2 things could be happening. 1, inside unit needs filter changed and coil cleaned. 2, unit is low on freon. A/C tech should be able to check for both. You can check the a/c coil to clean it yourself but to check for low freon this will have to be done by a a/c tech due to the complexity of the system. the ice is caused by a series of things however, check the a/c filter and the coil located behind the filter. this coil should be free of any debris. if you have indoor pets sometimes the hair clogs the coil causing the freeze up.. To clean the coil you need to get a small weed killing sprayer.. At the a/c supply house you can purchase cleaning solution that is easy to use an safe for the enviroment also leaves your house smelling great. if the coil inside has been cleaned check to see if the coil outside is clean if not you can clean it with a water hose by spraying the coils out. MAKE SURE TO KILL THE POWER beforehand. Also spry the water onto the coils only and spray in the oppisite direction of air flow. Have system checked by a/c tech if you do not feel comfortable doing any of these suggestions

Why is central air blowing air but air is not cool


check and make sure outside unit is running. should have warm air coming out of condensor

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!

Outside central air conditioning unit not working, is there a reset button?


Hello my name is Heath it will be my pleasure to assist you. The first thing to check is the filter in the furnace or air handler. Also check the inside coil to be sure its not frozen up. Does the air coming out feel cold? It sounds like the unit could be low on charge which means it has a leak and should be leak checked repaired and properly charged. You would need refrigeration gauges to put on the system in order to properly check the refrigerant charge in the system. One other thing could be a dirty condenser coil. Turn the power off to the unit and use a garden hose with a strong nozzle and spray water through the whole coil to try and blow any dirt or debris through the condenser coil in the outside unit.

Central air conditioning system is blowing warm air.


many, many. Is the outside unit running? If it is, is the compressor running? Feel the refrigerant lines leaving the unit. Little one should be warm. Big one should be cold, probably sweating.

Why would cool air be blowing out of my central ac unit condensor that sits outside? The other unit I have next to it blows out warm air and responds well to thermostat changes. The unit blowing cool air...


It probably has a low refrigerant charge. The air coming out of the outside unit should be warmer than the outdoor temperature when in the cooling mode and if it's a heat pump it should be colder than the outdoor temperature in the the heating mode. Check the big line going to the unit, it should be somewhere around the 40 F range and the small line should be hot.

My heat unit will not blow hot air unless we go outside and hit a button on the back bottom of the unit. Once we do that it will blow hot air for that cycle. when it is time for it to come on it is cold...


If it does not have a furnace or heating elements for heating, then it is a heat pump, which is rare for a central AC system, but makes sense of the fact that it blows warm air when you reset the pressure switch, which may indicates freon pressure charge problem if your AC system has a reverse valve and uses freon to for heating (heat Pump).

Do you get heating when outside unit runs? if you do, check freon pressure levels and top up to required pressures. The button you depress is a pressure reset switch ... that is if your AC system is a heat pump ... which, as pointed above, it is not common for central ACs.

Central air unit only blows warm air , when set on cold


First check to see if your outside unit is working and you can here the compressor running. If the fan runs and the compressor does not you have a problem with the capacitor or wires burnt off terminals. If your not sure you know how to work on this please call a service tech ask for free estimate. If the unit compressor and fan runs you may be out of gas that meanns you have a leak. Either way you need a service tech. You can only go so far without the correct tools to work with. Russ

Central air/heat pump not putting out cold air


I have some things for you to check. If you look at the outside unit the lines going into the house. Are they frozen? Have you had any yard work done, the reason I ask is they could have accidentally cut or pulled out the thermostat wires to the ac unit. Also, inside check for the same thing, frozen lines. Also, you may want to check the drain coming from the inside unit, it may be clogged.

Uotside unit blowing cool air but hot on the inside


It sounds like you have a unit called a heat pump. When a heat pump unit is in cooling mode the outside unit blows hot air and the inside unit blows cold air. If the outside unit is blowing cold then the indoor unit is most likely blowing room temperature or warm air. It sounds like the thermostat could be controlling incorrectly or you could have a failed reversing valve which is the device that switches the unit from heating to cooling mode.
