He was straightforward, honest, and gave no-nonsense recommendation, something I really appreciate. He quickly diagnosed the issue, replaced the capacitor, and suggested adding a compressor saver since our AC unit is nearly 20 years old. No pressure at all, just helpful advice. We decided to go with both and the pricing was very fair. Everything was done efficiently within an hour and our AC is running perfectly again. Highly recommend Marcel if you're looking for someone reliable, honest, and fast!

I noticed some mixed reviews, but after working with him, I realized he's just a straight shooter who gets the job done fast because of his expertise. He charges a fair, standard fee and doesn't play games. Marcel came out the next day and gave me a zero-pressure quote. Although my AC and furnace were from 1989 they were still technically 'working,' but I noticed the heater wouldn't always kick on and the AC would struggle. Marcel was honest and said they were fine for now, but you never know when units that old will finally go. I decided to change them now rather than wait for an emergency. Even though I just got the quote, he had an opening and was able to get the AC installed just two days later! A few days after that, I decided to do the furnace too. This is where they really shined: because of how that 1989 Carrier system was built, they had to do almost double the work to modify the setup they had just done for the AC. They came back with no issues, handled all the modifications, and put in the new furnace. Now, everything is running whisper-quiet and they cleaned up perfectly. The crew with Renee, Enrique, and a third helper were super fast and very respectful of my belongings. They answered all my questions. l always prefer to support small 'mom and pop' company instead of a big franchise. You get a personal touch you can't find elsewhere. If you want someone highly knowledgeable who understands your needs without pressuring you for extras, call Marcel. I'd highly recommend them to anyone.

    Money grab. I called for a simple clogged drain because I received a coupon in the mail for a great…read moreprice. Somehow the plumber ended up with a list of issues costing over$1,700! I felt like they were trying to pull a fast one on me, as a woman living alone. I also felt uncomfortable with him looking around my home and questioning the age of my ac unit and telling me that I should replace it with them (even though I said it was working fine). He also said I should replace all the piping in the house even though I've had no issues. I eventually called another plumber out and he did the job for under $500 and without hassling me. Be sure to always get a second opinion, especially if you decide to call Happy Camper.

    We had an excellent experience with Happy Camper from start to finish. From our very first call,…read moreall of our questions were answered clearly and promptly, which gave us a lot of confidence moving forward. Juan came out before the work began to walk us through the entire process, and we really appreciated that level of communication. The crew of four was always on time, respectful, and very courteous throughout the project. This was an emergency situation for us, and they were able to start the very next day, which made a huge difference. They also coordinated directly with the restoration company and worked seamlessly together. We are very happy we chose Happy Camper to completely replace our sewer system. Their professionalism and efficiency truly stood out. We highly recommend them!

I obtained three estimates, and ultimately chose Evolution. I did not regret this choice. Jeff Kieffer came out the day after I called and provided an estimate and a proposed plan, and the owner, Diego Martinez, visited my house twice, once to explain how a difficult room would be accessed and serviced, and the day the work began to answer any final questions and give final directions to the installation team. The process was smooth and efficient: * The team arrived on time, were extremely courteous, and Diego, the owner, showed up and took the time to explain everything clearly one more time. * They handled the installation with care, keeping the work area clean throughout the day. No mess left behind--they even vacuumed up and wiped down areas they worked in. * The crew was knowledgeable, answered all my questions patiently, and made sure the new unit was perfectly sized for our home (no shortcuts or upselling) * They tested everything thoroughly before leaving, walked me through the operation of the new thermostat (Ecobee Premium), maintenance tips, and warranty details. It's only been a short time since the install, but the difference in comfort is night and day. Exceptional financing was offered, and the value of this project was perfect for my budget I also gained a new closet by moving the unit up to the attic! If you're in the Orange County area and need a new AC/heater system, I can't recommend this team highly enough. Professional, reliable, and genuinely focused on customer satisfaction. 5 stars all the way--thank you for making our home so much more comfortable!

