What to Do When Your AC Isn’t Cooling Your Home?

When the summer heat peaks, a malfunctioning air conditioning system can be frustrating and uncomfortable. If your AC isn’t cooling your home as it should, you can take several troubleshooting steps before calling for professional assistance. In this guide, we will provide helpful tips and solutions to address the issue of an AC that isn’t cooling your Atlanta home.

1. Check the Thermostat Settings

Start by checking the thermostat settings. Ensure it is set to “cool” mode and the temperature is lower than the current room temperature. Double-check that the schedule and temperature settings are accurate if the thermostat has a programmable feature. Sometimes, incorrect thermostat settings can cause an AC not to cool properly.

2. Clean or Replace the Air Filters

Clogged or dirty air filters can obstruct airflow, reducing cooling efficiency. Check the air filters in your HVAC system and clean or replace them if necessary. Clean filters allow for better airflow and help the AC system to cool your home more effectively.

3. Inspect and Clean the Condenser Unit

The condenser unit outside your home can accumulate dirt, debris, and vegetation over time. This buildup can restrict airflow and hinder the cooling process. Inspect the condenser unit and remove any obstructions or debris. Gently clean the fins using a soft brush or a vacuum cleaner with a brush attachment. Be careful not to bend the fins during cleaning.

4. Check for Obstructions around Vents and Registers

Blocked or closed vents and registers can disrupt the airflow and prevent proper cooling. Ensure that all vents and registers are open and unobstructed. Move furniture or other objects that may be blocking the airflow. This allows for better air distribution and can help improve cooling performance.

5. Inspect the Outdoor Unit for Issues

Inspect the outdoor unit for any visible signs of damage or malfunctions. Check for bent or damaged fins, signs of refrigerant leaks, or loose electrical connections. If you notice any significant issues, it’s best to contact a professional HVAC technician for further assessment and repairs.

6. Ensure Proper Insulation and Sealing

Inadequate insulation and air leaks can impact the cooling efficiency of your AC system. Check the insulation in your home, especially in the attic and walls, to ensure it is sufficient. Seal any air leaks around windows, doors, and ductwork to prevent cool air from escaping and warm air from entering your home.

7. Schedule Professional Maintenance:

Regular professional maintenance is essential for optimal AC performance. Professional technicians can thoroughly inspect and diagnose the underlying issues, perform necessary repairs or adjustments, and ensure your AC system operates at its best. If your AC isn’t cooling despite troubleshooting efforts, it may be time to schedule a maintenance service with a trusted HVAC provider like Atlanta Heating and Air Solutions.
