When your AC isn’t cooling your home properly, it can get frustrating, especially during those sweltering hot summer months. Like every appliance in your home, there are some troubleshooting steps that you can work through before you panic and call for professional help for these common AC problems. Chances are that you can determine the cause and potentially resolve the issue on your own, and in case you couldn’t resolve the problem on your own, you can always call a professional. In this blog, we will outline some common reasons why your AC may not be cooling and offer helpful steps to address each situation.
Steps for When Your AC Isn’t Cooling:
- Check the Thermostat Settings: This is the first and easiest step. Verify the thermostat settings. Ensure the thermostat is in cooling mode and that the setting is lower than the temperature of the room. Inadvertently switching the thermostat to “heat” or “fan” mode occasionally can stop the air conditioner from cooling. Give the system some time to respond before making any necessary adjustments to the settings.
- Verify Power Supply: Next, check the power source for your air conditioner. Make sure the AC is correctly plugged in and that the circuit breaker or fuse protecting the appliance is not disturbed. Reset the circuit breaker if it has tripped, then check to see whether the air conditioner begins to cool. Contact a qualified electrician to identify and resolve any electrical issues if the problem doesn’t go away.
- Replace Your Air Filters: Dirty and clogged air filters can significantly restrict airflow and reduce the cooling efficiency of your AC system. Check the air filters and clean or replace them if necessary. Consult the manufacturer’s instructions for guidance on how to properly clean the filters or replace them. This simple step can often resolve cooling issues and improve the overall performance of your AC.
- Inspect and Clean the Condenser Unit: It is located outside and can become dirty or clogged over time. Inspect the unit and clear away any debris, leaves, or vegetation that may be blocking the airflow. Use a garden hose to gently clean the condenser fins and remove any built-up dirt or grime. Ensure that the unit has enough clearance around it for proper airflow. Restricted airflow can cause the AC to work inefficiently or not cool at all.
- Check the Refrigerant Levels: Lower refrigerant levels can stop the AC from cooling properly. However, checking and adding refrigerant is a task best left to a professional HVAC technician. In case you find a refrigerant leak or low levels, it’s recommended to contact a qualified technician to inspect and recharge the refrigerant as needed.
- Examine the Ductwork: Leaky or improperly insulated ductwork can lead to cool air escaping before it reaches the desired areas of your home. Inspect the ductwork for any visible leaks or disconnected sections. Seal any leaks using foil tape or mastic sealant. Additionally, check for any obstructions or blockages in the ductwork that may be hindering airflow. Properly insulated and sealed ductwork is essential for proper cooling.
- Clear Obstructions from Vents: Make sure that all supply and return vents in the house are clear and unobstructed. Move furniture, curtains, or any other objects that may be blocking the airflow from the vents. This allows for better air circulation and ensures that the cooled air can reach all areas of your home.
- Consider the Outdoor Temperature: In hot climates, extreme outdoor temperatures can put a strain on even a well-functioning AC system. If the outdoor temperature is excessively high, your AC may struggle to cool your home to the desired temperature. Consider using fans or shades to minimize heat gain from sunlight, and close curtains or blinds during the hottest parts of the day.
- Schedule Professional Maintenance: Regular professional maintenance is crucial for the optimal performance of your AC system. If you have tried the above steps and your AC still isn’t cooling properly, it may be time to schedule a maintenance appointment with a skilled HVAC technician. They can inspect your system, identify any underlying issues, and perform necessary repairs or adjustments.
There are a number of measures you may take to investigate and possibly fix the problem when your AC isn’t cooling. The air conditioner is an important addition to your home. If all else fails, it is advised to seek expert help to identify and resolve any complicated problems. It’s important to bear in mind that routine maintenance and timely attention to cooling issues can assist keep your AC operating effectively and guarantee a comfortable interior atmosphere.
