As temperatures begin to rise in the spring, many homeowners look forward to turning on their air conditioning system for the first time of the year. After months of sitting idle through the winter, however, air conditioners often benefit from a quick check before the cooling season begins. Taking a few simple steps now can help prevent unexpected breakdowns during the hottest days of summer.
- Replace the air filter
One of the most common causes of poor air conditioning performance is a dirty air filter. When filters become clogged with dust and debris, airflow through the system is restricted. This can cause the system to work harder than necessary and may lead to higher energy bills or even frozen coils. Replacing the filter at the start of the cooling season helps keep air moving freely through the system. 1” filters should be changed about once a month during the cooling season.
Wider media filters may last the entire season without a change. - Clear debris around the outdoor unit
Leaves, sticks and other debris often collect around the outdoor condenser unit during the fall and winter. These obstructions can block airflow and reduce efficiency. It is recommended to maintain at least two feet of clear space around the unit and gently remove any debris that may have accumulated. - Check supply and return vents
Furniture, rugs and curtains sometimes end up covering vents without homeowners realizing it. Blocked vents can cause uneven cooling throughout the home and place additional strain on the system. Walking through the house and ensuring vents are open and unobstructed can improve airflow and comfort. - Test the thermostat early
Waiting until the first hot day of the year to test the air conditioner can lead to uncomfortable surprises. Turning the system on briefly during the spring allows time to confirm that the thermostat is working properly and that cool air is flowing through the vents. - Schedule seasonal maintenance
Professional maintenance can help identify small issues before they turn into major repairs. During a typical inspection, a technician will check electrical components, measure refrigerant levels, inspect coils and ensure the system is operating safely and efficiently.
Air conditioning systems often work hardest during the hottest days of the year. Preparing the system before summer arrives can improve efficiency, extend equipment life and help ensure a comfortable home when temperatures climb.
Expert Tip:
Closing too many air vents in unused rooms can actually make an HVAC system less efficient. Modern systems are designed to move a specific amount of air, and restricting airflow can increase strain on the equipment.
