Centeral air conditioner

Does the fan work to evaporate the moisture? ACs are pretty easy to diagbose. Is it dripping in the house?

Could probably replace the hose with bits from ur local hardware store.

the filter should be somewhere either on the end of the furnace or on the duct work itself.....this is assumeing you do not have a filter grill inside the house

It is a two ton system. and without doing a heat load Calculation and not knowing the heat load It would not be anything but a guess. But if everything is working properly and the system is clean and with good duct work, than it should be big enough for the size of your house.

It sounds like you have too much air conditioner vs. conditioned space. This would cause dripping and short run times. Air conditioners are designed not only to cool the house but to pull the moisture out, if it is too big and cools the area too fast the outside of the ducts will begin to collect condensation like the outside of a cold glass of water.

If this vent is connected to the return air duct line back to your furnace I would close it off. The only reason that I can see for having a vent to the outside is if you need more combustion air supply.Thank you.

The sail switch is in the cold air return it is wired in with the humidastat when your furnace goes on the air movement pushs the sail down inside the duct work that makes a contact the lets the 24volts to the humidastat. If the humidastat calls for moisture it turns on the humidifier but only when the blower on the furnace is on So in short it detects air movement

Yes, The air conditioner evaporator core inside the vehicle is very cold when the a/c is operating and moisture will condense on the outside of it, especially on a humid day. This moisture then trickles down the sides of the core and collects in the plastic housing beneath the core where it then escapes through the evaporator housing drain tube and drips on the ground beneath the passenger side of the chassis. The more humidity in the air the more moisture you will see dripping onto the ground. If the little drip hose should ever get plugged up this water then will overflow the housing and drip on the passenger side carpet so if you ever have that problem you'll know what the cause is.

if the closet the inside unit is in is vented to the house the filter should be inside the unit at the top or bottom.
