Imagine this: you’re relaxing at home on a hot summer day, feeling grateful for your trusty air conditioner keeping you nice and cool. But then, you start hearing some weird noises coming from your HVAC system. Uh oh, why is my AC making loud noises?
You don’t have to panic just yet! Those funny noises could actually be trying to tell you something important about what’s going on with your AC. It’s your air conditioner’s way of saying, “Hey, I’ve got a little issue over here that needs some attention!”
The point of an energy-efficient central air conditioning system is to keep your home comfortable while maintaining energy consumption. However, when these systems start making loud noises, it can signal underlying issues needing immediate attention. Understanding these noises and what they mean is key to keeping an efficient and long-lasting AC unit.
AC Making Loud Noises: 8 Common Noises and How to Fix
Banging Noises
If your AC unit is making banging noises, it usually indicates a problem with the compressor. The compressor is the heart of the AC that circulates the refrigerant and maintains pressure within your system. When parts inside the compressor become loose or damaged, they create a banging sound. Ignoring this can lead to severe damage and costly repairs.
The best solution is to turn off your AC and contact a local HVAC technician to inspect and repair the compressor. Don’t wait until the damage worsens.
Screeching Sounds
Screeching sounds are typically a sign of a malfunctioning fan motor. Nine times out of ten, that high-pitched noise is because there are issues with the outdoor condenser fan motor, compressor motor, blower fan motor, damaged bearings, or an impaired fan belt.
Operating your AC with these issues can cause further damage. It is important to turn off your AC immediately and call a HVAC contractor to diagnose and fix the problem. The sooner you address it, the less damage there will be.
Humming Noises
A humming noise from your AC unit is often a sign of a defective contactor relay switch. This AC part controls the flow of electricity to various parts of your air conditioner. Without that working properly, your AC basically your AC won’t start or do its job of cooling your home.
Call a licensed technician to replace the faulty relay switch and restore your system’s functionality.
Buzzing Sounds
Buzzing sounds in your AC unit can be due to several issues. These include loose or unbalanced fan blades, a faulty fan motor, dirty coils, loose components, or a refrigerant leak. These problems can affect your system’s performance and efficiency.
Again, the best plan of attack is to perform a thorough air conditioner tune-up with a licensed technician to address these issues.
Rattling Noises
Rattling noises often come from loose debris in the outdoor unit. In the best-case scenario, removing the debris will solve the problem. However, rattling can also indicate a damaged electrical contractor, requiring prompt attention. Ignoring this issue can lead to electrical failures and more extensive repairs.
A licensed technician can inspect, repair, or replace the damaged electrical contractor to restore your AC’s functionality.
Clicking Sounds
Clicking sounds during cooling cycles are normal. However, you should be wary of continuous clicking, as this may indicate a malfunctioning thermostat. A faulty thermostat can cause fluctuating temperatures and your home not cooling down properly. Maybe you experienced your AC blowing hot air. No fun!
To resolve this issue, call a licensed contractor to replace the thermostat and get your AC back to operating correctly.
Hissing Noises
Hissing noises from your AC unit can be due to an air duct leak, a malfunctioning expansion valve, or an incompatible air filter. These issues can reduce your system’s efficiency and bring your energy consumption to the roof.
This is another case for you to contact the pros for a complete AC inspection and repair to save you some headaches and maintain optimal system performance.
Bubbling Sounds
Bubbling sounds are typically caused by moisture due to a crack, blockage, or hole in the drainage pipe. If you don’t address it right away, you may have to deal with water damage and mold growth.
Inspecting the drainage line and calling a certified technician to replace any damaged components can prevent these issues and keep your AC operating efficiently.
