below the gas water heaters. I was concerned about rebates, but Konstantine was confident and said there is no doubt about getting it approved and pointed me to all the online rebate resources to confirm.
I took the chances, got a the latest equipment installed, is wifi capable and Fuse Team also worked on getting the inspection approved by the city.

To put this review into perspective, I live in a condo building from the 1960s. In early January of this year, my gas furnace broke. The furnace was museum fodder: it was probably as old as the building itself, covered in asbestos, twelve inches wide, and stuck in a closet not much wider than that.
I run very cold, so this was an awful experience. But you know what was even more awful? Trying to find an HVAC contractor who could help me. Most of them said my furnace was completely dead, no modern furnace could fit in the existing closet, and the closet couldn't be expanded since it contains a flue that spans the entire height of the building.
- The first contractor told me I would never have heat again and my entire building was doomed. When I asked about a heat pump, he said it was ""impossible""
- The second brought up the idea of a mini-split heat pump, but never followed up
- The third said a mini-split would be too challenging and I should just get a wall furnace
- The fourth also said a mini-split would be too challenging. This contractor was at least willing to look into a very tiny gas furnace from Canada that I found online (the Dettson Chinook Compact). However, he said his company wouldn't be able to source this furnace for me
At this point, I was seriously about to give up. Then I found Fuse Service. From the start, they were prompt and professional.
- Frank, the estimator, said his team could source and install the Dettson Chinook Compact for me, but it would require new PVC pipes. Due to the amount of work involved in replacing the existing ductwork with PVC pipes, he recommended I opt for a heat pump instead, since it would be a better solution for both heating and cooling.
- Slava and Teodor, the project managers, figured out a design for a ductless mini-split system that involved placing the condenser on the rooftop, connecting the condenser to the mini-split units through the crawlspace, and then draining the condensation under my bathroom sink. They were *incredibly* thorough -- they calculated the electrical load based on my existing appliances and submitted paperwork to both my HOA and the City of San Mateo. I was pleasantly surprised by how fast they got the permit as well.
- The installation went remarkably smoothly. I was nervous since this was my first home improvement project ever, but all the Fuse technicians were incredible. Bolt and Paul, the HVAC experts, installed the entire mini-split heat pump in just three days, which is much less time than I expected for such a difficult project. Anatolii and Vlad, the electricians, installed a brand new and improved electrical panel on day 2. They all demonstrated amazing craftsmanship and attention to detail. In addition, they were also very considerate -- they laid down drop cloths to protect my floors, wore shoe covers, and cleaned up at the end of each day.
- The Fuse team in general sent me helpful text messages and emails to confirm my appointments. Their text messages about the technicians were fun: they had photos and blurbs about what the technicians like to do outside of work.
- After the installation, they also sent me a cute report about my new system, complete with pictures!
My new mini-split heat pump fills me with joy. Words cannot describe how wonderful it feels to have such a beautiful system in my home after months of being cold and hearing nothing but bad news from other HVAC companies. Thank you, Fuse Service!!!

I have a water heater leak and after looking around for options, decided to take advantage of various rebates and tax credits to replace the natural gas unit with an electrical heat pump. Fuse was one of the two companies listed on BayREN vendors which I can use to apply for their rebates. The total prices are quite a bit higher than if I were to hire individuals to install new heater and perform electrical upgrade needed. However, I may not have been able to apply for the rebates because a couple of the rebates have to be initiated by the installer. The 2nd companies which offered to deduct rebates upfront also come lower in total price but unfortunately there was a wait time of two weeks while Fuse was able to replace my heater within a few days. It was in the middle of Winter so not having hot water was quite inconvenient.
Although it took several months, I finally received all the rebates promised. Madina the rebate coordinator was very patient and courteous along the way, making sure all documents are filed correctly.
I would have taken a half star way if there is an option from this experience is that the electrician who showed up the day decided to pull the new circuit from my sub-panel instead of my main panel. This was different from what they said and recommended initially when they came to give me the quote. The distance for the circuit became significant, and much less work to do and the cost should have been at least a couple hundred dollars lower. Also, it took away a couple of precious slots in my sub-panel which I wanted to safe for EV charger in the future. When I asked about that, he said I could use a new type of 30A breaker which takes only 1 slot. But he installed the 2-slot breaker anyway and told me he didn't bring the new type of breaker which he suggested using. Also, he told me he was going to install fuse box on my outside wall at sholder height but didn't not tell me the fuse box came with a fairly long conduit exposed outside too. I wish all these can be concealed better with the fuse box placed somewhere else.
Another could be issue was that the young person from FUSE who showed up to meet the county inspection seemed inexperience. The inspector almost didn't approved the installation. But the inspector was nice and patient enough to go through the installation manual with me and finally found some exceptions mentioned in the manual allowing things to pass. The FUSE representative however did not provide much advice during the process.
Other than these minor issues, overall FUSE did a fine job with the water heater installation itself, and I am glad I went ahead switching to Heat pump. The wireless feature also allow me to control temperature remotely and watch for energy usage instantly. I would use and recommend FUSE again for similar jobs. My friend also went with FUSE for their heat pump upgrade after I passed along their info.

The pilot light of our water heater was out. We followed the instructions and tried a couple times to relight it. But it went out again once the button was released.
PGE tech came over and told us to replace the thermocouple. He also said it would be an easy fix.
I watched YouTube for hints and figured we probably needed a professional.
Enty from Fuse came to rescue. The first visit at noon confirmed it was a thermocouple problem. But there is no spare part handy. He got the part later on and came back at 8 PM after finishing 5 jobs on that day. Finally we had hot water again after taking cold showers in the last two days!
Enty is patient and would take time to get the job done right. As he started his day at 8 AM, we really appreciated his help after a very long day.
One more thing is that Fuse is willing to offer discounts. That makes the choice even easier.

Excellent service for 2 projects: 1) installation of a heat pump water heater and 2) repair of heating system duct break in crawl space under house. Both jobs were done on time, efficiently and with full clean up. Andrew K was the main fellow for #2 and did a great job under very difficult conditions in the crawl space. I will be recommending this company to friends and am happy to share this experience here.

I'm upgrading the rating to 3 stars, because the installation was completed on schedule; the techs did work very hard while they were on site; and they cleaned up fairly well at the end of the project. Only wished they were more communicative and had explained how the installation was to progress at the commencement of the project.

Our landlord got this company to fix a completely broken hydronic heating. Andrew K. came the same day for diagnosis and the guy seemed really competent; checked all the wiring and was able to tell us exactly which parts were broken.
For the replacement with a heat pump, Oleg R. and his colleague did a fantastic job under really difficult conditions in the house (heating in the attic, very narrow entry etc). They really knew what they were doing and just made it work. They also made an effort to not leave any dirt, which we really appreciated.
The heating works super well now. I can recommend these guys, especially in comparison with another company that the landlord had tried before.

My furnace stopped working on Friday. I reached out to trusty Fuse service who previously performed quality repair on my dryer and installed a faucet during kitchen remodel. On Saturday morning, Zaur came out to my house at 8 am and within the hour he diagnosed the issue and fixed the furnace. He replaced the faulty igniter and now I again have a warm house for my family. Zaur, and Fuse services, thank you for the awesome quality and quick repair.

Received great service from Vitalii, the electrician. Helped us replace burnt outlet from our dishwasher and kind enough to also help replace power cord for the dishwasher as well at no extra cost. Definitely will use Fuse again next time!
