Fusion Star Inc.

Sean and his crew are extremely professional, clean and very knowledgeable. We live in a 96 year old house. Our 20 plus year old furnace was working but was not very efficiently. We have put off replacing it until we finally decided to install AC. Sean did an assessment of our home, measured each room, calculated how many registers and what size each room required to effectively heat and cool the space. We met on several occasions to discuss our budget, how many zones we wanted, what brands he suggested for our needs, where would we install the registers in each room and the outdoor equipment, etc. We settled on a Mitsubishi 3 zone system. One zone for my mother in law's suite, one for the rest of the first floor and one for the entire second floor.

The install was performed flawlessly and in an extremely timely manner. Sean's attention to details is very impressive. He really strives for perfection in every aspect of the job. He does not believe in short cuts. Sean is as much concerned with the aesthetics of the install as he is with the mechanical aspects. He figured a way to run all the lines to the unit in the attic through one of the unused old ducts so we have no mechanical lines running up the outside of the house to the attic. The install ran into a small communication problem with one of the units, it was working but not to Sean's satisfaction. He made countless phone calls to the Mitsubishi reps until he was given a solution he was satisfied with.

The inspection was unusual in that the first inspector was not familiar with our system (relatively new product line) and really didn't understand how it worked. So, he return a few days later with his supervisor to complete the inspection. The supervisor was so impressed with the installation he pulled me aside and told me he usually does not comment on the installation it self to the homeowner but in this case he had to express this was one of the cleanest installs he had personally seen.

We did get a few other quotes from other HVAC companies, Fusion Star was not the less expensive but I feel you get what you pay for and I believe we got every penny of our money's worth!

Sean is meticulous, professional, timely, and basically everything you could ask for from a hvac company. He and his squad replaced a very bad installation on time and in budget, and ever since, has been immediately responsive and available as needed. I can't recommend him and Fusion higher.

Sean and the Fusion Star team are the real deal. Prompt, efficient. Living in the valley with temps regularly hitting 100+ they’ve done a great job keeping our home cool. Can’t recommend enough.

This review is long overdue. Simply put Sean did an outstanding job on the installation of a Mitsubishi ducted mini-split system. His quality of work and attention to detail are second to none. I've never seen a contractor prepare such a detail written scope of work and estimate. For my job, I literally had a detailed 10 page written estimate and scope of work. The scope of work covers exactly what Sean will do - there is no guess as to what is covered or not covered.

As far as workmanship and attention to detail, Sean completely surpassed my expectations. My particular job was difficult in that the existing roof mounted AC unit and ducting was replaced with a ducted Mitsubishi mini-split system. Complicating the matter is my crawl space is very tight and part of the house has a flat roof. While challenging, Sean was able to not only duct the entire system through the existing crawlspace, he cleaned out the crawl space, insulated it, and then installed "catwalks" with lighting in order to service the units. Simply amazing. The other thing about Sean is that he schedules the annual maintenance for the units and it's like clockwork, and of course if you have any issues with system Sean is always ready to address it.

In summary, if you need to replace your AC system, you should absolutely give him a call - you will not regret it!!

I contacted Fusion Star as part of a in-law unit remodel, which included updating the furnace and AC unit. The end result is better than I expected, thanks to Sean's ability to suggest the best solution to my problem, vs just being an order taker, as well as high quality execution.

I initially expected we'd need to change the furnace and AC unit in a like-for-like switch (because they were vey old), and redo all the duct work (because of the new configuration of the rooms due to the remodel). Sean politely suggested an alternative for me to consider, which was to go with a heat pump and splits. He was very upfront with me that the option was a little more expensive to implement (though cheaper to run in the long term), and helped me think through the pros and cons of doing this vs. doing a like for like replacement of the legacy system. I could tell he was really trying to get in my shoes to figure the best option for me.

I opted for the newer technology and couldn't be happier with it. As a bonus, the new system takes a lot less space than the old one so I recouped some living space. Additionally, Sean and crew do very good work. Sean personally inspected every stage and ensured everything was not only to code, but also looked perfect.

