00:09 the ninth question we get asked all the
00:11 time is how do you know my duct systems
00:13 leaking or is it leaking depending on
00:15 the variation of the the question it's
00:19 easy on some duct systems to do a visual
00:21 inspection and see that the duct system
00:24 is leaking if you have an old metal duct
00:26 system that has a yellow fiberglass on
00:28 it you'll see black rings every three to
00:31 five feet and where you see the elbows
00:33 where it turns those 90s and 45s you'll
00:35 see black rings around there most people
00:38 can easily walk into their garage if
00:39 that's where their furnace is located
00:41 and they'll see a bunch of black rings
00:42 around the ductwork in the garage
00:43 what's happening there again is the
00:45 venturi effect where there is a high
00:47 pressure leak to a low pressure area it
00:50 creates a suction so that fiberglass
00:52 acts like a filter so the filter in your
00:54 home that you're supposed to be changing
00:55 every sixty to ninety days is the
00:59 fiberglass and that fiberglass turns
01:00 black or at least and pulls that air
01:03 back in that's an easy way to visually
01:05 inspect that the duct system is leaking
01:07 on some of the newer duct systems it's
01:11 not as easy to see that sometimes you
01:13 got to peel back the connections and see
01:14 if it's properly affixed to the system
01:17 but we have guys that can come out and
01:19 actually pressure test the duct system
01:20 and tell you what your leak rate is and
01:23 what it should be so we can we do it
01:26 either way some people want the service
01:28 of the guy to come out with all his flow
01:30 hoods and it's pressure testing
01:31 equipment some people just need the
01:32 visual inspection and they can see that
01:34 it's leaking put a tissue up to it and
01:36 the tissue starts wiggling around it's
01:38 you know it's all about just inspecting
01:40 the duct system whether it be with
01:42 computer equipment or just a visual
01:44 inspection
