From the initial quote, to negotiating the price, to doing the work, and cleaning up, these guys were complete pros. We had 3 other quotes, and when AC came in with the highest, they were willing to come down in price when I made some easy changes to the scope of work. We selected them because they instilled the most confidence in their work, and appeared to be the most dedicated to getting things right. They estimated that it would take 4-5 days to finish the job, but were done in 3-1/2 days, and left the house cleaner than it was when they started. They made very few access holes, none of which were bigger than they needed to be, and all the wiring was extremely neat and tidy, even when it was buried inside a wall (we did a bathroom reno after they left). The guys were courteous, professional, and punctual. All of the knob and tube that was accessible (and some that wasn't) was completely removed, and they provided a certificate upon completion for the insurance company. The job was completed on budget, exactly how we wanted it, and ahead of schedule.
