Tierney Electrical Contracting LLC

Mark was fantastic, he was able to troubleshoot and isolate the problem quickly. Because of a recent large renovation project there were issues with our new NEST thermostat working with the new zone and air handler, that our builder cloud not resolve. Our contractor's subs made several attempts and could not fix the problem. Mark came in today and got right down to business. Really knows his stuff. He found the problem within in 1/2 an hour. He was very thorough and check everything and did not leave until he was convinced he had fix the problem. Not that I hope to have to call him again, but if I need any electrical work in the future, he's my first call.

Mark and crew are professional and knowledgable as well as easy to work with. They removed old fixtures and installed recessed LED fixtures with separate dimmer controls; wired in all new electrical outlets where I wanted them; sourced and installed a self-powered phone jack so no wires are showing.

Great. Mark is a little busy and has trouble scheduling...but he is fantastic once he gets there. He is really efficient and offers suggestions along the way. We only ran in to 1 issue in the dozen or so projects he has done for us and it was related to an item his assistant worked on. Good quality, great guy, Mark is our go to electrician.

Excellent. We've had Mark and his crew do work before. Very organized, does things to code. Will point out what is not to code and advise and give options. Calls a day ahead and confirm the plan in detail so he has the right equipment and that they can do the job quickly without adding time to the job. He is not the cheapest electrician but we have been burned a few times with others so we now stick with him due to his professionalism.
