"Update 10/07 — I had an electrical issue with a washer/dryer (due to manufacturer error), and texted Tripped for help at 1pm. They had someone drive out immediately (my home is in a VERY remote location), and Marqus arrived by 3pm. The issue was fixed by 3:45pm. This company has EXCELLENT service, and I could not recommend them enough!"
