We're sitting inside cool and comfortable on a hot June day, thanks to the incredible team at…read moreDiamond who replaced our old broken 5-ton AC with a smaller, more energy efficient modern Mitsubishi heat pump system. A huge thanks to Anthony and Tiffany for coordinating all the logistics, Anthony in particular was so helpful from start to finish, always available, responded immediately to any question, and just made the whole process incredibly easy. An especially big thanks to our installer Bobby and his crew who did such an exceptional job carefully removing the old system and doing a beautiful install of the new one. They also completely reworked the AC closet, moving the system forward and sealing everything off cleanly, what was once a poorly converted linen closet now has potential for usable space behind it. Whereas the old system sounded like a jet engine taking off, the new Mitsubishi is astonishingly quiet, the condenser is outside our bedroom and you hear literally nothing. It works flawlessly and has been keeping the house perfectly cool through what's shaping up to be a hot summer. This was not an easy install either. The house, like many older homes, is full of quirks and Diamond did an amazing job working around all the pitfalls that come with squeezing a central HVAC system into a house not originally designed for one. Everyone at Diamond was a total pleasure to work with and have in our home. Their pricing was fair and reasonable and the quality of their workmanship is just excellent. If you need any kind of HVAC work done I highly recommend reaching out to Anthony and the Diamond team. Thanks so much guys!

He squeezed me in the same day, diagnosed the problem, and fixed it really quickly. He was also hones and charged a really reasonable fee. Fast forward to last night (March 2026) when I heard a loud humming sound coming from our HVAC at 7 pm (during another historic heat wave). I located Ash's number and called him. But my phone reception wasn't working. Ash texted me within 3 min to let me know he'd call me later that night, and returned my call by 7:30 pm. He helped me troubleshoot the likely problem and told me to text him photos if I needed further help -- all without collecting any fee. My husband and I are so impressed with how EZ Breeze and Ash run their business. We are calling them for all our HVAC needs.

However, I wasn't satisfied with the estimate I received for the repair. I decided to call around for a second opinion and had the pleasure of speaking with Andrew from Air Flow Bros. After explaining my situation, he took the time to clearly break down why a Freon refill might be necessary and what I should be looking out for with my A/C system. He also shared some helpful tips to keep in mind moving forward. What really stood out was his honesty. He actually encouraged me to go with the best price and mentioned that if I needed anything further, he'd be happy to come out and take a closer look. Overall, I really appreciate Andrew taking the time to provide thoughtful guidance over the phone. I would definitely reach out to him again if I have any future concerns, and I highly recommend giving him a call if you need A/C service. Thank you Andrew!

However we still disappointed with the AC condenser unit that was replaced with the lower efficiency machine that was cheaper and low quality. Well, promise made is not promise kept. It will made my experience whole if the unit was replaced with what it promised. Updates: After I post this review the owner : Sean, was calling me and my wife multiple times, almost every hour. Asking me to take down this bad review. First he asked me politely then he starts threatening me and my wife by explaining what do we do for living and he will start calling my friends, family and workplace where we work. Not sure what he wants to do by stalking our information and being intrusive to our life. He insists to come back to my house which I refuse to give him permission. He threatens my wife by telling her that he used to be a bad guy, and I don't understand why he starts getting violent and seek revenge against my family. So I decided to file restraining order with Los Angeles County Court to protect my family against his violent nature and behavior, per our lawyers advise.
