This is a well known and common problem. Tuccillo is quite correct, as well as others. While the current set up is most likely compliant to the Manual J for the home, variables exist.

There is only so much you can do without encountering significant costs. Of course, redesigning the system and adding zones would work, but that is quite costly...especially when you have a new home with a already new system.

Other methods, while less than perfect can also help. Balancing your system by adjusting vents MAY help to an extent, and it costs nothing. Making sure that duct is sized correctly for the room is also a good idea. Also insuring there are no "bellies" or excessive elbowing in the supply duct is also helpful.

Adding insulation there may also help, but understand that in most of these front corner guest bedrooms this area can be difficult to almost impossible to get to or even see. This is why I use a thermal imaging camera.

Personally I think the issue of cooling this room in the summer is more difficult than heating it in the winter, but that is just my opinion. Because windows are always less efficient, how you deal with that window can be a large factor.

Also, personal preferences came into play here. Many folks LIKE a somewhat cooler bedroom. However, if your home faces South or West in the summer and you do not deal with that sometimes huge window, good luck on keeping that room cooler in the summer.

You basically have the situation of three outside walls and a large window in a small square foot room.

I'm told that The Villages policy is that a 5 degree difference between rooms is acceptable. I have seen many times when the difference can exceed that.

Every home is different. Some folks never use this room. Some folks use this room for a craft room or office, and do not sleep there. Some folks use this room only a few times a year for guests, and do not want it to be TOO comfortable, because one typically does not want guests to overstay their welcome. (a bit of humor).

It comes down to how big this problem is perceived by the homeowner and how much they want to spend to make it less of a problem. If the home is under warranty, sometimes the A/C company will come out and adjust ductwork or enlarge it, etc...but there is only so much they can easily do.

Different window treatments can help in some cases, and some folks tint that window or windows, but be careful on voiding the window warranty if you do.

Basically, common actions to make this better is window treatments, adding insulation, upsizing the supply duct, adjusting A/C grills to balance the system somewhat, keeping the door open, using a small heater, etc, etc may help.

Villagetinker, I smiled when I read about your ceramic paint additive. I bought and used this product on the home I built up north, and I too have some of it left While I was not sure how well it worked, I got it for a good price years ago and thought I would try it. I never knew anyone else who had it until now.

I apologize for the long post. Since I was mentioned in an earlier post, I felt compelled to share.
