What Your Neighbors Say After We Leave

Had a massive undetectable leak in a new home I just moved into... I was losing 1000+ gallons a day and was so worried about what was going to be the outcome. Then Radiant/ DAVID FARMER my saving grace, best plumber I've ever had, came to my rescue. It was a large job with doing all the leak detection and solving each problem but David was kind enough to teach me everything he was doing/what to look out for in the future to avoid issues later. It was an awful stressful situation that he made easy and fixed quickly. I think they are fairly priced and will work with budget constraints if needed. All I know is I know who my plumber is for life and I really appreciated all that Radiant and David did! UPDATE: used radiant for a AC repair and again they didn’t disappoint! April was my technician and she was AWESOME! So patient and kind and I learned a lot about my system that she showed me! Kudos again Radiant!!

We had another incredible experience with Radiant Plumbing & Air Conditioning that left us very impressed. Back in 2013, we hired this exact company to replace our old water heater, and the entire experience was absolutely outstanding. So, as soon as we realised it was time to replace our 2013 water heater, we didn’t hesitate to contact Radiant once more. Once more, Radiant and Christian, the technician, exceeded all expectations with their efforts. Christian is a true professional. We appreciated how Christian clearly explained all the different choices and worked hard to keep us near our budget limits. Our sincere thanks go to Christian and Radiant for their genuine support in helping us remain as close as possible within our financial limits. Christian was not only kind but also very respectful during his time at our house, and he did an outstanding job. Christian and the gentlemen who accompanied him performed their tasks excellently, demonstrating friendliness, kindness, and deep knowledge of their craft, which clearly marks them as true professionals. I want to express my gratitude to Radiant and also to Christian, thank you both!!

If you're in need of a new HVAC system because the one you got from the new home builder has broken down or is not working right, especially in this heat wave, Radiant can get you setup with a new and energy efficient system that keeps you cool and comfortable no matter the extreme temperature outside.

I highly recommend Radiant for cooling and heating. They are very friendly, knowledgeable and professional.

Their technician (Nathan B.) was outstanding and Breana the customer support manager provided stellar service and support.

They even have an annual warranty service program where they come out twice a year ahead of the winter months for heating system checkup along with system maintenance and then again in springtime to check the cooling ahead of the summer months for cooling system check and and any necessary maintenance to keep your system running efficiently and smoothly.

There warranty service is much cheaper than American HomeShield and does not require a copay or deductible. It's quite a bargain and it provides peace of mind.

Give Radiant a try and your heating and cooling worries will disappear. I absolutely recommend them with the highest rating available.

I have used Radiant off and on mainly for plumbing for past 20 years and didn't realize they did HVAC for some reason. Well today in one of our units - the AC fuse went out / and other issues here in Austin where the temp was climbing to 89 inside. Thinking no one would come for Labor Day weekend (I had called some existing HVAC - and there was no response). Radiant provided a person within two hours of calling. Paul Dugas the technician made the fix and suggested some other options. That being said Radiant/Paul was thorough and he spent 2-3 hours replacing a capacitor / fuse. I would highly recommend Radiant as they are reasonable per market rates and for those that have investment properties and need to manage remotely - one can count on them. Hope this review is helpful. I was thinking I had to swelter until Monday. As for Paul Dugas - though I am sure other techs are great.

Hands down the best experience with home service and support that I’ve received in a long time.

My water heater was way past its useful life resulting in a failure that left us without hot water. Paul came out and diagnosed the situation in less than 15 minutes. He gave me multiple options for repair and replacement and gave me his honest feedback on the best course of action for my situation. We confirmed the replacement that we were going with, and he got the parts and installation scheduled for the same day. In parallel, Paul supported me with submitting the claim for warranty, including talking directly with the claims adjusters. An hour or so later, Tito came out and completed the installation quickly and seamlessly; the finished product is clean and the surrounding area is spotless. No issues since.

Paul’s expertise in the field as a master plumber gave me complete peace of mind as he was more than happy to answer all of my questions. We ultimately ended up with a brand new water heater before dinner time. Crisis averted.

