AC Not Blowing Cold Air? Try These DIY Tips Before Calling Jonas Energy for Repair

Published August 24, 2024

Experiencing an air conditioner failure on a hot summer day can be one of the most frustrating moments for any homeowner. Whether you’re located in Lake County or the surrounding areas, the professional team at Jonas Energy is here to help you get your cooling system back up and running. Our skilled HVAC technicians are well-versed in all types of air conditioning systems and are ready to diagnose and fix any issues quickly, efficiently, and affordably.

Evaluating Your Air Conditioner: Step-by-Step Troubleshooting

When your air conditioner stops blowing cold air, the first step is to perform a thorough evaluation of the system. Understanding the root cause of the issue is not just important for the immediate fix but also crucial for preventing future breakdowns that could lead to more expensive repairs. Here’s a detailed look at some of the most common issues that might be affecting your air conditioner:

  • Power Issues: Ensure the AC is properly plugged in, and check for any issues with the electrical panel, such as a tripped breaker or blown fuse.
  • Clogged Filter: A clogged filter can significantly reduce airflow, potentially causing the motor to overheat. Regularly clean or replace your filters to maintain optimal performance.
  • Clogged Drain: Over time, the drainpipe in your AC unit may become clogged with debris. If water backs up, the unit may shut down as a fail-safe to prevent damage.
  • Condensate Airflow Switch: If your unit has a safety switch that trips when the drainpipe is clogged, you’ll need to clean the pipe before resetting the switch.
  • Dirty Air Compressor: Dirt and debris can accumulate around your outdoor air compressor, impacting its efficiency. Regular cleaning, especially before and after winter, is vital.
  • Ice Buildup: Ice can form in your AC due to various factors, such as dirty filters or low refrigerant levels. After cleaning, run the unit with the fan only to melt the ice.
  • Low Refrigerant Levels: Low refrigerant often indicates a leak. This issue requires professional attention to repair and recharge your system.
  • Thermostat Issues: Ensure the thermostat is set to the correct temperature and that all connections and batteries are in good condition.

Power Issues

Believe it or not, one of the first things to check is whether your air conditioner is receiving power. It’s possible that the unit has been accidentally unplugged or that the outlet or circuit breaker has tripped. If your AC isn’t receiving power, it won’t be able to function at all. Start by ensuring that the unit is plugged in properly, and then check your electrical panel for any tripped breakers or blown fuses. If everything appears to be in order and the unit still won’t turn on, it’s time to call in a professional. Electrical issues can be complex and dangerous, and our HVAC technicians at Jonas Energy are trained to handle them safely.

Clogged Filter

A clogged air filter is a common culprit when it comes to reduced airflow or a complete lack of cold air. Over time, dust, dirt, and other debris can accumulate on the filter, blocking the flow of air and forcing your AC to work harder. This not only reduces the efficiency of the system but can also lead to overheating and potential damage. Regular maintenance, including checking and replacing the air filter, is essential for keeping your AC running smoothly. If you notice that your AC is struggling to cool your home, the first thing you should do is check the filter. If it’s dirty, replace it with a clean one and see if that resolves the issue. If the problem persists, there may be other underlying issues at play.

Clogged Drain

Your air conditioner not only cools your home but also removes excess moisture from the air. This moisture is typically drained away through a condensate drain line. However, over time, this drain line can become clogged with dirt, algae, or other debris. When the drain is clogged, the water backs up into the unit, triggering a safety switch that shuts down the system to prevent water damage. If you suspect that a clogged drain is causing your AC to stop blowing cold air, you can try to clear it yourself by using a mild bleach solution. However, if you’re unsure or uncomfortable doing this, it’s best to call a professional HVAC technician from Jonas Energy to handle the job.

Condensate Airflow Switch

Some air conditioning units come equipped with a condensate airflow switch, a safety feature designed to shut down the system if water backs up into the drain pan. This switch prevents water from overflowing and causing damage to your home. If this switch is triggered, you’ll need to clean the condensate drain line and reset the switch before your AC will start working again. If you’re unfamiliar with this process, our technicians at Jonas Energy can take care of it for you, ensuring that your system is back up and running in no time.

Dirty Air Compressor

The air compressor is one of the most vital components of your air conditioning system, responsible for circulating refrigerant and keeping your home cool. Because the compressor is usually located outside, it’s exposed to the elements and can become dirty or clogged with debris such as leaves, grass, and dirt. When this happens, the compressor has to work harder to cool your home, which can lead to overheating and system failure. Regularly cleaning the area around your compressor and scheduling professional maintenance with Jonas Energy can help keep your system running efficiently. Our technicians are experienced in thoroughly cleaning and inspecting compressors, ensuring they function properly and prolong the life of your AC system.

Ice Buildup

Ice buildup inside your air conditioner is a sign that something is wrong. There are several potential causes of ice accumulation, including dirty filters, low refrigerant levels, or restricted airflow. When ice forms on the coils of your AC, it can prevent the system from cooling your home effectively. To address this issue, start by checking the air filter and replacing it if it’s dirty. You can also try running the system with just the fan on to help melt the ice. However, if the ice buildup is severe or the AC still isn’t blowing cold air after the ice has melted, it’s time to call in the professionals. Low refrigerant levels often indicate a leak, which requires expert attention to repair.

Low Refrigerant Levels

Refrigerant is the substance that cools the air inside your air conditioner. Unlike other components, refrigerant doesn’t deplete over time. If your AC is low on refrigerant, it’s likely due to a leak somewhere in the system. Leaks can occur in various parts of the AC, such as the coils or refrigerant lines, and they need to be repaired by a certified HVAC technician. At Jonas Energy, our technicians have the tools and expertise to locate and repair refrigerant leaks, recharge the system, and get your AC back to cooling your home efficiently.

Thermostat Issues

Sometimes, the issue with your air conditioning may not be the unit itself but the thermostat that controls it. If the thermostat isn’t set correctly or if there are issues with its wiring, your AC may not function as it should. Start by ensuring that the thermostat is set to the correct temperature and that it’s switched to the cooling mode. If the AC doesn’t turn on or blow cold air, check the thermostat’s wiring to make sure everything is connected properly. If the thermostat uses batteries, replace them with fresh ones to see if that resolves the issue. If you’re still having problems, it may be time to replace the thermostat or have it inspected by a professional.
