My outside HVAC unit has a frozen line coming into the house, what do I do?

Answer 1

Check filter if it is clean make sure nothing blocking return air. If ice start to form on outside and works in toward the coil then it is an air flow problem. Other than that better call a repairman. Cheaper in the long run.

Answer 2

there are a few things that will cause an a/c unit to freeze up the number one cause is, the unit is low on freon ,you will have to have the charge checked , it could also be that the evaporator motor (inside the furnace) is not running, it could be a dirty filter ,also the a- coil could be dirty. turn off the unit for at least 8 hours so the a- coil can thaw out , turn it back on and see if you have good air flow from the vents, if so that eliminates the filter and a- coil and evaporator motor ,have the charge checked.

Answer 3

as was stated make sure there are no restriction on the air flow at the return dirty filter ,coil froze up, make sure the blower is working and blowing out air, make sure the unit outside doesn't have any restrictions dirty coil fan covered up with debris, make sure the outside fan is coming on if these suggestion are checked out then it maybe time to call a repair person.

Filter may be clogged.
Evaporator may be dirty.
System may be low on refrigerant.

Turn it off, let it thaw. You should get a professional to look at it.

Answer 5

You have a coolant leak. Call the AC man and have him check out to find the coolant leak, repair it and then put in more coolant.
