5 Common AC Noises & What They Mean

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.

Do You Need to Replace Your AC Because of New Refrigerant Rules?

May 20, 2026

If you’ve heard people talking about “new refrigerant rules” for air conditioners and heat pumps, you’re not alone. Homeowners are wondering if their current AC system is suddenly outdated or impossible to repair. The simple answer is no — you do not need to replace your air conditioner just because refrigerant rules have changed. What Changed With HVAC Refrigerants? The HVAC industry is moving away from higher-GWP refrigerants, including R-410A, and toward newer refrigerants with lower environmental impact. Under the EPA’s refrigerant transition rules, many new residential air conditioners and heat pumps manufactured after January 1, 2025 must use lower-GWP refrigerants. Existing systems can still be serviced, and parts used to repair existing systems are not subject to the same restrictions as new equipment. For homeowners, that means your current air conditioner or heat pump does not automatically need replaced. Can My Current AC Still Be Repaired? Yes. If your system uses R-410A, it can still be serviced. The bigger question is whether a repair makes financial sense. As older refrigerants become less common over time, certain repairs — especially refrigerant leak repairs — may become more expensive. That does not mean every older system should be replaced, but it does make the repair-versus-replace decision more important. When Should You Consider Replacing Your AC? You may want to consider replacement if: -Your system is over 10–15 years old -You are facing a major repair -Your AC has a refrigerant leak -Your energy bills keep climbing -Your home has uneven temperatures -Your system uses older equipment that is no longer under warranty If your system is newer, running well, and only needs a minor repair, replacement may not be necessary. Don’t Panic — Get Honest Advice The new refrigerant rules are a real change in the HVAC industry, but they should not be used to scare homeowners into replacing equipment before they need to.
