What Your Neighbors Say After We Leave

I would love to extend my sincere thanks to Radiant Plumbing, and especially to David Farmer, the technician who came out to care for my home.
From the moment he arrived, David carried himself with kindness, confidence, and an easy professionalism that immediately put me at ease. He generously shared his knowledge, explained everything in a clear and thoughtful way, and conducted a thorough investigation to ensure my home was running smoothly from top to bottom.
I was concerned I might have a leak, and David took the time to check every possibility, never rushing, never dismissing a question. He did end up replacing a plumbing fixture on my hose bib and walked me through exactly what he was doing and why—step by step, with patience and care.
I couldn’t be happier with the level of service I received. More than fixing a problem, David gave me something far more valuable: peace of mind. He made me feel safe, informed, and completely confident in the work being done.
I truly look forward to any future interactions, knowing my home is in such capable and trustworthy hands.
I want to sincerely thank Radiant Plumbing for employing exceptional professionals like David Farmer. The level of care, knowledge, and integrity he brought into my home speaks volumes about the company as a whole.
Because of this experience, I will absolutely be using Radiant Plumbing again in the future. Trust like that is earned—and Radiant has earned mine.

We had an ugly mess of decaying, cracked, and broken cast iron sewer lines under our foundation. After considerable research and multiple estimates, we chose Radiant to complete this extensive and expensive project because we trusted them. They did our HVAC replacement and our water heater replacement in years past. Each phase of the sewer line replacement was completed quickly and efficiently: excavation, removal of the cast iron, replacement with PVC, city inspection, and backfilling. We had a project leader (Ashley) available to us via phone/text through the entire process and she was "on it." They worked with our schedule...putting the inspection and backfill on hold while we were out of town, and even moved leftover dirt from the backfill to our backyard and smoothed it out. There were no rocks, cement clumps, or ugly dirt piles anywhere in the yard when they finished. Yes, it was an expensive (and necessary) project. This team is worth it! Thank you to Atanacio, Trevor, John, all the worker bees, and Ashley for a job well done!

I recently discovered that I had a massive water leak on my property due to an incredibly high water bill. I went ahead and contacted Radiant and another company to see if either of them could find the source of the leak and to get a quote on a repair. The other company told me that they couldn’t find the source but was recommending that I completely reroute my water lines to the attic, which they quoted $15,000-$20,000! I was in shock. However, Erik Stratton and his apprentice Mason, from Radiant came by and he was able to completely find the source of the leak (two areas). He was able to thoroughly explain the situation and was able to fix both leaks the very next day, for a fraction less than what the other company quoted me. His 24 years of experience really showed and I am glad that I went with Radiant!

I had an issue come up a couple days ago that involve drainage and a sensor on my AC unit. I called radiant they said they can get someone here Monday late afternoon and I said OK sounds good. AC was still working. I got a text message yesterday they said they can move up my tech appointment to this morning, I said great. The AC technician showed up and immediately went to work, listen to my concerns, showed him what I saw and showed him how I tried to fix it. (Which I would not try to fix it again 😎). It took my professional technician, literally 30 minutes or less to figure out the problem. Recommend a solution, formulate a plan get my approval and order the parts and install them. I cannot begin to tell you how comforting it is knowing you have reliable company that hires, extremely professional courteous, employees that not only exceeded my expectations, but strive to make sure they do the job right the first time

Radiant Plumbing and AC has convinced me there are still good companies out there that do quality work and care for their customers. I came across this great company called Radiant at a Home and Garden event. Got on their affordable maintenance plan. From there, I was able to get both my plumbing and AC checked on a same day schedule. I was so satisfied with the plumbing and AC technicians. Hector Hernandez , Ryan Hestand, Vincent, and Derek Lynn were so professional and very thorough with explaining everything they performed. AC diagnostic was explained and AC cleaned, Plumbers checked all pipes and flushed the water heater tank. We did decide to install a new a/c system and the a/c technicians did a fantastic job. They were respectful of your time, explained everything that was done. and left the entire place clean. Also Justin with the finance application was also very professional and thank you for saving us money, I would highly recommend Radiant as your AC and plumbing needs.

Nothing is worse than waking up to find that your air conditioner/heater unit died overnight leaving the house at 90 degrees plus. Thankfully Radiant Air Conditioning was available, same day, to save our sanity. We met with Don first to figure out the best solution to repair our 10 year old unit expeditiously. It was decided that it was best to just replace everything or else end up needing to replace the whole unit within months most likely. Don called in Bryan to go over all the options and help us decide what units we needed. Such fantastic information made it obvious that we were in good hands and picked a very affordable replacement unit.

