With the scorching summer heat upon us, maintaining your air conditioning system is crucial for ensuring a comfortable living environment. While professional HVAC services from reputable companies like Bradley Heating & Air Conditioning are always recommended for major repairs or installations, there are several DIY tips you can follow to keep your AC unit running smoothly.

Clean or Replace Air Filters

  • Regularly cleaning or replacing air filters is one of the easiest and most effective ways to maintain your air conditioner’s efficiency.
  • Clogged filters restrict airflow, causing the system to work harder and increasing energy consumption.
  • Check your manufacturer’s recommendations for filter replacement intervals, typically every 1-3 months.

Clear Condensate Drain Lines

  1. Locate the condensate drain line, which is typically a plastic pipe near the indoor unit.
  2. Use a wet/dry vacuum or pour a mixture of warm water and vinegar down the line to clear any blockages.
  3. Ensure the drain line is properly sloped and connected to allow proper drainage.

Clean Outdoor Unit

  • Regularly removing debris, such as leaves, twigs, and dirt, from the outdoor unit helps maintain proper airflow and prevents overheating.
  • Carefully use a soft-bristle brush or a garden hose (without a high-pressure nozzle) to gently clean the unit’s fins and coils.
  • Trim back any vegetation growing too close to the outdoor unit to ensure proper ventilation.

Inspect and Insulate Ductwork

Check your ductwork for any leaks or gaps, which can significantly reduce the system’s efficiency. Seal any holes or gaps with duct sealant or foil tape, and consider insulating exposed ductwork to prevent energy loss.


By following these simple DIY tips, you can help extend the lifespan of your air conditioning system, improve its efficiency, and potentially save money on energy bills. However, remember that for more complex issues or professional installations, it’s always best to consult with a reputable HVAC company like Bradley Heating & Air Conditioning to ensure the safety and proper functioning of your system.
