    I needed to replace my 20 year old AC unit. DWP was offering some attractive rebates to go with a…read moreheat pump, so I called GIV for an estimate. They were available instantly, but I had planned a little bit of lead time Oleg came over at the appointed time and took a look around. It's a little thing, but I appreciated the fact that he noticed we don't wear shoes in the house and offered to take his off without me saying anything. My kid was off from school and he was very kind to him. He gave a very thorough examination and explained his findings to me. He has an excellent eye for detail. He is very committed to his values and what his experience tells him and I respect his opinion deeply. We ended up selecting another proposal. In spite of that, Oleg was kind enough to give some advice in terms of the other proposals I was selecting between. I have no reservations whatsoever about recommending his services. He was very easy to work with and to talk to. And while I hope he doesn't have the opportunity to tell me "I told you so!", I would absolutely give him that chance.

    If you're looking for an AC installation company, stop looking and call GIV HVAC right away…read more We only had wall units and an old, broken swamp cooler before and they installed a complete central heating and cooling system from scratch. I just had them do the whole job and they were excellent. Oleg, Igor, and the team showed up on time, worked super fast, and got everything done quickly and efficiently. They were really clean, left the place spotless, and their pricing was very fair and one of the best quotes I received. The new system is running perfectly and they made the whole process so much easier than I expected. I'd definitely recommend them to anyone who needs AC work done. Thanks again to Oleg, Igor, and the whole team!

    I highly recommend this company for its integrity, transparency, and exceptional customer service…read more We recently purchased a new home and received an inspection report stating that our HVAC system needed several repairs. Wanting to make sure everything was addressed properly, we contacted several HVAC companies for evaluations. Unfortunately, many of them recommended expensive repairs and upgrades that would have cost us thousands of dollars. Then we called Around the Clock for an additional quote. Michael came out and gave us a completely different experience. He performed a thorough inspection of the system and, instead of trying to sell us services we didn't need, he was honest and straightforward. He explained that our HVAC system was functioning properly and that no repairs were necessary. In today's world, it's not often that you find someone who values honesty over making a sale. Michael saved us thousands of dollars in unnecessary expenses and gave us peace of mind about our new home. His professionalism, knowledge, and integrity were truly refreshing. If you're looking for an HVAC company you can trust, I highly recommend Michael Around the Clock.

    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!!

After getting a few estimates, I decided to move forward with Mark for the job. My old system had a refrigerant leak in the evaporator coil and it wasn't worth repairing anymore. Mark walked me through the the different options clearly and made recommendations. We decided to replace our system entirely with a Trane heat pump setup. He explained everything in a way that was easy to understand without any pressure. What really stood out is that he went above and beyond during the installation. He sealed the cavity below the indoor unit and installed insulated reflective panels around the area to improve efficiency and airflow. He also replaced the threshold in my utility closet with sheet metal to properly finish the space and make everything look clean and professional. Another thing I appreciated was how careful he was inside the house. He wore shoe covers while working indoors and laid out mats from our door to the work area and was very respectful of our home. The installation included the new outdoor heat pump, air handler, coil, electrical disconnect, and proper commissioning. He made sure the airflow was set correctly and scheduled a HERS verification so the system meets California energy standards. The system is running great and the house is comfortable again. It's clear Mark takes pride in doing things the right way and not cutting corners. I'd definitely recommend him to anyone looking for a knowledgeable and trustworthy HVAC pro. He's now my go to.

He was extremely professional, explained everything clearly, and showed us what he was talking about whenever possible. I really appreciate the nononsense service he provides.