Last but not least, you can tell Sean really cares for his customers. For example, while he could have just paid attention to his part of the project, he observed what we were doing with the remodel and offered some suggestions based on his vast experience with home projects. They were always great ideas that made us think "why didn't we come up with that idea on our own???"

Thank you Sean and Fusion Start crew. I have your number saved in my contacts for any future needs!

My home needed a complete rip and replace for two systems. Sean took the time to understand exactly what I was looking for and executed flawlessly. He even talked me out of a couple of systems that he knew would not accomplish my goals. His attention to detail and quality was exactly what he said it would be. Strongly recommend this company if you're looking for an honest assessment of needs, attention to detail and great execution. After a two week almost seamless demo and replacement of my 32 year old systems and ducts, everything worked great. However while doing the quality control walking through the installed systems, Sean found a couple of things that we're perfect. They were quickly corrected and I remain very impressed.

Fusion Star is by far the best HVAC contractor we have ever found and is one of best contractors of any type we have hired to work on our home. At a neighbor’s recommendation, we included Fusion Star among the firms we considered when we decided to replace our HVAC system. Our meeting with Fusion Star’s owner Sean, together with his reasonably priced replacement proposal, quickly established Fusion Star as the best candidate. Sean is very knowledgeable, helpful, and detail oriented; he spots potential problems in advance and offers constructive solutions.
Fusion Star’s work crew arrived on the agreed starting date for the project and finished it in less than the estimated time, despite a heat wave. They thoughtfully provided a portable AC unit to cool part of the house for us while they worked. Sean discussed the work with us as it proceeded and passed savings along to us when he found items at a better price than his original estimate. His crew carried out the project in a very responsible manner: when they found unanticipated problems, they resolved them in a reasonable and professional way.
The quality of the finished installation was very high. After the project was completed, Sean provided us a training session regarding the new system, together with a set of photos and records documenting the project and information about possible rebates. Overall, our view is that Fusion Star is one of those rare gems one occasionally finds among Los Angeles contractors.

I first met Sean when I needed an inspection done on a house I was considering purchasing, and was very impressed with his professionalism (dealing with an incredibly arrogant and rude developer/seller) and received a very detailed report from him extremely quickly. He also followed up as the sale went through and made sure I knew I could call any time with any questions - as the inspection had shown various issues that would need remedying in the future. Sean made a note to follow up in six months, and that's exactly what he did!
Luckily the follow up call came just as we started to have some hot weather - as the mini split unit in the Master bedroom was not working (not fitted correctly by the developer) and was leaking coolant. I decided to bite the bullet and replace the cheap noisy thing altogether, and replace it with a better system, and to have it placed on a different wall.
Sean's quote was very reasonable, and included patching up the area where the old unit was, as well as providing a new much more efficient system. Within a week it was in (the team took just one day to remove, install and patch everything) and working perfectly. All the guys from Fusion Star were very polite, careful and left the room cleaner than it was before they started!
I can't recommend Sean and his team highly enough - he's already followed up again to check everything is ok, because he really cares that his clients are happy. If I ever have any issues or questions, Sean will definitely be my first call.

Sean and his team are fantastic. They installed a complete new HVAC system in our home. Sean spent a lot of time walking us through our options and ensuring that we're comfortable with the work done and the final product.

I can't recommend Fusion Star more. They're honest, dependable and take incredible pride in their work. I'd give them 6 stars if I could.

Sean is an absolute GOAT (greatest of all time). He responded to my inquiry within a few minutes and made it out the next day to inspect my HVAC system. He is extremely knowledgeable and overall a genuinely good person. His initial hypothesis of what was wrong with my equipment was spot on and he was so patient with me in explaining the issue and describing all my options. We replaced both the indoor and outdoor unit with the most appropriate equipment to fit my needs; massive shoutout to Sean for the excellent recommendation! Best of all he made everything work around my availability and even had everything up and running ahead of schedule; a real life saver! Additionally, he has an exceptional team at his side; a group of very experienced and hard working individuals. Sean and his team far exceeded all my expectations. I highly encourage collaborating with Sean for all your HVAC needs!
