From routine maintenance to service calls, they've always been professional, honest, reliable, and incredibly knowledgeable. The technicians are punctual, friendly, and take the time to explain everything clearly. I never feel pressured into unnecessary repairs--they genuinely care about doing what's best for their customers. It's rare to find a company that consistently delivers outstanding service year after year, but Diamond Air Services does exactly that. I trust them completely with my HVAC needs and recommend them to anyone looking for dependable, high-quality service. Thank you for five years of exceptional work. You've earned a customer for life!

Contacted Diamond Air on 8/25 to inquire about options for ac service at a house. Tiffany was very…read morehelpful and friendly, as she always is when I call. She stated that Anthony would come out the very next morning and see all options available. The very next morning, Anthony had completed a thorough and detailed estimate with pictures attached. The pricing was a lot lower than I even imagined, especially after dealing with another AC service provider (which I will never do business with again after the great service and pricing from Anthony and the crew). Was scheduled to have work start by 9/1 but received a call from Anthony advising that his crew would be out a day sooner to help with the heatwave. A new AC unit and furnace were installed along with everything that goes with it. They even did some drywall work! Anthony and the crew at Diamond Air are our go to ac and furnace providers. They stand behind their work and their great customer service makes it easy to do business. Shout out to Howie as well. He came out in February to check something another ac company scared us about. He explained there were no issues and helped put us at ease. The other company wanted us to pay for services we did not need but Howie was about honesty, not profit.

Air Ducks cleaned my air ducts and dryer vent this week and did an absolutely great job. The Air…read moreDucks technician Chris did a thorough, detailed job and really went above and beyond. Chris also found an issue with the roof cover of our dryer vent and took the initiative to fix that. I've had a lot of workers in my home and by far, this is the best experience I've had. Also, we were able to schedule the visit within a couple days of reaching out to Air Ducks, pricing was competitive and we were not up-charged (I had 3 other Air Duct cleaning companies that either quoted me outrageous prices or kept pushing add-ons. Air Ducks gave me a price over the phone and that was the price I paid. I'm so pleased with this company that I've already given their name to several friends and my next door neighbor has already booked a cleaning with Air Ducks. This is a great company, Chris is an outstanding tech, and I will use this company whenever I need duct cleaning for many years to come.

Sky was an outstanding technician sent by All City. He arrived quickly, diagnosed the issue…read moreefficiently, and was honest throughout the entire process. I really appreciated that he gave me several options to consider instead of pressuring me into one solution. What impressed me most was how clearly he explained everything. Since I know very little about how HVAC systems work, he broke it down in a way that was easy to understand--almost like he was teaching an elementary school student, but in the best way possible. He was patient, knowledgeable, and incredibly skilled. Thank you, All City, for sending someone with Sky's expertise and valueto my home. He's a true asset to your team, and I highly recommend both him and All City!

I called All City Plumbing, Air and Electrical because I had diagnosed that my furnace's blower…read moremotor and capacitor needed to be replaced. Jonathan came out and confirmed that that was indeed true. Everything seemed to be going well. Jonathan was very friendly and polite. When it came time for the estimate, he told me it was going to be just under $3,000. That seemed like quite a lot to me for just changing out a blower motor and a capacitor. He also told me that my Rheem furnace couldn't take just any old blower motor and he had to order one special. He said that his company doesn't deal with Rheem because their parts are hard to get. I reluctantly agreed to the repair, which he said would probably take place the next day. Later, he called and said the part wasn't going to arrive for a whole week. This was during one of the hottest weeks of the year in Southern California and I certainly didn't want to be without air conditioning, which runs through my furnace and needs the blower motor. I asked him what my other options were. He told me the only other option I had was to get a whole new system. He explained that he could install the system in only 2 days time or I could wait a whole week and have him repair the blower motor. He also mentioned a 10 year warranty with 1 or 2 years of service from his company. I asked him about the brand and quality of the Furnace that he intended on selling me, which was going to be almost $8,000. He told me it was better than my current system brand and I asked to get it in writing so I could do some research. After not receiving anything in writing I called his company and requested the same thing from them. Shortly after the conversation with his company I received an email specifying the make and model of the new furnace. I researched online and discovered a few interesting things. Number one, Jonathan had lied to me about Rheem parts. I found out from my online research that Reem takes Universal parts and I would not have had to wait until the next week to receive a blower motor that would fit. I also discovered that blower motors and capacitors cost nowhere near $3,000 to install. And finally, the brand of the new furnace that was recommended by Jonathan was nowhere near the quality of the Rheem furnace that I already owned. I canceled the job immediately with the company and again with Jonathan when he called me to find out what was going on. I am still waiting for my refund on the deposit! My contractor friend and I went to an HVAC store and purchased a universal blower motor and capacitor for $180... and installed it ourselves in a couple hours. The system is working perfectly. I don't recommend this business at all. I'm completely confused on why they have such a good rating on Yelp, which is why I picked them to begin with. This was a clear case of trying to take advantage of an old lady in a wealthy neighborhood. Shame on them!! Update: I received a full refund of my deposit and the service fee was completely waived. I got a nice apology from the owner and a manager.

