I thought I took good care of my Accentra with weekly cleanings, but it wasn't until I experienced the "left side blowing cold" problem recently that I realized I'd been neglecting part of the snow. When I finally got it pulled out and started poking around with a headlamp, I saw the blockage at the back of the distribution channels (if that's what they're called, behind the dist blower) that I realized I hadn't gotten back there. I ended up bending a coat hanger and poking around with that to get it clear, but I'd like to get the correct brush for the job. Is there one that goes in through the vents at the front/top of the unit? Or is it advised to pull off the heat exchangers to go at it that way? Is there a brush you all swear by?
