What seasonal maintenance is required for American Standard air conditioners?

 
Filter Cleaning and Replacement
 

• Check and replace or clean air filters regularly to ensure efficient airflow and reduce strain on the system – a routine that many homeowners in St. Louis find essential.
• During spring and summer, inspect filters every 30 days and clean reusable filters or replace disposable ones as needed.
• Make sure the filter area is dust-free and undamaged, which can help prevent long-term performance issues.

 
Coil Cleaning
 

• Inspect both the evaporator and condenser coils for dirt, debris, and grime accumulation.
• Clean the coils gently using a soft brush or coil cleaner, ensuring that delicate fins aren’t bent or damaged.
• Clean coils seasonally, especially before the high-demand cooling months, to maintain effective heat exchange.

 
Checking Refrigerant Levels and Inspecting for Leaks
 

• Monitor refrigerant levels as part of the maintenance routine to ensure proper system performance.
• Inspect the refrigerant lines for signs of wear, damage, or leaks. Low refrigerant can reduce cooling efficiency and lead to costly repairs.
• If you suspect a leak, contact a professional technician to repair and recharge the system, as handling refrigerants requires certification.

 
Condensate Drain and Moisture Management
 

• Examine the condensate drain to ensure it is not clogged by algae, dust buildup, or debris.
• Clean the drain line periodically to avoid water backup, which can lead to mold growth and system malfunctions.
• Ensure that the condensate pan is free of standing water and that all connections are secure.

 
Electrical Component Inspection
 

• Check wiring connections and control components for signs of wear and corrosion.
• Ensure that all electrical contacts and relays are functioning properly to avoid unexpected shutdowns.
• It's advisable to schedule a professional inspection annually to verify all electrical components meet safety standards.

 
Lubrication of Moving Parts
 

• Inspect the fan motors and other moving components for excess friction or unusual noises.
• If applicable, lubricate motor bearings and moving parts with the recommended lubricant to ensure smooth operation.
• This task can help reduce energy consumption and extend the lifespan of the system.

 
Outdoor Unit Maintenance
 

• Clear leaves, twigs, and other debris from around the outdoor condenser unit, which is especially important for properties in St. Louis where seasonal weather can lead to more debris accumulation.
• Keep the area around the unit free of obstructions to ensure unobstructed airflow.
• Check that the fins are not bent and that the unit is firmly mounted with no physical damage from weather conditions.

 
System Performance Verification
 

• Test the thermostat for accuracy and adjust settings to match seasonal changes.
• Observe for any unusual system sounds or vibrations during startup and steady operation.
• Run a performance test to confirm the system cools efficiently after all maintenance steps have been completed.

 
Professional Inspection and Servicing
 

• Schedule an annual professional maintenance check-up, ideally at the beginning of the cooling season, to ensure in-depth diagnostics and repair.
• Professionals can verify refrigerant pressures, inspect internal components, and provide advanced cleaning, which might not be feasible through routine DIY methods.
• This service helps identify potential issues early, prolonging the system's life and maintaining energy efficiency.
