DIY AC Troubleshooting Tips Before Calling a Pro
When your AC breaks down, the natural instinct is to call a pro to check for trouble or repair. However, knowing the basic DIY and troubleshooting tips for AC units could end up saving you lots of money. Remember that diagnostic charges from HVAC technicians can be expensive since they specialize in these services. Before you pick up the phone, learn these basic troubleshooting tips first because the issue could involve an easy fix you can do yourself!
Common DIY AC Troubleshooting Tips
Brush up on these DIY AC troubleshooting tips in time for the hot summers in Louisiana so you can confidently navigate minor issues without calling a pro.
1. Air Isn’t Blowing
A common AC issue is when the air isn’t blowing, so it isn’t cooling your home as it should be.
Before calling the pros, there are a few troubleshooting tips to try first. Initially, you may want to check if the thermostat temperature is set correctly. Ideally, it should be a few degrees lower than the room temperature for it to cool enough. Another thing to check is if the thermometer is set to “cool.”
If you’ve tried these remedies and the air in your AC isn’t blowing, you should check if the air filter is dirty. If that’s the case, the dirt could block the airflow from the unit. Clean it or change it and see if it fixes the problem.
The last thing you’d want to check is the power supply, and make sure that the power is on for the outdoor compressor and indoor air handler.
2. Freezing Air Conditioner
Do you notice ice forming on your AC unit? There are many ways to fix this problem on your own without calling for help.
The most common culprit for a freezing AC unit is a dirty air filter. When there is too much dirt on the filter, it blocks airflow and causes the system to freeze.
If you’ve cleaned or replaced the air filter and the issue persists, consider checking the coils for excessive dirt. A low refrigerant charge is another potential cause.
3. Air Isn’t Cool
Let’s say you fixed the issue mentioned in number one. You managed to get the air blowing from the AC unit, but it’s not blowing cool air like it’s supposed to.
A lack of cool air from the AC could be due to various reasons, including a refrigerant leak. If this is the case, you’d need a professional technician to come in and check the system for replacement.
But before you do that, check the air filter first. If it’s dirty, it’s time to clean or change it. Too much dirt can prevent cool air from circulating from the unit and into the room.
Another area to check is the outdoor compressor unit. You must ensure it isn’t blocked as it can also prevent your unit from releasing cool air. And finally, check if the outdoor fan is working. If not, you’ll definitely have to call a professional.
4. AC Cycling On/Off
It’s bothersome when the AC unit is cycling on and off, especially during summer when you need it to run continuously to keep your home cool.
Again, a simple air filter check is needed. If the air filter is too dirty, it will cause the system to work harder to generate cool air for the room.
You should also check to ensure that there is no air register blowing directly into the thermostat.
If none of these troubleshooting steps fix the problem, look into getting a professional for help because you might need to have the refrigerant level checked. Or it could be that you have the wrong sized unit for the room size.
5. Water Pooling in the Indoor Unit
If you notice water pooling around the AC unit, do not ignore the problem because it can lead to water damage.
The first thing you should check is the condensate drain line. If this is clogged, it can cause your AC unit to shut down or not cool your home properly. Use a wet/dry vacuum to get rid of any blockage.
It’s also important to have your AC unit regularly checked and cleaned to eliminate any debris that might block the drain line and cause such problems.
General AC Troubleshooting Steps
No matter the issue with your AC unit, you can follow these troubleshooting steps as most minor issues can be easily remedied if you take these steps.
Step 1: Check the Power Supply
Test the power supply of the AC by looking at other electronic devices at home. If there is a large-scale power outage, it could be the issue. If not, check the circuit breakers or the outdoor unit to ensure they have not been switched off.
Step 2: Check the Thermostat
Aside from the power source, the thermostat is another area to check if you encounter common AC problems. Check if the settings are correct.
Step 3: Check the Vents
Check the vent if the AC is running but it isn’t cooling your home. Any blockage to the vents can be the reason for your AC problems.
Step 4: Check the Air Filter
Most AC problems can be fixed when you clean or change the air filter. It’s an inexpensive fix so make sure to look into this before calling a pro or other major diagnosis.
Step 5: Check the Condenser Unit
The condenser unit is the outdoor component of the AC. It is made up of vents that are designed to protect the sensitive coils, but can have blockages that inhibit the airflow.
When to Call a Professional
Knowing how to tackle DIY troubleshooting is an important skill to possess as it can save you from potentially thousands on repairs. However, it’s crucial to acknowledge that there are certain aspects of your AC unit repair that require expert eyes and knowledge.
If you’ve tried the basic troubleshooting suggested on these common AC problems and the issue persists, it’s time to call an HVAC technician. These professionals can step in and diagnose the problem with your AC unit using their skills and specialist tools.
A lack of adequate air conditioning can make your home uncomfortable during the summer months in Louisiana. It could also be a health risk as it can significantly lower the indoor air quality of your home. Therefore, do not postpone calling an HVAC professional to check your AC unit so those issues can be repaired promptly.
