Your home’s air conditioning system is one of the priciest parts of your house to run and maintain. The hissing sound that accompanies this machine indicates a problem within the system. You may have noticed a small hissing sound when your AC was first installed, but it was easy to disregard as it was isolated to the start-up phase. If you’ve been running your AC without any problems for a few days and are now noticing this sound, it’s important to address its cause before it worsens. Here are common problems that cause hissing in your AC.
1. AC Not Cycling Properly
This is a common cause of noise in your AC system. If the cycle isn’t complete and your AC turns on and off repeatedly, this could cause a problem with the compressor. If you’re unsure what it sounds like when your AC is cycling properly, listen for a humming noise that increases and decreases in volume as it starts up, turns off, and then starts up again. If you’re hearing a hissing sound instead, you can be sure it needs to be serviced. Air Conditioning Service can help you determine the specific cause of your noise problem and fix it at a fair price.
2. Air Filter Needs To Be Changed
If your AC sounds like it’s struggling to start up and is humming, the most likely cause is the filter. If your AC’s filter hasn’t been changed, it may be clogged with dust and debris. This can cause a reduction in airflow, which may make the compressor work harder to produce the desired cooling effect. If you have pets or children in the house, you will probably need to change the filter more often as it will be dirtier more quickly.
3. Refrigerant Levels Are Low
If the AC doesn’t have enough refrigerant in it, it may not be able to operate at the desired temperature. If this is the problem, you may notice a loud hissing sound when your AC first kicks on, and then it will eventually stop. You may also notice that your AC produces unwanted heat instead of cold air.
4. Dirty Coils
The coils in your AC condenser will become dirty over time, making your AC louder than normal. Blocked or dirty condenser coils can cause the compressor to work harder than it needs to and, in turn, produce more heat and create a louder sound. Dirt out of the condenser coils will eventually work through the entire system and impact your heating operation. If you notice a hissing sound coming from your AC unit, use a coil cleaner to eliminate any dust or debris causing the noise.
5. Compressor Is Completely Burnt Out
If your AC compressor is completely burnt out, it will be completely unrecognizable and produce a constant low-pitched hum. This could be a sign that the compressor has been working too hard and is doing more than it should, causing a loud noise in the system. The compressor can also become contaminated with moisture or oil residue due to its excessive use, which can cause it to overheat and burn out. It is important to contact AC Service experts if you notice a loud noise coming from your AC when it’s running. They will be able to visually inspect the compressor and determine if it needs to be replaced or can be repaired.
For the best possible results with your AC, it is important to be proactive and have regular maintenance performed by a qualified technician.
