How to Maintain Your Scanfrost Air Conditioner: Tips for Long-Lasting Performance

by admin

Your Scanfrost air conditioner is your haven during the hot months, providing a cool and comfortable environment. To ensure its efficiency and longevity, regular maintenance is crucial.

In this article, we’ll share steps and tips on maintaining your Scanfrost air conditioner to keep it in optimal condition for years to come.

  1. Regularly Clean or Replace the Filters: Clogged or dirty filters are one of the primary culprits of reduced AC efficiency. A dirty filter restricts airflow, causing the unit to work harder and, as a result, consume more energy.
  •     For reusable filters: Clean them every month during peak usage. Use mild detergent and warm water, rinse thoroughly, and let it dry completely before reinstalling.
  •     For disposable filters: Check monthly and replace them when they appear dirty, typically every 1-3 months. 
  1. Inspect the Condenser and Evaporator Coils: Over time, the coils can collect dirt, reducing the system’s ability to absorb and release heat. Clean the coils annually to maintain efficiency.
  •     The evaporator coil is typically located inside so you might need a technician for this step.
  •     For the condenser coil: Located outside, ensure it’s free from debris like leaves and dust. Gently clean it with a soft brush or garden hose. 
  1. Check the Coil Fins: The evaporator and condenser coils have aluminum fins that can easily bend, blocking airflow. You can realign them using a tool called a “fin comb,” available at most appliance parts stores.
  2. Maintain the Area Around the Unit: Ensure there’s at least a 2-foot clearance around outdoor units. Remove any debris, leaves, or plants that could restrict airflow or get inside the unit.
  3. 5. Inspect the Condensate Drain: Blocked drain channels can cause increased humidity inside, leading to potential mold and water damage. Use a stiff wire to occasionally push through the unit’s drain channels to clear any potential blockages.
  4. Check for Leaks: Contact a professional if you suspect a refrigerant leak. It’s essential to have the correct amount of refrigerant in the system, neither too much nor too little.


  1. Schedule Professional Maintenance: While DIY maintenance can handle most tasks, having a professional technician check your Scanfrost AC annually is beneficial. They can identify and address potential issues before they become significant problems, ensuring your unit’s longevity.
  2. Run Your AC Regularly: Even during cooler periods, running your air conditioner occasionally is a good idea. This helps in keeping the parts moving and identifies if there are any issues with its operation.
  3. Check and Tighten Electrical Connections: Loose connections can be a safety hazard and reduce the unit’s lifespan. With the power off, check the connections or have a technician do it during annual maintenance.
  4. Update the Thermostat: If you’re using an older thermostat model, consider upgrading to a programmable one. It ensures your AC operates at optimal efficiency and can save on energy costs.
  5. Maintaining your Scanfrost air conditioner is essential to ensure it operates efficiently and has a long lifespan. Proper maintenance will not only keep your home comfortable but also help you save on energy costs. Here are some tips for maintaining your Scanfrost air conditioner:
    1. Regular Cleaning:
      • Turn off the power to the unit before doing any maintenance.
      • Clean or replace the air filters at least once a month during the cooling season. Clogged filters can reduce airflow and make your AC work harder.
      • Clean the indoor and outdoor coils to remove dirt and debris that can obstruct airflow. Use a soft brush or a coil cleaning solution.
    2. Check for Blockages:
      • Ensure there are no obstructions around the outdoor unit. Leaves, grass, and other debris can clog the condenser coil and reduce efficiency.
    3. Check the Condensate Drain:
      • Inspect the condensate drain for clogs or blockages. A clogged drain can cause water damage and reduce cooling efficiency. Clean the drain if necessary.
    4. Inspect the Refrigerant Lines:
      • Check the refrigerant lines for any signs of wear or damage. If you notice any issues, call a professional technician to assess and repair the lines.
    5. Tighten Electrical Connections:
      • Periodically inspect and tighten electrical connections, including terminals and contacts. Loose connections can cause unsafe operation and reduce the lifespan of the unit.
    6. Lubricate Moving Parts:
      • Some air conditioner models have motors and other moving parts that require lubrication. Check your owner’s manual for guidance on which parts need lubrication and how often.
    7. Check the Thermostat:
      • Ensure the thermostat is working correctly and accurately reading the temperature. Replace the batteries if it’s a battery-operated thermostat.
    8. Schedule Professional Maintenance:
      • It’s advisable to have your Scanfrost air conditioner professionally serviced at least once a year. A technician can check for any major issues, clean and tune up the system, and ensure it’s running efficiently.
    9. Keep the Area Around the Indoor Unit Clean:
      • Maintain a clean and clutter-free area around the indoor unit to allow for proper airflow and operation.
    10. Use the Air Conditioner Wisely:
      • Set the thermostat to a reasonable temperature and avoid extreme temperature changes. Running the unit at maximum cooling or heating constantly can strain the system.
    11. Consider Installing a Programmable Thermostat:
      • A programmable thermostat can help you optimize your air conditioner’s operation by automatically adjusting the temperature according to your schedule.
    12. Seal Leaks in Ductwork:
      • If your Scanfrost air conditioner is connected to ductwork, ensure there are no leaks in the ducts. Leaky ducts can cause the system to work harder and reduce efficiency.

    By following these maintenance tips and keeping a regular schedule, you can ensure that your Scanfrost air conditioner operates efficiently and has a longer lifespan. Additionally, proper maintenance will help you avoid unexpected breakdowns and save on energy costs.

In conclusion, your Scanfrost air conditioner is a significant investment, and maintaining it should be a top priority.

Regular maintenance ensures efficient performance and extends the unit’s lifespan, saving you money in the long run. Whether you’re a DIY enthusiast or prefer professional assistance, these tips will help you keep your Scanfrost AC in peak condition.
