How to Find a Quiet Air Conditioner

You can find a quiet air conditioner in any size or configuration, from large, powerful split-system central air units to window-mounted air conditioning models to easily relocated rolling portables. Take note of these suggestions on how to find and install a quiet air conditioner that will meet your unique cooling needs.

Step 1: Determine the Capacity of the Air Conditioning System You Need

If you are just going to cool down a bedroom for comfortable sleep, an air conditioner of up to 10,000 BTU (British Thermal Units) will suffice. These are available in window units and portable units that pump out warm air through flexible pipes placed in a window or into a wall duct exhausted to the outdoors. To cool an entire house, choose a split air conditioning system with the hardware outside and the ducts and delivery vents inside. Find a model that can deliver up to 24,000 BTU of cooling energy.

Step 2: Comparison Shop

Ask friends and neighbors who use air conditioners for recommendations. Visit the websites of national reputable manufacturers, and focus your search on the selection of air conditioners whose best quality is their silent or very quiet operation.

Examine the construction of air conditioners in the store. If they make any kind of excess noise in ideal display conditions, they will when you take them home and install them, too.

Ask a salesperson to remove the front panel so you can study the type and amount of insulation inside the air conditioner. A thick layer of insulation will help the condenser chill the air more effectively while quieting sound at the same time. Also look at the size of the intake vent section on the front panel. If it fills almost the whole front panel, you will hear more noise from inside the air conditioner. An intake vent grid less than half the size of the front panel will take in the correct amount of air from the room, and help in ridding noises from the air conditioner's normal operation.

Step 3: Install the Air Conditioner Properly Once You Get it Home

Install window-mounted air conditioners solidly and correctly leveled on the window sill and inside the window frame. Ensure the window frame is thoroughly sealed to prevent the whistling sound of air coming in around the unit. Place portable air conditioners as far from the window or external vent as you can, while preventing obstruction of room traffic. Secure the flexible duct tubes into the near window or the exhaust vent so they do not jar loose at slight vibrations. Stabilize the ends of these duct tubes to avert flapping and clicking of the end supports, as air rushes out from the air conditioner.

If you have chosen a split air conditioner system, seek professional assistance to get the ducts and components installed and functioning effectively. Place the large compressor and condenser housing under a deck or in a sheltered area outdoors out of direct winds, so those sounds do not travel into your home.
