If you notice significantly weaker airflow in certain areas, it may be necessary to adjust the dampers in your ductwork.

Dampers are adjustable plates within the ductwork that control the amount of airflow to specific areas of your home. By partially closing the dampers in rooms that receive too much cooling and opening the dampers in rooms that need more, you can help redistribute the airflow and achieve a more balanced temperature throughout your home.

Adjusting Vents and Registers

Another way to address uneven cooling is by adjusting the vents and registers in your home. Begin by ensuring that all vents and registers are fully open and unobstructed. Ensure that furniture, curtains, or other objects are not blocking the airflow. If necessary, rearrange furniture or remove obstacles to allow for better air circulation.

In rooms that are consistently too cool, you can partially close the vents or use vent deflectors to redirect the airflow away from certain areas. Conversely, if a room is consistently warmer, fully open the vent to maximize airflow. By making these adjustments, you can help regulate the temperature and achieve more even cooling throughout your home.

Cleaning HVAC Components

Over time, dust, dirt, and debris can accumulate on the various components of your HVAC system, including the air filters, coils, and blower. This buildup can restrict airflow and affect the cooling efficiency of your system. Regular cleaning of these components is essential to maintain optimal performance.

Start by inspecting and replacing or cleaning the air filters. Clogged filters can impede airflow and cause uneven cooling. Refer to our article on excessive dust in the home for more information on proper filter maintenance.
