7 Warning Signs Of Air Conditioning Problems

As warmer weather approaches, one of the first things on everyone’s mind is how to beat the heat and stay cool. Whether prepping your home for the summer season or ensuring everything stays in working order, it’s important to pay attention to any potential warning signs of air conditioning problems. After all, no one wants their AC unit to give out in the middle of a scorching day. To help you get through this topic, we’ll go over seven warning signs that could indicate your air conditioner might need some extra care.

Here are seven warning signs that your air conditioning unit may be having problems:

1. Strange Noises Coming From The Unit

You know it’s time to take your air conditioner a little more seriously when you start hearing weird noises coming from the unit. If your AC makes grinding, hissing, or rattling sounds, it may be trying to tell you something. Don’t wait until it’s too late; get it checked out quickly, so you don’t have to worry about a sudden and expensive breakdown in the future.

2. Warm Air Coming From The Unit

If your AC is blowing warm air, don’t wait until it’s too late. It could be a sign of a serious issue that requires the attention of an experienced technician. Refrigerant leaks and issues with the compressor are common culprits. Luckily, professional help is available for this common air con breakdown issue

3. High Energy Bills

Have you been hit with unusually high energy bills lately? It could be an indication that your air conditioner is not running as it should be, and there are many possible explanations for this. You may need to call a technician to check the system, clean or change filters, or look at how often you’re using the unit. In any case, paying attention to your energy bills can help you pinpoint when something isn’t quite right. Then, you have it taken care of before more serious and costly damage is done. 

4. Insufficient Cooling

When it’s hot and humid outside, you want your air conditioner to be keeping up with the temperature. If it feels like your AC is not turning on or you are having difficulty cooling down your home, something may be wrong. It could be a sign of an inefficient system that needs to be serviced or replaced.

5. Water Leaks

Water leaks aren’t something to be taken lightly when it comes to your air conditioner. Detecting a water leak is the first step to preventing major damage and costly repairs. If you notice any sort of wet spot around your air conditioner, it’s best to investigate further. However, don’t wait too long – frequently, these leaks can be linked to an issue with the condensate line or drain pan. It’s always best to address these issues before they become worse. Otherwise, you could find yourself needing more than a simple repair – maybe even replacing the entire system.

6. Ice On The Coils

If you need a blast of cold air and your air conditioner isn’t doing its job, it could be because ice has formed on the coils. This could mean either low refrigerant levels or airflow issues in your unit. So it’s important to take a closer look at this issue so you don’t have to sweat it out during warmer days. Getting the issue addressed quickly by a qualified technician is key since the ice can lead to further damage if left unchecked. So beat the heat with quick action – check those coils and get your air conditioner up and running again.

7. Musty Odours Coming From the Unit

It’s never pleasant to come home and get hit with a musty odour from your air conditioner. While that can sometimes be the result of something that was left in the unit, it can also be a sign of a more serious problem – mould or mildew growth. That’s why paying attention is important if you notice those musty odours coming your way. Then take action immediately to address it before it becomes an even bigger issue.


Your air conditioner is an important part of your home, and making sure it’s in tip-top shape is essential for a comfortable living environment. Pay attention to the warning signs mentioned above, and if you see any of them, call a professional as soon as possible. Don’t let a small issue become a costly repair; take care of your AC, and it’ll take care of you. Happy cooling!
