SOURCE: Problem with GE Zoneline 5200 model

Heat pumps have saftey circuits that prevent liquid flooding of the compressor. Inadequate airflow across the evaporator in cooling can trip this circuit. Have your package unit serviced with particular attention to cleaning the evaporator coil and be sure your filters are clean and changed frequently in the summer months. Hope this helps GL!

SOURCE: Bryant Legacy Line air conditioning not blowing cool air..

Your outdoor condenser is in heat mode. Check the wires on the thermostat. Sounds like a small wiring problem and nothing else. Good luck. Please keep me posted as to you progress.

SOURCE: Will not cool properly.

You have either a faulty thermostat, dirty condenser and evaporator or a faulty run capacitor. Need to service soon before the compressor is damaged. Sea Breeze

SOURCE: Air conditioner blowing only warm air

possibly have a capacitor out on the compressor side of the a/c Since the unit works and its only blowing air the compressor isn't kicking in. The capacitor boosts the compressor to activate the compressor. I would have the capacitor to the compressor replaced first before going any further.

Good luck on your repair

Amana Wall unit blows cold air before heating


the unit works by chilling air and the byproduct is heat in the compressor, this is used for heating in the winter and then reversed in summer to blow cold air. It has to blow cold and warm up before it can blow heat.

My Honeywell thermostat isnt keeping my house cool even though the temp is set to 69. Currently 90 degrees in here


Its probably not the thermostat. The air conditioner may be stuck on heating mode. If its a reverse cycle, the reversing valve may be jammed so even when the thermostat is calling for cold air, it stays on heat. If the machine is on heating mode, it should be blowing cold air out of the outdoor unit of the air con. If its on cooling mode, the outdoor should be blowing hot air.

Unit blows cool air while in heat mode


model number? Heat pumps tend to blow cooler air than a space heater unless in money-gobbling mode.

Using as heater and unit is blowing cold air


A heat pump is an air conditioner that reverses its refrigerant flow. In the cooling mode, the evaporator is cold to the room and its condenser is hot. In the heating mode, a valve reverses the refrigerant flow and makes the evaporator warm and the condenser cold.

My dehumidier blows very hot air while working. Makes it hotter than it was before starting. Like a furnace.


It is normal for a dehumidifier to discharge warm air. A dehumidifier is really an air conditioner - a fan blows humid room air across a cold fin coil that causes the moisture to condense on it and drip into a container - thus cooling AND dehumidifying the air. The cool air is blown over the warm coil and discharged out the back. A dehumidifier WILL normally increase the temperature of the room it is in.
You can do the same thing with sitting an A/C unit on a stool in a room. Room air will be drawn in, cold air will come out the front, hot air out the back and water will drip on the floor. And, the room will get hotter, due to what is called "heat of compression" even though you're running an A/C unit.

My mistral reverse cycle mss25ss model does not work at all in heat mode. what would be broken?


firstly is the air comming from the outdoor unit cold or warm? if it is cold then the 3way valve is working and it has changed to heating. If it stays warm then it is still in cooling mode. The indoor fan wont come on until the coil temp gets warm enough, ( so it doesnt blow cold air on you straight up). If it is changing into heat mode then the larger of the pipes connected to the outdoor unit should get warm/ hot. If this is not happening then the unit is either out of gas or the compressor is on hollidays and wont come back to work.

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.

Our brand new kitchen aid oven will blow hot air for up to a half hour after it has been turned off. This seems unusually long- what is the expected time of cooling off?


Hi,
That depends on the ambient temperature in the room..if your room is fairly warm you can expect it to take longer then if the room is cool...
I would say though that 1/2 hour is pretty normal...it is good to get the unit cooled down, the less time it is warm the longer it will last... heat kills ovens...even though they are made to take heat...

Blowing out warm air


Turn thermostat switch to 'cool' setting. It's a 'heat pump' and is in the heat mode.

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.