    Final update: The company has now stated in writing that they will not send a technician and…read moreadvised me to work with another HVAC company, despite acknowledging the issue may have fallen through the cracks. For context, during this period we had a newborn and significant personal obligations. When the visit occurred, the noise did not happen at that moment and no technician evaluation or adjustment was performed as a result. I later recorded the noise when it occurred and shared video evidence. Despite this, no diagnostic visit was offered. My review reflects both the unresolved issue and how it was ultimately handled. After posting this review, the business responded by disputing timelines and attributing the issue to unrelated work, but did not offer to inspect or resolve the ongoing airflow/pressure noise, despite video evidence. The attic cellulose work referenced was recommended by their team and performed by a contractor they referred. I had an air conditioning unit installed by Evolution Air in 2021. Since installation, the unit has intermittently made a loud "farting" or bubbling noise. I reported this issue within the first year. A technician came out, but unfortunately the noise did not occur during the visit, so nothing was adjusted or fixed. The problem has continued since then. After researching the issue myself, I found multiple discussions on Reddit indicating this is a known and common problem related to airflow or pressure adjustment, and that it is typically an easy fix for an experienced technician. Despite this, the issue remains unresolved years later. Overall, I'm disappointed that a known, recurring issue reported early on was not properly addressed, and that I've had to rely on online forums to understand what should have been a straightforward adjustment. I have recorded a video and sent it as well.

I decided to go with him to replace my 16+ year old AC condenser and coil after a major leak. He and his crew were professional, answered all my questions, and showed up on time in the morning as promised. They worked efficiently and finished by early afternoon. I also appreciated the attention to detail. The new condenser breaker box was smaller than the old one and exposed a nail hole and old paint, and his team took the time to fill it and use my paint to match the area. Very smooth experience overall. Highly recommend.

    You know they're legit when they can tell you the issue even before they look at your system…read more I contacted Dio in the morning and he got back to me quickly, letting me know that he can swing by same day. He and his son showed up and i described the issue (AC was blowing warm air but was working fine just a few months ago). His son checked my compressor capacitor, and just as he had said, it turned out to be the issue! They were able to quickly replace the capacitor and got my AC back up and running in under 30 minutes. Dio was extremely communicative, letting me know when he'd show up, and also had me try a few things before arriving. Also super fairly priced, and again, I'm very appreciative that he and his son were able to come resolve my issue during this heat wave!

With a few settings adjustments via that consult it held its own until earlier this month. Anticipating this year's heatwave it was a good thing that Fabian left his contact info on my phone. Quick call. Consult on Monday. Replacement determined to be the right thing to do. Not happy with the functionality, durability, brand of the six year old unit, a product upgrade seemed the best choice. Fabian left with a promise to do some research and follow up. Wednesday, same week, Fabian called with his product recommendation. Although costlier than the initial replacement quote, it was the right thing to do to insure maximum comfort. Installation scheduled for the following Wednesday. Technician arrival stated a 90-minute window. Team arrived within that time frame, donned booties to protect flooring, completed the process, removed old unit for recycling, even vacuumed installation area. Fabian checked in with his team while they worked. Collected payment. (Southwest HVAC accepts cash, check or card for payment.) Fabian reassured that should any issues arise to contact him. So far, so cool. Thanks to Southwest HVAC, their team and especially Fabian!

I was especially impressed with their communication and the level of commitment they showed throughout the entire process.Our system is finally up and running properly again, and I only wish we had chosen them as our original installer during our remodel. Instead, they came in and fixed what hadn't been done correctly the first time. Highly recommend! Longer version: Our system had been making a strange grinding noise every time we turned on the heat, and we could never figure out where it was coming from. On top of that, it took forever for air to reach the upstairs. The company that originally installed our system came out several times but couldn't identify the problem. After so many visits with no real answers, I lost confidence in their work. I started looking for another HVAC company and kept seeing great reviews for AARD, so I decided to give them a call. Scheduling was quick and easy, and they even offered a free inspection, which was a nice bonus. To be honest, I was a little skeptical at first and expected a quick visit followed by a sales pitch. That wasn't the case at all. When Joshua came out, he was incredibly thorough and took the time to carefully diagnose the issue instead of rushing through the appointment. He explained what he was seeing, gave us multiple repair options, and even changed our air filter for us before leaving. The next day we received a very reasonable estimate with several options, and once we approved the work they scheduled us within a few days after confirming the parts. On the day of the repair, Allen was the technician who came out. What really impressed me was that instead of simply replacing the motor -- which we initially believed was the problem -- he took the time to listen to my concerns and re-evaluate everything. It turned out the issue wasn't the motor at all, but the burner and a few other components. Even better, Allen came up with a smarter and simpler solution for reducing our zones that required less work and actually saved us money. He also coordinated with his management team to get the necessary parts the same day so the repair could be completed properly. He took his time, tested everything thoroughly, and made sure the system was running perfectly before he left. Overall, I'm incredibly impressed with the level of care and professionalism from AARD. It wasn't just the technicians -- the management team and office staff were also excellent throughout the process. It's rare to find a company that is this responsive, honest, and focused on actually solving the problem rather than just selling a repair. I would absolutely recommend AARD to anyone looking for trustworthy HVAC service.
