Fusion Star Inc.

I can’t say enough GREAT things about Sean and Fusion Star. An HVAC company that is trustworthy, reliable, knowledgeable and conscientious! The first thing you realize upon meeting Sean is how intelligent he is and how much he understands his field. As a homeowner, I am not an expert in this area, but Sean is.
A word about scheduling: both times we needed Sean’s help, it was for emergency reasons. Naturally he has plenty of jobs scheduled in advance, but Sean worked some magic and was able to fit us in over the course of partial days so that we didn’t have to wait a couple of weeks for him to have time. We are so thankful to him for doing this.
Additionally, one time when a repair didn’t go quite as planned, Sean cut short a vacation just to come back and help us out during a particularly hot Valley week. I mean, who does this? Just wonderful.
We have used Sean for two different AC units/furnaces in our home. Our first experience was when one furnace stopped working. Sean and his amazing crew had to work in our very difficult attic space. While they were there, Sean realized our ducting was too small for our upstairs, so no wonder it never really got cool! He fixed this issue, and many others, and now our upstairs is cool, even with very high ceilings.
Our second AC unit was old, but functioning, when our furnace stopped working. He replaced everything at the same time (instead of piece mealing it as items failed) and things are working better than ever before. Quieter, faster, and more efficiently. Sean is great at explaining the workings of these pieces of equipment so that you select items that work as opposed to overworking.
I literally can’t say enough great things about Sean and his wonderful crew of talented guys. He better never retire!!!!!

After receiving 5 estimates from high rated hvac companies, Fusion Star was the best choice for us. Sean is very detailed and knowageable and gave us options to best fit our needs. We replaced 2 heaters and 2 AC units along with all the ducting and Sean designed a 4 zone system that we are extremely happy with. During the process Sean and his crew were on time, clean, respectful and trustworthy. The inspections we had all passed with flying colors along with the inspectors complimenting on the quality of the work that was done. We highly recommend Fusion Star for your HVAC needs.

Our A/C broke just as it started to get hot, nightmare! We contacted a number of HVAC companies for bids - Sean visited and spent over an hour with us investigating the current system, showing us how we could keep it limping along until we were able to book in an install, and working out what a replacement should actually look like. We didn't directly discuss the other bids, but in his visit Sean showed us a number of problems with our AC intake and ducts which the other companies had glossed over. Quick research showed he was absolutely right, and we'd have spent a lot of money with other companies replacing our HVAC to still have it run inefficiently.

We were worried about having the work done because of the infection risk from Covid, but it was almost summer in LA with a young baby, so there was no option but to fix things and stay cool. Sean and his team were incredibly careful, wore masks at all times and kept as much distance as possible. They were extremely friendly and professional, I always knew when they were showing up, what they were working on and what was left to do. They even tried to keep noise down to a minimum to help our baby nap.

I wouldn't hesitate to recommend Fusion Star. They are not the cheapest option, but if you need major work done it's always best to hire professionals who are willing to spend the time to get things right rather than a company looking to get paid and get out.

After contacting several different companies on a new HVAC (my old one died), I was immediately impressed with Sean's attention to detail and willingness to educate me, the customer. The other guys focused all on price and their expertise "I'll do a good job" or in other words "Trust me".

However, Sean told me exactly what was going to be done, how it was going to be done, potential issues and workarounds. I felt so confident he and his team would be the best people for the job that I cancelled with another company and delayed my install. The best thing was that everything Sean told me on the phone, was in writing. These other guys had short form contracts or sales slips - all about the money in other words.

I had an issue after the install related to a sound coming out of the bathroom sink in my tiny condo. Sean and his team took the time to help me with a solution (more related to my plumbing setup than the install) and did not charge me extra even though they had to come back and creatively trouble shoot and spend additional time and effort resolving the problem.

I could not be more happy with the process and end result- new HVAC, more efficient Vents (they look better too) and an Ecobee4. I now have an energy efficient HVAC with a top job. He and his team are not just good, but they are great! My expectations with the end result were not just met, but exceeded. I would strongly recommend anyone needing HVAC services to use Sean/Fusion Star. After previously contacting several other companies in the area for estimates etc. I am certain, no one else would do the top quality work him and his team have, or have the patience to educate the customer the way he did with me.

