I apologize in advance for what may be a long read especially on my first post here. I've read some other threads and have some idea of what I could do but it's an apartment so I'm limited on what I can do: The Skinny: top floor (2nd floor) of an 8 unit apartment (4 top, 4 bottom) Been there for over 5 years. Last 2 years have had a 3rd person who doesn't leave much. It's about 1300 SQ FT. Large living room upon entry. Faces South and West. Kitchen/dining area to the right. Thermostat is on the wall between the living room and dining room (also happens to be the hottest place in the whole apartment). guest bath just next to dining room, and 2nd bedroom then large master bedroom/bath to finish it off. The Master isn't all that bad though it has south and west windows. 2nd used to be cool but with a person in there 24/7 it's gotten really hot. We are in AZ so, well you know. I had a 2 floor condo prior to the apartment and it was never this bad. We have had many thermostat and other issue with the unit. It's the 3rd thermostat since we have been there, and the unit is unknown for age. Last August we had it recharged as it was actually empty and then earlier this year there was a coil replaced. We replace the filters ourselves with the 30 day ones. It's a ceiling placement in the hallway between the bathroom and bedrooms. It is also extremely loud. There is a vent in the dining room, living room, the 2 bedrooms and the bathrooms all are high up near the ceilings, plus we have ceiling fans in all the rooms. The living room cools off very quickly as do the rooms. The dining room does not. We have floor fans running all the time, we installed black out curtains a few months back after getting in trouble for having something else up for a year. The living room has a LARGE glass Window/sliding door which gets extremely hot. The other bedrooms have oversized windows/screens but I really think they are only single pane. Before the 3rd person we would just raise the thermostat to around 90 or so while we were out, and it would actually come on a few times during the day. I used to place thermometers around to gauge how hot it gets in certain places. It was not a fun experiment. Now I have a floor fan aimed at the thermostat basically all day. It usually keeps enough cooler air from the living room over it so it doesn't run all day. The moment I move or turn off the fan, the AC kicks on. This time of year I cannot get it below 80 unless I run it for 8-10 hours straight. When the air does run and cools off to where the ac can shut off, the other rooms can be freezing. Within minutes though the AC will kick back on because the area around the thermostat is beyond hot. My bills have skyrocketed over the last few years. I put a 2nd fan on the dining room area to blow around that hotter air into the kitchen or down the hallway. I'm just at a loss at this point on what to do. We are either too hot, or too cold and have to fiddle with the unit all the time. The latest I tried was to install a casing over the thermostat and use ice packs to keep it cooler, so far that has not worked. (either inside the case or on top of it) I'm hoping someone might be able to lend some helpful advise. Maybe I need a window type unit for the 2nd bedroom/dining room or one of those portable ones, maybe I just need to be freezing something and have it by the fans. Do I need an evap cooler instead? The last few nights it runs all night to where I have to keep getting up like every hour to slightly raise the temp. I had it around 85 this morning by the time I got up for work, had to lower it to about 82 for when I left and the AC was still running. This was before 7am! I'm also sure that whatever is above us for the roof/attic/crawl area is not insulated at all. We have received mixed answers from the apartment and they don't seem to understand how hot it really gets in there, they just aim their little lasers at the vents and nowhere else. Sorry for the long post and I do hope there is an answer. I still have about 6 months left here, hopefully not more after that.

Hi, I purchased two air-con ACN12-12HPCEV/ACN13-12HPCCO units 4 years ago. My one unit is now not working: When in air mode, unit starts flashing 4 lights about 1/2 after being turned on - manual show 4 lights as (abnormality of outdoor unit) after about another 1/2 hour unit shuts off. When in heat mode, it does the same but no heat comes out. Just a cool fan air and the vane control does not work. Was told that the inside PC Board needed to be replace as it is not reading the control modes correctly. I'm just curious though as the 4 lights blinking indicates its the outside unit not the inside. The part is $200 from air-con not including installation. Local Air Conditioner companies want more. I hate to spend the monies if that is not the case. I was also hoping I could find the part cheaper but have had no luck searching it on the web. Before the units, I had not had much luck with our local ac companies and why I am questioning. They always take me to the cleaners here. Has anyone else run across this problem or have knowledge that would be helpful to me before I purchase the part. Thanks, Joan Marie
