Radiant installed the Water Softener I had purchased. The price was a little steep, but the technician Gunner Brown made up for it. He was professional, efficient, and went above and beyond to help out.

Absolutely terrible experience.
I was told upfront about a $59 dispatch fee, which was fine. What wasn’t disclosed was an additional $120 “diagnostic” charge just for the technician to use basic tools. That only came up AFTER the visit, which is extremely misleading.
The technician they sent couldn’t even do the job I requested. I asked about installing a whole-home dehumidifier and adding a return duct, and he couldn’t provide a quote. He spent most of the time calling his sales manager and then told me someone else would have to come out on another visit just to quote it. So now I’m expected to pay multiple service fees just to get pricing? That’s ridiculous.
They did run something through their system and showed me on a phone that my setup is “undersized,” but there was no real explanation, no measurements provided, and no actual solution—just a vague statement and a push for another visit.
To make it worse, they didn’t even tune or service the system during the visit. So I paid extra fees for absolutely no value.
Hidden charges, unqualified techs, and zero deliverables. Complete waste of time and money. Would not recommend.
