If you’re unsure when to replace your AC, here’s a quick guide for you. We’ll go over some of the most common signs you need to look out for. While this may seem like an impossible task, you’ll find that it’s quite straightforward.

Signs You Need to Replace Your AC

Lack of Cooling

If your AC isn’t working properly, you’ll notice that your home is hot and humid when the weather is warm outside. You may also notice that your windows are fogging up. If this happens often or if you’ve noticed other signs of trouble (such as low airflow), you should consider calling in professional AC services or replacing your AC unit.

Moisture Buildup

Moisture buildup is a common problem in many homes. Several factors can cause it, but the most common cause is a lack of airflow. Here are some signs that you are experiencing moisture buildup in your AC:

  • You see water stains on the walls or ceiling around your thermostat.
  • The temperature in your home feels warmer than it should be, and the humidity is high.
  • You notice mould growing on walls or the floor near vents or outlets.

If you see any of these signs, it’s time to call an AC professional to check out your system and determine if it needs to be replaced.

Very High Energy Bills

It’s true that air conditioners are expensive to replace, but old units also use a lot of energy. If your air conditioner is older than 10 years or has more than 12,000 hours of use, it might be time to replace it. On average, an air conditioner lasts about 15 years before needing to be replaced.

Loud Noise From the External Unit 

If you hear a loud noise from the external unit of your air conditioner, it’s time to replace the unit. This is because the sound is caused by the expansion and contraction of liquid refrigerant as it passes through your AC’s compressor.

When your unit was new, there was enough pressure in the system to keep liquid refrigerant flowing easily; however, heat and other factors caused the pressure to drop. When this happens, you might notice a loud knocking noise from the external unit and visible moisture leaking from your AC’s drain tube. 

It’s important to note that these symptoms do not mean that your whole system needs replacement; they just mean that one part—the compressor—needs replacing.

Water Leaks Around the AC Unit

When you have a water leak around your air conditioner, it means that you need to replace your AC unit. This is so important because water leaks around your AC unit can cause damage to the coils. 

This will then lead to more problems with the AC unit and possibly other parts of the house. This can also be a safety issue because water leaking out from around the AC unit could create a slippery surface that could cause someone to fall over and get injured.

Conclusion

As the summer approaches, it is important to diagnose your air conditioning systems and make necessary changes. The signs listed above are indications that your system is on its way out and needs replacement. Contact an HVAC professional if you experience any of these issues and schedule a tune-up.
