Justin the tech arrived and within 5 minutes he identified the problem and solution. He throughly explained everything and showed me the DAT was broken. He was able to replace and fix the system within 30 minutes. He was full of knowledge concerning HVAC with lots of tips and information about my system. He even invited me to take a look in the attic and explained some of the features. Another example of outstanding customer service far beyond what was expected. Will definitely call Advanced for any further HVAC problems.

From my initial interaction with the office representatives (Taylor, Dave Sr., and Dave Jr.) to the technicians who came out to my home (Nick, Jackie, and John Paul), the level of professionalism and care was outstanding. The team provided an in-depth assessment and diagnostic of all identified issues. Just as importantly, they took the time to clearly explain areas that were not a concern and documented a thorough review outlining why those aspects of the home were in good condition, information that will be extremely valuable for future home inspections or potential buyers. Each team member was knowledgeable, responsive, and thorough in addressing my concerns, making what could have been a stressful situation feel manageable and well-handled. When people speak of organizations that deliver top-tier service, this is exactly the kind of company they mean. AirCo has earned my trust and will be my first call for any future needs.

We did not purchase an entire new AC system/compressor/furnace with Jon Paul M. for the following…read morereasons: 1. He charged $675 to fill coolant and run a leakage test when he knew there was a 90% chance beforehand my evaporator coil was leaking and it would not be worth replacing the evaporator coil for $4500. He only offered a $675 credit towards a new system after I complained. 2. When I texted him a question about the new system quotes last year, he ghosted. Yet he emailed me four days later asking if I was ready to purchase a $17k system. Four days to decide on a $17k system without answering questions or receive other bids is not enough time. He cares more about making the commission than answering questions. 3. Jon Paul kept pushing the top of the line variable Daikin for $17k. Yet Shields AC & Heating in Lockhart said the DH7VSA compressor has a lot of firmware and software bugs communicating with the thermostat. Shields said it's not worth all the rebates and incentives. 4. Airco only offers a three year labor warranty through Airco. Yet they do not tell you that Daikin and Goodman offer an extended ten year labor warranty through Asure for $850. Daikin owns Goodman. 5. Jon Paul's quote did not include new return and supply plenum, unless he didn't specify. He only mentioned spraying the existing supply plenum with mold killer. 6. Jon Paul did not suggest moving the entire system 3 - 4 feet in the attic to reduce static pressure. Three other companies suggested moving the entire system. 7. When I asked Jon Paul what the difference was between the $17k variable Daikin and $15k variable Daikin, his response was, "More features and stuff." I need someone more articulate. 8. Jon Paul did not run a Manual J test. Ultimately, we ended up paying $12.1k with Jurnee Mechanical for a variable Goodman GXV6S condenser which included new return and supply plenum, moving the entire system 3 - 4 feet in the attic, 10 year extended labor warranty through Trinity, free maintenance for two years, and Reme Halo UV light.

He recommended me the best option and on March 25, 2026 year his co-worker Nima installed the new system. I was very lucky to choose this company because Alex and Nima really care for their customers. When later I found that the new thermostat was not proper working ,Nima came next day after my call and replaced at no cost with another model, which works well. Highly recommend this company and my best wishes to Alex and Nima.

It's been a pleasure, and I'm sure it will continue to be one. Thanks guys!

They took the time to thoroughly clean the condenser and ran multiple tests on the attic unit to make sure everything was operating as it should. What really stood out was how they walked me through the entire process at the end, showing photos and explaining each step. It gave me a lot of confidence in their work and attention to detail. I'm very happy with this company and would highly recommend them.

**1/5 Stars - Big Waste of Time (and almost a lot of money)**…read moreI wanted to like Service Wizard, but my experience with them was incredibly frustrating. My AC condensation pipe was completely backed up and needed to be flushed. Their tech arrived on time and seemed very professional, spending about an hour and a half working on the unit and inspecting everything inside and out. However, he couldn't find where the evaporator line exited the house. His solution? Install an external pump and run a whole new drain line. The rough estimate for that was, well, a hell of a lot more than the $15 fee they charged me just to come out and take a look. When he left, I still had the exact same broken AC, was stressing over an exorbitant bill to fix it, and somehow found out I'd been signed up for a $15-a-month service plan that entitled me to another check-up in six months just in time for winter. Hoping to just get it resolved, I reached out to Service Wizard via Yelp later that evening to see if they could come back today to do the work the tech recommended. I never got a response. Frustrated, I called a different AC company. They actually answered the phone, sent technicians out right on time today, and those guys spent **five minutes** at my house before finding the external line, repairing it, and flushing my system. Problem completely solved in under five minutes, and the fee was incredibly cheap compared to the massive quote I got from Service Wizard. I will definitely be canceling my $15-a-month contract with Service Wizard and won't be recommending them going forward. Save yourself the headache and call someone else!
