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!

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.

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.

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.

He was completely honest about the cost of me DIYing it versus what he would charge, and that kind of integrity is rare. Dave was patient, kind, and had amazing interpersonal skills. He could have easily come out, billed me, and called it a day, but instead he helped me troubleshoot everything without rushing me. Because of that, he earned my future business and all my referrals. I'm even sending him a thank you through Venmo because he truly deserves it. I wish him nothing but good karma. If you need someone trustworthy and genuine for HVAC work, call Sims Comfort Solutions and ask for Dave.

The highest praise for Steve's 5 Star Service! I'm absolutely astonished with their service and so…read morehappy I chose this company to handle my HVAC replacement. 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
