The first time, I called at least a dozen different companies here on Yelp and none of them were willing to come service mini-splits, so not only was Milad actually willing to come out, but he came out within the day, diagnosed the issue, tightened the loose fittings, and refilled the freon in the unit, all at a pretty reasonable cost. The most recent time, he came out, checked the error codes, reset the systems that were erroring, and charged just a diagnostic fee for the work. Additionally, I really appreciate how easy he's been to get in touch with since I haven't been able to make it in person either time. Between texting, calls, and pictures and videos that he sends, he really offers peace of mind for the work he does! I'll definitely be continuing to reach out to him for future HVAC needs, thanks Milad!

Shay was extremely thorough in his inspection and called out the best possible system improvements we could do for our old home, including brand new attic insulation and duct work. He was extremely patient and helpful while we worked on the financing of such a big but important home improvement process and was there to answer questions/concerns every step of the way. When we finally were able to hit the green light on the project, no time was wasted. Shay scheduled all the work (including a crane!) for the following week and the incredible team completed it all in 3 days time. Huge shout out to the entire team including Adonis that absolutely killed it with cleaning up the attic and installing new insulation, and Kamo and team with the intricate HVAC electrical work and overall installation. The entire crew killed it and can't beat a 12 year warranty on such a big purchase.

In this regard, Jesus came out to look at our AC system yesterday, which has been working only intermittently. Following a very thorough diagnostic assessment of the overall unit, Jesus suggested that we hold off installing any new parts at this time, as the system is somewhat old and doesn't provide any specifics concerning what needs to be replaced. Indeed, I appreciated Jesus's honest and straightforward assessment, as opposed to relying on guesswork to resolve the problem. At this point, I expect that we will likely be replacing our aging unit sometime this year....and, without a doubt, Manny's will be the company I call to do the job. Along with providing prompt and excellent service, the three technicians I've met from his company have all been very professional, courteous, and personable.

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!!
