Welcome to the Centerville Heating & Cooling blog. We are committed to ensuring your home remains comfortable and efficient throughout the year. Proper maintenance of your air conditioning system is essential, especially during those hot summer days, to keep it running smoothly and to prolong its lifespan. In this blog, we’ll share a comprehensive checklist to guide you through essential AC maintenance tasks. By keeping up with these steps, you can enhance your system’s efficiency and save on energy bills. 

Why Regular AC Maintenance is Important 

Before diving into the checklist, let’s explore why routine maintenance is crucial: 

  • Improved Efficiency: A well-maintained AC unit uses less energy, leading to lower utility bills. 
  • Extended Lifespan: Regular checks can extend your unit’s life, postponing the need for costly replacements. 
  • Enhanced Air Quality: Maintaining a clean system improves indoor air quality, reducing dust and allergens. 
  • Reduced Repair Costs: Early detection of issues can prevent expensive repairs down the line. 

Your AC Maintenance Checklist: 

1. Check and Replace Air Filters 

  • Frequency: Every 1-3 months. 
  • Importance: Dirty filters obstruct airflow and force the system to work harder, reducing efficiency. 
  • Method: Turn off the system, remove the filter, and inspect it. If it’s dirty, replace it with a new one that fits your system specifications. 

2. Inspect and Clean Coils 

  • Frequency: Once a year. 
  • Importance: Dirty coils hinder heat absorption, affecting cooling performance. 
  • Method: While professional techs should handle thorough cleaning, you can visually inspect for large debris and gently clean as needed. 

3. Verify Thermostat Settings 

  • Frequency: With every season change. 
  • Importance: Ensures your home is kept at a comfortable temperature. 

4. Examine Electrical Connections 

  • Frequency: Yearly. 
  • Importance: Faulty connections can cause unsafe operation and premature component failure. 
  • Method: Turn off the power to your system, inspect connections, and tighten any loose ones. A professional should conduct a thorough annual inspection. 

5. Lubricate Moving Parts 

  • Frequency: Annual check. 
  • Importance: Proper lubrication reduces motor friction and prolongs the life of parts. 
  • Method: Refer to your unit’s manual for lubrication points. If unsure, consult a professional. 

6. Clear the Condensate Drain Line 

  • Frequency: Once a year. 
  • Importance: A blocked condensate drain can raise humidity levels indoors. 
  • Method: Find the drain line and use a mixture of water and vinegar to clear blockages. Avoid harsh chemicals to prevent pipe damage. 

7. Inspect Ductwork for Leaks 

  • Frequency: Annually. 
  • Importance: Leaky ducts can waste a significant amount of energy. 
  • Method: Conduct a visual inspection of accessible ducts for leaks. Use mastic sealant or aluminum foil tape for minor fixes. 

8. Check the Fan and Motor 

  • Frequency: Annually. 
  • Importance: Problems with the fan or motor can greatly reduce system performance. 
  • Method: Look for debris and signs of wear and listen for unusual sounds. Call a professional if anything seems amiss. 

9. Clean the Outdoor Unit 

  • Frequency: Yearly. 
  • Importance: Leaves and other debris can block airflow and affect efficiency. 
  • Method: Clear away any debris and carefully rinse the unit’s fins with a garden hose. 

10. Schedule Professional Maintenance 

  • Frequency: Annually. 
  • Importance: Professionals can spot and address issues you might overlook. 
  • Method: Contact Centerville Heating & Cooling to schedule your yearly maintenance service to ensure optimal system performance.
