How to Keep Your Air Conditioning Unit Noise Free and Efficient

Did you know that a resident of Boston, MA, filed a complaint against the noise produced by a neighbor's air conditioner? This happened on July 29, 2011, as reported by Newport Daily News.

If you do not want to face a similar fate, read on for some easy servicing tips for your air conditioning unit.

Reasons for a Noisy Air conditioning Unit

A poorly maintained air conditioning unit can make loud noises and interfere with your peaceful daily lives. The following are some of the areas that require regular servicing for the better functioning of your HVAC system:

Duct: As the AC functions, the metal duct tends to expand and contract during air distribution. The noise produced by the air handlers in the duct increases when the unit is not serviced or cleaned for long periods of time.

The condenser fan: Children can sometimes insert materials that may interact with the condenser fan and produce sounds. It is easily reachable by insects and other deterrents also.

Indoor blower: The indoor blower consists of a motor, fan blade and house. If the blade touches the house too often, the air conditioner could make noises. Also, if the motor is not functioning properly, then chances are that it will produce sounds.

Central unit AC: The condensation line produces bubbling sounds if its functioning is restricted.

Air Conditioning Maintenance Check List

Given below are the areas that are serviced when you call for the services of an air conditioning professional:

Cleaning coils: Dirt and grime builds up on the coils, which puts stress on the mechanical parts of your unit. Getting it serviced by a specialist smoothens its functioning and eliminates the unwanted sounds.

Checking refrigerant level: Improper refrigerant levels could force the unit to work harder and lead to unusual sounds and reduced lifespan. The technician can advice you about the right level.

Inspecting drain pan: Clearing the drain of any obstruction is important to ensure that moisture does not collect in the unit.

Checking outdoor and indoor blowers: Older blowers may need the drive belt replaced or inspected for any wear and tear. The indoor blower assembly (fan wheel, motor) may also need to be adjusted for optimal functioning.

Inspect all electrical controls, wiring and connection: This step is performed by the technician to check all hookups for damage or obstructions.

Checking duct for leakage: Air leakage in the duct is the main reason for the malfunctioning of the forced-air AC. Ductwork is inspected and sealed or insulated in the problem areas by the technician to avoid noise and inefficiency.

Running a general system test: The technician checks all the operating functions, checks for odor and unusual noises and measures system pressure for the smooth working of your unit.
