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 really appreciate their honesty, expertise, and commitment to doing what's best for their customers. Highly recommend!

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!

We hired this company to repair a water leak and replace our water heater. While the leak itself…read morewas eventually fixed and the job did ultimately pass every city inspection, the process took about a month longer than it should have and cost us real time, stress, and lost work -- issues we feel other homeowners should know about before hiring. Work began July 5th with tank removal and drywall demo by Collen S. and his partner. The next day, they repaired the leak by replacing about 6 feet of PEX line, and a subcontractor patched the drywall. About 20 minutes after the patch was done, Collen S. told us the new water heater install was good to go. We specifically asked whether a permit was needed -- for both the leak repair and the water heater install -- and Collen S. and his partner told us twice that day that it wasn't. We requested one anyway. That turned out to matter a great deal. On July 14th, Collen S. gave us only about 30 minutes' notice before the inspector arrived, even though we had asked him to give us a day in advance so we could request time off work to be present. The inspector arrived anyway, and when we asked directly, he confirmed that both the water heater installation and the PEX line replacement had been done without the required permits -- meaning both jobs were effectively illegal until they could be properly permitted and inspected. This flatly contradicted what Collen S. and his partner had told us twice on-site. The next day, we called the company's manager, Steve, and raised three concerns: the contradictory permit information, the last-minute inspection notice, and our request for a different crew going forward. On July 21st, a new tech, Michael, introduced himself, and the City of Eastvale inspected the drywall repair. The city did not approve it and required the wall reopened for a mold check. Michael returned that same day to reopen it. On July 27th, the city inspected inside the wall, confirmed no mold, and approved the space to be patched and the water heater reinstalled. Drywall repatching happened August 3rd, and the final inspection closed everything out August 6th -- roughly a month after the leak repair began. On top of the permit issues, we were also pressured more than once to buy add-on services unrelated to our leak. Collen S. showed us "dirty" pipes at least twice in what felt less like genuine advice and more like an attempt to play on our emotions to drive a commission-based sale of a whole-house filtration system. He also pushed a full home re-pipe on separate occasions -- again, unrelated to what we'd actually called about. To be fair, the leak repair itself was solid, the city inspectors were thorough, and the job ultimately passed every inspection with no mold found. But getting there cost us two additional days off work -- one for the re-inspection that was only necessary because permits weren't pulled correctly from the start, and one for the wall re-closing after the unapproved drywall job had to be reopened -- plus significant back-and-forth to sort out miscommunication that should never have happened. We're hopeful the company will work with us to make this right, since the repairs themselves held up -- it was everything around them that fell short. A crew not knowing (or misrepresenting) basic permit requirements, and using emotional pressure tactics to upsell unrelated services, are things we don't think any customer should have to tolerate -- and we'd encourage this company to address both with its technicians directly. Because of the permit miscommunication that left our repairs technically illegal for over a week, the last-minute inspection scheduling, the repeated upselling pressure, and the extra days off work it all cost us, we cannot recommend this company.

From routine maintenance to service calls, they've always been professional, honest, reliable, and incredibly knowledgeable.

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.

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

I'm extremely happy that I chose Steve's Five Star Service. 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.

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.

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.
