If is not blowing ,the fan in the air handler is not working.It could be the capacitor or the fan motor itself, but if the fan works and you have ice in the air handler coil could be that the filter, is dirty, the coil is dirty or the unit is low in refrigerant.

Ptac blowing water in house


The water drain line is blocked. Check where it empties water outside the building as it is likely the end of the tube is blocked. Sometimes insects will build nest inside the end and block it or it might be a dirt build up. It is easy to fix.

Goldman capf3636b6. Fan outside is running blowing cold air to the outside.Inside is making a humming sound but not running.If I turn it off all of it stopsThere is some ice visible on the pipes


System needs to be thawed out, so turn it off before something else breaks, cause pipes are probably plugged and stopping any movement inside the system, Try using a blow dryer on high heat to help with the thaw out of the pipes with the ice build-up , then leave it off for a couple of hours and then try to turn it on again see if the unit in the house is running or blowing cold air again. Turn it on HIGH...!!!!

Amana ptac unit blows air, it feels kind of cool, but it's set at 65 and it's not reaching the desired temp... does it need 2 be recharged or are my lines possibly froze...???


If the unit is frozen you should be able to see ice at the indoor coil. If you pull the air filters and peer inside to the indoor coil there may be ice. Either way it needs service. If no ice and blowing cool not cold it could be the condenser coil is dirty. On the outside you can see the air leaving side of the condenser coil. The air entering side is the side that gets dirty and can only be seen by pulling the unit out of the wall. Its best to leave it in the wall and call a tech that has experience with ptacs.

In winter the outside unit sounds like a rubbing/ticking noise


Sounds like ice coming of the coil. That would explain the ticking. The rubbing could be ice buildup before the defrost cycle or it's building on the blades of the fan throwing it of balance a bit.

The air conditioner is pouring water on the floor!


Sounds like your water drain line is plugged. There should be a bundle of wires tubes and a drain hose that goes through the wall to the outside unit. The water drain hose should split off outside and drain on the ground. You should check that the drain hose is not plugged or kinked somewhere. The hose must also slope downwards from the inside unit to where it drains outside. You can check if the hose is plugged by blowing into it if you can reach the hose outside. You should be able to easily blow through the tubing back into the house. I have done this with this type of unit at night (determined to get it working), and was able to get it to start draining properly. Before I got it to start draining, I had the same waterfall that you are seeing. The unit had been off all winter. Hope this helps.

18 year old Janitrol Heat Pump freezing up.


i would get someone to check your refrigerant levels have you ever had the evaporator coil flushed and cleaned? proper refrigerant levels and proper airflow across coils are extremley important not to scare you but 18 yrs is a long time on a heat pump 9-12 years is the point where they really loose there efficiency going for a newer one would probably cut your operating cost in half if not more depending where you live there are a lot of people not familiar with heat pumps so i suggest finding a company that specializes in them to service your unit

Line to evaporator iced over


I am not exactly sure as to the type of unit you have. If it is a ductless split system (inside unit on the wall, never seen Lennox make one) you could be low on charge, the metering device to drop the refrigerant pressure is in the outdoor unit. If this is a whole house system, you may have a restriction in the outdoor section somewhere. If you look into the unit while it is running, try to find a filterdrier. It is a cylinder soldered into the small line. You can also see exactly where the ice starts, that is where your restriction is. Let me know what you find out.

Friedrich air conditioning - inside unit ice build up


Hi, Reduced air flow, low on freon or being continuously run during cooler weather such as at night. Some people turn their thermostat on 60 thinking that it will help get it cooler faster. They freeze up at night and don't get a chance to thaw during the day. It needs set no lower than 75 or so. The evaporator may be dirty. Don't know a lot about your particular unit but if the outside unit has the compressor and refrigerant lines running to it, The large refrigerant line should sweat all the way to the compressor if its fully charged. Please rate me if I have helped. Good luck kstfas