We needed to replace the ductwork in our two-story house. I talked to several other companies before choosing Fusion Star to do the work. Sean inspected our HVAC system thoroughly and provided several very detailed options. He answered all my questions and I was impressed with how much care he took to address each issue. We chose the option which involved reconfiguring the system with larger ducts and moving the furnace so that the heat and air would be distributed more efficiently throughout the house. Fusion Star also installed a new energy-efficient air conditioner, two zones, and Ecobee thermostats. The workers were always professional and polite, wore masks, and they protected the floors and left the house immaculate at the end of each day. They expertly patched the walls where needed and installed new registers and an access door that all look great. The difference between the old system and new system is like night and day and there are no longer rooms in the house that don't get enough heat or air conditioning. Each room is at a comfortable temperature, and that's been very important with everyone working from home. I highly recommend Fusion Star.

Sean responded asap to my issue with a dryer vent, showed up the same morning with one of his crew members, diagnosed and gave a reasonable estimate for the fix. The work was completed two days later, no mess, no problems and I now have a functional vent system through the attic from the laundry room. I am very grateful for his expertise and professionalism not to mention punctuality and most especially for averting what could have been a fire hazard.

AC Repair – there is a huge gradient of HVAC installers out there and you really need to do a lot of research and ask questions before settling on an installer. In my case, I had a 35-year-old house and the Furnace was about 15 years old: AC was older. The Compressor died and it was not cost effective to just replace the condenser. The ducting needed serious attention (2600 sq. foot, 2 story house). I had quotes as low as $7k for just changing the AC/Compressor (using the existing furnace) to $26k for a complete HVAC replacement.
After talking to a number of installers, I quickly learned that some did a thorough job explaining what work needed to be done. Some suggested solutions that were code violations. Others provided only partial quotes AC replacement (didn’t even go into the attic to look at the system). Some quoted a 6 hour install and some quoted that it would take a week or so.
I selected Fusion Star because after talking with Sean, I had a high confidence in their ability to professionally execute the installation. I asked a lot of questions and talked about various alternatives. Sean answered each question with a depth of knowledge that was very impressive. Additionally, he was able to clearly articulate the pro’s and con’s of each alternative. Fusion Star was also knowledgeable and helpful about Energy Rebate programs and helped to select a system that earned us a $1.3k rebate from SCE. We also upgraded our ducting system to increase the overall effectiveness of the HVAC system. We also zoned the upper and lower sections of the house. To be clear, Fusion Star is not the least expensive installer out there. That being said, confidence in a contractor will give you peace of mind and reduce your overall stress.
The job was completed on time and on budget. As with any installation, the are a few bugs to work out and Sean has been on top of any issue in a timely manner. As a side note, if you get a permit the installation will need to be inspected. Both the HERS tester as well as the Calabasas Building inspector were impressed with the professional installation of the HVAC and went into detail discussing this with me. I highly recommend Fusion Star for your HVAC needs.

Sean was amazing. Called him to get a quote to replace my old compressor. He came over and listened to everything I had to say and then looked at my system and suggested what I needed. He did not try to give me a sales pitch nor did he come with a 15 page presentation (which some of the HVAC companies I dealtwithd did) he even told me what I don't have to change and by doing so he saved me money.
I will highly recommend him for any of your HVAC needs.

Sean is very thorough, good quality units and will discuss options with pros/cons so you get the right unit for your space, price range, etc. It is obvious he knows his business. Continues to do maintenance annually and available if there are any issues. Pleasant to work with

Had an issue with my ducting. One of my rooms was not cooling off properly so had them come out and see what was going on. Turns out my ducking was extremely old and was actually shut off to the room. Since he was able to show me the condition of the ducts and all the disgusting hair and particles that where living in my ducts I decided to replace them. They where able to come out the same week and get it done quickly since it was so hot outside. I felt very thankful to the guys working in my addict when I know it was 100+ degrees up there. Overall really please with my experience.
