Thanks to yelp, I found Thomson Hvac The tech and I thought it should be a simple fix. He inspected my entire system, diagnosed the problem, and quoted the job. We moved forward with the fix, and it worked fine, and then it didn't. After a few more visits, and some more parts and tinkering, it finally started working properly. Although it was a strange and difficult situation, they stuck to it until the problem was resolved. The techs Danny and Mark went above and beyond to make sure everything was good. Another thing to add, the way the company communicated back and forth with me was great. They answered every call and every text. Most of the time I spoke with Stacey and she was great. If you're looking for an honest and professional company, this is it.

My mother recently engaged a service provider for routine maintenance on her air conditioning unit,…read morewhich included the installation of a new Honeywell thermostat. Subsequent to this service, she has reported that the air conditioning is not effectively cooling the premises, with only the fan operating. I advised her to adjust the thermostat to a lower setting. Given her advanced age of 90, her discomfort with the warm air became increasingly pronounced. Today, in collaboration with my brother-in-law, we investigated the issue. We observed that while the unit appeared to be functioning, it was not producing cool air, despite the outdoor fan operating correctly. During our investigation, we contacted the service provider, Thomson. A representative stated that only the thermostat had been replaced and that a service technician could be dispatched for a fee of $159, suggesting a potential wiring issue. Upon reviewing the Honeywell thermostat instructions and wiring diagram, we identified that the thermostat had been incorrectly wired to the "W" terminal. After rectifying this wiring error, the air conditioning unit resumed normal operation, producing cool air. I subsequently contacted Thomson for clarification regarding the initial service. Their response repeatedly referenced a previous replacement 14 months prior. While their online reviews are predominantly five-star, our experience suggests a lack of professionalism. This incident raises concerns about the necessity of recommended services and the quality of workmanship, potentially indicating errors or intentional oversights during the initial installation.

Juan was very personable and friendly I felt as if we already knew each other.

Can I give 10 stars to this company? My husband and I recently bought a new home a few months ago,…read moreand when we went to use the air-conditioning, it did not work. As you can imagine, as a new home owner, most all of our money was tied up in the purchase of the home and we were expecting the air-conditioning to work since it had previously passed inspection. I tried using our home warranty, but they gave me every reason under the sun not to cover it. At this point, we were so close to summer that we could not wait anymore, especially since we had a young child. I met with several air-conditioning companies for quotes, one that even quoted me over $50k for a new unit and ducting. I met with Kyle who worked with me on pricing. I really appreciated his calm demeanor, positive attitude and professionalism through this unexpected, stressful situation. He was able to fit us into their very busy schedule and we were able to get new AC up and running within one week notice. His team, led by Ivan, did a great job with the removal of the old ducting and unit, installation of the new and cleaned up after themselves after each workday. I also met Juan, on the last day who helped start up our system. Juan was kind, knowledgeable and professional. I had some minor hiccups that came up after the job was done, Kyle and Juan were very responsive and helped resolved things swiftly. They are an exceptional team and I would be happy to recommend them to anyone.

Scheduled an A/C tune-up with Advantage Air after a competitor (Nexgen) completely failed to appear…read morea week prior for the same job. The tech from Advantage, Mark, was great. Showed up 15 minutes into my 2-hour service window and before he set a foot inside my house, put covers over his boots which my carpets greatly appreciated. Did a thorough inspection of my furnace, air purifier filter, and A/C unit before cleaning the A/C. Said everything was healthy for an older system and didn't try to bullshit me or insult my intelligence. Guess which HVAC company I will never contact again and which one I would.

I called Advantage Air because my AC wasn't cooling. Their technician ran a paid diagnostic but…read morewould not open the unit, told me the refrigerant charge "seemed adequate," and proposed a coil cleaning of $545-$1,195 without ever looking into the system to see if it was dirty, to try to identify the problem. I got a second opinion. When the second company opened the system (originally installed by Advantage Air company), they found roughly two gallons of water inside the sealed refrigerant circuit, refrigerant leaking over the motor, a failed metering valve, an emergency water shut-off that wasn't connected and an unsecured exhaust line -- all documented with photos and video. The coil wasn't dirty; the system was contaminated and improperly sealed. I'd encourage anyone to get a second opinion before authorizing an expensive "cleaning," and to insist the technician show you what they're diagnosing. This system has only ever been worked on by Advantage Air. The system is basically new; it's eight years old. I purchased this home three years ago.

Absolut Airflow had quoted me the day before and their technician told me I needed a brand new furnace AND air conditioning unit!!!!! Fabian was honest and very knowledgeable and he saved me $20,000!!!! He is the best!!! If you want an honest technician, request for Fabian from Southwest HVAC!!!!

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.

Rebooked them again later for AC maintenance and a different employee showed up right on time for that appointment too, so it wasnt just a one time thing. What I appreciated most is how knowledgeable they were. They took the time to actually explain what was going on with the AC instead of just throwing terms at me. Ive had techs in the past be condescending or vague on purpose, but that wasnt the case here at all. Customer service was great throughout the whole process. This is going to be my go to for any AC or heater issues from now on. Thanks Andrew and Peter!!
