Air conditioner noise is a problem that affects a great many people. If your ac unit is creating a lot of noise, this affects not only yourself, but your neighbors as well. Before we get into ways to reduce or block this noise, lets talk about what makes air conditioners so noisy. Generally speaking, the source of AC noise comes down to vibration. The compressor in an ac unit creates a great deal of vibration, and this vibration will create noise at varying intensities, depending on how well the connection points have been insulated within the unit.
Whether you have a central air system with interior ducting or a mini-split system with an outdoor compressor/condenser and an interior evaporator, vibrational noise is going to be an issue. Air-cooled condensers usually consist of a compressor, coil, expansion valve and a fan. The compressor creates high sound pressure waves and these can increase over time as the moving components (motor and valves) start to wear down. This problem is further exacerbated when the insulating pads placed at the connection points begin to wear down as well.
This vibrational noise is not something that can be resolved by making changes to the compressor’s connection points, as the compressor tends to be inaccessibly housed within the unit itself. This leaves isolating the entire AC unit, which we will discuss in the solutions section of this page.
One of the most common complaints about air conditioner noise is that it disrupts sleep. This represents a serious problem given the fact that numerous health issues have been tied to loss of sleep, with some research suggesting a link between nighttime environmental noise exposure and cardiovascular disease. Even low-level noise can have an impact on health due to sleep disturbance.
Excessive air conditioner noise can also lead to legal issues when the air conditioner noise becomes too much for your neighbors to bear. Whether it is a visit from the police or an anonymous noise complaint that results in a fine, these legal problems can all be avoided by applying the right solution to this troublesome noise source.
Given the dangers that air conditioner noise presents to yourself and those around you, coupled with the legal issues that can arise from it, finding a solution that reduces air conditioner noise is extremely important.
