Why is important to do regular maintenance on your Air Conditioning Unit?

Regular maintenance for an air conditioner is important. Helps energy efficiency, cuts down electricity bill, and unit’s longevity. This includes  like changing or cleaning air filters, cleaning coils, checking refrigerant levels, and inspecting electrical components. HVAC maintenance services emphasize the importance of annual professional checkups, which should be scheduled before the season begins to change. 

1. Air Filter Maintenance:
  • Frequency:

    Change or clean air filters every 1-3 months

  • Importance:

  • A clogged filter restricts airflow, making the system work harder, increasing energy consumption, and potentially leading to overheating. 

  • How to:

    Follow manufacturer’s instructions for filter replacement or cleaning.   

2. Coil Cleaning:

  • Gently clean the coils with a soft brush or specialized coil cleaner. Be careful not to damage the fins.  

  • Condenser Coils:

    You can also use a garden hose to spray down the outdoor unit, especially the condenser coils.  

3. Refrigerant Levels:
  • Frequency: Ideally, have a professional check refrigerant levels annually.
  • Importance: Low refrigerant levels indicate a leak and can significantly reduce cooling efficiency.
  • Note: Some experts advise against checking refrigerant levels unless there are signs of a leak, as every time the system is gauged, a small amount of refrigerant is lost. 
4. Condensate Drain Line Maintenance:
  • Frequency: Check and clear the condensate drain line regularly, especially at the start of the cooling season. 
     
  • Importance: A clogged drain line can cause water damage and reduce system efficiency. 
     
  • How to: Pour distilled white vinegar into the drain line to prevent clogs and flush with water.  
5. Electrical Connections:
  • Frequency:
    Have a professional inspect and tighten electrical connections during annual maintenance.
  • Importance:

    Loose or corroded connections can cause safety hazards and reduce performance.  

6. Professional Maintenance:
  • Frequency: Schedule annual maintenance with a qualified HVAC technician.
  • Importance: A professional can perform a thorough inspection, identify potential issues, and ensure your system is running at peak performance. 
7. Other Important Tasks:
  • Keep the outdoor unit clear of debris: Remove leaves, grass, and other obstructions that can hinder airflow. 
     
  • Ensure the unit is level: A level unit ensures proper drainage and operation. 
     
  • Lubricate moving parts: Have a technician lubricate fan motors and other moving parts as needed. 
     
  • Check thermostat settings: Ensure your thermostat is functioning correctly and set to your desired temperature. 
     
  • Inspect ductwork and vents: Look for leaks, blockages, or signs of mold, and seal any leaks.
