Air Conditioner Not Cooling? Here’s What You Should Troubleshoot

 

Summer is here, and with it comes the heat! For most of us, air conditioning is an essential part of staying cool during the sweltering summer months. However, if your air conditioner is just not producing any cool air, it can be a frustrating and uncomfortable experience.

Understanding why the air conditioner is not cooling is crucial for maintaining comfort in your home. This is usually due to a malfunctioning component that requires repair or a lack of maintenance. BNK Heating & Cooling is here to help you with reliable and effective AC repairs in Cleveland, OH, and all nearby areas.

In this post, we will cover the primary reasons why the air conditioner is not cooling and what you can do to troubleshoot the issue. Regular maintenance and timely repairs are key to ensuring your air conditioner functions efficiently throughout the summer.

Why Your Air Conditioner is Not Cooling

Dirty Air Filter

A dirty and clogged air filter is one of the most common reasons for an AC unit not cooling. Over time, your air filter collects dust, dirt, and other debris. These elements can obstruct airflow and reduce the efficiency of your AC unit. If this happens, your AC unit will struggle to cool your home and you may notice reduced airflow from your vents. The reduced airflow makes it difficult for the system to circulate cool air. This may lead to uneven cooling and increased energy consumption.

Luckily, this problem is easy to solve. Replace your air filter with a new one. We recommend changing your air filter every one to three months, depending on the type of filter and your usage. Keeping a clean air filter not only improves airflow but also enhances indoor air quality to make your home more comfortable.

If you’re more comfortable with a professional handling your AC unit, schedule our AC maintenance in Cleveland, OH. We’ll replace the air filters, along with checking and servicing all other system components. Regular maintenance allows your system to operate at peak efficiency and helps prevent future issues.

Refrigerant Leak

Another common reason for an AC unit not cooling is a refrigerant leak. Refrigerant is a vital component of your AC system and is responsible for cooling the air circulating throughout your home. If your AC unit has a refrigerant leak, it cannot cool your home effectively.

You may also notice ice buildup on your evaporator coils, a hissing sound from your AC unit, or warm air blowing from your vents. Low refrigerant levels can also cause the compressor to overheat and fail which may lead to costly repairs.

Unfortunately, a refrigerant leak is not a DIY fix. You should immediately contact BNK Heating & Cooling to diagnose and fix the problem professionally. Our technicians will locate and repair the leak, recharge the refrigerant, and guarantee your system runs smoothly. Addressing refrigerant leaks promptly can prevent further damage and keep your AC operating efficiently.

Dirty Condenser Coils

Your AC unit’s condenser coils are responsible for releasing the heat that is absorbed by the refrigerant. If these coils are dirty or obstructed, they cannot release heat effectively. This can cause your AC unit to struggle to cool your home. You may notice reduced airflow from your vents, warm air blowing, or your AC unit running constantly. Dirty condenser coils force the system to work harder. This increases energy consumption and reduces the overall lifespan of the unit.

To solve this problem, you will need to clean your condenser coils. You can do this by turning off your AC unit, removing debris around your outdoor unit, and gently cleaning the coils with a soft brush or cloth. If this doesn’t work, schedule your AC repair service with our professionals in Cleveland, OH to find the underlying problem and make sure all other air conditioning system components function correctly. Our technicians have the tools and expertise to clean and service the coils thoroughly, ensuring your AC runs efficiently.

Faulty Thermostat

A malfunctioning thermostat can also cause your AC unit to underperform. If the thermostat is not working correctly, it may not signal your AC unit to turn on and off as required. This can lead to reduced cooling. In some cases, it may even signal the system to turn on and off at inappropriate times which can result in an overworked unit that cannot keep up with the cooling demands. Incorrect thermostat settings can also cause the system to cycle on and off frequently, which can wear out components and reduce efficiency.

To solve this issue, you can check if the batteries need to be replaced, clean the thermostat, check the wiring, and try recalibrating it. If none work, it’s time to call our professionals who will recommend the best solution. We can assess the thermostat and suggest upgrades if necessary. This includes installing a programmable or smart thermostat to enhance your system’s efficiency.

Blocked or Leaky Ducts

Your air conditioner relies on a network of ducts to distribute cool air throughout your home. If these ducts are blocked or leaky, the cool air may not reach its intended destination. Blockages can occur due to dust, debris, or even pests, while leaks can result from gaps or cracks in the ductwork. When ducts are compromised, your AC system has to work harder to maintain the desired temperature. Over time, this leads to increased energy usage and uneven cooling.

Inspecting and maintaining your ductwork is essential for efficient cooling. If you suspect that your ducts are blocked or leaking, professional inspection and cleaning can help. Our team at BNK Heating & Cooling can thoroughly inspect your duct system, identify any issues, and provide necessary repairs or cleaning. Properly sealed and maintained ducts enhance the performance of your AC system and guarantee consistent cooling throughout your home.

Electrical Issues

Electrical problems can also prevent your air conditioner from cooling properly. Faulty wiring, a tripped circuit breaker, or a blown fuse can disrupt the electrical supply to your AC unit, causing it to malfunction. Electrical issues can also pose safety hazards if not addressed promptly. Problems such as the risk of fire or electric shock may arise due to not solving these issues.

If you suspect an electrical issue with your AC unit, it’s important to seek professional help immediately. Our technicians at BNK Heating & Cooling are trained to safely handle electrical problems and can diagnose and repair any issues with your system’s wiring or components. Making sure that your AC unit’s electrical system is in good condition is vital for its safe and efficient operation.

Frozen Evaporator Coils

Frozen evaporator coils can also cause your air conditioner to stop cooling effectively. The evaporator coils are responsible for absorbing heat from the air in your home. When they freeze, they cannot perform this function. This can lead to warm air blowing from your vents. Frozen coils can result from restricted airflow, low refrigerant levels, or a malfunctioning blower fan.

To address frozen evaporator coils, it’s essential to identify and resolve the underlying cause. Turn off your AC unit and allow the coils to thaw. Check for issues such as dirty air filters, refrigerant leaks, or blocked airflow that could be causing the coils to freeze. If the problem persists, contact us for professional assistance. Our technicians can diagnose the cause of the frozen coils and provide the necessary repairs to restore your system’s cooling performance.
