    Gandy, are you sure of the Model Number you listed? In all my data, I can't find a Goldstar AC Model Number even close to what you listed.

Hi, if he is a a/c tech, he had to use silver solder to repair the leak. If he is using manifold gauges, he can charge it with out knowing the amount to put in by looking for how much it takes. The unit needs/HAS to be evacuated first! He can charge in the freon using the chart on his low side gauge, as he wants the evaporator temperature to be at 40degrees F, with the P.S.I. at 68 for R-22. Just start charging in, using gas not liquid slowly, watching the suction line, and stop when it starts to condensation the line. If the top of the compressor starts to condensate, it is over charged. I wish you the best.

Room does not cool down


It may be low on freon or have a leak, I'm not sure if that particular unit has Service Ports on it to enable a recharge, consult your Owner's Manual for any Troubleshooting Tips. www.goldstar.com

Rv air conditioner problem


this is true...freon does not fade or get "used up" if freon is needed there HAS to b a leak.
heat strips are very expensive to use....option for the heat pump heating which will only use as much electricity as the a/c side.
heat strips= 220 v X 10kw= 22 amps compared to a compressor at ie= 10 amps.....typical draw for 18,000 btu

How do you add coolant to a goldstar air conditioner


There are two lines leading into the unit, the high side aND THE LOW SIDE. tO ADD FREON you need to add a valve to the low side line. But if you have a leak that indicates that moisture is in the unit and you need to pull a valum to remove the moisture before ADDING ANY FREON. There are as last known three types of freon, R22, R134a and this last one I dont even know the name.

When turning the theromostat to 9 it doesn't cool the room.the fan just runs.


the system either low on freon or you have a bad leak. If its low or have no freon the unit will keep running. have the unit recharge and check for leaks.

Air conditoner model gwhd5000 goldstar does not cool


Hi, first you will need to know, what type refrigerant,(freon) your a/c used, if you need to add freon, there's a leak in your a/c. you will have to find and repair leak, before you can charge/ add refrigerant(freon) . automobile a/c can be easily recharge (add) to system, but your window a/c unit, has the same principles but different approach, if you don't have experience, you will have to call mechanic, make sure you have a freon leak, before calling mechanic, plug a/c on let it work, put hands close to a/c, feel or check temperature of air blowing out from a/c, make sure compressor is working/running, fans could be working/ but compressor not, also put a/c thermostat to max, your model no. GWHD5000. means your unit is 5000 b.t.u, (british thermal unit) measurement of heat transfer, am wondering if a/c is to small for your space/room. making you think it needs freon, 5000. b.t.u. is for a small space,like a room 10' by 10' like a storage area or small bedroom, keep bedroom door/windows shut. measure you room/space/area , the bigger space/area needed to be cooled, has a chart, maybe you can find it on internet, any way a 10.000 or 12.000 b.t.u a/c is better buy, for normal room/space etc. so check compressor especially to make sure working, a/c could be to small for space/room, check it at night to see if it's colder. don't try to put gas/ freon yourself, could be very dangerous. but before calling mechanic, check those thing, mention before, could be your a/c are to small, for space/room etc. remember before attempting any repairs, disconnect power. good luck.

Goldstar GWDH 5000 does not cool after storing this winter


sounds like low freon or a blockage in one of the lines, especially since the you say only one row of coils is cool. usually window a/c's have at least a 1-year warranty and since you are pretty close to that, the manufacturer may honor it. if not you will need to have the system fitted with a bullet piercing valve on the low side lines and see if the unit is low on freon with proper gauges. if it is not showing low then there is probably a blockage and the high side should be checked as well. if this unit was an expensive one it could be worth having it repaired. a simple recharge may cost less than a replacement, but anything else probably won't.

Why will a room air conditioner ice up and can I fix the problem?


Freon leak, How new is it. If you still have a warranty take it back and have them replace it. If it is not under warranty you can try a few tricks. Clean the outside coils with a strong blast of water with the unit off and make sure the filter is cleaned

Air conditioner freezing up


Your unit is low on freon. Take the unit to a service facility & have it recharged & the leak repaired. Note that ice formation may normal if the outside temperature is below 45-50F. If you must use it in the meantime, leaving the unit on fan only will melt the ice much faster.
