Despite a recent house cleaning, I was amazed how quickly dust and other particulates started appearing on my floors and furniture surfaces. After a quick call to Advanpro, I was given a good understanding of the available services and arranged for a next morning service call. Steve and Alvin arrived in the prescribed arrival window, and within 90 minutes had completed the vacuum / brushing of 27 air vents, a HE furnace bypass and the associated duct work, along with a replacement of the furnace filter. They were courteous and went about their work in an efficient and effective manner - explaining what they were going to do and keeping me informed of their progress. They even shared with me why my children's bathroom was not receiving any airflow - it turns out my 5 y.o. may have stuffed an entire roll of toilet paper down the air vent. Now with the blockage removed, that room is receiving effective airflow.
Thanks again, guys! Excellent work!
