Horrible, horrible company.  Like others, I was scammed.  I bought a Groupon and when the service agents arrived I told them that I needed the ducts cleaned because I have a very sick son who suffers from allergy and asthma, among other issues.  I never should have done this because they played on my weakness (and stupidity!).  We are two smart business professionals and we fell for this, I can't imagine how many elderly or less capable people they've taken.\n\nEssentially I believe this company runs a scam cleaning/air duct servicing business by performing unnecessary/unneeded services at 5 times the original quoted rate. I hired this company to clean my air ducts for $49 per condenser. When they arrived they informed me that they needed to clean the units as well, to the tune of $255 a piece. I felt like I had no choice--in order to get the service I paid for I had to pay an additional $600+! To convince me that this service was needed they showed me pictures that were supposedly taken of my units just minutes prior. I agreed and they were in and out in less than an hour. I checked online after the service and see that this company is notorious for this scam. Every single review I could find mentions this claim that in order to clean the ducts the homeowner must pay to have the units clean. The scam is always the same--show the homeowner pictures of units with mold and proceed to tell them cleaning is required in order for duct servicing. \n\nIn addition to checking online I contacted my contractor who remodeled my entire home from top to bottom and completed the project the week before this company cleaned the ducts. He said that the pictures they showed me of my air duct units could not have been mine as mine were cleaned off well by his workers during the remodel FOR FREE and there were absolutely no signs of mold. Not only that, but he informed me that these units get dirty, it's just a fact.  They are meant to function that way.  It appears they use pictures and descriptions of other units to scare you into cleaning the units. Mold, mice droppings, dirt--you name it, they claim you have it.  Not only did they charge me $600 based on what appear to be false representations, but they also failed to perform the service they were originally paid to do--clean the ducts. My contractor checked the ducts in my master bathroom the day after Custom Air Specialists came out and he said they were never cleaned as claimed.  My contractor has become extremely familiar with my home over the past few months and has nothing to gain, so he has no reason to be anything less than straightforward. \n\nThis company should be put out of business, but apparently they go by several names so a closure likely wouldn't affect them. \n\nBuyer BEWARE!  Don't be as dumb as I am.  When this company tries to upsell you and claim your units are in horrible condition and won't function properly, call a more reputable business.
