AC Maintenance Made Simple: Keep Your System Running All Summer Long
July 18, 2025
Regular air conditioning maintenance keeps your system running efficiently throughout summer while preventing costly breakdowns. Simple care steps and knowing when to call professionals ensures optimal performance during hot weather.
Filter Replacement Schedule
Clean filters are essential for AC efficiency and preventing system damage. Dirty filters are the leading cause of air conditioning problems, restricting airflow and causing systems to work harder while providing less cooling comfort.
- Standard filters should be replaced every 30-90 days during heavy use
- Check monthly during peak summer season
- Upgrade to pleated filters for better air quality and longer life
- Keep spare filters on hand for quick replacement
- Mark your calendar or set phone reminders for regular changes
During Bellingham's summer season, increased system runtime means filters collect dust and debris more quickly. Pet hair, pollen, and everyday household dust can clog filters surprisingly fast when your AC runs frequently to maintain comfort.
Outdoor Unit Care
Your outdoor condenser needs attention to function properly and maintain efficiency. This unit does the heavy lifting of heat removal and faces constant exposure to weather, debris, and environmental factors that can impair performance.
Your outdoor condenser needs attention to function properly:
- Clear debris, leaves, and grass clippings from around the unit
- Maintain at least 2 feet of clearance on all sides
- Gently rinse coils with a garden hose to remove dirt buildup
- Check for bent fins and carefully straighten with a fin comb
- Ensure the unit sits level on its pad
Restricted airflow around the outdoor unit forces your AC to work harder and can lead to premature failure. Landscaping should be designed to provide adequate clearance while protecting the unit from damage during lawn maintenance activities.
Indoor System Maintenance
Keep indoor components clean and functional to ensure optimal airflow and system performance. The indoor portion of your AC system handles air circulation and filtration, making regular maintenance essential for both comfort and air quality.
Keep indoor components clean and functional:
- Vacuum supply and return vents regularly
- Check that vents aren't blocked by furniture or curtains
- Clean the area around your indoor unit
- Inspect drain lines for clogs or backup
- Listen for unusual noises indicating potential problems
Blocked vents force your system to work harder and create uneven temperatures throughout your home. Furniture placement should allow free airflow, and decorative vent covers should never restrict air movement.
Thermostat Optimization
Proper thermostat use improves efficiency:
- Set temperatures reasonably (78°F is recommended for summer)
- Use programmable features to adjust when you're away
- Replace batteries annually or when low battery warning appears
- Keep thermostat away from heat sources and direct sunlight
- Consider upgrading to a smart thermostat for better control
Warning Signs Requiring Professional Help
Call a technician immediately if you notice:
- Warm air blowing from vents when cooling is selected
- Unusual noises like grinding, squealing, or banging
- Frequent cycling on and off
- Ice formation on indoor or outdoor units
- Sudden increases in energy bills
- Weak airflow throughout the house
Energy Efficiency Tips
Maximize your system's efficiency:
- Use ceiling fans to circulate cool air
- Close curtains during the hottest parts of the day
- Seal air leaks around windows and doors
- Avoid heat-generating activities during peak hours
- Consider upgrading to a programmable thermostat
Preparing for Professional Service
When scheduling professional maintenance:
- Clear access to both indoor and outdoor units
- Note any specific problems or concerns
- Have your system model and age information available
- Ask about service agreements for regular maintenance
- Discuss any efficiency concerns or upgrade options
Keep your AC running smoothly all summer long. Schedule professional maintenance today to ensure efficient, reliable cooling throughout the season.
