Haven't gotten a chance to try this yet, AC guys are coming tomorrow.

I'm sure it doesn't help that my father keeps the thermostat on 71 F all summer long. However, the "bad" room is around 75 degrees. The "good" rooms in the house are a steady 70 degrees and are noticeably cooler.

This is only the evening. I will report back to see how things are during the day.

BTW you may be able to run the fan continuously via the thermostat. If you put it on "cool" "fan on" it may be wired to run continuous low speed then go to high speed when thermostat calls for cooling. Have you tried that yet? The fan is designed to run on continuous "low" speed OR next to low speed. This is normal especially in two story or difficult cooling applications. Either way if you try it for a day or two it will prove a point. If your AC cycles on and off then capacity should be OK. If it couldn't satisfy the rest of the house i.e., stays "on" all the time, then it is a sign of it being too small. Also, even if this causes extra wear on thew motor it may only cost about $25/yr. to replace in 5 years instead of 10 years as an example.

Can't wait to hear the outcome. GOOD LUCK!!

So, you want me to leave the fan on for 2 days? This is supposed to just circulate the air, correct? Also, a new HVAC guy stopped by and said the problem is I have no dampers. He recommended installing electronic dampers and thermostats in all of the rooms. He said this would solve the problem. It would almost cost almost 5 grand. Crap, for 5 grand, I can get one of those Mitsubishi mounted units and turn my room into the north pole. O.o

While I agree that installing dampers on every run, and thermostats in every room, would resolve the problem, that's like using the proverbial sledge hammer to drive in finish nails

There's lots of houses out there with no dampers that cool just fine. You need to determine the root cause of your issue, which is likely an undersized unit or poor duct design. AFTER you resolve that, you might then consider zoning the system - but as you've seen, that can get quite expensive.

I meant ...run the fan continuously while the AC is "on" it's normal operating cycle. This negates the use of dampers because it will eventually recirculate the air throughout the house resulting in even temperatures throughout. If the AC and duct work is anywhere near being sized properly then all rooms, including the "south" will even out to the set point on the thermostat. You may already have the setting on the thermostat, i.e., set at "cool" "on" which should result in the fan running on low speed continuously then kicking in to high speed when the thermostat calls for cooling..Don't listen for a voice calling..that is a term that means when the room temperature increases the thermostat sends a message to the compressor and associated components to turn on creating required cooling..OK?...If your thermostat isn't wired correctly then this won't do but, if you have a manual switch on the furnace to run the fan continuously then turn it on and leave it for a day..the AC will still run and you can test the theory..If it works then have someone rewire the thermostat to run the fan on continuous low/or next to low and automatically go to high speed when the thermostat "call" for cooling. Leave heating mode as is unless the room is too cold in the winter then do the same for heating mode. JUST TRY IT..DOESN'T COST MUCH TOO TRY

IF YOU JUST PUT THE THERMOSTAT TO MANUAL ON THEN JUST THE FAN WILL RUN...DON'T DO THIS.

I have a bedroom sort of like that with a canvas awning over the window. I bought the house that way. How much to put a mature shade tree there? Check craigslist.

Is it hot at night or just the day? One of those little split units will probably cost $1500 to 2000 installed if you get a cheap one. Unless you have bushes there - people can see the little condensor unit outside.

It's not that bad at night. It's just a little too warm during the day. I figured the condenser unit would be the best bet; however, yes, finding one at a good price is almost an impossibility. I'm not exactly rich lol

So, it's been a while. Anything new? Did you get your problem resolved?
Would be nice to know.

Unfortunately, nothing new yet. However, my brother, an AC specialist, recommended that I purchase a dehumidifier to help cool the room.

Personally, I don't think that makes sense. Every forum I have read states that dehumidifiers increase the btu heat in the room.

And, every time I read up on portable AC units, I get so frustrated because every single unit has complainers about leaking units. Not one unit was perfect. I can't risk a leaking unit.

I love dehumidifiers but they do not cool. Anyone used those portable evaporative air coolers? It is not a portable AC with the venting hose. I am not sure if they work.

Evaporative coolers pump water in the air, if I'm not mistaken. Definitely not something you want done.

"Cooling" is only part of a comfortable home. You must also remove moisture if you live in a humid environment, and that is equally as important as removing heat. A house at 78 degs and 80% humidity would NOT be comfortable (think cold and clammy), but a house at 78 degs and 40% humidity would most likely be very comfortable.

Evaporative cooling is used for areas where there is low humidity, and in those areas it works well (think desert conditions - very hot, but very low humidity - like Arizona or New Mexico).

...to just install a portable air conditioner. Nothing to install outside the home (to be stolen and sold for scrap metal). If you could only place the exhaust and intake hoses in your window securely.

In your case, I would make an exception and even go with a single hose unit. They are cheaper and you would be drawing the (colder) air from the rest of your home.

Let us know what you decide...
