Question about Haier Heating & Cooling

Open Question

I have a Haier HWF05XC6 for about a 120 sf room and it does not seem to get cool enough in the middle of the night. I checked the filter and cleaned it out last weekend so that should not be a problem. The unit itself is about a year old.

SOURCE: my frigidaire window AC is not cooling anymore

Does it get cold? You can try cleaning the fins-both inside and outside, with windex. Smoling & cooking will create a sticky deposit that will make dist that gets through the filter stick and it won't cool properly.
If it doesn.t get cold any more, try replacing the starting capacitor. About $5. If that doesn't take care of it, just replace the unit. They are cheap enough these days, that you can replace a unit with a more energy efficient unit for the same cost or less as a repair would cost.

A few basic principles for air conditioner troubleshooting. For both central home air conditioner or window air conditioner, the first thing to check is whether the unit is getting proper power. If the unit uses 220 volt power be sure that the proper voltage is getting to the unit. Same for 110 volt units. A voltage meter can be used to assure that the voltage is correct.

For window air conditioning units the voltage can also be checked before and after the thermostat. If voltage is being supplied to the thermostat but not from it then the thermostat probably needs replaced. This is a fairly common problem. Another place to check is the fan motor voltage. The fan on window air conditioners runs both the indoor blower and the condenser fan. If that motor fails than the compressor may run for a short time, but will overheat and shut off. Continued operation like this will result in compressor failure. This motor can be economically replaced for larger window air conditioners, but for smaller ones the cost of replacement will be more than a new unit.

Central air conditioners for the home are more complex and there are more things that can go wrong. As with the window air conditioner the thermostat can also be a problem. The central air conditioner thermostat will only have 24 volts going to it. So don't look for high voltage there. Some units the voltage will be coming from the outdoor unit and others the voltage will be supplied by the indoor air handler or furnace. Most home central air conditioning will be supplied by the indoor air handler or the furnace. If the air conditioner is for cooling only the unit will usually have only two wires going to the condenser unit. Make sure that you have 24 volts across those wires.

The next thing to check will be the indoor blower. If your thermostat is calling for cooling then the indoor blower should be running. If there is no air moving across the indoor cooling coil then you will soon have a big block of ice formed on the coil. This can happen for a few reasons. The indoor blower is not working, the air flow is restricted and not allowing air to move across the coil. A clogged air filter would also do this. Or the outdoor condenser unit has lost the charge of refrigerant.

Finally and worst of all is when you have a complete compressor failure. Often when this happens the compressor will "lock up" or not be able to turn when power is supplied to it. Overheating or lack of lubrication are usually the main causes of compressor failure. Overheating can be caused by the outdoor coil around the compressor getting clogged with dirt, leaves, or grass. Loss of the refrigerant charge will also cause the compressor to overheat. It is the cool return gas coming back to the compressor that helps to keep it from overheating.

As you can see there are many things that can go wrong with an air conditioner and I have not come close to exhausting the possibilities here. I have just touched on the most common problems in a very basic way.
There are some basic trouble shooting things that can be done very easily. Most problems are above out of the range of comfort for many homeowners and professional help should be consulted before any attempt is made at repairs. Remember also, that the release of refrigerant gases into the atmosphere is a federal offense in the
US. Proper care must always be taken to minimize the release of any gases. A license is also required to handle refrigerants. Make sure that the professional you call has the proper certifications to handle refrigerants properly.

Bring it outside or to your tub and tip it on a 45 degree angle some water will drip out...once a puddle has come out of this thing it will work again but u will need to properly drain it eventually unless u wanna tip it and drain it every few days. But thats what ive been doing with mine...

SPLIT AC CONDENSER TRIPS AFTER 1 OR 2 MINS, ONLY DURING THE DAY TIME


The condensor is not cooling fast enough. Try cleaning the condensor coil. Also check that the fan goes on. At night the outside temperature is cooler and does not need much work to cool down the condensor.

A/c seems not to working cooling down room What are my options?


Could be several factors. Let me start by saying the unit you have should cool a room that totals around 450 square feet (Approx.).

If you do not know your rooms square footage just multiply the width of the room x the length of the room.

(e.g. 20' x 10' = 200 SF)

The above 450 SF is for a room with typical 8' ceilings. This is also a "Rule-Of-Thumb" measurement, as windows, doors, insulation, and air leakages (heat gain) also play a role in calculation of heat loads. But this will get you close....

If the room is larger than 450 S.F. in size then the unit is too small for this size room.

A rule of tumb for sizing is: every 600 square feet requires a ton (or 12,000 BTU) of cooling. Again, without doing a proper load calculation on the room or area being cooled, it is hard to be exact.

The other possibility is the unit is not operating as it should due to mechanical or other issues. This is hard to specify. COuld be refrigerant levels are low, coils dirty, or filter dirty.

I have a Haier ESA3085 that I set the temp to go to 73 degrees and even lower but does not go below 77 degrees, what can be causing this?


The unit could be low on refrigerant. It could have a clogged evaporator or condenser coil. It may not be big enough to carry the load of the room it is supposed to cool. Usually the biggest problem with all air conditioners is they need cleaned. I would check this first.

Haier room air conditioner doesn't cool maximally at "Hi AC"


You should have at least 5,500 BTU's for that size room. Clean the filter. Turn it on and let it work for a few hours.

Ac ices over


First you need to make sure the filter is clean to allow good air flow through the evaporator. If the filter is clean make sure the evaporator is not plugged up with dust and lint. If all that is ok your problem is the a/c BTU's is to big for the size room you have the a/c in and it is getting the room too cold. If that happens the evaporator will ice up and will not cool the room.
