1. Clean or Replace Air Filters Regularly

  • Clogged air filters restrict airflow, reducing the efficiency of your AC unit and increasing energy consumption.
  • Check and clean or replace your filters every 1-3 months, depending on usage and manufacturer recommendations.
  • Disposable filters should be replaced, while reusable filters can be cleaned with water and a mild detergent.

2. Clear Obstructions Around the Outdoor Unit

  • Ensure there is at least 2 feet of clearance around the outdoor condensing unit to allow proper airflow.
  • Trim back any vegetation or remove debris that may be blocking the unit.
  • Regular clearing helps prevent overheating and ensures efficient operation.

3. Inspect and Clean the Condenser Coils

  • Dirty condenser coils can cause the HVAC system to work harder, leading to higher energy bills and potential breakdowns.
  • Carefully remove any debris or dirt buildup from the coils using a soft brush or a coil cleaning solution.
  • Be cautious and follow safety guidelines when working with electrical components.

4. Check for Proper Thermostat Operation

  • Ensure your thermostat is set to the desired temperature and is functioning correctly.
  • Replace batteries if needed and consider upgrading to a programmable or smart thermostat for better energy efficiency.
  • Proper thermostat operation can prevent unnecessary cycling and save energy.

5. Schedule Professional AC Service and Maintenance

  • While DIY maintenance is helpful, it’s essential to have a professional HVAC technician inspect and service your system annually.
  • Professional maintenance includes tasks like refrigerant level checks, electrical component inspections, and thorough cleaning.
  • Regular professional service can identify and address potential issues before they become major problems.
