9 Warning Signs That You Need an Air Conditioner Repair

Has my air conditioner always been this loud? Is that smell… normal? 

If you’re asking yourself these types of questions, there’s probably something wrong with your unit. That problem will just keep getting worse if you ignore it. But how can you tell if there’s actually something wrong or if you’re just overreacting?

It’s always better to be safe than sorry. We’ve put together this guide to help you recognize warning signs from your air condition system and to show you when you should call air conditioning repair in Las Vegas. 

Keep reading below for some helpful tips!

1. Your AC Unit Is Getting Old 

Most air conditioners only last about 12 to 17 years (depending on the type of unit and how well you’ve maintained it, maybe even shorter than that). If your unit is reaching the 10 to 12-year mark, it might be time to schedule a maintenance appointment to make sure it’s in good condition. In some cases, replacing the unit might be more affordable at this point than carrying out any needed repairs. 

2. The Airflow Is Weak 

Take a walk through your home and hold your hand in front of the air vents. Does the airflow feel weak? There might be a clog in the filter, or the motor might be damaged. 

Try cleaning the filter first, but if that doesn’t fix the problem, you may need to call in a professional to replace the motor. 

3. The Vents Blow Warm Air 

The air coming out of your air conditioner should never be warm. If it is, there might be something wrong with the compressor. 

Start by checking the thermostat to make sure it is on the right setting. If your thermostat is old, that could also be the cause of the problem. Replace it with a new one and see if that cools down the air. 

If you still feel warm air, you’ll need to have a professional HVAC technician find and fix the issue. Trying to do this yourself can be complicated, and without the right tools, you might cause more damage. 

4. You Can Smell Bad Odors Coming From the Vents 

Does the air coming from your vents smell musty? That might mean you have mold growing in your air ducts. Living with mold can be dangerous, so you should clean it out right away. 

If the scent smells more like a burning odor, turn off your unit immediately. This is usually a sign of electrical trouble, and ignoring it could, in severe cases, lead to a fire. 

5. The Unit Has Sprung a Leak 

You should never find pools of water around your air conditioning unit. A leaking air conditioner could point to a number of issues, including: 

  • Frozen coils 
  • Dirty filter 
  • Clogged drain line 
  • Damaged drain pan 
  • Low refrigerant levels 

If you spot a leak, you should call air conditioning and heating services as soon as possible. Putting off the repair will only make the leak worse and give the moisture more time to absorb into your floors and walls. This can then lead to mold growth, which can make you and your family members sick. 

6. Your Energy Bill Has Gone Up 

An air conditioning unit that is old or damaged requires more energy to keep the house cool. If you notice a spike in your energy bill and can’t find a reason for it, the culprit is likely your air conditioner. Having a professional take a look at your system will help you pinpoint the exact problem so you can get the monthly costs down again. 

7. The House Doesn’t Cool Evenly 

When you run your air conditioner, have you noticed that some of the rooms in your home cool down quickly while others stay warm? There might be a clog in the ductwork or a buildup of debris on some of your vents. Cleaning the vents may fix the problem, but if the issue is deep in the system, you might need some professional help. 

8. You Hear Weird Sounds 

It’s normal to hear some noise as the air conditioning unit starts up and shuts down. It’s not normal to hear loud, unusual sounds while the system is running. 

For example, a rattling sound might mean there is a loose part bouncing around inside the unit. A squealing sound could mean your fan belt needs to be replaced. Clicking is a warning sign of electrical trouble. 

Does the noise sound like a high-pitched whistle?

Turn off your unit! This could mean there’s a build-up of high pressure inside your unit, which can be extremely dangerous. Call an emergency air condition service right away.

9. The System Goes Through Too Many Cycles 

Your air conditioner will likely turn on more frequently during the peak of summer heat, but it shouldn’t be running constantly. If your system never seems to turn off, it may be having trouble cooling the air that passes through the unit. A professional HVAC technician can find the source of the issue and let you know what to do next.
