SOURCE: WATER LEAKING FROM MY SPLIT TYPE LG AIRCON

1. Do not set the aircon too low temperature in overcast weather, this will cause ice ups and water dripping. Optimal comfort zone temperature is 24c.
2. You need to open the grill cover on the front of the aircon which unclips either end left and right with a finger pressure. You will find two filters which can slide out and should be cleaned. First tap them together to remove dust, then you can wash them with mild soap and cold water.
3. There is the third possibility that an insect has made a nest in the drainpipe. You should look on the outside of the building and locate a plastic drainpipe. You can either blow into this pipe with your mouth or get a blower. This will unblock any restriction in the drainpipe.
Goodluck and ratemeplease.

SOURCE: New 14 seer split ruud heat pump makes very loud knocking noise

Well you may want to have a tech come out and check the freon level, but mostly when going into defrost, some units make alot of noise, the freon is reversed in the unit by way of the reversing valve, it makes a whooshing sound like freon is draining off, as far as the knocking noise, could be as I said in the beginning, might be low on freon, but it could be that, this particular unit does this, I have had units make some really strange noises in the past but functioned perfectly, hope this helped, please let us know, thanks again,

Hi I keep getting a ch 67 after the unit starts fine and runs for like five minutes fan on all units work during that five minutes any thoughts would be greatly appreciated


Low freon pressure switch is turning it off. As the coils cool down the pressure drops. As time goes on it will run shorter and shorter cycles. In warm weather freon 22 low pressure should be near 70 lb
410A freon about 150 on the low side

Aircon stops after few minutes without having the room cooled the correct temp.The compressor does not start .We have to wait for a long time after shutdown and restart for it to cool again. If not


Most possible reason in this case is defective compressor(it overheats),or not enough freon in the system. Solution 1.change compressor;2.Recharge the system with freon.

Is there a universal gauge set for all types refrigerant


The most common manifold are only for r-12 and R134A. Because of the pressure differences between that and R22 and R-410A ( and the manufactors make more money by keeping the types of manifolds seperate). I haven't seen a universal manifold that would cover all types freon.

Chargeing Unit


The old 410A fittings are different than the r-22 fittings. There are adapters available on ebay. Remember 410A runs at higher pressures than 22. Be sure to use gauges for 410A! Use the right gauges with the right hoses! High pressure.. Use the right gauges and the right hoses!

What should the pressure readings be for a American Standard Freedom 500 2.5 ton air conditioner be


Hi, this depends on the outdoor air temperature and type of freon this unit has. The hotter it is outdoors, the higher the pressure will be as they use a pressure/temperature relationship. If the unit is R-22 and lets say it is 90* F. out side, the low side or suction side will be at around 68 to 72 p.s.i which would give you an evaporator temperature of 40* F. Head pressure would be at around 90* plus 27*= 245p.s.i. This is if the condenser fan is in good condition and the outdoor coil is clean. If you are using a set of manifold gauges you have the pressure/temperature scale right on it. If the unit has a TXV for metering, you would need to charge it using the subcooling method. On a Non-TXV you would use the superheat method. If you are using the new R-410a freon, the pressure are extremely high in these systems compared to the R-22 system, so make sure you look at the units data plate to read the type of freon. The color of the container is green for R-22 and a Pink for R-410a and the 410 a unit will display a pink warning sticker on the unit to tell you. The pressures on the R-410 would be at 90* F, low or suction side at that temp is around 125 p.s.i., and around 400 to 420 p.s.i. on the high side, much higher then the R-22. You would also need a manifold gauge set made just for the R-410a (AZ-20) as of the extreme pressures in the system. There is never a set pressure to go by as the outdoor temperature will raise and lower the pressure of freon very fast. If you are asking this question because you have a manifold set and are taking a reading, the unit has a charging method pasted right on it from the factory showing what pressure they want it to run at. Your gauges also can be used as a pressure temperature chart, or you can pick one up free of cost at a a/c parts house to keep with you. It will show you how to calculate the charge for your unit. If you are familar with pressures, this should be of a great help to you. I hope that I have helped you on getting the unit charged properly. Please keep me in mind when rating me, as I know you will be kind. Just drop by a wholesale a/c parts house, walk in and ask for a pressure temperature chart, and they will hand you a couple of them. They have very good information and no how on all of the most common freons in use today.
Best of luck

What freon 134A


The freon in most ice makers are R 410a at this time. You will be able to find the type of freon your model has listed most times on a data plate on the rear of the ice maker cabinet and on or near the compressor. R 134a is not always used in production ice machines because it does not freeze water as productive as
R 410a. The type oil in the compressor also will lead you more in the direction of the type of gas. Now If you need to replace the freon or compressor I can help you determine the exact type of freon gas was existing before the change, Let me know if this has answered your question. Thanks, Sea Breeze

Hitachi Soleus split Not blowing cool air.


if the freon is 410a the pressure must be 100-120psi,if it is 22 the pressure must be 45-55psi.you unlucky because hitachi havent problems with compressors.is it inverter the unit?if it is you must check the outdoor pc board,if the 4valve clicking in the you must replaced it propably has stucked.