Amazing! They actually just did what they said. We had a main sewer line stoppage it was on the weekend I googled who to call an ad for radiant popped up with a special coupon for drain line cleaning. I called them a little bit hesitance because I just thought it was going to be a total baiting switch like I've experienced at other places in the past and they tell you the special price and it ends up being something two to three times that amount once they come out. They immediately communicated with me by text the technician let me know when he was going to be here he showed up he was polite told me this is all the charge was going to be today that they would take care of it and then if they found anything they would make me aware of what they found and we could go from there if there were anything. He handled the issue promptly unstopped the sewer line told me what he saw what his thoughts are on the matter and the total price was exactly what the ad said nothing more no high pressure sales tactics no oneing to sign an annual service contract the price was the price. The technician was friendly his name was Jacob goes by Jake we visited a few minutes about some common interest I will definitely use radiant in the future.

I received an abnormal water usage text from the city of Austin in the morning. I checked all my outside spigots and the main shut off where it comes in from the street and found water standing in the main shut off area. I called Radiant to see if they would be able to get someone out and they said they would be able to the same day. It was a very easy process for them to schedule someone to come out and that person contacted me within the hour and was at my house shortly after. That person was Marcel Lavalle and he showed up, listened to everything that I told him that I had found, I even asked further questions about concerns I had about different things around the house, he was very patient.
He answered all of my questions and then got to work on fixing the leak. After fixing the leak, he showed me what the problem was and explained what he had done to fix it and showed me all of his work. He then started working on another concern that I had and was able to fix that better than I had imagined in very short order.
I am very pleased with the professionalism and efficiency and timelines that Radiant and Marcel were able to provide me. I would highly recommend this company for anyone who has plumbing needs.

Fast forward several months and GFiber cuts an irrigation line under my sidewalk path on the side of my house (my property) on a Friday evening. It was too late for GFiber to get a plumber and we had to shut off water to the house because we weren’t able to turn off the irrigation. I called Radiant Plumbing and Dallas was at my house in under an hour. He took the time (it’s almost 9:00 pm and dark by now) to show me what is in each receptacle in my front yard and a trick I can use to turn the very right main water valve so I can do it myself when needed. He got the irrigation turned off after unburying the valve handles in one of the receptacles and I have water to my house again. (GFiber has so far been great and says they will reimburse.)

Kim was very helpful and empathetic when I called this morning about a leaking water heater in my attic. Preston responded was able to help same day and saw right away there was actually a small leak in my roof above the water heater, which he quickly remedied by getting in the roof and patching it! I also like that Radiant texted Preston’s photo and a short bio ahead of his arrival. Very impressed. If (when) I need plumbing or air conditioning help in the future, Radiant got a loyal customer today.

We had guests coming to stay with us and noticed that the bathroom in our garage studio was acting up. We initially called another company, they arrived and the tech explained that I had an issue that required roof access, something they don’t do. So I called radiant, and was pretty desperate at this point. Grant came and took a look at the situation and did not fully agree with my initial diagnosis. He gave me a clear overview of the best plan to identify the issue, and he then identified that the issue was not in the bathroom at all, it was in my main line. At this point it was pretty late so he assured me that they would come back out in the morning to resolve it. Grant came right back the next morning and went straight to work, but the clog seemed very stubborn, and something was not making sense. Trevor then came and brought a camera and started to ask questions about the work the city was doing with everyone’s sewer lines in the neighborhood- I gave him the run down, and he started to scope, and had a hunch. Turns out the city never tied in the line for our garage apartment into the new sewer line. They then outlined that the charge would be high to fix, so it would be in my best interest to get the city to come and fix it. Luckily they were still working in my area, so I flagged them down and Trevor and Grant showed them the footage, marked exactly where the connection is missing, and politely but assertively told the city foreman that his team should prioritize fixing the situation that they caused at my house and advocating for us. In the end, the city came back to our property completed the work, and did it in record time thanks to all of the info that the Radiant team provided. This all happened in the course of less than 24hrs. Had it not been for the radiant team… I don’t think this would have happened, especially based on my first diagnosis. Super thankful!

Service was excellent. Friendly on the phone staff and answered all questions competently. They even gave me discount on service call after i explained my situation. Tech that came over to check system (the same day i called them), Adrian Silva, went above and beyond helpful in explaining problem via photos he took cause I could not use attic stairs to go see the problem with him eventhough I did not asked him for the pics. Now, its still expensive to fix AC unit but they quoted me 1k less than another company I had previously called who in cedently I have dealt with for years and made me wait 4 days for appointment. And Adrian even showed me a simple maintenance trick I can do to keep ac unit lasting longer in this Texas heat. All in all, professional service with a friendly smile, but still hurt the wallet..........its this economy we live on now days I guess.

