It's rare to find a company that consistently delivers outstanding service year after year, but Diamond Air Services does exactly that.

When Isaac arrived, he took the time to troubleshoot my issues with me, and we quickly got to the root of the problem with my unit. He also walked me through all of the options I have for my unit, and provided me with a hassle-free experience. I really like their family membership program and signed up for that, so I plan to continue doing business with them because this was a great experience. I definitely recommend giving them a shot for any of your HVAC needs!

I had a great experience with All City Plumbing & Air, especially with Johnny, the technician who…read morecame to my home. Johnny was very kind, patient, and professional. He took the time to carefully look around and figure out what was causing the problem instead of rushing through the job. I had contacted other companies before, but it was sometimes difficult to understand their explanations, and I didn't feel like I was getting clear answers. Johnny was completely different. He explained everything clearly and patiently, making sure I understood what the problem was and what my options were. I also really appreciated that he explained the cost upfront and let me know about things I wasn't aware of before starting the work. There were no surprises, and I felt comfortable knowing exactly what was being done and how much it would cost. Johnny was not only knowledgeable and professional, but also very kind and easy to talk to. He answered all of my questions and made sure I understood everything. I'm very thankful for his help and the way he treated me with kindness and respect. I would definitely recommend Johnny and All City Plumbing & Air to anyone who needs plumbing or air conditioning service. Thank you, Johnny, for your excellent service and for taking the time to help me understand everything!

I highly recommend Gabe Smith and All City Plumbing. Gabe is extremely knowledgeable, highly…read moreattentive to detail, and delivers outstanding quality work. From the start, he took the time to explain his entire process in detail so I could easily understand exactly what he was going to do. We hired him for a significant amount of work, and he handled all of it flawlessly. He replaced our kitchen sink, garbage disposal, and the angle stops around our bathrooms. He also installed a brand-new water heater, a Flow Tech anti-scale system, and a thermal expansion tank. Additionally, he replaced the main faucet and pipes connecting our house to the city water supply and successfully fixed our home's water pressure, which had been running dangerously high. What truly sets Gabe apart is his customer service. He is incredibly friendly, attentive, and kept in constant contact throughout the entire project. He is completely transparent and never acts like a pushy salesman; he simply assesses the issue, states the exact cost to fix it, and gives you the space to make up your own mind without any pressure. I would absolutely hire Gabe Smith and All City Plumbing again.

I want to thank Jon and the team at Metz Air Control for making things right. I had an issue with…read moremy AC freezing and there was some confusion about what was included in my VIP Membership. Their website listed evaporator coil cleaning as included, but the office said it was extra. I sent a screenshot, Jon personally responded, thanked me for catching the error, said they would fix the website, and honored it at no extra charge. They came out today and thoroughly cleaned both my condenser and evaporator coils with no extra charge. It's refreshing when a company actually stands behind what they advertise. Thank you Jon for the great customer service and for getting my system back up and running. Family owned since 1977 for a reason.

I've been using Total 1 for several years now, and they have consistently earned my trust. Over the…read moreyears, I've dealt with multiple contractors, and too many of them immediately jump to recommending a full system replacement without taking the time to truly diagnose the problem. That has never been my experience with Total 1. What really sets them apart is their honesty and attention to detail. Instead of "firing the parts cannon" or condemning a perfectly serviceable unit just to make a bigger sale, they focus on finding the actual issue and fixing what truly needs to be fixed. That approach has saved me money and given me confidence that I'm getting straightforward, professional advice. Every interaction I've had with Total 1 has been positive -- they're knowledgeable, respectful of your time, and clearly care about doing the job right. It's refreshing to work with a company that prioritizes long‑term customer relationships over quick upsells. In my experience they have always been a great value. If you're looking for a contractor you can trust -- one that won't pressure you into unnecessary replacements and will take the time to explain what's really going on -- I highly recommend Total 1. They've earned my full endorsement and will continue to be my first call.

I will definitely be using them in the future for all my ac and heating needs. Thank you!

