   – Clean the exterior: Remove dust and debris from the unit’s surfaces.
   – Replace or clean air filters: A study from the Department of Energy (2016) indicates that dirty filters can reduce efficiency by up to 15%.
   – Inspect drainage systems: Ensure that drain pans are clear and that water flows freely to prevent mold growth.

2. Summer:
   – Check refrigerant levels: Low refrigerant affects cooling performance. Regular checks help maintain optimal operation.
   – Clear vents and ducts: Blocked vents can cause poor air circulation. Ensure they are unobstructed by furniture or dust.
   – Conduct a thermostat check: Ensure the thermostat provides accurate readings to prevent excessive energy use.

3. Fall:
   – Seal windows and doors: Use weatherstripping to close any gaps. This maintains indoor temperatures and reduces energy costs.
   – Winterize outdoor units: Cover the unit with a protective cover to shield it from snow and ice. This prolongs its lifespan.
   – Inspect insulation: Proper insulation helps reduce heating demands in winter, leading to lower energy bills.

4. Winter:
   – Keep the area clear: Remove snow and ice from around the outdoor unit to maintain proper airflow.
   – Run the unit periodically: Regular operation during warm winter days can help prevent mechanical issues.
   – Schedule professional maintenance: An HVAC technician can perform a thorough inspection and tune-up to ensure reliable operation when needed.

By implementing these strategies, you can ensure that your unit runs efficiently and reliably throughout the year.
