An HVAC technician shows how to clear clogged drain lines using a compact vacuum setup and a nitrogen-powered sludge sucker. He navigates tight elbows, checks both upstairs and downstairs drains, and explains why nitrogen gives stronger suction than a standard vacuum pump.
Now sometimes they don't make it easy on us. Like in this case they have this with the elbow turning down. You can't put your vacuum, you can't put stuff on it. So I keep my little setup with me. That way I can get a little bit of access so I can pull the vacuum on it. Now in the summer, it is a case of when I checked the unit on the upstairs, I had noticed that there was a lot of sludge and, you know, dirt and stuff collecting in the drain. I typically would have used what we call is a sludge sucker. So this device that I use and I would hook it up to my nitrogen tank and this creates a much stronger suction to clear the drain than a vacuum pump would pretty much. But in this case, I know I just inspect the drain line upstairs. It was pretty clear. And I know she's not using any AC right now.
