I have an LG wall unit in my sun room. Geicos are coming into the room through the unit. Do you have a screen I can use to keep the Geicos out??

Some thermostats have a five minuter time delay to protect the A/C when power fails. Some units also have a time delay, if so both must be satisfied before it will start.

You didn't mention the make or model of your TV but most of the latest do have an ECO setting or similar idea in the set up or picture menu, this means the screen will automatically adjust the picture brightness if the room starts to get too bright, as in the sun shining or if the room gets too dark. Take a look in your instruction book for this type of setting, remember not all models have this & yours may be one of them.

It very well could. Particularly, if the humidity is high and the AC unit is in direct sun light for 6 hours or more per day. If that's the case and it's either a window or thru the wall unit. Installing an awning over it will help.

Make sure you have set them correctly IE/ If you want them to heat, make sure the heat symbol is dispalyed and the temperature setting is above the room temperature. Press the "house" symbol on the remote to find the room temperature. LG as with most other brands , if set to cooling but the remote temp is set high ( 20 to 25 degrees,) will run for a few minutes and then turn off as the machine thinks it has reached the temperature you have selected.. Heat symbol on LG is a "sun", cooling is an icicle. Check your filters.... if they are dirty, the units will not operate correctly.

Keep heat mode and set temp +5 than your room temp. Helpful?

well, these heaters are typically thermostat-bound, and I have found that they simply will not burn continuously, like a blue-flame heater. Try turning up the setting--this will make it come on/off more often, effectively heating at least one med-lg room, and partially for adjoining areas. Keep in mind that these only rated for 700-1500 SF--that is NOT the floor measurements, but square feet of airspace; eg., a 10' x 15' room has 10' x 15' x 8' (8 foot ceiling) =1200 sf. That said, My 15k btu wall unit had been the sole heating source for my entire home for 5 years, until last year, when I acquired another smaller unit. However, I typically only use a few rooms, and shut off unused areas (ya, was 'cool' in unused back room areas).

either going off on low charge which would cause it to ice up, which means you need refrigerant. or high head pressure might just have to clean the coils or check condensor fan.

Lowering the temperature setting doesn't change the temperature of the air coming out of the unit it just lets it run until the room temperature gets colder. Check the temp of the air coming out of the unit. If it isn't as cold as it used to be the charge could be low. First though you should make sure the filters are clean and the coils.You should also check the actual room temp. It's also possible the unit doesn't have enough capacity to keep up with the cooling load of the room.

Is there any magnets around? Does the sun hit yhe screen? Could there be a recall on it?

there are units on the market that will work great, one is called a Mr, Slim, look it up on the internet and find a dealer in your area that carries them and check them out.
