Mid-Size A/C Units: 9000-12000 BTU Window Air Conditioners
Window air conditioners in the 9,000 to 12,000 BTU range are ideal for midsize rooms such as larger bedrooms and midium size living areas to provide cool relief in the warmer months. These units have a wide variety of features and offer everything from basic dial controls all the way up to fully digital with wireless capability.
Depending on how often you plan to use the unit, and of course the size of your space, will probably determine to the kind of features you’ll want. If you know you only use the unit at night, then a basic model with on/off controls will more than likely be sufficient. But if you would like the air conditioner to cycle on and off as the ambient temperature in your space changes, or if you would like the AC to turn on at a specific time, then you’ll definitely want to go with a model with a programmable timer and digital thermostat.
