AC Maintenance Checklist

This article outlines the key steps to include in your AC maintenance routine.

Before the Summer Season:

  1. Clean or Replace Air Filters: Start your AC maintenance by cleaning or replacing the air filters. According to the reputable AC service providers behind ac repair Rockwall , clogged or dirty filters restrict airflow, reducing the efficiency of your AC system.

    Cleanable filters should be washed thoroughly and allowed to dry before reinstallation. Disposable filters need to be replaced with new ones. Check the manufacturer’s recommendations for the appropriate filter type and frequency of replacement.
  1. Clear Debris from Outdoor Unit: Inspect the outdoor unit (condenser) and remove any leaves, dirt, or debris that may have accumulated. Ensure there is no vegetation obstructing the unit’s airflow. Trim bushes or plants around the condenser to maintain at least two feet of clearance on all sides.
  1. Check and Clean the Condenser Coils: Over time, the condenser coils can collect dirt and debris, reducing efficiency. Use a soft brush or a fin comb to clean the coils and remove any buildup gently. Be careful not to damage the delicate fins. If the coils are filthy, consider hiring a professional for a thorough cleaning.
  1. Inspect the Condensate Drain Line: The condensate drain line removes excess moisture from your AC system. Inspect the drain line for any clogs or blockages. Clear the line by flushing it with bleach and water or using a wet/dry vacuum to remove any buildup. Ensure that the drain line is draining properly.
  1. Test the Thermostat: Check the functionality of your thermostat. Ensure that it accurately reads the temperature and responds to changes in settings. Replace the batteries if necessary and consider upgrading to a programmable thermostat for better energy efficiency and comfort control.
  1. Inspect and Clean Vents and Registers: Check all the vents and registers throughout your home to ensure they are not blocked or obstructed by furniture, curtains, or other objects. Remove any dust or debris from the vents and registers using a vacuum cleaner or a soft brush.
  1. Test the AC System: Before the summer season begins, run a test cycle of your AC system to ensure it is operating correctly. Listen for unusual noises, check for proper airflow, and verify that cold air is coming from the vents. Contact a professional HVAC technician for further inspection and repair if you notice any issues.

After the Summer Season:

  1. Clean or Replace Air Filters: Similar to pre-summer maintenance, clean or replace the air filters after the summer season. This step helps remove accumulated dust and ensures your AC system is ready for the next cooling season.
  1. Clean the Indoor Evaporator Coil: The indoor evaporator coil can collect dirt and dust over time, affecting efficiency. Clean the coil using a soft brush or a specialized coil cleaner. Follow the manufacturer’s instructions and avoid bending the delicate fins. Cleaning the evaporator coil helps maintain proper cooling and airflow.
  1. Check and Clean the Blower Assembly: Inspect the blower assembly and clean any dust or debris that may have accumulated. A dirty blower assembly can reduce airflow and strain the system. Ensure that the blower motor and fan are functioning correctly, and lubricate them if necessary (check the manufacturer’s guidelines for lubrication).
  1. Inspect Ductwork for Leaks: Check the ductwork for any visible signs of leaks or damage. Leaky ducts can result in significant energy loss and reduced cooling efficiency. Inspect the joints and connections for any gaps or loose seals. Seal any leaks using aluminum foil tape or duct sealant. If you notice extensive damage or suspect a significant leak, it’s advisable to consult a professional HVAC technician for a thorough inspection and repair.
  2. Schedule Professional Maintenance: While you can perform many AC maintenance tasks independently, scheduling professional maintenance at least once a year is beneficial. A trained HVAC technician can conduct a comprehensive inspection, perform advanced cleaning, and identify any underlying issues that may require repair or adjustment. Professional maintenance helps optimize the performance of your AC system and ensures its longevity.

By following this AC maintenance checklist before and after the summer season, you can ensure that your AC system operates efficiently, provides optimal cooling comfort, and has a longer lifespan.

Regular maintenance saves you from unexpected breakdowns, improves energy efficiency, and lowers utility costs. Stay proactive with your AC maintenance to enjoy a cool and comfortable indoor environment all year round.
