What Your Austin Neighbors Are Raving About
Real Austin homeowners sharing their experiences with our Master Plumbers, HVAC technicians, and licensed Electricians.
"Emergency Sunday Morning Water Heater Replacement"
"I had a major hot water heater leak at my Airbnb on a Saturday night, and Radiant responded immediately. Marcel, a Master Plumber, arrived early Sunday morning. He diagnosed that my water heater needed replacement and recommended replacing both units since they were installed in tandem. He also corrected plumbing that had been installed incorrectly and brought everything up to code. Marcel presented several options without pressure. I chose two Marathon water heaters, and by that evening the entire installation was complete. Outstanding workmanship!"
"Severely Clogged Sink Fixed with 6-Month Warranty"
"Radiant serviced my home today and I couldn’t be more satisfied. They fixed a severely clogged double kitchen sink quickly and thoroughly. Garrett, the plumbing professional, was polite, knowledgeable, and took the time to explain exactly what was going on. Pricing was very fair, and I was given a 6-month warranty, which gave me even more confidence. They earned every bit of this 5-star review."
"Arrived in an Hour with Shoe Covers & Upfront Pricing"
"I called Radiant when my AC stopped cooling. They sent up-to-date notifications via text on when the technician would arrive with his name and photo! They sent Alex G. within an hour. When he arrived he put on shoe covers before coming into my house. He assessed the issue, explained the maintenance packages, and had my AC running again. Great company that doesn’t try to take advantage of women!"
"Knowledgeable Electrical Work for Backyard Project"
"Jason and Mike from Radiant Electrical provided an awesome service experience! They were professional, timely, and knowledgeable, understanding my vision for additional outlets I wanted in my backyard for current and future projects. Highly recommend Radiant Electrical!"
"Brand New AC with Easy Monthly Financing"
"A big thank you to Radiant AC! We have an old AC system over 10 years old that was going out on us. Tech Isaac came to inspect and was honest with us. Chase came the next day with a quote and we qualified for a financial payment plan. On Saturday Ryan and his coworker installed a brand new AC unit. The AC is cooling perfectly. Radiant is an amazing company!"
"Crane Roof Compressor Install with Zero Complaints"
"Ryan did an amazing job removing the old and installing a whole new HVAC system with the outside compressor on the 3rd floor roof, no less! AND did this with the crane driver to get the compressor on the roof. So many stairs, zero complaints! Ryan was a pleasure to work with."
"Honest Explanation for First-Time Homeowner"
"Jeff Hicks with Radiant was great. He came the same day I inquired about my shower water leak. As a first-time homeowner, he took the time to explain why I had a leak and what needed to be done without making me feel rushed. I highly recommend Jeff!"
"Used Both Plumbers & Electricians - Exceptional Quality"
"Exceptional work. I ended up needing plumbers and electricians, using Radiant for both. They took the time to inspect all areas, walk me through findings, and find options that worked for my budget. They couldn’t have been better!"
