Regular maintenance is the key to a long-lasting, efficient air conditioner. While some tasks require a professional, there is plenty homeowners can do to keep their system in top shape. Use this checklist each cooling season.
What You Can Do Yourself
- Change the air filter every 30 to 90 days during heavy use. This is the most impactful DIY task.
- Clear the outdoor unit of leaves, grass and debris, keeping at least two feet of clearance on all sides.
- Gently rinse the condenser fins with a garden hose to remove dirt, using low pressure.
- Keep vents open and unblocked by furniture, rugs or curtains to maintain airflow.
- Check the condensate drain line for clogs and clear standing water near the indoor unit.
- Test the thermostat and replace its batteries if needed.
What to Leave to a Professional
- Refrigerant checks and recharging, which require certification and specialized tools.
- Electrical inspection of connections, capacitors and contactors.
- Deep coil cleaning of the evaporator and condenser coils.
- Measuring temperature split and verifying the system meets specification.
- Inspecting the blower motor and ductwork for airflow problems.
Timing Your Maintenance
Schedule your professional tune-up in spring, before the cooling season begins. Handle the DIY tasks at the start of summer and check the filter monthly throughout. This rhythm keeps your system ready for New Jersey's hottest days and helps prevent the breakdowns that always seem to strike during a heat wave.
