I based my selection of cyclone air systems from my experiences of selecting services from Yelp; based on reviews and usually interviewing 3-5 different companies and to ask questions of methods, etc. Also listening to their explanations. I have done my share of thorough Yelp! reviews, which others have relied on, and also resulted in providing/adding their personal opinion on Yelp. I think the majority of reviews on businesses speak for themselves. I notice the very few disgruntled reviewers have never Yelp!-reviewed contractors or home service companies before. Or understand that distance between the wall vent opening to the outdoor hood or flue differs in homes. Some are short distances. Others can be a longer run for ducting to be cleaned out. Including bends or to another home level. A reason cleaning times can vary. I did call 5 different companies for methods used and estimates/quotes. I live in a small 23 y.o. homeowners association (HOA) in San Francisco, comprised of 8 homes. I usually do the research, interviewing and selection of a company for providing their specialized services. Contractors in their area of expertise or reputable general contractors. I called all 5 vent cleaning companies on my list, including the one our HOA has used several times. But decided, from experience and hearing of methods used by the other companies, to go with cyclone air systems. I spoke with Mario, the co-owner, and he explained his company's method for clothes dryer vent cleaning. They use 2-types of brushes: a harder brush to release build-up at 90 degree bends; and a softer brush as a finishing clean. They start from inside of a home. If they are not satisfied, they also go to the roof and brush clean/vacuum the vent ducting. Trying to sync schedules with residents at home, at the same time, was the most difficult. But Mario understood from experience with HOA's. They do work weekends, the same time many customers request their service, because it's the only availability for working folks. So customers should understand to schedule weekend requests further in advance than weekdays. Mario and co-owner, Jose, came out. And Jose's bilingual skills came in handy for one home. What they noticed about all 8 homes, was that the vent tubing (sleeve) within the walls are all flex type and soft. Not rigid galvanized-type. So they preferred, in our HOA case, to use the soft brush to clean those out. A hard brush could tear the soft flex tubing (sleeve and ducting) within the wall. He said any damage to the flex tubing inside the walls could result in opening the walls to repair or replace. Something no homeowner would want to go through or the associated expense. Mario worked from the inside of homes, with the dryers turned on, monitoring the accumulation of lint and total clean out, during the process. And, at the same time, Jose on the roof end with the soft brush. They communicated to one another, sometimes by cell/mobile device, whether or not Jose had to continue or verify all was cleaned out. They had to take the caps off the roof flues to do that for the lint to escape. Lots of lint came out. Mine was the worst. Then afterward, re-anchored the caps. Never done by the previous vent cleaner. Nor those options offered. Mario and Jose were very attentive to avoid problems. Mario noticed one home's clothes dryer wall vent opening/mouth was missing the wall collar. The flex duct run from the dryer to the wall was just taped and loose. Mario tightly secured the connection and recommended that the owner have a proper collar at the opening installed. Mario and Jose were friendly, knowledgeable, thorough and professional. And they gave a group discount for our 8 homes. Which resulted in a 34% savings off the individual price normally charged per home. Slightly higher than the original vent cleaning company we used; only by about $18 total difference for all 8 homes. So not much more and a better thorough and attentive job. I highly recommend
