Could be a stuck open thermostat or low on coolant or the temperature blend door is faulty.
THE CAUSE for this is that when your cold air is on the petrol is used to create air. and that is how cars create cold air
if it's the outside unit, it will always be hot air. that's the air being pulled out of the house. cold air in, hot air out.
check your thermostat first
dual control damper needs replaced how do you change it
It doesn't really blow it out it just warms the cold air.
An air conditioner blows out heat
If it does blow just not cold air you should see if it needs to be recharged
Check temperature control cable for binding.
why does ac blow warm air? why does ac blow warm air?
No, not if it's on a heat setting. Most home thermostats have a "Fan" setting that will blow cold air if the attic is cold.
i hav the same problem
It could be caused by many reasons. First you have to see if the coolantlevel is full, and then when the engine reaches operating temp, is the coolant hot or cold.
