Very professional and friendly. Diamond Air services takes their job seriously. From putting down floor protectors to wearing shoe covers. They were priced competitively, kind, and do quality work. They installed a mini-split, hiding all lines, and gave us a fair price. They communicated with us throughout the process and even reviewed how to use the AC after they were finished. To top it off, they put a "Cookie Monster" sticker on the unit since my wife's nickname is the CookieMonster. A great representation of their customer service and attention to detail. Would highly recommend them to anyone. read more

They called me within 5 minutes and had outstanding customer service and answered all my questions and concerns. They sent out a technician same day and fixed the problem and got my heater back working within 1 hour. Thank you for the quick turn around and helping me and my family in time of need. Truly appreciate the professionalism and service. Recommend to all my friends and family! read more

Carl and Dylan provided a great personalized service. They worked consistently until the job was complete, shared what they were doing (which made me a more comfortable and well-informed customer), and left our home as clean as it was when they arrived. I would refer those two to others. I hope management understands their value to the company. The comparative cost of other companies and the service received made this a great 'find' (via Google). read more

I am beyond happy with the work and pricing from Diamond Air for installing a brand new AC unit in my condo. Anthony was professional and friendly, quoting me a great price and recommending that I get other quotes as well. He had given me by far the best price by a couple thousand, and this included a new heater and a top of the line brand (the other companies prices included lower end brands, and no heater). I was sold. Not only was the price point a selling factor, the professionalism and pride they took in doing great work was as well. I lived in a condo bottom unit with no attic, so they had to do a lot of work to put the line in, but when they were done you couldn't even tell where they had cut in. They even put a little fence around the unit so my dog wouldn't urinate on it and ruin the coils. They definitely went above and beyond, even with the little details. I have the only unit in the complex with AC! They did great work and I'm very happy with it and the company overall. Highly recommend. Tip: They do not jack up their prices in the summer like most companies do, but they do get crazy busy during that time, so I highly recommend getting the work done in the off season like fall or winter. read more

Diamond Air Services did a fantastic job installing our furnace. And Joe came out promptly to follow up on insuring the safety of our unit today. He patiently explained and answered my questions. Hurray for everybody's work! read more

My AC went out over the weekend and Howie was able to meet me up super early Monday morning to get it fixed before we start the work week. What a life saver! It'll be over 100 degrees this week and I don't think my employees would've liked working in a hot office. Instead we have cool running AC by 7:00 am Monday! We also have cats in the showroom so Howie helped save them from the heat as well! (They hung out in the office with a portable AC unit while the main AC was out don't call PETA). I highly recommend them for any of your HVAC needs! read more

It was 100 degrees in LA and our ac was blowing hot air. We called around first to find out that other companies charge a ridiculous Amount to fix the ac system. We found these guys through a referral. We are happy we did because the ac is the best its ever been! This company is amazing, they fixed our ac in less than an hour. They were incredibly professional, clean, and quick. The staff is very friendly and supportive. Most importantly our ac is working! I would highly recommend them! :) read more

The plainest ghosted me. Said the give me a quote and never heard back from them. Don't recommend

Anthony from Diamond Air was amazing! He was super helpful, very personable, and gave me the best quote of the three companies that I looked into to replace my entire AC unit. He was very honest about the size of the AC unit I would realistically need rather than try to sell me a more expensive unit. He was able to to give me a quote within a few days and mentioned at that time that inventory was low for AC units, so it may take a while to receive the order if I chose to go with Diamond Air. It took about three weeks to get the unit after I decided to use the company, but when it did, it was a great experience! They were great about texting me and letting me know which technician would be working on replacing the unit and what time he would be arriving. About a week and a half after installation, I called Anthony again because my insurance needed to speak to Diamond Air in order to approve the claim. Within a few hours, he had called and everything was settled. I could not recommend this company any more! I've already recommended it to all my friends and family! Thank you! read more

I called diamond air services to diagnose the problem with my heater. They responded to my call right away.

They did a really good job. Very professional. Will definitely use them again in the future. read more

Amazing...Looked at 4 different company's and Anthony and team hit it out of the park. Delivered the best service and quality around.

Diamond Air Services is now my go-to company for all AC/heating services in Southern CA! These guys are really good. The AC at my parents' home died since last Summer. After getting 4 quotes, I decided to call Diamond Air which I found on Yelp! They came, diagnosed the problems, and recommended the most cost effective way to replace the AC. It's an old home and so all the ducts have to be replaced as well. They did a fantastic job! We couldn't have been happier! I would definitely recommend these guys to anyone who needs help with their AC/heating/duct work. Talk to Anthony or Howie. read more

Anthony and his team are doing a great job. They took 5 hours to clean my tenant's air duct. Their service is good from the beginning till end. Even though my tenant's air duct is not too dirty they still answered my questions honestly. I will definitely have them do my air service in the future. read more

Awesome! Awesome! Anthony hooked it up! Mike was awesome! And Robert was awesome. Straight shooters! Highly recommend.

