    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.

    It is hot in the valley and my A/C refused to turn on. I was going crazy trying to figure it out…read more Contacted Mike's Air via yelp and they were able to come same day. 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.

    I received three quotes from people arranging anywhere between 28,000$- $35,000 to replace my A/C,…read moreunfortunately my house was too big for only one unit so I was ready to pay a whole lot of money Avi came and suggested a few mini split units in the rooms which we are not using and then direct the old A/C to the rest of the house while providing a major clean out and maintenance for the existing one I really thought my old A/C is dead and needs replacement but apparently Avi brought it back to Life and it's absolutely kicking right now I've ended up paying less than a third of what everyone else offered me and he also cleaned out years of pollution in the system my A/C is working better than ever

    I cannot recommend AOL Heating & Air enough! I'm currently 8 months pregnant, and our A/C stopped…read moreworking during a brutal 90+ degree heat wave. 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!

    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.
