HVAC system is a very complex machine and it consists of different parts. If these parts have any problem, your air conditioning unit will show some signs including noise coming from your HVAC system. However, this isn’t uncommon for an air conditioning unit to make noises. In this article, I’ll give a few reasons behind your loud air conditioner problem.
Why Is My Air Conditioner Loud? Is It Normal?
As I mentioned above that the air conditioner is a very complex system, and it’s normal to hear noises while it’s running. Generally, you’ll hear humming sounds coming from your system. However, if you hear abnormally loud noise such as hissing noise or rattling noise coming from your AC, there is a high chance that your air conditioning unit has an issue and it need repairs.
Why Is My Air Conditioning So Loud? – 5 Reasons Why
1. Refrigerant Leak Causing Loud AC Problem
Refrigerant is an important component of your AC unit. It absorbs the heat from your space and releases it to the outside compressor unit of your HVAC unit. But when you have a leak in your refrigerant, you’ll start to hear hissing noises coming from your AC unit. Apart from this, you’ll face few signs such as you’ll notice warm air coming from your AC. Besides, your HVAC unit will have frequent turn on and offs. As a result, your monthly cooling bills will go up.
To solve this problem, you must call your nearby HVAC professional and repair the leaks of your HVAC unit.
2. Dirty HVAC Filter Making Your Air Conditioner Too Loud
The main function of an HVAC air filter is to block outdoor microparticles from entering your space. But when it’s dirty, it cannot block outdoor particles and as a result, dirt and debris start to enter your home and air conditioning units. But dirt and debris are very harmful to your AC unit. When this dirt and debris accumulate in the air conditioners, it starts to make rattling noises. That’s why you’ll have to make sure that you change your HVAC air filter regularly and do regular HVAC maintenance checkups to keep your AC unit from heavy repairs.
3. Loose Parts and Fan Blades Making Your Question “Why Air Conditioner is Too Loud”
Malfunctioned fan blades and parts could be the reasons behind your noisy air conditioner issues. As you all know that the HVAC system is made of numerous parts. If any of these parts get loose, your AC may produce abnormal sound. Again, your outdoor compressor has a fan in it. If the fan of the compressor gets misaligned, it’ll start to produce abnormal sound and will make your system noisy.
To prevent these issues from happening, you’ll have to do regular system maintenance checkups. As soon as you notice any sign of noisy AC, you should call your nearby HVAC professional and take help from them.
4. Compressor Failure Making You Ask “Why is My AC So Loud?”
Hissing Noise Coming from Outside
