Many malfunctions are accompanied by noise when the air conditioner is turned on. The reasons for the noise when the air conditioner is turned on must be found out as soon as possible and damage must be prevented in time.
Where does the power-up noise come from?
If noise comes from the indoor unit when turned on, clogged air filters may be the source. Poor equipment maintenance most often leads to malfunctions. If the filters are clogged with dust, they should be washed and dried, then the hiss may disappear.
Sometimes the noise when the air conditioner is turned on appears due to the clogging of the outdoor unit. The radiator is full of dust, fluff from trees, dry foliage. If there is a lot of dirt, the outdoor unit may make a lot of noise.
Sometimes gurgling from the freon line indicates a freon leak. Although some air conditioners gurgle even in perfect condition.
What are the causes of air conditioner noise?
Noise when turning on the air conditioner appears for one of the following reasons:
- vibration of the outdoor unit;
- close location of the outdoor unit and pipes;
- breakage of fan blades;
- violation of the rules for installing the air conditioner.
The hissing from the indoor unit of the air conditioner when turned on may indicate a clogged freon line, the outflow of refrigerant, a decrease in the cross section when the pipe is kinked. Sometimes these sounds are characteristic of a re-installed used air conditioner.
Eliminating air conditioner noise
Actions in case of noise from the air conditioner:
- check the condition of the outdoor unit, if it is clogged, you should at least vacuum the radiator, and it is better to order a professional cleaning;
- look into the indoor unit, if the filters are dirty - they need to be washed;
- check the condition of the bolted bearing (it could crumble or loosened fasteners).
You can eliminate the noise of an air conditioner by identifying its cause.
For example, if the problem is compressor vibration, reduce it. Sometimes you even have to change the unit itself. This will significantly reduce the noise level of the air conditioner in decibels.
The same goes for the fan blades. The impeller is replaced with a whole one.
The owners of the air conditioner will face a more serious problem if it makes noise due to an illiterate installation, this should be corrected by the master who performed the installation.
We'll have to completely reinstall the equipment.
If the air conditioner makes a noise after being turned on, but does not start, the problem may be a low voltage or the control board.
