Air Conditioner Making Noise

A frequent problem which homeowners experience is their air conditioner making noise, but this problem often has a simple solution.

The high pitched sounds which people often hear coming from their AC unit happens when there is an insufficient amount of air flowing through the return vents, which may be happening due to a variety of issues.

A dirty filter is often seen as the main culprit behind an air conditioner making noise. There may be a blockage in the return vents, the dampers may be closed, or there simply may be too many doors closed in your home.

This high pitched noise is emitted when there isn’t enough air received by the blower which results in an increase in pressure and the noise of your air conditioner system becomes louder. Hearing these sounds should indicate to you that there is something wrong with your HVAC system which needs to be fixed sooner than later or else it may become costlier to repair in the future. With a lowered flow of air, the system also has to work harder to cool your home. This will obviously result in an increase on your bills and can ruin your system in the long run.

How to Solve the Problem

Solving the problem all starts with figuring out what the issue is in the first place. The expertise of a trained DeMark Home Ontario HVAC technician may be necessary to determine the problem and provide you with the best possible solution.

Dirty Air Filters

As previously stated, dirty air filters are often the main culprit to an air conditioner making noise. It’s expected that as an air filter does its job it becomes jammed with dirt and dust. The solution to this is simple, just change your old air filter to a new one. An air filter should be changed every three months.

Closed Dampers

Checking around the home to make sure that none of the dampers are closed will easily stop the problem from persisting if this was the cause for the noise.

Too many closed doors

Leaving more doors open will ensure that the system has enough air and will make for better air flow throughout the home which could put an end to your air conditioner making noise.

Blocked supply or return vents

This could be as simple as furniture being in front of the vents or the vents being dusty. It should be noted that even if a room isn’t in use, you should still ensure that the vents aren’t being blocked as it can cause problems to the whole system.
