You listen to the sounds of your AC more than you probably realize, so you’ll notice when your unit starts to sound off. Besides the usual hum or powering on sounds your air conditioner makes, you shouldn’t be hearing loud AC sounds or any other noises. Unusual sounds nearly always indicate a repair or assessment is needed to ensure your system is running safely and efficiently.
Climate Magic’s team of certified HVAC technicians are well versed in the range of sounds that AC units make. We want you to know which sounds can mean you need professional help from our friendly team’s AC repair services.
1. AC Is Buzzing
Buzzing sounds in your AC unit usually point to electrical issues. There are many electrical components that play roles inside your AC unit, and any electrical malfunctions can pose risk of electrocution or shock. Some of the pieces that you might hear buzzing in your unit are:
- Fan motor
- Contactor relay switch
- Loose wires
2. AC Is Hissing
The presence of hissing usually indicates that air is escaping a tube it’s not supposed to. Oftentimes, this tube is where the refrigerant flows through. A refrigerant leak can be both dangerous and expensive to repair, so it’s best to trust licensed professionals with this AC repair.
3. AC Is Squealing
A squealing noise can point to a worn out blower belt, which is an easy fix for an HVAC contractor. However, squealing can also be a symptom of high internal pressure. If your compressor’s pressure sensor is broken, the pressure inside can rise to dangerous levels. It’s important to shut down your AC system until a technician can confirm the unit is safe to use again.
4. AC Is Rattling, Clanking Or Thumping
These abrupt and solid sounds indicate that a physical piece of equipment is broken or loose inside the unit. This component could be as small as a nut or bolt, or it could be a fan blade. Either way, it’s best to shut down the unit until the piece is found and repaired to avoid any further damage.
5. AC Is Clicking
While your AC may make small clicking sounds when it turns on or off, consistent clicking noises during a cooling cycle are not normal. Your relay or an electrical control could be malfunctioning, and a professional can help you find out. You may waste time and money trying to find the source of the sound yourself, but a specialist will make quick work of the repair!
