Pumping dryer air outside

We have an unusually long clothes-dryer exhaust duct. It travels along the floor, makes three elbow turns to go up about 8 ft., then a horizontal run to the outside. It’s always been a pain to keep the lint from collecting in the ductwork and it doesn’t take a rocket scientist to figure out that the exhaust efficiency is pathetic.
   Many months ago, I acquired the No-Clog Dryer Duct Booster, manufactured by Tjernlund Products Inc., White Bear Lake, MN, one of our regular advertisers. At the time, I put it in the laundry room to be installed “when I get some free time.” Every time I had to move it, I thought to myself, “I really need to install that thing and see if it works as advertised.” It sure wasn’t going to boost any air sitting in its box.
   About three weeks ago, I discovered that a contractor we hired for some remodeling had knocked the dryer duct off of the back of the dryer. Every time my wife dried clothes, most of the exhaust was getting pumped into the laundry room. That was the tipping point.
   The time had come to install the booster. I dismantled and cleaned the ductwork and, before reassembling, cracked open the Duct Booster box, braced for a some-assembly-required, duct-tape-wrapping, new-wiring, wood-cutting, 10-trips-to-Home-Depot, all-day project. I’m more than happy to report that none of that materialized.
   I had to make one trip to Home Depot and had the Booster installed and all ductwork back in place in about an hour. I plugged the Booster in and it did its calibration, as described in the instructions. Yes, I’m one of those who actually reads the instructions.
   The real test was the first load of laundry. That happened the next day. My wife and I were at full attention when she punched the start button on the dryer. The dryer started and a brief moment later the Booster fired up. I expected to hear the screaming of a small jet engine. Instead, whatever sound the Booster made/makes, is drowned out by the dryer.
   Though quiet, it moves some SERIOUS AIR! I went outside and immediately was concerned that lint would soon be plastered on the neighbor’s house. Warm, moist dryer air was howling out of that vent. Back in the laundry room, the usual buildup of heat during a drying session didn’t happen. Bad in the Illinois winters, but great in the summer when drying clothes was always accompanied by extra AC operation. According to my wife, clothes now dry better and much faster.
   My only regret? That I didn’t install the Booster many months ago. I don’t make it a habit of endorsing products (it’s an integrity thing), but there have to be many commercial situations that involve long dryer-exhaust runs. If you have one, put the Booster on your upgrade list, and no, I don’t offer installation services.—Gary L. Parr
