Welcome to the Springboro Heating & Cooling blog! Our mission is to help you maintain a comfortable and energy-efficient home throughout the year.

In this guide, we’ll walk you through a comprehensive AC maintenance checklist. By following these steps, you can optimize your system’s performance and save on energy expenses.
Why Routine AC Maintenance Is Important
Before diving into the checklist, let’s explore the importance of regular maintenance:
- Enhanced Efficiency: A well-maintained air conditioner operates more efficiently, resulting in lower energy bills.
- Prolonged Lifespan: Routine inspections can extend your unit’s lifespan, delaying the need for expensive replacements.
- Better Air Quality: Clean systems enhance indoor air quality by minimizing dust and allergens.
- Lower Repair Costs: Early problem detection can prevent expensive repairs.
Essential AC Maintenance Checklist
1. Replace Air Filters

- Frequency: Every 1-3 months.
- Importance: Blocked or dirty filters impede airflow and reduce efficiency, potentially allowing dirt to enter the system and cause issues.
- Steps: Turn off the system, remove the filter, and inspect it. Replace it if it’s dirty, ensuring the new filter is compatible with your system.
2. Clean Coils
- Frequency: Annually.
- Importance: Coils collect dirt, which reduces their ability to absorb heat.
- Steps: While professional assistance is recommended, homeowners can visually inspect for debris and clean it carefully without bending the coils.
3. Adjust Thermostat Settings

- Frequency: Seasonally.
- Importance: Keeps your home comfortably cooled.
- Steps: Ensure the thermostat is on the “cool” setting at the desired temperature. Consider upgrading to a smart or programmable thermostat.
4. Inspect Electrical Connections
- Frequency: Annually.
- Importance: Faulty connections can lead to unsafe operation and shorten component life.
- Steps: Turn off the unit’s power, inspect connections, and tighten any loose ones. Consider a professional inspection annually for safety.
5. Lubricate Moving Parts
- Frequency: Annually.
- Importance: Minimizes motor friction and prolongs component lifespan.
- Steps: Refer to the manual for lubrication points. Consult a professional if unsure.
6. Clear Condensate Drain Line
- Frequency: Annually.
- Importance: Prevents humidity reduction issues due to clogged drains.
- Steps: Find the drain line and use a water and vinegar solution to remove blockages. Avoid harsh chemicals to prevent pipe damage.
7. Check Ductwork for Leaks
- Frequency: Annually.
- Importance: Ensures minimal energy loss.
- Steps: Visually inspect ducts for holes or loose connections and use mastic sealant or aluminum foil tape for minor repairs.
8. Inspect Fan and Motor
- Frequency: Annually.
- Importance: Prevents major performance issues.
- Steps: Check for debris and wear. Listen for strange noises and call a professional if necessary.
9. Clean the Outdoor Unit
