I'm living in Phoenix, AZ, and my upstairs can get really hot during summer, especially in my daughter's room, which faces west and gets that harsh afternoon sun. The AC unit, located in another room, usually registers 5-6 degrees cooler than her space, so the cooling system doesn't kick in until it's almost unbearable. The house is relatively new (built in 2017) with decent insulation, but I suspect the problem lies mainly with her windows. They are double-pane but standard builder grade, and while we've put up blackout curtains, it's not enough to keep her room cool. I'm looking into exterior sun screens and heard about interior window quilts that could help with heat management. I'd love to hear any suggestions that don't involve replacing the windows or doing major renovations. Thanks for your help!

First, check if your HVAC system is zoned. If it’s not and the door stays closed when your daughter sleeps, that could trap hot air. Also, consider solar screens or awnings for the windows. It's worth double-checking your insulation too; sometimes, it can make a big difference!
Cellular shades could be a cost-effective option to install right next to the glass, which helps with insulation. Running the house fan on and adding a booster fan to the air duct might also improve air circulation without major expenses. Avoid window replacements if possible.
Have you considered a mini-split system or smart vent boosters? They can effectively manage the temperature in individual rooms depending on your setup.
You might want to look into window film or tint. It can really cut down on the heat that comes in through the glass without having to replace the windows.
I appreciate the suggestion, but I don't think it's an airflow issue since there's already a return vent in her room. I'm not really interested in mini-splits either, as they seem too pricey for this situation.
