The most obvious reason is that the gas, which is responsible for the cooling effect has leaked out of the tubes. So call the nearest mechanic for attending the gas leakage and re-filling of the gas. If gas leaks again and again, get the complete cooling coil replaced.
Central Air Conditioners are installed into your house to provide cooling air in every room using a duct system. They are very refreshing on a hot day.
An air conditioner blows out heat
If your air conditioner blows air but it's not cold air then you probably need freon in your air conditioner
There is no such thing as and air-conditioner accumulator in an automobile. A nonworking air-conditioner compressor can cause a cooling malfunction.
The Air Conditioner is on
Well the main reason why your car blows out cold then hot is because the air conditioner may not be working properly. You should go to the car shop and get it fixed.
If the air conditioner is on but not cooling the house properly, you may have a leak in your duct work. A leak would allow all of the cold air to escape, blowing into the outdoors instead of cooling your house.
Why is there humidity in the room when air conditioner is cooling? Room feels damp.
the system is probably out of coolant.
Alternator air conditioner air cooling system
Actually a refrigeration compressor is a component of an air conditioner. The refrigerant used in an air conditioner is called Freon. The compressor in an air conditioner evacuates the evaporator providing cooling to the air.
If the ambient (air) temperature rises and the A/C blows warm air, it probably means that you need to add freon.