We live out here in Mission Viejo and it was about that time me and my wife decided to get our ducts cleaned. Will and Paul came to our home and did just a wonderful job! I even had them clean my furnace after Will showed me how bad my blower was. They made sure everything was covered and made no mess which was very important to me and my wife. Great job Guys. read more

Anthony and his team are absolutely amazing. My dog had gone beserk and chewed up the wires behind the a/c unit during a loud thunderstorm. The fuse was blown and I was dreading the cost to fix everything. Bobby and Mike came out to assess the damage. They were very punctual and worked efficiently. They were able to replace the wires and the fuse on the spot and even replaced my air filter for me. Everything was done at an extremely reasonable price. So now whenever people ask me about a/c repairs or HVAC cleaning, I always reply with, "oh yeah..i got a guy for that." These are my guys. I would totally recommend them in a heartbeat. read more

Got an appointment super quick!, Will and his crew were very helpful and super chill. Will definitely use Diamond Air Services again in the future! Thanks guys. read more

These people are really great - we were looking for preventative maintenance, and they were able to provide this for us, no problem. We've lived at our house for going on six years, and it was definitely time to have our HVAC system checked out, and have our dryer line cleaned. Anthony was quick to respond to my request, and was able to pencil us on the schedule pretty quickly. Steve and Trey were pleasant, great techs that got right to work when they arrived. Communication was given at every step of the way, from logistics and travel to what my fan motor assembly looked like as it came out of the attic. I definitely would have them back; their work was exactly as described. The dryer line was our largest concern, and rightly so - Steve showed me the lint pile that had come out of the line. It was definitely a fire hazard waiting to happen. We're right as rain now, and appreciated the service provided. read more

We would highly recommend DiamondAir! Our newly purchased 26 year home was in need of clean and disfected vents to remove the musty smell and results of a remodel. They cleaned all the HVAC vents in our home. We had another unnamed vendor come and quote more than double the price! DiamondAir was prompt, professional and courteous. Steve and Mark arrived on time, put on booties over their shoes, covered carefully with plastic tarps all the surrounding areas around each vent in order to protect our home. We appreciate their attention to detail. Steve did say the vents were not terribly dirty, but, they did have dust and sawdust from a previous remodel. Steve even helped with one vent that need some chalking to align it in place. We would definitely use them again. We now have a clean, great smelling house due to cleaned vents!! Thank you Diamond Air!! read more

Diamond Air Services can add me to their growing list of satisfied customers!!! The employees were awesome. They were professional, friendly and very respectful of my home, even offering to wear booties to protect the floors. They were very tidy and made sure to clean up after they were done. They put in a new air duct system, cleaned the downstairs air ducts and replaced the register and all the grills. I am very satisfied with the service I received and I will be calling them again for routine maintenance. read more

It's hard to find a company that doesn't try to take advantage of you on price and also deliver quality service, but Anthony and his team did both, his price was amazing and the quality of work was even better. I am recommending Diamond Air Services to everyone because they are the best A/C company around. read more

I used Diamond Air to install a new HVAC system. The HVAC crew were professional and knowledgeable and their duct cleaning crew were GREAT....they left my house cleaner than I had it. Howie was pleasant to talk with and was able to answer all my questions; and there price was reasonable. I highly recommend Diamond Air Services and will be using them for my future HVAC needs. read more

We will definitely call them again if we need any services and will 100% recommend ! thanks guys ! read more

If there is 6 stars rating, I will definitely give it to this Diamond Air Service company, especially giving my six stars to the technician Bobby, and the person in charge in the office Anthony. Last December, I called this company for Air Duct cleaning, the crews were prompt and efficient. Later this year, I have an old Hvac/Ac that the heater doesn't work, the AC is not cool enough. So Bobby came over to diagnosis, and he suggested to repair first instead of replacing it even though it is an old system. Their policy is if the repair doesn't work out in the future, they will use the money that I had spent on repairing toward the future's replacing cost which is very reasonable and thoughtful policy. I will definitely refer this company to friends and relatives. read more

The crew over at Diamond Air are second to none. I hired them to service my mom's HVAC system in Irvine and their work was immaculate. They were prompt, thorough and extremely professional. They laid tarp under the areas being serviced and vacuumed up after they were finished. I had a duct cleaning before and they left a mess after they were finished. From here on out it's nothing but Diamond Air for us. Highly recommended!!! read more

I appreciate the work of Paul, of Diamond Air. I wanted him to determine how to optimize clean, smooth air flow in my home. Paul evaluated, reattached some ducting, and replaced some air registers to ensure better air flow. Paul made sure he left all working areas clean. He was very pleasant and efficient. read more
