Updated: May 13

As the summer season approaches, it's important to ensure that your central air system is ready to keep you cool and comfortable during those sweltering Texas months. Proper preparation and maintenance can help maximize the efficiency of your system, extend its lifespan, and prevent unexpected breakdowns.

Tips for Preparing Your Central Air for Summer

Clean and replace air filters. The first step in preparing your central air system for summer is to clean or replace the air filters. Over time, filters accumulate dirt, dust, and debris, which can restrict airflow and reduce the system's efficiency. Clean or replace the filters according to the manufacturer's recommendations, ensuring that the air circulating through your home remains clean and your system operates efficiently.

Inspect and clean the outdoor unit. The outdoor unit of your central air system can become clogged with leaves, dirt, and other debris during the winter months. Before the summer season, inspect the outdoor unit and remove any obstructions. Use a soft brush or vacuum cleaner to gently clean the fins and coils. Ensure that there are at least two feet of clear space around the unit to allow for proper airflow. Keeping the outdoor unit clean and unobstructed enhances the system's performance and prevents potential damage.

Check and clean air vents. Blocked or dirty air vents and registers can hinder airflow and reduce the efficiency of your central air system. Before summer arrives, inspect each vent and register in your home. Remove any obstructions such as furniture, drapes, or rugs that may be blocking the airflow. Vacuum or dust the vents to eliminate dust buildup. Ensure that the vents are fully open and unobstructed to promote proper air circulation throughout your home.

Schedule professional maintenance. Consider scheduling a professional maintenance service for your central air system before the summer season begins. An experienced HVAC technician can perform a comprehensive inspection, clean the components, and identify any potential issues. They will check refrigerant levels, inspect electrical connections, and test the system's overall performance. Regular professional maintenance ensures that your central air system operates efficiently, reduces the risk of breakdowns, and helps identify problems early on.

Test the system and adjust the thermostat. Before the temperatures rise, it's essential to test your central air system to ensure it's functioning correctly. Turn on the system and listen for any unusual noises. Feel the airflow from the vents to ensure it's strong and consistent. Additionally, adjust your thermostat settings to reflect your desired summer temperatures. Consider installing a programmable or smart thermostat that allows you to set schedules and optimize energy usage.

Consider energy-saving upgrades. If your central air system is outdated or inefficient, consider investing in energy-saving upgrades. Upgrading to a higher SEER (Seasonal Energy Efficiency Ratio) rating can significantly improve your system's efficiency and reduce energy consumption. Additionally, installing a zoned system allows you to cool specific areas of your home, saving energy in unoccupied rooms. Consult with an HVAC professional to determine the best upgrades for your home's needs and budget.

The bottom line

Preparing your central air system for summer is crucial for optimal performance and energy efficiency. By following these essential steps, including cleaning and replacing air filters, inspecting and cleaning the outdoor unit, checking and cleaning air vents and registers, scheduling professional maintenance, testing the system, and considering energy-saving upgrades, you can ensure a cool and comfortable home throughout the summer season.
