Many malfunctions are accompanied by noise when the air conditioner is turned on. The causes of noise when turning on the air conditioner must be found out as soon as possible and in time to prevent breakage.
Where does the noise come from when turned on?
The noise of the air conditioner may come from the outdoor, indoor modules or freonrace.
If noise occurs from the indoor unit when turned on, clogged air filters may be the source. Poor equipment care most often leads to malfunctions. If the filters are clogged with dust, they should be washed and dried, then hissing can disappear.
Sometimes the noise when turning on the air conditioner appears due to the clogging of the outdoor unit. The radiator is full of dust, fluff of trees, dry foliage. If there is a lot of dirt, the outdoor unit can make a lot of noise.
Sometimes gurgling from a freon pipeline indicates a leak of freon. Although some air conditioners even in perfect condition gurgle.
What are the causes of air conditioning noise?
The noise when the air conditioner is turned on appears for one of the following reasons:
- vibration of the outdoor unit;
- close location of the outdoor unit and pipes;
- breakdown of the fan blades;
- violation of the rules for installing the air conditioner.
Hissing from the air conditioner's indoor unit when turned on may indicate clogging of the freon route, refrigerant outflow, and a decrease in cross-section when the pipe breaks. Sometimes, such sounds are characteristic of a reused used air conditioner.
Air conditioner noise reduction
Actions for noise from the air conditioner:
- check the condition of the outdoor unit, if it is clogged, at least vacuum the radiator, and it is better to order professional cleaning;
- look into the indoor unit, if the filters are dirty - they need to be washed;
- check the condition of the bearing, bolted (it could crumble or the mounts loose).
You can eliminate the noise of the air conditioner by identifying its cause.
For example, if the problem is compressor vibration, you should 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 fan blades. The impeller is replaced by the whole.
The owners of the air conditioner will face a more serious problem, if it makes noise due to an illiterate installation, this should be fixed by the master who made the installation.
Have to completely reinstall the equipment.
If after turning on the air conditioner is noisy, but does not start, the problem may be in the low voltage of the network or the control board.