I’m extremely grateful for Radiant Plumbing & AC. Beginning with their booking and scheduling was very easy. A provider came out the next day, giving me a 45 minute notice prior to arrival. Juan Ramirez came out and was very professional and courteous. Before he began anything, he suggested a diagnostic to make sure that he could give me a good and accurate estimate by actually diagnosing what the issue was before beginning the work. I really appreciated this. After he found the leak, he called me out to look at the area and explained everything to me. He found that the leak was not my responsibility to repair. Prior to working with Radiant, two other companies came out and quoted me over $1000 to repair the problem when they had never actually taken the time to dig out and remove the debris and standing water to diagnose the issue. Juan thorough diagnostic and not being afraid to get dirty and get to the root of the issue saved me a lot of money. The $199 diagnostic was well worth it considering all of the work he did. Thank you so much Juan for the work you did and the detail report you provided! I will definitely be using Radiant for all of my plumbing and AC needs in the future.

We had a baby two weeks ago, and on Thursday our AC unit suddenly started dripping water onto the floor. My parents had just left after spending two weeks helping us with the newborn, so my wife and I were officially on our own as new parents for the first time. Needless to say, an AC problem in the middle of a Texas summer—with a two-week-old baby at home—was about the last thing we needed.

We already had an appointment scheduled for the next day with our previous HVAC provider, but when we called to explain that the unit was now actively leaking, they told us they couldn’t address the issue until the following Wednesday. That wasn’t going to work for us.

I’m originally from Austin and have known about Radiant for as long as I can remember. They’ve always had a great reputation there, and when I saw they had an operation here in San Antonio, I figured I’d give them a call.

I’m so glad I did.

I explained our situation, and within just two or three hours, Radiant had someone at our house. They diagnosed the problem, took care of it, and now I’m sitting here writing this review with our AC back up and running perfectly—for what I consider a very fair price.

What started as a pretty stressful situation for two brand-new parents turned into an enormous relief. The responsiveness, service, and overall experience were fantastic.

I know exactly who I’ll be calling the next time we need HVAC or plumbing help.

Thank you, Radiant, for taking care of me and my growing family. You earned a customer today. Oh, and of course shoutout to, Kelly, our technician who made it happen.

Our air conditioning suddenly stopped working this afternoon. Several companies couldn't send us a technician until tomorrow, but then I called Radiant and they were able to send us a technician this afternoon! I will be calling them first in the future! The technician, Wayland Thompson, came to our rescue on this very hot day, and he did an awesome job of fixing the problem so that our air conditioning is working once again!! He also answered the many questions I asked and did an excellent job of explaining things! We are very grateful to Mr. Thompson for his outstanding work, and we highly recommend Radiant! We will be calling Radiant for our repair needs. Thank you very much, Mr. Thompson and Radiant!!

I am adding another 5 stars to my review of Radiant for August 4, 2026. While he was doing his repair work, Mr. Thompson found that we had a related plumbing problem. He reported this to Radiant. Radiant then sent Mr. Abdias Castillo to our house to fix the plumbing problem. Mr. Castillo did an excellent job of fixing the plumbing problem, and he repaired some other plumbing issues that we asked about while he was at our house. Again, we highly recommend Radiant and also their outstanding plumber, Mr. Castillo! Thank you very much!!

Radiant is an absolute top-tier provider when it comes to their plumbing services. We had a stopped-up bathroom sink and after attempting to clear it myself with an auger, I wasn't able to clear it.

We called Radiant one afternoon and they showed up early morning the next day. Jacob was our plumber and spent a considerate amount of time in diagnosing and clearly explaining to us what the situation was. It turned out to be internal shearing of the old cast iron pipes that was causing the blockage. After getting on top of the roof and using a pin camera via the ventilation, we weren't charged anything after all of that work Jacob and his coworker had done, since it was determined by our landlord that he didn't want to go further with the repair process.

PLUS he got stung by 3 wasps while trying to access below our house to get to the pipes. Charged absolutely nothing after all of that! While we weren't able to get any service from Radiant this time around, that level of care and attention really speaks volumes for how well of a job Jacob and Radiant as a whole performs. If we ever have any other issues with our plumbing or otherwise, I know who I'll be calling for it.

