its the gas flowing into your unit that produces the cold air the gas is cold so your pipe slightly freezes
if you have the ac on to long it starts to stink cause the filter picks up the smell and the smell spreads i suggest you get it cleaned
The most common odor problem from a window ac unit is that there is a buildup over time in the drip pan. The pan collects condensation and allows it to drain through a hole in the ac unit. Over time the pan will collect dirt and other particles, and can develop mold. With the ac unit unplugged the cover will need to be removed, and the pan scraped out and washed.
Yes. They are.
Big.
There will be ice on your AC lines if the pressure has dropped too far. Freon has a much lower freezing point than water and will freeze condensation quickly.
Usually capacitors in an AC system are there to improve the power factor. Transformers are used to increase or decrease line voltages.
The one that is in the biggest line, You have a small line and a big line. The big line is the low side, and the small line is the high side.
on the dash
Its helps in oil return if the refrigerent line is too long
You will notice Ice on the line going from the a/c unit or somewhere along the line insie the house
Any refrigeration or AC evaporator coil has a tendency to ice up when they get cold. Water condenses on the coil when the air is cooled. That water can then freeze. If an AC system is operating correctly it will cool the air and eventually when room temperature reaches the set point the AC unit will turn off, this give any ice that has formed on the evaporator coil a chance to melt. If the system is low on charge, the room may never reach the set temperature and therefore will not shut off. The ice will continue to build on the evaporator coil until it is completely iced over. A dirty evaporator coil can cause this as well, so change your filters often. Another possibility is the ac system has to be matched to room or house size. Too small and too large a system will both cause you problems.
Connect a freon gauge and freon tank to the low side ac port. With the engine running and ac on high, open the freon tank to fill the system to the full line on the gauge.
There isn't an "AC drain line". Refrigerant is recovered through the schrader valve on the high pressure side. Servicing an AC system is not a "do-it-yourself" task, especially when it comes to recovering, handling, and storing refrigerant.
You probably have a leak in the AC system or the AC compressor failed. Mine had metal particles in the AC lines that prevented fluid from flowing and practically blocked the AC flow. This is a filter in the AC line right under the AC condenser attached to the frame. Any AC shop charges $75 to check and diagnose.Any car AC system has seals and with age they fail.