These guys came out a year ago when my AC was not working. Technician Christopher came and looked…read moreat my system and quickly determined that I had no other option but to replace the unit with a new $20,000 unit. He called in his buddy, who came into my house and asked repeatedly "so you're the home owner?" "So you're the only one here making decisions?" "You're single?" He pushed me to buy a new unit and went over financing options. Told me if I signed that day they'd give a substantial discount. I felt that this whole interaction was pretty predatory. I told the tech I would need to think about this, and get another opinion. While the tech was here, he replaced a part to get the system working for the time being. They gave me an invoice for over 1000 dollars. I told them I'd need to have my dad look at the invoice and make sure I wasn't being over charged. The invoice was vague and did not list the parts that were replaced. I asked the tech to let me know exactly what was replaced. He wrote down a list, still pretty vague. My dad said that the parts replaced should have been around 400. Not over a thousand, and even with labor, this invoice seemed pretty unreasonable. I called the company back to discuss. They would not tell me exactly what parts they put in, and ultimately decided to drop the invoice completely. My assumption at this point was that they knew they were being shady. Fast forward to now. My system is freezing and not working properly. The tech from another much more honest company that came out today said that tests are showing multiple types of refrigerant, which could be causing my issue. I called year round to let them know that they should have drained the system before adding another type of refrigerant, and they maintain that they never added any refrigerant when they were here last. I think that this company is not taking accountability. I let them know I'd be leaving a review to share my bad experience. Shortly after I received a call from the owner of the company. He asked me to explain my issue, and when I did he denied that his techs would ever act in the predatory manner I described. I told him I did not wish to speak with him any more as he was not taking any accountability, and that this in fact was my experience, and I would be sharing it in hopes of protecting others. I hung up the call. HE CALLED ME BACK TO THREATEN LEGAL ACTION IF I "SLANDERED" HIS COMPANY! This review is not slander. This is an honest account of my experience with this company, and I will not be bullied into not sharing. I can't imagine how many of their customers have fallen for their predatory tactics. Honestly I feel pretty nervous that these guys have my address and could retaliate. Luckily I've got cameras and will be on high alert. This guy was pretty upset over the phone.

Ruben is a True Professional!…read more I recently had an issue with my home AC unit in Lake Elsinore that stopped cooling properly during this hot weather. RKM reached out immediately and sent Technician Ruben. From the moment Ruben arrived, he was courteous, professional, and respectful. He thoroughly diagnosed the problem, explained everything in clear, easy-to-understand terms (no technical jargon overload), and got right to work. He replaced a faulty capacitor and performed a full system check to make sure everything was running perfectly. The repair was completed efficiently, and my AC is now blowing ice-cold air. Ruben even took the time to show me a couple of maintenance tips to help prevent future issues. I'm extremely impressed with his knowledge, speed, and friendly attitude. Kudos to Ruben for his Great service and professionalism. He's a top-notch technician who clearly takes pride in his work. Thank you Ruben!