Radiant Plumbing and Air Conditioning was already a company we used and trusted. So, when our AC unit stopped working on the day I was supposed to bring my husband home from the hospital after open heart surgery, I called them in a panic. Kylee answered my call with genuine compassion and although they had a full schedule that day (100 degree summer day), she worked us in. Andrew S. arrived at our home at the scheduled time and expertly identified the issue. Because he had all the parts he needed to make the repair, he was able to have us up and running in a hour. Once again, Radiant came to our rescue. Their commercials are funny takes on that but that is truly who they are--heroes in a crisis. We only call Radiant when we need anything HVAC or plumbing related. I recommend them for their personalized customer service, expertly trained and professional technicians, and premium products at a reasonable price. It's only Radiant for us.

I had been looking for a plumber for 3 days to come out and repair my issue. Either I couldn't get no one till following week. Others didn't accept home warranty or had to notify my home warranty 1st b4 they could wrk.on my matter, some wouldn't respond to any messages I would leave, anyway I called radiant plumbing at random they handle emergency situations ,but as most they r pretty busy too. Receptionist said she put me on a list and would call me ASAP when someone be available, not even 30 mins later they informed me a tech was on his way. I was ecstatic that I got some one that quick. So this guy Aaron arrived and was so friendly and answered my question that I had, very, very nice guy he complimented the job fast made sure things were running correctly b4 he left. Let me tell u Aaron made my stressing over my plumbing gone like that! He is a asset to this company, and to let u know plumbing can be expensive a fee for this a fee for that. But theirs was a flat out fee for everything, I'd recommend this plumbing company a higher rate than 10 if I could.

We had an excellent experience with Radiant Plumbing & Air Conditioning, especially our technician, Chris Randolph. He was professional, knowledgeable, and, most importantly, honest. He took the time to perform a thorough evaluation of our aging HVAC system, clearly explained what he found, and walked us through every option without any pressure.

I really appreciated that he didn’t just try to sell us an expensive repair. He was upfront about the condition of our 14-year-old R-22 system, explained the risks of repairing it, and gave us his honest recommendation that replacement would likely be the wiser long-term investment. That level of transparency is hard to find.

Chris answered all of our questions, treated us with respect, and made sure we understood the pros and cons of each option. Excellent customer service from start to finish. I highly recommend Radiant and Chris Randolph if you’re looking for an HVAC company you can trust.

Outstanding Service – Manny is a True Professional!

We recently had Radiant Plumbing out to our home in the Lakeway area for a water heater replacement and to address our whole-house water pressure issues. From start to finish, the experience was fantastic, and a huge part of that was thanks to our technician, Manny.

Manny was absolutely amazing – extremely patient, knowledgeable, and genuinely helpful. He took the time to walk us through all our options for the water heater, explaining the pros and cons clearly so we could make the best decision for our home and budget. He didn’t rush us or push anything; it felt like he truly cared about getting it right.

Beyond that, he also spotted and thoroughly explained a bad shower valve in our guest bathroom. He showed us exactly what was wrong, why it was an issue, and what we needed to do to fix it properly (including steps we could handle ourselves if we wanted). His communication was clear, professional, and kind – no jargon overload, just straightforward advice that made us feel informed and confident.

The work was done cleanly, efficiently, and to a high standard. Manny’s professionalism, courtesy, and willingness to educate us really stood out in an industry where that’s not always the case. If you’re looking for trustworthy plumbing service in the Austin area, Radiant (and especially Manny!) is the team to call. We’ll definitely be using them again and recommending them to friends and family.

Thank you, Manny and Radiant Plumbing – you made a stressful situation easy and stress-free!

If I could give Jacob Rose at Radiant Plumbing 10 stars, I absolutely would. Before calling Radiant, I was at my wit’s end. I had already paid another plumbing company to come out TWICE, and they completely failed to fix—or even properly diagnose—my issue. I was dealing with a massive headache involving my washer backing up, a tricky venting issue through my roof, and tree roots busting through my outside drain pipe. Other people had thrown wild guesses and massive price tags at me, leaving me incredibly stressed.
Enter Jacob Rose.

Jacob didn’t just guess; he came in and performed the most thorough, forensic review of my plumbing I have ever seen. He walked through every single possibility with me. What stood out the most was how deeply he CARED about doing what was right for our home and our family. He provided a true "white glove" experience. His communication and ability to explain complex plumbing issues in a way that made sense were completely unmatched.
In an industry where it is so easy to get taken advantage of, Jacob’s honesty was a breath of fresh air. Given what other companies had told me, he could have easily convinced me to buy a bunch of additional, expensive services that I didn't actually need. Instead, he solved this incredibly complicated problem, didn't upsell me on a single unnecessary thing, and left us with an extremely fair price that I feel great about.

