During the scorching summers, having a reliable air conditioning system is essential to keep your home cool and comfortable. However, AC issues can arise unexpectedly, affecting your comfort and efficiency.
Here are some common AC problems and insights into what you can do as a homeowner to address these issues before calling for professional HVAC service.
AC Isn’t Cooling Properly
When your AC isn’t cooling your home as it should, several factors could be at play, including:
- Dirty or clogged filters: Check and clean or replace air filters regularly to ensure proper airflow.
- Refrigerant leaks: Low refrigerant levels can impact cooling. If you suspect a leak, consult a professional HVAC technician.
- Thermostat issues: Incorrect thermostat settings can result in inadequate cooling. Check your thermostat batteries and settings to ensure it’s on.
- Blocked air vents: Ensure all air vents are open and unblocked for optimal air distribution.
If simple troubleshooting doesn’t improve cooling, it’s best to seek professional help to accurately diagnose and address the issue.
The AC Unit Is Leaking Water
When an AC unit leaks, it’s important to identify whether the leak is water condensate or refrigerant. Refrigerant leaks leave brightly colored stains compared to water. If the leak is refrigerant, shut down the unit and contact an HVAC professional immediately.
In many cases, a drain line leak results from a simple clog. Regularly cleaning and maintaining condensate drain lines can prevent clogs and leaks. For complex leaks, it’s best to consult a professional.
The AC Fan Isn’t Working
If your AC fan isn’t working, there could be several causes, including:
- Electrical issues: Check electrical connections, fuses, and circuit breakers.
- Debris buildup: Clean dust and debris from fan blades and motor to ensure proper function.
- Fan motor problems: If the motor is faulty, it may need replacement.
If checking these doesn’t get the fan working again, it may need to be replaced. Call a professional for a proper assessment.
There Are Strange Noises From the AC
Unusual noises from the system can indicate underlying issues. Rattling, buzzing, or squealing can result from loose or damaged components within the system. You can use a flashlight to investigate whether something is loose, and sometimes the solution is as simple as tightening screws and bolts to minimize vibrations and noises.
Sometimes, a worn belt will cause squealing sounds. Motor bearing issues may result in grinding noises. If these noises are what you’re hearing, or your efforts make no improvement, call a professional for accurate diagnosis and repairs.
The System Is Short-Cycling
Short-cycling is when your AC unit turns on and off repeatedly without finishing a full cooling cycle. If an AC short cycles for an extended period, integral parts like the compressor get damaged.
Faulty thermostats or clogged air filters can cause short-cycling. It can also happen if the AC is too strong for your home.
If your unit is short-cycling:
- Clean and check air filters and vents: Make sure there’s nothing obstructing airflow.
- Inspect your thermostat settings: Ensure it’s functioning properly. If you’re still having trouble, consult a qualified HVAC technician to address other possible issues.
