hey bud i'm new to this fourm to.I use to do some hvac work. now the drains ,are they not 1 a little higher than the other?if this is an upflow system the coil is on the top of the furnace.it wont drip when its running because the coil may be dirty and the air flow is preventing it.go to a pluming supply store and get a degreeser .if there is no access door to the coil go to a heating supply store and get 1 to fit .check to see if the coil is level. spray the coil with the degreeser ,if u can use a brush to work it.wait 5 min then hose off useing a garden sprayer.If u can , try to lower the speed of your furnace ,though it was probably turned up when it froze before,and now the cfm is to high blowing the condensation up the plenum and when the system shuts off the condensation comes back down the sides.if its a downflow furnace the you most likely freezing up ,or the cfm is to great and the negative preasure is preventing the drainning,( if you don't have a p-trap on the drain) .if all this fails the system is most likely over charged and you would need an a/c guy to check this .and make sure he checks with guages ,ask for a trade ticket from the guy that comes out .these companies often send apprentices out and they do something like speed up the fan .the other problem could be that the duct size has not been sized for a/c .So if the air flow has to be at the cfm it is ,you could seal around the coil and the plenum and up high on the plenum ,above the coil ,cut a 4-5" hole and put a grill on it ,this will relieve some presure on the system and the moisture should drip while its running.your vents should not lift the girls skirts up ,thats to much air.now the whole problem could have started by having a really dirty filter,so it froze up ,you changed the filter and had someone look at it??? the quick fix was to speed up the fan ,but is the filter is kept kleen the problem would likely stay away???I use a washable filter from home D ,replace the rivet with a screw and wash every 3 months ,i have had this filter for 4years
Really I could go on for ever.. make sure the drain has a P-trap on it 1"down and 1" up is a 1"water columb you should use a 3 or 4 ,and prime it (fill with water)and plug that other hole air and water will allways take the path of least resistance.....hope this helps ,its been a few years since ive been in the bizzzz