Next step, Terrell and Pablo, installation technicians, were sent to pick up the new unit and complete the install. Both of these gentlemen were very helpful and made sure that we knew exactly what was being installed. After 7 hours the guys managed to replace the unit in the attic and the fan in the yard. A new Ecobee thermostat was also installed. We can't thank these technicians enough for guiding us along the way and being just great people in general.

We will definitely refer any of our friends or neighbors to Radiant if they need help with their

Our 30-year-old HVAC system finally failed last week, and I reached out to Radiant for assistance. They had a technician on-site the same day to assess the situation. From start to finish, every member of their team was professional, courteous, and transparent about what to expect throughout the process.

Shiloh provided a clear and honest assessment of our system, while Jacob walked us through several replacement and upgrade options, including solutions to improve the air quality in our home. I truly felt that both had our best interests in mind and were focused on helping us make the best decision for our family.

On installation day, Louie and his team arrived promptly, worked efficiently, and maintained a high level of professionalism. Louie took the time to explain our new system thoroughly and ensured I understood how to use the WiFi-enabled thermostat before they left.

Over the past decade in my home, I’ve had three other HVAC companies service our system through a home warranty. Each provided only temporary fixes to keep the system running. When it finally reached the point of no return, I chose to place my trust in Radiant’s reputation—and I’m glad I did. The entire experience confirmed that choosing Radiant was the right decision.

Radiant Plumbing and Air Conditioning never fails to excel. Their process, precision and people make the difference between just competent and exceeding my expectations.

Recently, I woke up to a small puddle of water- drip from upstairs. Radiant to the rescue, and in short order- on time and on point. IMPORTANT: Every thing you read next happened in 2 1/2 days.

Anthony from plumbing came out. Although I needed service on things like line flushing and tankless water heater adjustments, plumbing itself was fine. But? Drips continued…

Next was Sami-HVAC diagnostics and estimates. He gave me all information necessary, ranging from a “Bandaid” approach to full replacement.

Jacob from sales, up to bat. Radiant is there to meet a customer where they’re at, not force things in that your budget can’t handle. I chose full replacement after considering a bit of a fix to a system 5 years out of warranty.

Next day installation. Yes, all day. Renee was on point with Arturo at his side. They had the old system out just as the new equipment came onsite. The only issue was “where’s the other damper hiding?”. Renee found it, and careful placement of my unit now makes it a breeze for future techs to find when it’s time for maintenance. Diligent, precise and excellent work. Carlos slipped in at some point to confirm all was well. Thanks!

By 6PM-ish, air was flowing and cooling my house fast. Thank goodness, since it’s 100 degrees today.

My hat’s off to all at Radiant, including Janis (Janice? iPhones not always the best translator) who helped me follow up on some paperwork.

I highly recommend the entire organization. Thanks folks!

Radiant does the job that no else can. My AC was found dead at 6:42pm on a Friday when I got home from work. It was 82 degrees in the house and rising. I had to get a hotel room for the night because the company that normally handles HVAC issues sent texts saying that "they would be back in the office on the following Monday". Radiant not only charged a rock bottom diagnostic fee ($39.99 which is rolled into any work that is need and as compared to ARS wanting $99.99), but they put me on the emergency list for service that very night if a spot opened up. Unfortunately one didn't but they were here right at 9:30am the next morning and had an answer for me (along with an excellent detailed estimate combined with actually showing me the specific issues). I also want to give a shout out to HVAC Tech Jason Barta who was the tech that assisted me. He was extraordinarily prepared and skilled at diagnosing the issues. Jason also gave me several different options along with the probabilities for long term issues. I've lived here in Austin since 2008. I've seen Radiant's trucks, art work, and ads and always wondered if their service was as good as their marketing. I can honestly say that their service is even better than their marketing...and that takes into account their Oscar worthy film submission on HBO's Last Week Tonight with John Oliver.

If Radiant Plumbing and Air were a rock band, they’d be The Rolling Stones of home services—legends, still going strong, and somehow cooler than everyone else.

They came to my house and fixed a plumbing issue that had other companies scratching their heads like it was the final question on Jeopardy! I half expected them to roll in with a cape and theme music, but no—just prompt, professional, and ridiculously knowledgeable humans who actually solved the problem.