To Radiant Plumbing management: Jacob Rose is an absolute MVP. He is incredibly valuable to your team, and because of him, you have earned a customer for life. Everything is working amazingly now. Literally could not have gone any better. 10/10

My AC went out mid Friday afternoon and my regular HVAC company didn't have availability until the next day. Radiant came out the same day and unfortunately my unit was D.O.A. and needed replacement. They had Bryan come out late into the evening; missing his son's baseball game, to get me scheduled for a new system. They even installed 2 window units to hold us over so we wouldn't die! Most notably, after I signed a contract, I found a competitor with a lower price and Bryan got it price matched to keep my business. As Bryan said, "people first"! ...What a perfect summation of my experience with Radiant. I'd like to thank Dillon, my technician, Bryan my salesman, and Joey & Nicholas my installers who exhibited the utmost professionalism, courtesy, expertise and care during all aspects of the project. An honorable mention goes to Waylon as well. Thanks team!

Aaron Taylor was very professional and polite. He was able to arrive on a very short notice and was very accommodating of our schedules and communication. Not only was he very thorough in explaining what was wrong with our plumbing, but he also gave us several options how to proceed further with honest concern of future proofing our plumbing situation. He managed to maneuver a very complicated set up that has been added on through the years and at the end, not only did he make the plumbing functional, his craftsmanship was careful and beautiful. He didn’t just hack the job to work, he was considerate that people live here and was mindful of our dignity and gave us a clean and beautiful solution. I never thought a plumbing job that required two access holes in two walls would end up as nice as he did it. Very good job. He represented this plumbing company so well that I will be recommending their services to anyone that I know that needs a job done. Thank you Aaron for being patient with my elderly mother and for not leaving until you made sure everything was in working order. We’re very grateful for this great and flawless experience.

We contacted Radiant for an estimate to replace 4 builder grade toilets with nicer dual flush units that we purchased. They were very responsive, scheduled promptly, and keep us informed about anticipated arrival times. They even provided a photo of the plumber, Nathan Burke, who was assigned to us. He went out of his way to lobby for a price reduction because we're planning to donate the original units to Habitat for Humanity rather than have Radiant haul them off. Install was scheduled for the next day, again by Nathan. He was friendly, courteous and professional, and got the entire job done by himself. He kept us informed of any additional work/supplies needed (longer supply hoses and re-orientation of a couple of valves). He cleaned up the work areas and hauled off the packing materials. Unlike some of the other service companies we talked to, he did not aggressively try to upsell other services.

The cost was higher than I initially thought the swap-out would be, but in line with the other estimates we obtained.

Dion went above and beyond searching for the giant-sized leak we supposedly had on our shared property. After spending yesterday investigating, probing, and diagnosing, he decided to bring in a second opinion, his manager, Mike today. Both scoured the area in and outside our buildings and found no evidence of the 13gpm leak. That was an unsatisfactory answer for them so they continued investigating beyond our buildings down towards the swimming pool. Without having contracting the city, they could not definitively state that it was leaking there, but there were signs that were more logically pointing to that. The entire time spent here yesterday and today, Dion completely explained all the potential problems we house, and even wrote up estimates to correct. However, not having located the leak, he and Mike charged a very reasonable amount for a full day's worth of work! They offered solutions and options for going forward with the help of the city. I cannot adequately put into words our appreciation for their patience (especially Dion, for 2 separate days!) and ability to explain what could possibly be happening, after ruling out all other reasons....Thank you, Dion! You truly are a patient, kind "teacher" and detective! Mike, your pleasant countenance and personality made our day! Thank you both! Mariposa Family Learning Center

I am so grateful that Radiant helped me. I had an issue where my hvac was blowing hot air. I live in 95 degree weather. I first had a tech from a different company show up and the other company told me the problem is the compressor and that the entire thing needed to be replaced at a cost of about $15K. I was upset, needless to say. But then I found Radiant.

I called Radiant on a 5 or 6 PM Monday night and they were willing and able to do same-day service (eta between "now" and 10 PM). I actually had a bunch of errands to do so I didn't take them up on it but I so wish I called them a day earlier when the issue started... anyway, we scheduled a visit for next day between 8 AM to 11 AM.

Radiant sent Wayland to my home and he arrived around 10:50 AM. By 11:30 AM, he had a diagnosis and it was a faulty wire and by 11:45 AM, the wire was replaced and I had AC again.

Also, Wayland was so respectful, kind, and had great energy. I signed up with Radiant for their maintenance program and I'm so happy to be in AC again!
