What’s Making My AC So Noisy in Lewes, DE?

While there may be a subtle sound when the air conditioning system in your Lewes, DE home runs, noise should be minimal. Banging or clanging sounds are a cause for concern. Understanding what’s making your AC equipment noisy can help you decide when it’s time to seek professional help.

Loose Connections and Equipment

Sometimes, screws, bolts, connectors and panels can come loose over time. This can cause rattling or loud sounds while your air conditioner is running. One of our HVAC technicians can tighten loose connections during a maintenance appointment.

Debris in the Outdoor Condenser

Most central air conditioners have an outdoor condenser that connects to equipment inside your home. You may notice loud sounds during operation if debris like sticks, leaves and grass are stuck in your outdoor condenser. Keep the area surrounding your AC clear of any debris.

Old Motor Bearings

An AC motor draws fresh air from the outside to circulate it evenly throughout the house. However, over time the motor’s bearings may become old and cause squeaking, grinding or rattling noises. Schedule routine maintenance so one of our professionals can diagnose problems early and take action to fix them.

Leaking or Low Levels of Refrigerant

You may hear a buzzing sound coming from your AC if refrigerant lines are leaking and levels are low. This also leads to equipment strain as your AC works harder to achieve your set temperature. Our technicians can top off refrigerant levels and check refrigerant lines to ensure there are no leaks.

Problems With System Airflow

There may be a ductwork problem that is impeding the normal flow of air through your system. Whistling and hissing sounds coming from the ductwork may be signs of damage or obstructions.
