Tips for selecting, purchasing, and installing a quiet home A/C. In shopping for a window A/C unit, the first step is to determine how powerful a unit you will need, as expressed in British thermal units per hour, or "BTU." from the Association of Home Appliance Manufacturers can help you figure out the appropriate BTU size air conditioner for your room(s). Following are some suggested quiet window air conditioners that are highly rated for low noise, and that also rate well for quality and efficiency.

These were selected based on published reports of independent product testing and on hundreds of consumer reviews posted to a variety of websites.

Since proper installation is essential for quiet operation, it may not function as quietly as it is designed to if the installation is not carried out correctly according to the instructions. The premium Friedrich Kühl series replaces the QuietMaster line of products. They come at a significantly higher price than other brands for the same cooling capacity.

A mini-split system does require that a hole be constructed through an outer wall, for a pipe to connect the indoor and outdoor components.

This is normally done by a professional. (For this reason, a split system is not usually a feasible option for renters.) "EER" is the Energy Efficiency Ratio, which is calculated as the cooling capacity divided by the power used. The higher the EER, the more efficient the appliance. When comparing two models, a difference of 1 EER point represents about a 10% difference in energy costs to run them for a given period of time.
