I have central air and I was wondering how do you put freon in it because its not blowing out cool air


Is the compressor starting? On the outdoor unit you will see a large copper pipe and a small copper pipe. Is the larger of the two cold to the touch? wet? Just because a central air system is not blowing cool air does not mean it needs freon. If you have clogged filters it cannot do an air exchange. So, I would recommend checking the easiest things first before adding Freon.Most people make the mistake of adding Freon and overcharge their system. In a low load situation you can slug the compressor with liquid and your system is ruined. If you do have to add Freon it indicates that you have a leak. An AC System is a closed system and if it is working properly you should not have to add Freon.

My central air conditioner is making a whistling noise in the inside unit when the compressor is running. It's not the blower because the noise stops after the outdoor unit shuts off. It's also not blowing...


Hello,
If there is no cooling (meaning no cold pipes and not blowing cold air) then check the outdoor A/C for any visible/obvious issues; breakers not tripped, no debris blocking the outside unit from passing air through it, etc. If all looks ok, you can start checking some things inside of the unit if you feel comfortable doing so. Also, most indoor heaters have a higher speed/rpm for the fan when the cooling kicks on, and the heat runs on a lower speed/rpm.

Hope this helps James

Air conditioner not blowing out enough cold air fan is working but frost is built up outside and in on lines


Sounds like the unit may be Short on refrigerant, the frost can be sign the refrigeration is taking place on the pipework between the indoor and outdoor unit and not on the internal coil (evaporator indoor unit)

All the best

Tempstar High efficiency 5000 It is not blowing enough cold air


if the unit has cooled fine in the past then it is most likely dirty you need to look at the return side of coil,you may be able to look thur your return grill.if it is dirty it is best to call a a/c service company to clean it for you,what ever you do,Do Not clean with a brush it can damage the coil and cost a lot to replace.also check your suction line at outside unit,it the big line it should be sweating if not it can be low of freon. Average cost to pull and clean a coil is about 375.00 no more then that.

Poetable AC compressor licks in for 10 min


It is probably either the high pressure switch or the frost control. The high temp switch usually trips because the condenser coil is dirty which does not allow it to exhaust heat very well. The frost control will trip if the system gets below 39 degrees on the pipes. This is usually do to low refrigerant or dirty filters. Good Luck!

A/C does not blow cold air. It has frosting built on the pipe that connects to the a/c unit outside. There is some water built up where the filter sits. I turnd off the a/c for a full day, the frost...


Shelly,
Most likely you are low on freon. Your air conditioner uses a coil that gets cold when the freon passes through it to produce your cooling. The temperature of the freon inside the coil is directly controlled by the pressure of the freon. When the system is low on freon, it causes the coil to become to cold and then instead of sweating it freezes. You will need an a/c technician to reslove the problem for you as the task requires tools and equipment that you most likely don't have.

Thank you,
Chillmaster
