Common AC Problems You Shouldn’t Ignore

As the summer months approach so does the need for reliable air conditioning. Unfortunately, when AC units get older or are not properly maintained, they can start to suffer from a range of issues that can impact their performance and efficiency.  It is important to be aware of common problems with your AC unit so you know what signs to look out for and how best to address them before they lead to bigger issues in the future. Here are some common AC problems you should never ignore.

1. Unusual Noises: 

An AC unit that produces loud, strange noises is likely trying to tell you something. High-pitched squealing or grinding noises can indicate worn-out belts or bearings that need to be replaced. If you hear any unusual sounds coming from your air conditioner, it’s best to call in a professional for an inspection right away. Also, always be aware of any strange odors coming from the AC unit as this could indicate a more serious underlying problem. For example, a burning smell could point to an electrical issue or overheating compressor.

2. Bad smell:

In addition to odd noises, bad odors coming from your AC unit are also a sign of an underlying problem. If you find yourself asking the question” Why Does My Air Conditioner Smell?” then the answer is musty smells could indicate mold or mildew growth in the system due to clogged air filters or poor airflow. If you smell smoke or chemicals, this indicates a potential electrical issue with the wiring within the unit and it’s best to call in a professional right away. Also, be sure to check your air filters for dirt and debris buildup as this can also cause unpleasant smells. 

3. Low Airflow/Poor Cooling: 

If you’ve noticed that your AC isn’t cooling as efficiently as it used to, this could be a sign of a dirty air filter or malfunctioning compressor. Both of these issues need to be inspected and addressed by an HVAC technician to restore optimal performance and efficiency. Additionally, clogged ducts can also limit airflow and reduce the effectiveness of your AC system — so make sure they are regularly cleaned and maintained. Also, be sure to check for any issues within the thermostat as this could be causing improper cooling. 

4. High Energy Bills: 

A sudden spike in your energy bills could indicate that something isn’t quite right with your AC system. An improperly functioning unit often needs to run longer in order to reach the desired temperature settings, which leads to higher energy costs. If you’re noticing a noticeable increase in your electricity bills, it’s best to call a professional for an inspection and possibly a tune-up to restore the system back to its optimal performance. This also means it’s important to have regular maintenance checks done — even if your AC unit seems to be running just fine. For example, checking the air filters and refrigerant levels can ensure that your unit is running as it should. 

5. Low Refrigerant Levels: 

When refrigerant levels are low in an AC unit, it will prevent it from cooling effectively, leading to higher energy costs and unnecessary wear and tear on the system. Low levels of refrigerant could be caused by a leak, which will need to be identified and fixed right away. If you notice your AC unit is not cooling as much as it should, this is one issue that should never be ignored — especially if your energy bills are increasing rapidly or you hear hissing sounds coming from the unit. Also, be aware of any frost buildup on the coils as this could also point to a refrigerant issue. 

6. Leaks: 

Leaks near your AC unit can indicate a major problem such as a refrigerant leak or pipe that needs to be replaced. If you notice any signs of leaking, make sure to call in an HVAC technician for further inspection and repair. It’s also important to keep an eye out for any standing water around the unit as this could point to a faulty drain line or clogged condensate pump. Both of these issues will need to be addressed right away in order to prevent future problems with your air conditioner. 

Low Refrigerant Levels

By learning about common AC problems and keeping an eye out for warning signs, you can ensure that your system is running efficiently and effectively all year round. Ignoring these issues can lead to more costly repairs and replacements, so it’s best to address these problems as soon as possible. If you have any questions or concerns about your AC system, don’t hesitate to get in touch with a professional HVAC technician for the best advice and repair services.
