5 Common AC Noises & What They Mean

Hatch Websites • June 28, 2023


When the sound of your AC changes, it means that something inside the unit has also changed. Many noises not only indicate that you need repairs but tell you what kind you need. Listen for these five common noises from your air conditioner.


What Sounds Might Come From Your AC?

1. Squealing

Your air conditioner’s belt squeals when it slips, which can happen when the belt is loose or worn out. Replacing it should stop the sound. The unit may also shriek when the pressure inside is higher than it should be, which happens when a pressure sensor is broken. If this happens, turn off the unit to prevent damage until you can get a technician to look at it.


2. Hissing

A long, continuous hissing sound usually means gas is escaping from a pressurized area. This might mean you have a refrigerant leak. Refrigerant is the substance that absorbs heat from your indoor air to cool interior spaces. However, it is toxic, so get a leak fixed as quickly as possible.


3. Banging, Rattling, Slapping, & Grinding

All these noises usually mean there’s a loose part or a foreign object inside your AC. It might be moved around by your fan or pump or might be getting in the way of moving parts. A specific description of the noise can help your HVAC contractor identify the cause.


4. Buzzing & Humming

A low hum sometimes happens when the flowing air runs over loose components and makes them vibrate. However, the more serious potential cause is an electrical issue, such as loose wiring. If this noise is new, turn off the AC until it’s checked out.


5. Clicking

You should expect a quiet click or two when your unit starts up and shuts down. However, it shouldn’t click while it’s running. Clicks in the middle of a cycle can mean faulty electronic controls, which can damage or wear out other https://www.alpinehcservices.com/cooling-services components as they activate incorrectly.

Choosing the right heating system can make a big difference in comfort and energy costs. For homeowners in Wayne, Holmes, and Ashland counties, Ohio, the most common options include natural gas furnaces, propane furnaces, and electric heating systems. But which option makes the most sense for your home? Natural Gas Heating: Efficient and Affordable Natural gas furnaces are a popular choice throughout Northeast Ohio. Modern high-efficiency furnaces can achieve 95% AFUE or higher, delivering reliable warmth during cold Ohio winters. For homes with access to natural gas, it's often one of the most cost-effective heating options. Propane Heating: Great for Rural Ohio Homes Many homeowners in rural Holmes, Wayne, and Ashland counties rely on propane because natural gas lines aren't available. Propane furnaces provide dependable heat during freezing temperatures. While propane can cost more than natural gas, high-efficiency equipment can help keep heating expenses under control. Electric Heating and Heat Pumps: A Modern Alternative Electric heat pumps have improved significantly in recent years. Unlike traditional electric furnaces, heat pumps transfer heat rather than generate it, making them much more energy-efficient. Modern cold-climate heat pumps can work even when temperatures drop below freezing. Some homeowners also choose dual-fuel heating systems, combining a heat pump with a gas furnace for efficient heating throughout the winter. Which Heating System Is Best for Your Ohio Home? The best heating system depends on fuel availability, energy prices, your home's insulation, and your budget. Whether you live in Wooster, Millersburg, Ashland, or the surrounding communities, choosing the right equipment can improve comfort and help control heating costs. At Alpine Heating, Cooling, Plumbing & Refrigeration, we help homeowners throughout Wayne, Holmes, and Ashland counties find reliable, energy-efficient heating solutions.
