Recent Review: I got a coupon out of Valpak for an $109 "Air Duct Cleaning" (huge font on their ad) in January. This is the exact ad: "Unlimited vents and returns: we open, brush, and vacuum the entire duct work under negative pressure." I had heard of air duct cleaning scams before, but I thought to myself "it says it right here on the ad, they're going to clean the 'entire duct work.' The gentlemen (2) arrived at my house at 1:30pm and were greeted by my wife. When I got home from work an hour later, they were all but finished. They immediately sat me down in the kitchen and started with a very shady sales scheme in which they said things like "for legal/liability reasons, we can't say 'the M word,' but you've definitely got it." He wanted to spend the next 1.5 to 2 hours cleaning the entire duct work to start, my blower fan motor, and my return, for a total of $680. My first thought was "wow, $680 for two hours of labor, even my attorney friends don't bill their clients $340/hour. So of course I quickly said "i'm sorry, but i was under the impression that the duct work and return had been cleaned?? Isn't that what the coupon said?" He responded that the coupon was for the vents only. I asked my wife to fetch the coupon and she was unable to find it (naturally, we found it about 10 mins after they left). I was a bit confused to say the least, but let him continue. He also recommended installing a UV light system to 'zap' all of "the M word" before it enters the system, for a mere $600 (i later found the exact model on ebay for $140 delivered, and apparently they take 15 minutes to install). Lastly, he said we could have all of the ductwork replaced instead for $1600, which he assured me was the lowest price in town. As evidence, he pulled an old tattered estimate sheet from a competitor showing that this other company had quoted someone $2300 for duct replacement...this estimate was so old and beat up that it was literally falling apart. I told him that I needed some time to research all of these services, discuss them with my friends, etc., and he promptly said "that's fine, I understand, how 'bout you put down a $50 deposit now for any service, and you can apply that when we come back and do the work." That was probably the biggest red flag, and I very politely thanked them for their work and told them to call me in a week. I've since screened all their calls, and this month's valpak came in the mail recently, with their same coupon claiming to clean "the entire duct work." I'm usually good about sniffing these things out, and had i found the coupon while they were here, we would have had some words. So the whole ordeal was a little embarrassing. The guy was a very well spoken immigrant and I can see how his charm would work on a senior citizen or woman, but luckily I returned home before they had time to intimidate my wife without me. While I wouldn't classify this as an outright scam, it was at best a classic 'bait and switch,' and we've since hired a professional certified mold inspector who spent 3 hours at our house and found absolutely no mold whatsoever. Google "air duct cleaning scams" and they all follow the same general blueprint that was used on me. Buyer beware!
