Loud air conditioners ruin the tranquility of your home. From humming and rattling to high-pitched whines, these sounds can become a source of aggravation. They interfere with sleep, conversation, and relaxation. A noisy AC can also grind productivity to a halt if you work from home. The good news is that most noise issues have easy fixes.
Understand Where the Noises Come From
Before eliminating the noise problem, you must know where it comes from. Most AC noise comes from the compressor fan in the outdoor unit. Some air conditioners make more noise when starting up, while others become louder when cycling down.
Your air conditioner can grow louder over time due to worn parts. Minor issues like loose screws or more significant problems like clogged components can impact noise levels. Each noise has a different solution.
You can play the detective! Take note of when the noises occur, how long they last, and the type of sound. Is it a constant hum or a clicking noise? This approach will help you narrow down the causes.
Choose a Quieter Unit
If you are shopping for a new AC, consider the noise ratings. The industry rates noise levels for air conditioners in decibels. Even a minor difference of 10 dB can significantly impact quiet operation.
You should look for air conditioners labeled as quiet or ultra-quiet. Mini-split systems and variable-speed central units typically operate more quietly than other systems. Inverter technology allows them to run at lower speeds, stopping the annoying noise.
Install a Sound Blanket
Compressors are your primary source of AC noise. Installing a sound blanket can significantly reduce noise without impacting AC performance. These covers wrap around the outdoor unit securely and absorb much of the compressor’s sounds for quieter operation.
Sound blankets are especially beneficial for older air conditioners. Although manufacturers did not build older units with noise reduction in mind, sound blankets are an easy and affordable way to reduce loud sounds.
Add Acoustic Barriers
The noise can become more stressful if the outdoor unit sits near a bedroom or patio. Installing an acoustic barrier can help dampen the sound. A fence, wall, or shrubbery can help reduce the sounds that make it into your home or patio. Remember to keep all barriers at least 2 feet away from every side of your outdoor unit.
Use Vibration Pads or Anti-Vibration Mounts
Much of the noise stems from vibrations from the compressor, which can transfer into your home and cause disruptions. You can install isolation pads under the compressor. These pads, made of rubber or neoprene, help absorb the vibrations before they spread. Anti-vibration mounts secure the compressor in place and reduce vibrations.
Tighten or Replace Loose Components
Over time, screws and panels can loosen and cause noise. Even small vibrations can create loud rattling. We can inspect and tighten all components to reduce noise and improve operation.
If panels become damaged or warped, they need replacement. Bent fan blades can lead to wobbling and excess noise. Our technicians can find the sources of your excess AC noise and offer prompt solutions.
Seal Ducts and Insulate Ductwork
For central ACs, noise can come from the ductwork. Noises often mean leaks or poor duct design. Gaps and cracks can allow air to escape, producing whistling or hissing sounds coming from the vents.
We specialize in ductwork solutions. Our team will inspect your ductwork and offer repairs, sealing, or insulation, depending on your needs.
Schedule Professional Maintenance
The quietest air conditioners receive regular maintenance. During an HVAC tune-up, our technicians clean essential components, tighten connections, and check refrigerant levels. These steps and replacing worn parts can reduce the noise your air conditioner makes.
Neglected systems are more likely to operate loudly. Fans may strain to move air, motors wear down, and refrigerant leaks can stress your system. Regular AC tune-ups in West Covina help prevent these problems.
Rethink Your Unit Placement
When planning a new system installation or renovation, consider noise when deciding where to place the outdoor unit. Avoid putting outdoor condensers near bedroom windows or next to patios whenever possible.
