Every HVAC company I called either didn't answer or was booked out for weeks. AOL Heating & Air was completely different. Avi, the manager, genuinely cared about our situation and made sure a technician was sent out the very same day. Christian and his associate arrived promptly, were incredibly professional, and quickly diagnosed the issue. After multiple other HVAC companies told us we needed a brand-new compressor that would cost us thousands of dollars, Christian found the actual problem and repaired our condenser in just 30-40 minutes. Not only did they save us thousands of dollars, but they restored our air conditioning and had cold air flowing through our vents again the same day. Their honesty, expertise, and compassion are hard to find these days. If you're looking for an HVAC company that truly cares about its customers, provides honest assessments, and doesn't try to sell you repairs you don't need, AOL Heating & Air is the company to call. Thank you, Avi, Christian, and the entire team, you turned an incredibly stressful situation into a huge relief!

    Mike's Air was fantastic. I can't recommend them highly enough, especially Slava, the technician…read morewho took care of us. Our A/C stopped working during a stretch of 100-degree weather. The first company I called I asked if he did repairs or only replacement systems. He said, "I do repairs. That's why it's in the name!" "Great!" I thought. When he checked our system he told me the compressor was bad, which was expected. I asked if he could replace it with a new or reconditioned compressor, but he said no, because the system was about 10 years old and used an older refrigerant. He said the only option wasto replace the entire system. He also said we had an asbestos-wrapped pipe that would need to be removed by another company before he could do the work. He offered to get me in contact with that company, but never did, even after I followed up. So, in the meantime I decided to call Mike's Air. It was late on a Friday. We had Slava out by Monday. He checked the system, confirmed the compressor was bad, and gave me a very different answer: yes, the compressor could be replaced. He was straightforward about the pros and cons of buying an entirely new system vs just replacing the compressor. No selling. Just facts. The price for replacement was very reasonable compared to a full system, so I figured it only has to last about 4 years for it to pay off vs buying a new system now. I gave the deposit and about a week later the compressor arrived. Slava came out the very next day -- on a Saturday -- and installed it. Everything is working again and we couldn't be happier. Not just cuz we saved money (short-term), but I felt confident that Slava was doing a professional job. What impressed me most was that Slava/Mike's Air actually gave us a repair option instead of automatically pushing a full replacement. Slava was knowledgeable, straightforward and professional throughout the entire process, as was Rhea back at Mike's. Highly recommended.

Tech came out and was very nice and respectful of my property. He had to go into the attic and found that the cover was dislodged. He put the cover back on and A/C worked! Was an easy fix but he didn't try to con me and told me the truth. After, he checked the cooling temperature and measured the level of coolant. Gave me straight answers with no bs. Walked him out and asked how much I owed. He told me it's on the house since it was a simple fix. AMAZING customer service and quality interaction. Absolutely top notch. THANK YOU for being honest and providing great service.

    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.

    I recently had a full HVAC replacement done and worked with Mark for the installation. The whole…read moreexperience was excellent from start to finish. 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.

Mark did an excellent job of getting my old HVAC system back up and running, and upgrading some of the components so that we will need fewer repairs in the future. He was clear and concise about what needed to be done to repair the unit. The bill made sense and was reasonable for the work. I was very impressed with his level of service. He also offers a maintenance plan. It far surpassed my expectations. I highly recommend Cityflow.

Their technicians fled our house before we could talk with them about it. Story - Our AC unit started not working and they were quick to arrive and investigate the situation. However, the first technician they sent out thought it was a problem with just cleaning the dust on our blower. Turned out it still didn't work properly after running it later that night - in fact our house got hotter. The same technician came back out the next day after we called NexGen and we found out he had forgotten to plug a wire back in for the condenser on our AC unit - this is a lack of professionalism and care in the work performed. Our AC unit then would only work for about 2-3 hours. We called NexGen to come back out and look at the issue again with a different technician who told us instead we needed a brand new furnace. The next day our furnace was installed, but during the installation, the technicians damaged our ceiling and tore paint off from the ceiling. They tried to glue parts of our ceiling back and it was done so poorly. They even left glue on our walls still. When my wife and I saw the damage done to our ceiling they had already left. I have been trying to get a hold of NexGen since they left and nobody has returned my call for the last 4 days since our installation. The lack of quality of service and attention to detail is embarrassing. The technicians they sent out were also talking loudly about how new they were to the Company - makes sense as to how much of a shoddy job they did.
