Week after week I find my mailbox stuffed with ads and coupons, most of which I ignore. But there’s one that always catches my eye: AIR DUCT CLEANING $45 -- Call today to get this amazing deal! 10% military and senior citizens discount Negative Pressure Air Duct Cleaning Unlimited Vents to a Single Furnace Just heresay, but here's what I’m told: - Appointments are 8 months out. - It’s nothing but a scam (once the gear is all unpacked in your house) to up-sell. - Demand the $45 advertized special? They do a 10-minute half-*ssed job, skipping most vents. If you insist, they just leave. So, has anyone in the Portland area used a local firm with a realistic schedule, and who doesn’t charge an arm and a leg (like my heating company) to do a decent job cleaning vents? Would appreciate any legit leads. Thanks in advance.
