I want to thank 313 Local Duct Cleaning Duct Cleaning and Duct Cleaning for their exceptional service. Specifically I want commend Uri for doing a great job of cleaning my ACs, duct and fireplaces, but more importantly for his work ethic in chasing down an intermittent sound when he restarted the main AC. That intermittent noise was the reason for my call to 313 Local Duct Cleaning. What Uri found was a wedge of 2 x 4” that had somehow fallen into the ACs heat exchanger. The wood shows signs of small flames and some notable charring. My home smells cleaner, there’s no noise coming from my AC and I slept with peace of mind.
