Maintaining your air conditioner is essential for optimal performance and efficiency. Regular upkeep not only extends the lifespan of your unit but also helps you save on energy bills and avoid costly repairs. At Anderson Heating and Air, we understand the importance of a well-maintained air conditioner. This ultimate guide will provide Bentonville residents with comprehensive tips on air conditioner maintenance.

Why Air Conditioner Maintenance Matters

Before diving into the maintenance tips, let’s explore why regular air conditioner maintenance is crucial:

  • Improved Efficiency: A well-maintained AC unit operates more efficiently, reducing energy consumption and lowering utility bills.
  • Extended Lifespan: Regular maintenance helps prevent wear and tear, prolonging the life of your air conditioning system.
  • Enhanced Comfort: Proper maintenance ensures your AC delivers consistent cooling, keeping your home comfortable.
  • Better Air Quality: Clean filters and components improve indoor air quality by reducing dust, allergens, and pollutants.
  • Preventing Major Issues: Routine checks can identify potential problems early, preventing costly breakdowns and repairs.

Essential Air Conditioner Maintenance Tips

  1. Replace or Clean Air Filters

One of the most critical maintenance tasks is regularly replacing or cleaning the air filters. Dirty filters can restrict airflow, causing the system to work harder and less efficiently.

  • Frequency: Replace disposable filters every 1-3 months. Clean reusable filters according to the manufacturer’s instructions.
  • Process: Turn off the AC, remove the filter, and either replace it or clean it thoroughly before reinstalling.
  1. Clean the Coils

Both the evaporator and condenser coils play a crucial role in cooling your home. Over time, they can accumulate dirt and debris, reducing their efficiency.

  • Evaporator Coils: Located inside the indoor unit, these coils should be inspected and cleaned annually.
  • Condenser Coils: Found in the outdoor unit, these coils should be cleaned more frequently, especially if the outdoor unit is in a dusty or polluted area.
  1. Check the Condensate Drain

The condensate drain allows moisture to escape from the system. A clogged drain can cause water damage and affect performance.

  • Location: Find the condensate drain line, typically near the indoor unit.
  • Maintenance: Inspect the drain for any blockages and use a wet/dry vacuum or a long brush to clear any obstructions.
  1. Inspect the Thermostat

Ensure your thermostat is functioning correctly and set to the desired temperature. Consider upgrading to a programmable thermostat for better energy management.

  • Settings: Verify that the thermostat is set to “cool” and at the appropriate temperature.
  • Calibration: If the thermostat isn’t accurately reflecting the indoor temperature, consider recalibrating or replacing it.
  1. Clean and Clear the Outdoor Unit

The outdoor unit (condenser) should be free from debris, leaves, and dirt to function correctly.

  • Power Off: Ensure the outdoor unit is powered off before cleaning.
  • Debris Removal: Clear away any leaves, grass, or debris from around the unit.
  • Fin Cleaning: Use a garden hose to gently spray the fins and remove dirt. Avoid using high pressure to prevent damage.
  1. Check Refrigerant Levels

Low refrigerant levels can reduce cooling efficiency and damage your system. If you suspect a refrigerant issue, contact a professional to check and refill the refrigerant.

  1. Inspect Electrical Connections

Loose or damaged electrical connections can affect your AC’s performance and safety. Inspect the connections and tighten any loose ones.

  • Power Off: Ensure the AC is powered off before inspecting.
  • Check Connections: Inspect all electrical connections for signs of wear or damage.
  • Tighten and Repair: Tighten loose connections and replace any damaged wires.
  1. Schedule Professional Maintenance

While many maintenance tasks can be performed by homeowners, scheduling annual professional maintenance is crucial. A qualified technician from Anderson Heating and Air can perform a thorough inspection, identify potential issues, and ensure your system is in optimal condition.

Seasonal Maintenance Tips

To keep your AC in top shape, consider the following seasonal maintenance tips:


  • Pre-Season Check: Schedule a professional inspection to prepare your system for the upcoming cooling season.
  • Filter Replacement: Replace or clean the filters before heavy use begins.


  • Monitor Performance: Keep an eye on your AC’s performance and address any issues immediately.
  • Outdoor Unit: Regularly clear debris from around the outdoor unit.


  • End-of-Season Maintenance: Clean the coils and replace filters after the cooling season.
  • Cover the Outdoor Unit: Consider covering the outdoor unit to protect it from debris during the off-season.


  • Indoor Maintenance: Focus on indoor components and ensure the system is ready for the next cooling season.
  • Store Window Units: If you use window units, clean and store them properly until next season.


Regular air conditioner maintenance is essential for efficient operation, long lifespan, and improved air quality.
