If indoor blower is running it sounds like you are low on refrigerant. Have a qualified technician test system for you.

Make sure the indoor filters are clean. The outside unit will continue to run until the indoor reaches the temperature you have selected. Dirty filters can throw the temperature out. Its common for outdoor units to freeze up when on heating mode if the ambient air temperature is below 5 degrees Celcius.. The machine should however, defrost itself. There could be a problem with one of the pipe or air sensors on the outdoor unit.

How come my AC is on but the air coming out is not cold?


Check the refrigeration lines coming off the outside unit. One should be very cold and one relatively warm. If one is not very cold, then the compressor is not working. Usually you can hear it when it is running. The condenser fan in the outside unit should also be operating. If the compressor and fan are operating, but the refrigeration line is not cold, you probably have a refrigeration leak and have lost the coolant. You will need a service tech for the repair.

Ac unit isn't blowing


It sounds like your freezing up at the coil, which in turn, blocks airflow across coil and only a small amount of air comes out of the vents. This also explains the cold air coming from fan on the outside unit, since the system cannot absorb the heat from the inside of the house through the coil. Your air outside is usually blowing out warm to hot air because thats the heat it rejects out of your system. I would turn the thermostat to "OFF" and turn just the fan setting to "ON" instead of Auto, this thaws the system out faster. Give it time to fully thaw, make sure filters are clean, and check airflow. If airflow is back to normal, your problem is more than likely the charge of refrigerant. If you have to call a technician out, make sure the unit is not frozen at all before they get there, they would not be able to do anything with the system froze. Hope this helps and good luck!

Have ice build up on line leading into outside unit and ice buidup on inside units on my goodman air conditioner


Turn the system off on the thermostat and set the fan to "ON", this will thaw the ice faster if it hasn't already. When the system has completely thawed, which could take hours sometimes, depending on how bad it's frozen, then turn system back to "Cool" and start these checks>

1. Make sure filters are clean!
2. Make sure there is proper airflow through vents.
3. Make sure outside condenser fan motor is running.

If you have either no or minimal airflow, check the indoor blower to make sure it's working, if it is, the evaporator coil is dirty restricting the airflow. Be sure the system is thawed because the ice will also block the airflow!

If the condenser fan motor is not running, either the capacitor or the fan motor will need to be replaced.

If your filters are clean, you have good airflow through the house, and everything comes on like it should, it will most likely be the charge of refrigerant in the system is too low and you have a leak somewhere. If you have to have it charged, be sure the system is thawed before the technician gets there, he will not be able to do anything while it's froze.

Hope this helps and good luck!

My airconditioner is not cooling enough what could be the problem


Make sure the outdoor fan is running and check your air filters. Also make sure the indoor and outdoor coils are clean. If all is good then get the refrigerant charge checked.

My outside a/c condensing unit's fan runs, but inside vent air is not cold. compresser may not be running. inside vent air was cold last week. Janitrol ckj361ab is model # of outside unit.


Start the unit and go outside to see if the insulated pipe is sweating or cold, hot air should be discharging from top of outside unit. Since the breaker is not tripping, my best guess is the compressor is not operating. You might have to replace the capacitor.

If you can hear the compressor operating, then most
likely needs refrigerant

Not blowing cool air on my Ruud, 18 years old, outside unit.


If you have ice on the Line you are iced up. If coil is iced no air can get thru. Now First. Turn of ac and turn fan to on posotion. That will thaw unit. Let it run 45 minutes. That should do it. If the fan is not running you amy have a bad fan relay. One of the reason iced up unit is dirty evap, coil inside. Try to thaw it out first. You can clean the coil with a stool brush. Does not damage the coils. Good luck

Recharge air condition


Hello,

If you have solid ice build up on the "big" pipe (suction line) and very little air coming out of the vents, it's more an air flow problem; Inside fan not working, dirty coil inside (evaporator) or block filter. Open the cabinet inside and take a look there first.

This should be easy to fix; if the filter is dirty, replace it. should be done every month anyway.

If the coil is dirty, depending on access there's a 50/50 chance you can clean it you're self. If you can't you will have to call a technician who will pump all the freon in the outside unit, disconnect the coil, clean it & reinstall it, that should run you $200 to $300

You say there is a little air coming out so the fan is probably working, but if not, you will to find out why the fan is not running. That's electrical, could as easy as the thermostat is not turning the fan on to replacing the fan it self.

It is possible to have frost coming back if you are undercharge (low on freon) But the conditions have to be just right. A Journeyman mechanical carrying an EPA license working under A license contractor is the minimum you need to be able to buy freon since the 90's. that's legal of coarse.

To charge a system you also need a set of gauges and you need to know the working pressure of the system depending of the freon inside.

I think you only have a block filter or a dirty evaporator, possibly a collapse duct.

Good luck
