Diagnosing Strange HVAC Noises in Manhattan Apartments: When to Call for Repairs in 2024

Strange HVAC Noises in Your Manhattan Apartment? Here’s What They Mean and When to Call for Help

Living in Manhattan means dealing with the constant hum of city life, but when your apartment’s HVAC system starts making unusual sounds, it’s time to pay attention. These sounds aren’t just a spooky tale; they’re often signs that something might be wrong with your heating and cooling equipment. Understanding what these noises mean can save you from costly repairs and uncomfortable living conditions in 2024.

Common HVAC Noises and Their Meanings

Since our HVAC system can make many different sounds, and since many of us take their continual operation for granted (we shouldn’t, though), it would be a good idea for us—owners and renters alike—to know more about this topic. Here are the most common sounds you might hear:

Banging and Clanking Sounds

When your quiet home is suddenly disrupted by banging or clanking sounds coming from your air conditioning unit, it’s a signal that not everything is right within your system. These noises typically indicate that there are loose or unbalanced parts lurking within your AC. Banging from the compressor is a sign of loose parts inside the compressor, such as a piston pin or connector rod, as well as parts on the outside of the compressor. Call a professional to fix the banging noise right away, or further damage may be caused as your air conditioning unit continues to run.

Clicking Noises

If you’ve ever heard a fast-clicking noise from your thermostat when the air conditioner first starts up and shuts down, this sound is normal. When a clicking noise repeats throughout a cooling cycle, it’s a sign of trouble. If your unit is clicking constantly or more than at start up and shut down, it could mean there are electrical control issues. The clicking might be caused by a defective relay or a problem with the thermostat.

Hissing and Squealing

If your unit hisses, especially when it isn’t running, it may mean you have a leaky refrigerant line, an internal valve leak, or the compressor’s pressure is too high. In any case, you need to call your HVAC technician as soon as possible. Don’t turn the unit back on until it has been looked at and/or repaired. Refrigerant leaks can be quite dangerous to people, animals, and the environment.

Buzzing and Humming

If there is persistent buzzing coming from your outside HVAC unit, it is a good indicator of a refrigerant leak or that your unit is freezing up from too much usage. Buzzing could be an electrical problem or even a refrigerant leak. Refrigerants are harmful for the environment. Prevent a noisy HVAC by calling a professional who can properly check where the leak is coming from, repair it and then refill the refrigerant.

Manhattan-Specific HVAC Challenges

One of the most challenging NYC noise complaints in the city are those from exterior building heating, ventilation, and air conditioning equipment. HVAC equipment involves generators and rotating machinery that produce incessant noise that can disturb nearby locations. Because HVACs in New York are typically located on roofs of buildings or on the sides of buildings, it is usually a severe nuisance to adjacent buildings in close proximity, interfering with residents’ sleep, work, and relaxation.

I know most of Midtown is steam generators fed by ConEd’s steam pipes. Lower manhattan has a lot of steam boilers in the buildings with some hot water boilers peppered in there. This unique infrastructure means Manhattan apartments often deal with water hammer issues and steam-related noises that require specialized expertise.

HVAC equipment involves rotating machinery and air moving devices which generate noise to nearby noise sensitive locations or through a building’s interior. This is particularly true if the HVAC equipment is centrally located inside a building or on its roof as opposed to being in its basement.

When to Call for Professional Repairs

If your unit is normally quiet and suddenly starts emitting sounds, you should call an HVAC professional right away. If you wait too long to address any new sounds, it could result in damage to your system, which as previously stated, will cost you more money to fix.

You should immediately contact a professional if you hear:

The moment that you hear a whistling or squealing coming from your system, the first thing you need to do is shut off your unit immediately. The reason for this is to prevent any of the parts that could be causing the noise from breaking. After you have turned off the HVAC unit, seek professional help, taking note of what type of sound you are hearing and any thoughts you have about what may be causing it.
