which is the superior method ? (or all they all alike for the most part).
(a). rotating brush / snake
(b). compressed air blow in one end, blow lint out other end.
(c). "viper" compressed jet snake device.
the current vent appears fine (no drying related complaints), and this is preventive maintenance only - but there's no telling when (or if) the prior homeowner ever cleaned it (home is about 10 yrs old).
the low ball price i got was for a compressed air flush of the vent (about $89)....other services quoted me about $200 using a brush/snake.
any opinions on one method over the other?
