"We recently completed the build out of our new 3200 square foot office and had the pleasure of working with Jimmy and his crew from JT Low Voltage & Electrical.

The phone and data installation went as planned and exceeded our expectations. The data racks look very professional and make maintenance easy. Our sound system with ceiling speakers is very impressive.

Most importantly, Jimmy’s team was professional, courteous, and completed everything as promised. We highly recommend them!"

"We recently completed a 13,000 square foot renovation for our new office space. JT Low Voltage & Electrical had the responsibility for the computer and phone cabling as well as the installation of lighting and all the electrical work. The results were fantastic. We really appreciated all the work they did to make this project a success.

JT Low Voltage completely rewired all the phone and data connections in the space, this was done on time and exactly as we specified. The electrical work will make it much easier to manage our operation and expand our data center as needed.

In addition, we are very pleased with the way the telephone and data racks are laid out and how easy it is to trace connections and make changes as needed without requiring a lot of time or effort.

I highly recommend JT Low Voltage for a quality job, the extra effort they put in made our project a tremendous success."

"Knowledgeable, Reliability and Professionalism.  These are the qualities that we expect to get from a business when you call on them to help with work you need to have done.  I can honestly say that Jimmy and JT Low Voltage delivers all those qualities.  The work he has done for us at both Georgetown Chrysler Jeep Dodge and Georgetown Subaru has been exceptional.  His knowledge of accommodating us in adding, re-directing, reprogramming and installing phone lines is always on the mark!  After he completes the work, he double checks everything that we requested is working properly and to our satisfaction.  He also takes time to explain any programming that is needed to be done on our part.  He is a true Professional in his business."
