Make sure your air filter is clean. A dirty air filter can block air flow. If both the fan and the compressor are coming on, there may be a low charge. If only the fan is coming on, the compressor could be burned up.
there is a leak in the compressor...
low on refrigerant or the compressor isn't running..
check to see if the thermostat is hung open or your temperature sensor for your fan is out and causing your fan on your radiator to run continuously when key is on.
No. Running an air conditioner on fan does not cost as much as running on cool.
central airconditioner makes a clicking noise when running? any idea what to check?
Condensor is overloading. Had the same problem last year.
You will use more gas when your air conditioner is running.
If it's a central A/C system, the best advice would be to find a comfortable temperature, set it and forget it. Also turn the fan switch on your thermostat to "Fan-On". The constant air circulation helps to even out temperatures inside, even if the outdoor unit isn't running.
Because it's pumping freon through the pipe and its freezing cold
keep it closed the windows .but if need fresh air from outside , open the windows.
Check your furnace fan. The air conditioner unit can be running but the air circulation is usually done with the fan on the furnace. If you have a fan switch on the thermostat, check to see if it is in the auto position. If it has the settings on/auto/off, you can switch it to the on position and see if you get any air movement then. If not, you could have a broken belt.
Your air conditioner should have a built in thermostat and cycle as necessary. The air conditioner takes a little while to reach peak efficiency. Once the room is cooled it will cycle on and off as necessary. If you manually cycle the air conditioner, you are greatly reducing its efficiency.
