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.

These guys are amazing--professional, knowledgeable, and incredibly thorough. They take the time to…read moreproperly diagnose the issue and find the right solution instead of immediately trying to sell you a whole new HVAC system unlike some other companies. I really appreciate their honesty, expertise, and commitment to doing what's best for their customers. Highly recommend!

Gary came out right on time, called twenty minutes before arrival letting me know that he was on his way in a company truck, and not only replaced two thermostats, but also replaced a worn out rusted compressor. He had all the parts I needed to get both of my systems running great. He worked fast, didn't wear too much cologne, and had a mellow cool demeanor. He was the type of guy who won my trust quickly, as did the company. Thanks All City for a job well done, knew what to do, handled quickly, and had all the parts needed.

When our AC went out on a Thursday…read moreduring the summer heat in Fontana, I started looking for a company with a strong reputation and consistently good reviews. Steve's Five Star Service kept appearing on my list, and after my experience with them, I completely understand why. Angel came out that Saturday for the consultation. He was professional, knowledgeable, and honest about what our home needed. He carefully explained our options and walked me through the entire process, so I always knew what was happening and never felt left out of the loop. I also really appreciated the text updates letting me know when the technicians were on their way. The arrival times were accurate and made everything much easier to plan. By Tuesday, José, Jessie, and Brad arrived around 9:00 a.m. to install our new 3-ton high-efficiency heat pump system. They kept me updated throughout the installation, answered my questions, and completed everything by about 5:00 p.m. Their professionalism, communication, knowledge, cleanliness, and attention to detail were outstanding. The installation looks clean and organized, and they treated my home with respect. The price was reasonable, and most importantly, the new system runs amazingly well and is very quiet. Our home is comfortable again, and they made what started as a stressful situation much easier for my family. A huge thank-you to Angel, José, Jessie, and Brad. Steve's Five Star Service should be proud to have employees like them representing the company. Their hard work and the way they treat customers deserve to be recognized. Honestly, this entire crew deserves a raise. I would confidently recommend them to anyone needing heating or air-conditioning service.

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

Plus the air filter was dirty and all it was to blame was a contactor relay in the AC condenser which only cost us $30 plus a from Amazon. plus a new Filter for about $20 and we were up and running.

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.
