Jordan Valles was absolutely amazing, as a new homeowner experiencing my first plumbing issue, he walked us through the issue thoroughly, recommend and helped solve the issue quickly. Great experience over all, great communication before and after the appt. 10/10 for these guys

Radiant has a wonderful customer service department. Every time I called, someone responded and spoke very politely. Technician, Kevin, came on time, answered all our questions, and helped explain everything. He unclogged our primary drain and did it very quickly. Would definitely recommend Radiant Plumbing and Air Conditioning!

Brenda J.

We needed a plumber to come out asap as we developed a leak when trying to replace a bathroom faucet. He arrived with 2 hours and our faucet & pipes are as good as new! He was very nice & knew his expertise! We highly recommend!

Maygen R.

I had a wonderful experience with Radiant! I am a new homeowner of 1 year and recently heard my water heater making some noise. I was so pleased with how informative and professional the techs were. I had a great experience and the WH has been nice and quiet. Thank you Radiant!

Jonadav M.

Jason is the best in his class as a plumber!!!! I did the right thing of calling Radiant plumbing company because your customer care Dan was very receptive on my problems while Rey assured me that a plumber was on his way today and you sent me Jason who I believed is the very best definition of an excellent plumber! Thanks for all the help!

K. D.

Radiant immediately acted on our emergency situation, was thorough and EXTREMELY priced well. So grateful to have a new plumber. Jason is a 3rd generation plumber. He and Joey were an absolute JOY to have around to do the work!!!

Suzie K.

We called Radiant Monday morning when 2 faucets got reduced flow over the weekend. We were COMPLETELY happy with our new faucets. Jason & Joey were awesome, careful & very competent. They even adjusted our toilet floaters & quickly secured 2 loose faucet handles, just being helpful.

Denise V.

Called in for a clogged drain on a Sunday night, unfortunately a pretty powerful electrical storm came the same night and blew out the elements on my 1 year old water heater. Wayne and another gentlemen showed up and they were able to address both issues at the same time. He was able to call and get the parts ordered and fix the drain expeditiously! Thank you!

Simon L.

Every experience we have had with Radiant has always been pleasant, and our most recent service call was no exception. Jason and Joe did a great job, answered all our questions, and found the source of a bad leak we had really quickly. They were extremely professional and courteous, and we will definitely recommend Radiant to everyone we know based on the quality of the crew and the work they do.
