5 Stars - Sean at Fusion Star Sets the Gold Standard for Professionalism…read more I recently got multiple bids for a full central HVAC replacement and complete duct redesign on my home in the valley. While I held off on my project for now, I have to give Sean at Fusion Star an enthusiastic and well-deserved 5-star review. Sean delivered the most comprehensive, professional, and detailed proposal among all -- a full 15-page document that spelled out every single detail with exact equipment models, clear scope of work, diagrams, attic prep requirements, and thoughtful exclusions. In a field where many contractors cut corners, give vague estimates, or try to low-ball with minimal information, Fusion Star's proposal stood head and shoulders above everyone else in quality, transparency, and legitimacy. Even after I let Sean know I was pausing my project, he continued offering thoughtful advice on what to double-check and which key items I should make sure were included if I went with anyone else in the future -- all with zero benefit to him. That level of genuine care and integrity is rare and extremely commendable. If you're looking for a legitimate, high-quality HVAC contractor who truly puts the customer and craftsmanship first, I highly recommend Sean at Fusion Star. They earned my business in every way and I won't hesitate to call them first when resuming my project or any related future work. Thank you, Sean -- you run a class-act operation.

In the past, I had always used Conejo Heating and Plumbing, but unfortunately I had a really dishonest experience with their plumber last week and no longer felt comfortable supporting that company. So I turned to Yelp and found this company. I reached out and received a very quick response from Sean. He was able to come out just a few hours later, successfully diagnose the problem, and replace a part for a very reasonable price. He was honest and transparent, and I really appreciated that he tried a few different solutions before getting the unit up and running. I'm happy to say I've found a new go-to AC company. It's a smaller business, which I always like to support whenever possible. Highly recommend!

I came across an offer from an affiliate of Home Depot for an AC tune-up for $8.88. Thought it was…read morea great bargain, and I'm sure many of you would too. So I'm going to give you a forewarning, it's a classic bait-and-switch (i.e get your foot in the door and then upsell). I was recommended a hard-start kit (aka compressor saver) and an air purification system. The cost? $1,800+. I told the tech that that's a bit steep for me, so he said, how much could you afford? I said maybe closer to $1,500. The tech called his manager and inform me that they would do it for that price. Initially, I was happy to receive a 20% discount. That is of course, until I googled the PlasmaPure 600 Series and the hard-start kit they sold me after the technician left, and discovered I paid $1,200+ for 2 hours of labor. This was back in June 2025. Give or take 10 months later, my air conditioner stopped working. Normally, I don't turn the AC on during the winter season, but as luck would have it, Los Angeles is having record breaking heat. I haven't used the AC for several months, and I only had a tuneup a few months before that. So I called the same company to determine why my AC wasn't working (hoping that they would stand behind their work). Upon opening the equipment, the hard-start kit they installed in June had exploded. The cause, according to their tech, was that my AC compressor was grounded. The good news? Because my Lennox unit was less than 10 years old, it's still under warranty. The cost to install and repair it? Over $5,000...yikes! :-z But the $88 you paid us today to inspect the unit will go towards the cost of the installation. That's how they get you by the way, by offering you a lower inspection charge. Since this company pulled a fast one on me last time, I decided to get a second opinion. I called Around the Clock considering it was them who initially installed my Lennox unit. They sent Oleg Stopsky out the very same day (I should mention that the other company took over a week to schedule a tech to come out). He confirmed that the compressor is in fact grounded. But because I'm a repeat customer, the cost of labor would be less than 1/3rd of what this other company quoted me. Additionally, the $125 I paid to have them come out to inspect, would be discounted from my total cost. I wanted to get a 3rd opinion just to make sure. I hate to say it, but when you're a solo female, you can easily get duped. When it comes to mechanical stuff, most technicians just assume you don't know any better...and in my case, it's somewhat true. That's why finding an honest company is so important. I contacted a company that was affiliated with Costco. They said they would give me a complimentary inspection. They too said that the unit was under warranty but their quote to repair was more than double of what Around the Clock offered me. I was glad that Around the Clock was the lowest because they were the most expedient and pleasant to work with. So as soon as Lennox sent Around the Clock the compressor, the contactor, and the capacitor, they scheduled Oleg to come out the very next day. I felt really bad because my AC is located on the roof of my building and we had record breaking heat today. But despite the unbearable heat, he remained jovial throughout. He did a superb job and was kind enough to install a permanent dryer filter when he learned that I had weak lungs. And just to show how honest they are, I asked Oleg if I should install a hard-start kit as recommended by the last technician, (because the previous one they installed in June exploded), he told me no. That since we replaced both the capacitor and the contactor (which were also under warranty), it's no longer necessary. This is probably why he's been with this company for over 25 years...because he's honest. I also like that I'm supporting a Ukrainian business. No more paying technicians from multiple companies to come out and inspect in the future. My HVAC company of choice is now Around the Clock. I'm so relieved to have air conditioning again...hallelujah!!

If you are a Costco member there are occasionally incentives offered as high as 15% of the purchase price in addition to other incentives available for a limited time that help offset the price of a new system.
