What Does a Failing Home AC Sound Like?

With summer’s temperatures getting hotter with each passing day, now is not the ideal time for your air conditioning unit to go out. Unfortunately, though, whether it is due to extended use or age, air conditioners do fail. If you are able to spot the signs of a system going bad ahead of time, you can get the necessary air conditioning repair in Kalamazoo, MI before you and your family are left without service this summer. Here are a few of the most notable indicators that your air conditioner might be on its way to failing.

Unusual noises

Some of the most common causes of AC failure start with the compressor. It is the compressor that provides the cool air to your home by converting the refrigerant into gas and back again. As your compressor wears down over time, it will become more and more difficult to start your system. This strain is usually marked by a rattling noise when you turn your air conditioner on, which is a sign that the relay switch that starts the compressor might be declining. Since this is an electrical issue, it is safest to call a professional to come and take a look.

Besides the sounds of the air flowing into your home through the vents and the outdoor unit running, your air conditioner should be operating relatively quietly. If you hear any strange sounds, either as you turn on your system or while it is running, they are usually a strong indicator that something is wrong.


In addition to signaling that your AC could eventually stop working altogether, a leak could pose a potential risk to those in your home. That is why it so important to seek professional help at the first sign of any leaking, as refrigerant that leaks from your compressor could cause nausea, eye irritation, headaches and other health problems.

Problems with temperature and airflow

While it might not be as noticeable as a leak or loud noise, weakened airflow is also a symptom of a failing air compressor. As your compressor wanes, so too will the air that it is able to generate, and as a result less air will blow out of your vents. Alternatively, the airflow coming from your system might be fine, but you may have noticed that it is blowing warm air instead of cool air. In either instance, consulting with a professional HVAC contractor to determine the source of the problem is recommended.
