Summer is here, and ensuring your air conditioning unit works properly is crucial for maintaining a cool and comfortable home. When faced with air conditioning issues, it is essential to reach out to a trusted HVAC contractor immediately. To stay on top of necessary maintenance and scheduled services, having a comprehensive air conditioner maintenance checklist is invaluable.
Air Conditioner Maintenance Checklist
According to our thorough research general air conditioning maintenance must include the following checklist points:
This guarantees that your thermostat is correctly installed and positioned away from any heat-emitting sources, such as sunlight, lamps, and appliances that generate heat.
Clean or Replace the Air Filters
Regularly inspect and replace air filters to improve air quality and system efficiency. Dirty filters should be replaced immediately, but at a minimum, change them every three months.
Examine All The Electrical Components And Controls
Check all electrical connections, measure motor voltage, and tighten connections to optimize energy efficiency and functionality.
Ensure Your AC Is Level
Ensuring your AC unit is both level and firmly positioned on the ground is crucial. While placing your unit on pads is acceptable, it’s important to ensure the pads remain stable. Using rocks or concrete can prevent any shifting. If your unit begins to tilt, it’s advisable to consult with your AC professional to maintain the stability of the unit.
Check The Area Around The Condenser
Clear away leaves, and debris, and trim bushes near your outdoor unit to improve airflow. While it may be tempting to hide the AC unit behind shrubs and trees for aesthetic purposes, this can hinder airflow and cause your system to work harder than necessary.
Clean the Condensate Drain Line
Regularly cleaning the drain pipe prevents blockages that can lead to leaks and potential damage to the piping system.
Check the Refrigerant Levels and Leaks
Ensure your system has sufficient refrigerant to prevent overworking. Low levels may indicate a refrigerant leak that requires professional attention.
Clean the Evaporator and Condenser Coils
The evaporator and condenser coils are prone to accumulating dirt and mold. Regular cleaning improves unit efficiency and prolongs its lifespan.
If your evaporator coils get too cold, the warm air around them can condense and form ice. Ice buildup will cause your compressor to run at a high temperature and burn your unit out. Check your coils at least once a month during the fall and winter. When you notice ice, turn off your unit and wait for the ice to melt. Clean your coils and check your unit for any debris buildup or blockages that may keep the air around your coils from escaping.

Clean All Blower Components
Unclean blower components can hinder airflow and reduce system productivity. Regular cleaning prevents the circulation of debris and dirt throughout your home.
Lubricate All The Moving Parts
Properly lubricating parts reduce friction in motors and prevent increased electricity bills.
Seal Ducts Properly
Leaky ducts can reduce system efficiency. Consider sealing any leaks to prevent air from escaping into unwanted spaces in your home.
Inspect and Clean the Outdoor Unit
Perform a thorough inspection and cleaning of your AC’s outdoor unit as part of routine maintenance. Remove debris, dirt, and any obstructions to ensure optimal performance and longevity of the system.
Run the Final Test on Your AC System
After completing the preceding steps, proceed to test your AC unit. Switch on the power and allow it to run, remaining attentive for any uncommon noises.
