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!

This was my first time using their services but when I needed a new central HVAC for my home, I…read morewent through Costco and Around the Clock is their current subcontractor. Michael handled all the business and clearly explained to me in my home what equipment options were available (all Lennox via Costco) and what payment options and benefits were available to Costco members. I took a few different estimates from other companies and although I found comparable equipment and installations that might have priced out cheaper than Around the Clock, the benefits received from Costco for CostcoCash along with direct cash refunds made them very appealing. Michael is very patient in the process of answering any and all questions regarding the equipment, installation, etc. The installation was smooth and painless. The team of two installers were polite and professional. They worked clean which is greatly appreciated. The installation took about a day and a half. End result: I'm very satisfied with my experience with Around the Clock. A very professional installation with great customer service. The new system has completely transformed the comfort level of my home. It's already been battle tested in this SGV summer and I couldn't be happier. If you're on the fence in deciding whether or not Around the Clock is a vendor you'd like to use, I whole heartedly recommend them.

The first tech found "no issues" and left. *Inflated $2,401 Quote: On visit #2, they finally confirmed the failing ECM motor and quoted $2,401.20 out of pocket, claiming it was out of warranty. *Active 10-Year Warranty Ignored: I called the manufacturer (Carrier/Day & Night) directly and verified the unit is under an active 10-year Enhanced Parts Warranty ($0 OEM part cost at the counter). *Refused Warranty Exchange: After I provided the official Carrier registration confirmation number, they admitted they aren't an authorized Carrier dealer and insisted I pay the entire $2,401 upfront and wait on a potential $1,151 reimbursement. Even with their math, they were charging over $1,250 in pure labor for a 2-hour swap.

$700.00 AN HOUR Yep, a friendly serviceman came, did a basic…read moreair conditioning repair and he did a good job. But, I timed the visit, and it was a few minutes under an hour, and that included everything; the estimate and repair labor. The bill was $ 758.00 for that hour. I talked to the repairman about the cost of parts versus labor and he said they were not separated out. I talked to the business owner later on. He said that of the $758, the parts were about $80....although I found Amazon is cheaper. He did go through his costs with me, stating they were part of the job, but most had nothing to do with the repair but rather, costs of running a large corporation ......costs such as .....employee benefits ......travel time to and from the job ......office management ......payments on his fleet of trucks, my guess ......profit for the owner that the worker never receives. On the other hand, the costs of a self-employed serviceman would be parts and labor only, in his bill, usually $50-$100 an hour plus parts. So, bottom line, it was a simple job with cheap parts which I accepted ....trusting that it would require more time and cost than it actually did. My bad, I should have gotten another estimate, which means a second cost for a second estimate, but in this case I should have paid it. SINCE I KNEW THE REPAIR THAT WAS NEEDED, I SHOULD'VE BEEN ABLE TO BARGAIN A BIT LOWER WITH SUBSEQUENT CONTRACTORS... SOMETHING I WILL REMEMBER IN MY FUTURE CONTRACTED JOBS. My view, everything was legal, but the service of a large air conditioning company should be noticeably cheaper or else it offers no benefit to offset the cost. I saw no such benefit. Finally, I would encourage you to talk to the owner, he's pleasant and well spoken. He will have a lot to say.