Also, they previously installed my new AC unit, and let me tell you, my house now feels like the inside of a fancy hotel in Iceland. Glorious.

Everyone I’ve dealt with—from the folks answering the phones to the techs doing the work—has been kind, skilled, and not once tried to sell me anything I didn’t need. (Looking at you, Chad from That Other Company who suggested I replace my whole house.)

Radiant, you have ruined all other service providers for me. I’ll never settle for less again. 10/10, would trust you with my pipes, ducts, and possibly my life.

Jason gave us amazing, fast, knowledgeable service today! Our old water heater died during the first cold snap and snow Texas has seen in a long while. I called Radiant because their radio ads are kind of cute, and actually had to hang up right before they answered because someone at my work needed my attention. Radiant called me back immediately because they wanted to double check on the number that had just called... That's amazing! The service provider woman on the phone quickly got us set up with an appointment and said someone would call the next morning to schedule a specific time. No kidding, they called promptly at 7am to say they'd have a service provider out to the house by 8am. WOW! Jason our service provider was friendly, VERY knowledgeable, personable, efficient, and helpful. Great guy, superior service. We would recommend Radiant and Jason McNutt to anyone! Thanks, Radiant!

The Radiant Team was very responsive from start to finish in all ways. I thought I had an under-the-siding pipe leakage problem with my outdoor hose faucet because I could see increased surface moisture on the siding surrounding and below when I pressed on it.
Hunter was able to come by in about an hour to check it out. He gave me the good news that it was not an internal leak, just that the 42 year old faucet was too close to the house, and was leaking and spraying back onto the house. He was fully prepared to fix it immediately. He kept working in spite of a sudden rain falling on him! He didn’t just replace the faucet, He did additional work to protect the siding in the future, adding a much needed phalange, and extra piece to extend the pipe a little further away from the siding. He did quality work in my opinion. Thank you.

I’m a big DIY’er so it was hard for me to come to the conclusion that I needed to call an AC company to come check out my home unit that was freezing over. I called Radiant because of their reputation and hilarious advertising and they sent out Shiloh VanHyll. He was AMAZING!!! Made me feel like I was part of the process. I asked if I could watch what he was diagnosing and he took the time to explain the process and shared with me some industry tribal knowledge for things to look out for. We concluded that it’s probably time to replace my 15yr old unit and he got me scheduled the next morning with Majed Al-Aseeri to discuss repair and replacement options. Majed was very professional and didn’t try to oversell me on something I didn’t need but made sure to show me all of my options so I could make a clear informed decision on next steps. We found the right replacement unit that was within my budget and he got me scheduled the next morning for install. Installation day, Arturo Vences arrived on time, prepared and he and his partner got right to work. I’m EXTREMELY happy with the way Radiant treated me and you can tell that they Respect Customer Service, Honoring the Customers Time and Doing the Right Thing for their Customers.

Wow, absolutely incredible service! We worked with Byron and Cory, both very knowledgeable, kind, and transparent about costs and options. They both asked us several times if we had any questions and made it clear that their main goal was our comfort. Byron was respectful of our space and walked us through everything he found during the inspection. Once we decided to replace our unit, Cory visited us the next day to discuss the purchase and fine-tuned options to fit exactly what we needed. The install of our new unit was scheduled within only a few days of our first call!

Radiant has earned our loyalty and we will never work with any other HVAC/Plumbing company ❤️

Edit 10/6/22 - Radiant is still incredible! They came out same day to look at our water heater, gave us several options and helped us decide what would be best for our situation. Our technician, Brenden, was AWESOME! He was very understanding of our nervous dog, and was very accommodating & helpful. He made sure we had the best deal and took the time to explain what was happening and kept us informed every step of the way.

11/10!

We’ve used Radiant’s services a couple times. Once to install a new system and replace our ducting. They provided great customer service then and we have been happy with the HVAC system they recommended to us. Today we had a service call and from start to finish they nailed it. I called at 7am saying our AC was out, they immediately put us in an open service call and communicated with me through the day, giving me plenty of time to leave work to meet the tech. The service tech Jonathan was excellent. He was courteous and knowledgeable, and was thoughtful as he walked me through what he was doing. I appreciate that he took the time to educate me about the system. All this while being efficient and aware of my time constraints. We were back up and running in under an hour and I was back at work. We really appreciate a good business —it is always worth paying for experience, expertise and real service.

