About Radiant
Two Cities, One Standard, Since 1999
Radiant Plumbing & Air Conditioning has kept Austin and San Antonio homes running for more than 25 years, with licensed local crews, upfront pricing and a phone that gets answered at 2 a.m.
Our Story
A Local Company That Grew Up With Central Texas
Radiant Plumbing & Air Conditioning started in Austin in 1999, back when the city was a good deal smaller and a plumber could still find parking downtown. We have been working on Central Texas homes ever since, through the building booms, the 100-degree summers and the February 2021 freeze that turned a lot of people into overnight experts on pipe insulation.
Along the way we added heating and cooling, then drains and sewers, then indoor air quality, and, for the Austin area, licensed electrical service. In San Antonio, Schmidt Mechanical is now part of Radiant, which gave us a second home base and a crew that already knew the city. Today more than 10,000 homeowners have called us, and thousands have left a five-star review afterward.
The name has never changed, and neither has the idea behind it: tell people the truth about what is wrong, give them a price before the work starts, and stand behind the job. If you have seen our toilet or our air conditioner wandering around a neighborhood, that is us too. We take the work seriously. Ourselves, a little less so.

Honest Recommendations
If a repair makes more sense than a replacement, we say so. Our technicians are trained to explain your options, not to hit a sales quota.
People You Can Let In
Every technician is licensed, trained, background-checked and bonded. You should never have to wonder about the person working under your sink.
We Stand Behind It
The Home Comfort Guarantee is in writing. If the work is not right, we come back. If we cannot fix it, we offer a 10% inconvenience refund up to $1,000.

What Is Different About Calling Radiant
Plenty of companies are licensed and insured. Here is what is worth knowing beyond that.
- One Company for the Whole House Plumbing, drains, heating, cooling and indoor air quality in both cities, plus electrical in Austin. When a water heater problem turns out to be a gas or wiring problem, nobody has to be called back out.
- Actually Local, in Both Markets An office on Reinli Street in Austin and one on Wye Drive in San Antonio, each staffed by people who live in that city and know its houses, its clay soil and its hard water.
- Same Price, Any Hour We are available 24/7, and our upfront pricing does not change for weekends or holidays. A failure at midnight is not something you chose.
- A Guarantee With Terms You Can Read The Home Comfort Guarantee spells out the 72-hour quote, the technician standards, the satisfaction refund and the no-backup promise on drain work. Read it on the guarantee page.

Our 18 year old HVAC system finally gave out this past week, so we reached out to Radiant to see what could be done. They sent a tech out named Bryan the same day, and he did a great job looking over the entire HVAC system. He was friendly and helpful in explaining everything that he saw, and our options moving forward. We decided to replace the entire system, so we met with Jacob (same day thankfully) to find the best HVAC system for our needs. Jacob was friendly, professional, and did a great job explaining the different options on offer. Radiant was able to set-up next day install, which was much appreciated, because the temps were still going to be cold in the coming days.
The install team consisted of Carlos and Pablo, who were very courteous and professional, and were kind enough to answer any questions I had regarding the install. They did a great job installing our new HVAC system, and were tidy which is always appreciated! Before they left, they explained everything that had been done, and showed me photos of the work.
Our entire experience from start to finish was great. I appreciate that they send photos of who is coming to your home too. Friendly, kind, professional team members, and good work all the way around. Thanks Radiant!

This is the first time I’ve used radiant my neighbor recommended them…. I called them today and they set me up an appointment on the same day. I was totally shocked at that and the service call was only $39!!…. Highly recommend them Danielle showed up and he was a great guy and he put up with all my wishy-washiness and I had to hurry him because I was heading to church and he got caught in a lot of traffic getting here he even would’ve installed the part that broke but I Didn’t have the time tonight….. He was patient with me and just told me to call the office first thing in the morning and get a service call set up…. Thank you so much Radiant!!….
With another cold front coming in tomorrow now I just hope they can get me scheduled for a separate call tomorrow but I have a feeling they will. They are such a great company!!😊😊

I had Radiant Plumbing replace my tankless water heater, damaged in the Feb. 2021 snowmageddon storm with a new unit. The process was smooth and professional from start to finish. The plumber, James, was extremely knowledgeable and thoroughly explained my options to me. The cost and time to perform the installation were just as estimated. When he was done, James explained how to maintain the system, what service would be needed and how to perform it, and answered all of my engineering geek questions. It was a thoroughly positive experience. I have used several different plumbers in Austin over the past 15 yrs, but my search is over - I will not hesitate to call Radiant next time and would recommend them unreservedly.
8/9/23 Update: I have subsequently used Radiant for a toilet repair, faucet installation (Danny), and drain work (Ezekiel) and they have continued to impress with knowledgeable, friendly plumbers and quality work.
