Air conditioner noises mean that there is something wrong with your unit. While the noises might not prevent the air conditioner from running, they are a ticking time bomb and you should address them immediately. According to AC contractors, the air conditioner can produce different sounds that result from different faulty areas. Here are the common sounds:

Rattling AC noises

They are probably the most common noises and come about when the fasteners in the unit are loose. To fix the problem you should check the screws and bolts holding the plates in plates and tighten them. If the noises continue, remove the cover and check the inside of the unit for loose screws. If there are any fix them. If you do this and the noises continue, you should hire an HVAC professional to inspect the unit.

Screeching AC noises

Screeching noises result from a faulty belt or motor that runs the blower. You should inspect the fan belt and if in bad shape replace it. The cool thing is that you can easily replace the belt even if you never replaced it before. If you don’t have the time or aren’t confident in your skills hire an AC replacement professional to help you out. If the noises are coming from the motors, lubricate them. As rule of thumb, use high-quality lubricant.

Whistling sounds in the air conditioner

Whistling sounds result from seals that aren’t working properly. The most affected seals are those along the cracks and duct seams. You should examine the seams and if loose tighten the bolts or screws. It’s common for manufacturers to cover the seals using heat tape. To be on the safe side ensure that seal completely adheres to the duct seams.

Hissing sound in the Air conditioner

When your unit is producing this sound it means that your unit has a catastrophic refrigerant leak that should be addressed by an AC technician. The professional should replace the refrigerant line. Fixing this problem requires the expertise of an experienced professional; therefore, you should only hire the most qualified person.

Animal sounds in the ACs ductwork

It’s possible for birds and small animals to sneak inside the ductwork and get stuck there. You should contact the animal control department in your area and ask them to remove the animals. To prevent the animals from getting there again identify the entry points and close them.

Conclusion

These are some of the AC noises that you need to know about. Getting rid of the noises requires expertise; therefore, ensure that you work with an experienced HVAC company.
