All air conditioners, to some degree, are designed to minimize the sound they make. However, many home owners find the noise levels objectionable and greater than anticipated, after the installation is complete. The location of a condensing unit can significantly influence the perceived noise level. When you double the distance between you and the air conditioner, you decrease the sound by 5 dB, which is about ¼ as loud. While manufacturers do guarantee the sound levels of their equipment they can't guarantee the perceived noise level from patios, windows and bedrooms.

Sound blankets are a popular solution for reducing compressor noise, from air conditioners or heat pumps. They reduce compressor noise by 5 dB or more -- a substantial 40% + reduction.

The sound blanket fits inside the cabinet and wraps around the compressor -- the noisiest component of an air conditioner or heat pump. The two-piece design allows quick installation in tight cabinets where space is a consideration and where the compressor is close to the coil or the fan. The sound blanket is securely attached with hook and loop closures, which are durable and make installation quick and efficient. The use of a sound blanket will not adversely affect the compressor's performance. In fact, sound blankets are a conventional form of noise reduction for air conditioners and heat pumps and most manufacturers use them frequently to reduce noise levels.
