Frequently Asked Questions
What happened to Schmidt Mechanical?
Schmidt Mechanical in San Antonio is now part of Radiant Plumbing & Air Conditioning. Homeowners who used Schmidt for heating, air conditioning and plumbing are now served by Radiant’s San Antonio team, which works out of 10927 Wye Dr., Suite 102 and holds its own San Antonio licenses: Master Plumbing M-45619 and HVAC TACLB138286E. Radiant has served Austin and San Antonio since 1999, and the same standards apply here: upfront pricing, no surprise fees, and the Home Comfort Guarantee on every job.
I was a Schmidt customer. How do I book service with Radiant?
The same way any Radiant customer does: call or schedule online, any hour of any day. Mention that you were a Schmidt Mechanical customer when you book so our team has the context. A licensed, background-checked technician will come out, diagnose the problem, and give you an accurate quote before any work begins. That quote is honored for 72 hours, and there are no surprise fees, even on nights, weekends and holidays.
Is there a maintenance plan for San Antonio homes?
Yes. Care Club is $9.99 a month and includes two HVAC tune-ups a year on an enrolled system, an annual whole-home plumbing safety inspection, 5% off repairs, priority service, member-exclusive deals and no dispatch fees, ever. Emergency service is available 24/7 at standard rates with no after-hours trip fees. In a city where air conditioners run seven months a year and hard water works on every water heater, two tune-ups and a plumbing inspection each year are the cheapest insurance you can buy for the house.
What does Radiant’s guarantee cover?
The Home Comfort Guarantee covers five things. You get an accurate quote before work begins, honored for 72 hours, with no hidden fees. Every technician is trained, background-checked and bonded. If we cannot resolve your issue, you receive a 10% inconvenience refund, up to $1,000. HVAC installations over $3,000 are quality-reviewed by a manager. And after a drain clearing or sewer replacement, if drainage backs up or slows, we come check it at no charge and make it right if it is related to our work.

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.
