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. This is usually due to a malfunctioning component that requires repair or from 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 blog post, we will cover the primary reasons your AC unit is not cooling and what you can do to troubleshoot the issue.

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, which 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.

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. If you’re more comfortable with a professional handling your AC unit, schedule our comprehensive AC maintenance in Cleveland, OH. We’ll replace the air filters, along with checking and servicing all other system components.

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.

Unfortunately, a refrigerant leak is not a DIY fix. You should immediately contact BNK Heating & Cooling to diagnose and fix the problem professionally.

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, causing 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.
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 ensure all other air conditioning system components function correctly.

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, leading to reduced cooling. In some cases, it may even signal the system to turn on and off at inappropriate times, leading to an overworked unit that cannot keep up with the cooling demands.

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.
