Recommended Customer Reviews

Extremely disappointed after spending $20k on a AC unit 2 months ago which doesn't work for the second time. You contact them, they say they'll come in the afternoon but don't show up, i guess it's the weekend now leaving us until maybe monday .....with no AC. Thank you ! and i'm sure you don't care.......

I called Radiant in an emergency and Louie came out. He was responsive, honest, customer service oriented, and fast. The underlying problem was attributable to a portion of the City's line that got backed up. Instead of just fixing the issue himself and charging me (I wouldn't have known either way based on the location of the pipe and the related issue), he suggested that I call the City first. In the interim, Louie fixed some damage that occurred as a result of the back up and waited until the City arrived. The City confirmed that it was their portion of the pipe causing the trouble and they repaired it themselves that same evening. Louie didn't leave until the City completed their review and diagnosis and confirmed that the City would pick up the bill and do the work. Radiant called the following day to make sure everything with the City had gone well and that I didn't have any additional issues. I was very pleasantly surprised with my entire Radiant experience. Call Radiant and ask for Louie!

I have used Radiant for all my HVAC and Plumbing needs since 2012. First in a home I owned and now as a renter (called them in an emergency, and now my landlord is sold on them). They are responsive, honest, customer service oriented, and fast. They are not the least expensive if that's your only concern. However, you get what you pay for. With Radiant, you get follow up, you get things fixed the first time, and, you get, for example, someone out at your house at 10 PM when your AC breaks in August and your house is 95 degrees and no one can sleep.
Just recently, I had Chris, a plumber out at the rental house working on an issue with the toilets, and the scheduler, Morgan was awesome. She worked with me around an appointment I had to get him here in the morning. My landlord is not an easy sell. The fact that she, when I tell her there is a plumbing issue, now says, "Oh, well, let's just use Radiant again," is akin to SEVEN stars. She usually goes for the least expensive first, no matter what. She gets it. Radiant gets the job done right the first time with guarantees and cutomer service. I cannot say enough about the quality of work and customer service orientation of this company (also, booties in the house, clean up after themselves, I could go on, and on).

I should have read the Yelp reviews first. For a 50 gallon Rheem replacement heater with an expansion tank they quoted $2812.00. Tried another company and they came out right away and installed same equipment for $1410.00.

They charged $30 dollars to come out to location when he arrived he said it would cost $350 to diagnose problem with my on demand hot water heater. After complaining about the cost to review he reduced to $175. His results after review bad unit cost $4000 to replace. I quick checked amazon for same unit $1,200. Paid review fee and sent him on his way. Be careful!

Joe Lodzinski was my tech and he was great. Friendly and respectful. Didn't mind answering a million questions. There are quite a few things that can go wrong with HVAC and Joe took his time to explain and show me everything that was important. Radiant even did an on the spot electrical repair for less than the electrician quoted me.
Great experience with an Austin company. Will use again and highly recommend.

Response, Respect, and Really good work from Radiant. We had a water heater break flood our house, after calling several plumbing companies- within 2 hrs, Radiant was first to come out. The tech was David and the delivery driver was Sergio, both showed a high level of customer service and they gladly did their work. David answered my multitude of questions and then took his time replacing the water heater- $2500, seemed expensive but you get quality product (Rheem), 2 yr warranty, and Radiant takes care of the city permit and inspection as part of package.
Be careful that lower prices at others may not include the city permit/inspect.
Overall, very happy that David got our lives back to normal. More affordable pricing would get a 5th star, otherwise superior service.

The used car salesman of Plumbing in Austin. Received a quote for over $2,700 with me providing parts, found another plumber who did for $750 parts included. Scares me to think how many other people they have scammed like this. BUYER BEWARE!

Our furnace went out on a Tuesday morning. That evening, we realized the pilot light was out and the ignition button was no longer functional, so I went online to check out Radiant. I filled out an online request for information and kept poking around the website. While I was still looking, they called me, asked some questions, and scheduled techs for service the next morning.
The next day, 2 gentlemen came out (Phil and Joe - hi guys!) and they were absolutely professional, friendly, and fun to talk to. From there, Woody (hi!) came out and continued the trend. We determined we needed a new system and he helped us figure out the appropriate size and price level unit for our situation. Eddie (yo!) came later to start the removal process of our existing unit, with the team of Mike & Rene (hey hey!) to come the next day to complete the install.
Mike and Rene came the next morning, right on time. They told us what to expect throughout the day, made a heck of a mess, cleaned it up impressively, and reconnected our thermostat. There was something wrong with the connection between the thermostat and the furnace, so since Eddie was back, he took over the troubleshooting. Mike & Rene left (you guys are awesome!) and Eddie spent the next 2 hours troubleshooting the thermostat with the manufacturer support folks on the phone. He ran up and down the stairs, disconnected and reconnected wires, checked things outside, and ended up reinstalling our super old thermostat to get us heat while we wait for a replacement thermostat from the manufacturer.
None of these guys had to be this kind. Yes, in a professional setting, it should be that way, but we all know it's not that common. These guys were all friendly and fun to talk to on top of doing their job. They showed patience with the weirdness that was happening with the thermostat and all the questions we asked.
We are happy with the service we've received from Radiant. Thanks, everyone!

I thought I'd be able to use this company for a tune up for my heating unit, and to be our go to for plumbing needs. We just bought our home and wanted to be proactive in keeping our home in order. Well after the so called 'tune up' my heat was blowing cold. It was fine before. When I called to have a tech return, they wanted to charge me $159, even though I'd just paid for tune up that morning!
After troubleshooting online, I solved the issue myself.
Freezing at 4am definitely turned me into a HVAC tech. I have called continuously to speak with a supervisor, but I'm getting nothing. They had the tech call me back saying that it's basically my problem to deal with. I have asked numerous people, for literature or details of the service I paid for. No one can even tell what a tune up entails, nor will tell me what service they did to my unit. Well the tech said a tune up is really a check up, not a service. I call BS!!!
So I'm basically out of my hard earned money, and now I need even more servicing. No apology, no desire to make it right. I'm disappointed.