I can’t say enough good things about Radiant Plumbing and Air Conditioning - way better than the other phoney companies, who tried to scam me! I called Radiant Plumbing & AC for an emergency hot water issue, and they quoted a fair $39 trip charge, fair. When Radiant’s technician got delayed by one day, they were so professional they waived the $39 entirely without even asking for it, no charge for the trip! The plumber, Juan, was an absolute gem— kind, skilled, and a true professional. He fixed my water heater problem in just 2.5 mins minutes and said, ‘This was a piece of cake, a very easy problem!’ Instead of focusing on payment, he sent me photos and a detailed diagnosis email first, making sure I understood everything. When I asked about paying, he was super chill and said, ‘Don’t worry, the payment link will arrive in 10 to 15 minutes,’ and left without any pressure, trusting me to handle it later. They charged only $149 the fix, I tell you their professionalism is worth every penny. Honest, efficient, and genuinely caring—Juan and Radiant Plumbing and Air Conditioning are true artists in their craft, miles ahead of Champion AC and Plumbing Company. Easily the best plumbing service I’ve ever used!

Radiant did routine maintenance on two AC units at my home. One was leaking condensation
Which happens every year or so. Routine maintenance usually solves the problem. This time it did not so I called Radiant because I thought perhaps the drain had not been cleared. I was assured this was included in maintenance and within a couple of hours a Radiant tech was at my home. Sami cleared the line and worked to get it draining, albeit draining very slowly. He explained that it drained slightly uphill which hindered drainage. I have lived here over thirty years and routine maintenance always resolved the problem before but it continued to leak condensation for a couple of days and then stopped. After trying to determine what was different this time I realized we had recently had the hardest rainfall I had ever seen in the over thirty years I have lived here and once it dried up the condensate could drain despite the system’s very poor design.
Radiant has done many different services here over the years. Tech’s have consistently been very knowledgeable and courteous. Customer service is excellent. I suspect that Radiant is believed to be more expensive because the Techs find everything wrong. This is good information to have even if I cannot afford to have all work recommended done. I am very satisfied. The cost for routine maintenance was less than I have paid in years

I had an exceptional experience with management and there is nothing like an unexpected delight. You cannot forget something that you didn't care for service wise but, an excellent manager can certainly reframe your perspective.

I sometimes forget just how difficult (and hot) it is and by the time a technician reaches their umpteenth customer in this Texas heat, I need to remember that a little more grace should be extended.

They may not catch everything and they may not get things correct everytime but I need to take into account ALL the technicians get things right vs what they do not. I am very appreciative of any manager that seeks to ensure that as a customer, I am very much satisfied and even follows up to ensure as much.

Rest assured if you don't think you have been taken care of, the management team at Radiant will make sure that you are absolutely made whole. You are in excellent hands with management (current management in San Antonio). I cannot be held responsible for any changes after May 2025. I am beyond impressed. I would give a 10 but believe everyone has room to continue growing.

Working with Radiant was an absolute pleasure from start to finish. Cory Sinclair made the sales process incredibly smooth—no pressure, just honest, detailed info that made it feel like I was talking to a friend. I trusted his opinion completely and would gladly do business with him again.
The install team showed up on time and impressed me with their honesty. Even though they could’ve just done the job as quoted, they pointed out that it might cause problems down the line. Instead, they contacted Cory, and together they came up with a more labor-intensive plan to give me a more efficient AC system—at no extra cost.
Cory even showed up at my door, unannounced (on a Saturday that he was supposed to be celebrating his birthday!), to walk me through the new plan personally. That kind of service is rare. The entire experience was stress-free, thorough, and backed by top-notch customer service. I’m officially a customer for life.
Huge thanks to Cory and the whole Radiant team!

Erik was great. Thank you for being prompt and professional.

Brian C. was great! He was very professional and very adept. I have an issue where my AC can’t keep up and get below 80 on these 100 degree days. My house was built in 1985 and has a patchwork HVAC system.

I appreciated how thorough he was in trying to diagnose the problem(s). It didn’t seem like he’s the type of person to put a bandaid on the problem, hand me a bill and go - as many do. He looked at the problem from several ways, making small fixes here and there while being transparent with me as to how he’s trying to solve the issues. That extra effort he took did not go unnoticed. Whenever you’re not a subject-matter expert in something, you really want to know you can trust someone to be just as honest as well as they are proficient. No one wants to feel taken advantage of because they don’t know any better. I do trust Brian, as he took the time to discuss the issues he saw in layman’s terms for me. Many customers know nothing about HVAC and don’t want to be sold on anything expensive without really understanding why. The way to earn repeat business as much about trust-building as it is doing good work.

