Harlan Johnson maintains & services our commercial HVAC units. Very impressed with how this company handled a recent service situation. When a follow-up issue came up, the service manager took the time to review it and resolved everything quickly and fairly. That kind of accountability and customer care is rare these days. I truly appreciate a company that stands behind their work.
This review is not really about NTX but about the person they sent out from a different company. His name was Miguel and he was excellent. Very knowledgeable, didn't rush thru his evaluation of our problems even though it was very late in the afternoon/evening! He works for Harlin Johnson Plumbing and I would definitely use him again fingers crossed we don't need one anytime soon!

Best service I’ve received for any type of home repair in years. Jennifer at dispatch was so caring and efficient. Our technician, Jesus, was top notch an went above and beyond to help. He was also patient with our toddler and dog. I highly recommend.
The HJ tech Charles was on-time, friendly, and professional on the HVAC maintenance visit. He patiently answered my questions, and was efficient and clean in his work. I would definitely use him and HJ again in the future.
Jose rescued my house. I had 50 year old cast iron pipes that had to be replaced, plus other plumbing issues. Jose was so patient with me as I had lots of questions, and he explained things clearly. He was professional, yet always sensitive to my anxieties that come with undertaking such a huge disruptive project. It was clearly evident that he took immense pride in doing his job well. It was a comfort knowing he would do the right thing, the right way. I found him to be a man of integrity-- which you don't always find as we all know.
