    Almost done... check out the hanging rods, fire protection plate, and the beefy cross bars!

    My 23-year-old HVAC system recently died on the last day of 2020. After multiple quotes from many recommended HVAC companies, I ultimately chose Stewart Air Systems to overhaul my entire heating and cooling system. Justin provided me with a detailed quote of multiple options after evaluating my house and paying attention to what I was looking for. The quote I received was very well written, detailed, and clearly showed the price breakdown I was looking for. Ray and Paco were the installation team. Both Ray and Paco are professional, courteous, very hard-working, and paid great attention to detail. They went above and beyond to not only adhere to COVID precautions (face masks, gloves, and kept their distancing) but kept our house clean with drop cloths and cleaned up after each evening before leaving. The job took over a week, but we didn't mind because Ray and Paco didn't rush the job and were proud of their work. Ray was awesome and didn't mind helping me fix some of the disconnected lights in the attic and checked on some dilapidated bathroom vents. Paco even painted the attic door for me without me asking, along with the inside return vent. Both guy's attention to detail was such a relief. Overall, I had a great experience with Stewart Air Systems and felt I received a fantastic deal with the unit's price and the craftsmanship of the overall installation and service. I'll be adding Stewart Air System to my speed dial for future HVAC repair and services from now on!

    Great people! They replaced a condenser coil that had a leak (installed originally by other company) it was under warranty by the manufacturer and Stewart helped us dealing with them. I will hire them again if I need anything else related with HVAC

    I used my trusty Yelp app to find a quality HVAC company that wouldn't try to pull my undies down and take advantage of my posterior. I found them! Thank you, Yelp buddies! You didn't let me down this time. Stewart Air Systems gave a free estimate, responded when they said they would, and completed the work as described. The estimate was reasonable and a lot cheaper than several other companies. It was like getting filet mignon from Flemings at a Black Angus price! I would absolutely recommend Stewart Air Systems in the future. Both brothers did a tag-team effort on my job and I was completely satisfied! Yelp 2017 challenge 16/100!

    I see all sorts of Air Conditioning/Heating company vans on my way to and from work...I even called a couple of them to get quotes on our mini-split system. I also looked at the reviews on Yelp and based on the reviews, decided to call Stewart Air Systems. I am so happy I did! From the first moment they were courteous and respectful. I admittedly needed some guidance and it was provided without any "upsell" attempts. The installation occurred over the 4th of July holiday, so it was slightly delayed, but since the installation, it has been bliss!!! Good work, good company, but most importantly they are really, REALLY good people! I was so happy I could support a local, family run business! I could not recommend them enough. It has been hot and will be getting hotter...I could not be happier with their work. If you are looking for A/C Heating service, call Stewart...you will be glad you did! Oh, and the dogs loved them.

    Lastly, during one hot summer day, to my surprise, Steve texted me asking if the systems are working properly.

But the most important thing I can say is that he is just a good man. He will deliver what he promises at a fair price, and won't stop until the job is done. That's all you can ask for from any business.

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.

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!

I spoke with Barbara and I let her know my situation that I had two mini split units that needed a deep cleaning ASAP because I noticed mold was inside the units. Barbara confirmed with the technician and was able to set up appointment for same day with a small waiting window from 2pm-4pm! Other companies were giving me long waiting windows on when they might show up. I also love that she was able to give me an upfront price on servicing my two units!! Daniel and Eric were the two technicians that came out to service my units. Daniel was very knowledgeable, helpful, and kind. I explained the situation with the units and he was confident that he would fix the situation. Before he started, he let me know what he was going to do to deep clean the units and remove the mold and gave me another option just in case it didn't work. His confidence put me at ease as I was stressing so much about this mold situation. Daniel and Eric were very professional and we were able to get the job done and had my units looking brand new! They made sure there was no mess left behind and the areas that they serviced were clean. They showed up on time and actually a couple minutes early, which was a great surprise. I appreciate that they wore shoe coverings when working inside my house. I didn't even have to tell them or ask them. They already had the coverings and put them on before they even walked in. Overall, it was a fantastic experience and would definitely recommend to anyone needing service! Thank you for all your help and taking care of this stressful situation!