I will be honest, I’m not thrilled at the actual price tag for fixing my older system, but at least I’m more knowledgeable about what’s wrong and therefore more receptive to their advice on how to fix it.

I hope to have continued good experiences with Radiant.

We only call Radiant when we need a plumber. It’s a relief knowing that when a plumbing emergency strikes, we have a company we can trust. Let’s face it—calling a plumber on a Sunday for a potential slab leak is not something anyone wants to deal with. It’s stressful, potentially expensive, and, as a homeowner, there’s always a fear of being taken advantage of.

From the moment I called Radiant today, I felt reassured. Yes, I was worried—it was a Sunday, and I had a leak. But knowing that Radiant has highly trained, honest plumbers made all the difference. David Farmer arrived within a couple of hours, quickly diagnosed the issue, and thoroughly walked me through everything. He not only repaired what could be fixed today but also explained my options for the work that will need to be done in the coming months. His expertise and transparency made an otherwise stressful situation much easier to navigate. He took his time, did everything that needed to be done and because of his thoroughness we found that it wasn’t a slab leak at all. There is a laundry list of things that do need to be done but because of David’s honesty, patience, and skill level we know that a slab leak isn’t on that list and I wasn’t told a costly repair I didn’t need was necessary.

We had Radiant install our AC last summer and had an equally great experience then. After that, we stopped getting second quotes altogether. Radiant may not always be the least expensive, but they are absolutely the most knowledgeable, patient with my many questions, and transparent about costs. There are never any surprises—no hidden fees, no scope creep.

I cannot recommend David Farmer and the entire Radiant team more highly. Their professionalism, skill, and honesty set them apart. Plus, they’ve even helped us find trusted tradespeople when additional work was needed. If you’re looking for a reliable plumbing and HVAC company, Radiant is it!

Ezekiel Charles was amazing. Radiant plumbing, y’all need to give him a huge raise. He is one humble, honest and God loving person who only recommend what truly customer needs rather than what he wants to sell. I called Radiant to get a “quote” for water softener but with his thorough inspection and research, he found out I needed a water heater replacement. He went above and beyond to take him time and presented several options - from adding water softeners to simple repairs. His hawk eyes and experience caught that roof replacement cause the vent to bent and causing Carlton monoxide to flow back and damaging the water heater. Remember, only one needed to be repaired or replaced. Since other machines almost 9 years old and coming to the age and his honest opinion on what to to my husband ended with two water heater replacement and adding flow tech. Also, his went above and beyond with getting extra discount by calling his manager and contacting finance person for best option just won my heart. He is his namesake and God fearing man who represent Jesus to his customers!! Radiant Plumbing, thank you for hiring him and now please hire more like him and Give him a big bonus!! I will be loyal to you and promote your company!

I recently experienced a terrifying plumbing emergency – a major clog that resulted in significant water damage to my master bathroom. Panic quickly set in, but a quick call to Radiant Plumbing and Air brought immediate relief.

From the moment I contacted them, I was impressed by their professionalism and urgency. They understood the gravity of the situation and dispatched a technician, Paul H., within the hour. Paul arrived promptly and immediately assessed the problem. He explained the situation clearly and provided me with several options to address the clog and the resulting damage.

Paul's expertise was evident throughout the entire process. He worked diligently and efficiently to clear the clog and minimize further damage. He was also incredibly patient and understanding, answering all my questions and addressing my concerns with a calm and reassuring demeanor.

Thanks to Paul and the entire team at Radiant Plumbing and Air, I was able to avoid further damage. Their prompt response, expert service, and exceptional customer service truly saved the day. I highly recommend Radiant Plumbing and Air to anyone in need of reliable and professional plumbing services.

This past Saturday, around 5:30, my wife discovered we had a bathroom leak that caused major damage in the bathroom, bedroom, and closet. We contact Radiant, as they advertised that they were 24/7, and we had Paul come out and take a look at the issue. He quickly found out that it was a broke backwater valve and removed it. He said that he would send over a specialist to make sure there was no other issues. Jedediah soon arrived and notice the backwater valve was broken as well. He then took a look at our bathroom, closet, and bedroom and notice where bubbling had began. He then recommended a restoration company to help us determine how bad the damage was. Both Paul and Jedediah, were quick, responsive, and thorough with their assessments and helped us solve an issue in a timely manner before it could get worse than it already was!