We were recently faced with the harsh reality that our original 24 year old A/C needed replacing…read more With that I began my search for a reputable company in my area. I saw all the amazing 5 star reviews for True Blue and noticed a common theme. Honest, fair, professional, informative, nice, competitive pricing. All 100+ very positive reviews and not a single negative review. As we all know, that's essentially nonexistent when dealing with the public in any capacity, particularly when it comes to the HVAC service industry. I gave them a call to schedule an estimate. Lisa answered and was amazing with accommodating my schedule and with all subsequent correspondence. Shane came out a couple days later, educated me on the new systems, patiently answered all my questions and took his time explaining in detail my options (I ended up going with the Bosch/heat pump. Quietest compressor I've ever witnessed). Shane sent over a quote that was less than another quote I had received and with many more upgraded options including a $2K federal tax credit. Much more overall value for my money. Shane's crew (Kevin, Rudy & Brandon) came out on the scheduled date and time and handled business to perfection. Removed my old stuff, installed the new equipment and made sure everything was working flawlessly before leaving that same day. The enter process was seamless. Like so many others, I can't recommend Shane and True Blue Heating & Air Conditioning enough for anyone looking to replace their HVAC system. There aren't many small, family owned businesses like this one any more.

I am sharing this review to help other homeowners know what to check after having a new HVAC system…read moreinstalled. NexGen installed my system about one year ago. When the air conditioning stopped working, they told me the circuit board needed replacement. They said the part was under warranty, but I would still pay approximately $500 for the technician. I then spent nearly two months without working AC while waiting for this supposed repair. I finally called Southwest Heating & Air Conditioning for a second opinion. They came out, identified the actual problems, and restored the AC during the same visit--without replacing the circuit board NexGen said I needed. Southwest's written inspection documented several serious concerns with the original installation: * The system had been installed without an air filter. * The filter housing had been taped completely shut. * There were multiple wiring problems, including the system being wired incorrectly. * The plenum was leaking. * The ductwork was not adequately sized for the five-ton system. * A wireless sensor should have been installed on the third floor to help regulate airflow. * Additional repairs are still needed for the system to operate as it should. My advice to other homeowners: Do not assume an expensive part is the problem or wait for months without AC. Get a second opinion and ask the technician to check the filter housing, wiring, plenum, duct sizing, airflow, and sensors--especially after a new installation. I also had a similar pricing experience with NexGen's plumbing department. They quoted approximately $4,600 for work that another licensed company completed for about $860. After an incorrect diagnosis, two months without AC, poor communication, installation concerns, and extremely high pricing, I cannot recommend NexGen. I was also advised to report this matter to the California Contractors State License Board.

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!

They provided white glove service from quotation all the way through installation. I was simple to book a same day inspection and quote request for a new HVAC unit online. The repair technician Angel Perez was just that, an absolute angel. He was unbelievably kind and knowledgeable. After meeting with him and hearing him speak to other members of the company over the phone, I knew this was a special company. The employees spoke to each other like family. Once I submitted my signed contact online, Angel thanked me for choosing them and welcomed me to the family. Contract provides excellent warranty on parts and labor. Unit included install of ecobee smart thermostat, which I am in love with! Not sure how I got by all this time without one. By far the best quoted price out of the four I received. On the day of installation I received a text update with a photo and name of the lead installation technician Jon Neves. He and his team arrived right now time and finished the work exactly at their provided estimated completion time. The team placed a mat by the front door entrance to my house, which was a very nice touch, covered carpeted areas where they would be walking. After the job was complete they vacuumed their work space and it was like they weren't even in the house. The group of guys working in the installation took great care in everything they did. My installation required a crane to get the unit on top of my house and The Purple Crane was in and out quickly. The crane didn't disrupt my neighbors or even the trash service that morning. The crane was in and out in less than 30 minutes. Highly recommend Steve's 5 Star Service. They offer a service membership for less than $20 a month to handle HVAC tune ups, water heater flushes, and any service needs. You read that correctly, they also do plumbing! They will now be my go to for any plumbing needs. I'm due for a new water heater and I will be contacting them in the near future to handle my replacement. Steve's 5 Star Service took such great care of my baby girl and I during the heat. They were urgent to get us some reprieve from the heat and cool air into our home again. They are the nicest group of people I've ever hired. True to their word, take great pride in their work, take respectful care of their customers and provide easy breezey service. Shout out to the wonderful team that assist me on this project: Angel Perez, Jon Neves, Brad, Javier and The Purple Crane. Thank you thank you! I cannot thank you all enough! It was a pleasure working with you. Breana Cumberland Smith Chino, CA
