Is the compressor running? It can take awhile to re pressurize the system after storage sometimes. If the compressor is running it could have a leak and lost it's charge. If the compressor is not running It could be the thermostat(jump it out) or the start relay. Not many choices for these.

There are really only a couple of reasons for this problem, 1st make sure the AC compressor is running, if not u may have a loose of power problem, next problem is a low system refridgerent charge, this can be tested with a set of AC guages, low side pressure with a stable system at about 80 degree's F should be about 30-32 PSI at the low side line of the compressor manifold, U didn't say what type of unit this is, but the above procedures for checking lack of cooling are the same for all AC units.

Haier window ac constant red light? No label next to red light. Turns on and off fine. Cleaned filter, no change. couple years old. Still cools down the room but not as cold as it used to. Help?


Sounds like the unit is just dirty. The AC pulls air through coils and contains dirt, pollen, grease and all type of pollutants. These contaminants will cling to the coils, reducing the AC ability to transfer heat.

Here's a great YouTube video explaining how to properly clean a window AC. How to Clean Window Air Conditioner

AC units should be cleaned every year (including the whole house units), to maintain their ability to cool efficiently.

It cools great when first turned on. After so many hours of cooling it stops cooling


Have you checked up in filter area at ceiling to see if fins are frozen or frosted bad? If they are dirty, they can cause frost/ice and AC goes in to fan only until frost/ice is gone. When did unit actually get a good cleaning last? Too many registers closed or blocked can cause freeze up as well. Does this unit have ducted or non-ducted system?

Hi , was working fine last year but now is now


There are 5 basic, yet solvable reasons for what you described. Please pay particular attention to numbers 1 & 2.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

Hope this helps you troubleshoot & solve the problem. Thanks for choosing FixYa.

We have a dual therm dometic air conditioner on top of a livestock trailer. Air only no heat. It has been cleaned and very clean filters. Always has worked great this year got ready to start up and will...


Unfortunately this will require some specialty tools and most people don't just have them in the garage. The unit definitely has freon in it or used to. These types of unit never tend to have valve you can add refrigerant through so someone must add them. I would try to check with a local HVAC company. Sorry about the bad news.

Had unit for 4 years do not use it awhole lot put


Good job, on cleaning the air intake filter. Some folks overlook that. Since that helped some, I believe you need to clean a little further. Like the cooling coils and the cooling fins for the compressor. But, before attempting any cleaning turn the Master ON/OFF Switch to OFF and unplug the unit from the wall outlet.

You can clean the coils with warm water and liquid dish washing liquid,. Rinse and dry thoroughly. When dry, apply a light coating of WD40.

The fins can be cleaned using an old toothbrush and a vacuum cleaner that has a hose and brush attachment or crevice tool.

Completing this Annual Type Maintenance should provide significant results.

It takes more then 30 minutes to drop 1 degree after the outside unit was charged to 200 psi of freon last year on may 28 2008


Air filter needs replaced, if the air is low flow but cool out of registers.
Need to find the leak in freon line if air is not cool.
Clean outside unit if either one applies.

Ac not working like it used to


Storing the Unit is important -it should be up-right NOT on it side, this will cause the iol to clog the lines, NOT COOLING properly could be it need a good cleaning ( with a cleaning agent and a hose ) . to do this you have to remove the case or from the sleeve, BE CAREFUL NOT TO WATER "ELECTRICAL PARTS, clean drain line ( condensation "water" will cool off the ouside coil ( candenser) the inside coil can frost up if dirty or filter is clogged.
take the Unit out and clean well. you can purchase a spray that will remove all the grease and dirt - be careful not to bend tubing. use a light spray and let it dry in the sun. When putin Unit back in the window or wall WATER MAYBE SPRAYED OUT -DON'T STAND IN FRONT OF THE UNIT - IF you can't do this, call a serice company - this job can be done in a back yard.
