Welcome to the Kettering-Oakwood Heating & Cooling blog! We’re here to help you maintain a comfortable and efficient home environment throughout the year. Proper upkeep of your air conditioning system is crucial for its longevity, efficiency, and effectiveness, particularly during the hot summer months. In this detailed guide, we provide an essential AC care checklist to help you boost performance and save on energy expenses. 

The Importance of Routine AC Maintenance

Before we explore the checklist, let’s understand why regular maintenance is vital: 

  • Boosted Efficiency: Keeping your AC system in good shape means it operates more efficiently, translating to lower energy costs. 
  • Prolonged Lifespan: Routine check-ups can extend the lifespan of your air conditioner, postponing the need for expensive replacements. 
  • Better Air Quality: A clean system enhances indoor air quality by minimizing dust and allergens. 
  • Reduced Repair Expenses: Early detection of problems can help avoid costly repairs. 

The Essential AC Maintenance Checklist 

1. Examine and Change Air Filters 

  • Frequency: Every 1 to 3 months. 
  • Importance: Dirty filters obstruct airflow, decreasing efficiency and potentially allowing dirt into the system. 
  • Steps: Shut down the unit, remove the filter, and check its condition. If dirty, replace it with one that matches your system’s specifications. 

2. Inspect and Clean Coils 

  • Frequency: Once a year. 
  • Importance: Dirt on evaporator and condenser coils hampers their heat absorption capability. 
  • Steps: A technician should handle this, but you can check for visible debris and clean it gently, avoiding damage to the coil fins. 

3. Verify Thermostat Settings 

  • Frequency: With each season change. 
  • Importance: Ensures a comfortable indoor temperature. 

4. Inspect Electrical Connections 

  • Frequency: Annually. 
  • Importance: Loose connections can compromise safety and reduce component lifespan. 
  • Steps: Disable power, check connections, and tighten as needed. Have a professional inspect it annually for safety. 

5. Lubricate Moving Components 

  • Frequency: Annually. 
  • Importance: Minimizes friction in motors and extends their lifespan. 
  • Steps: Refer to the unit manual for lubrication points. When in doubt, consult a professional. 

6. Unclog the Condensate Drain Line 

  • Frequency: Annually. 
  • Importance: Blocked drains hinder humidity reduction, raising indoor moisture. 
  • Steps: Find the drain line, flush with a water-vinegar mix to clear it. Avoid harsh chemicals that might damage pipes. 

7. Check Ductwork for Leaks 

  • Frequency: Annually. 
  • Importance: Leaks lead to significant energy waste. 
  • Steps: Visually inspect ducts for holes or loose connections. Use mastic sealant or aluminum foil tape for small fixes. 

8. Assess Fan and Motor 

  • Frequency: Annually. 
  • Importance: A malfunctioning fan or motor affects overall system performance. 
  • Steps: Check for debris and signs of wear, and listen for odd noises. Contact a professional for any issues. 

9. Clean the Outdoor Unit 

  • Frequency: Annually. 
  • Importance: Debris can limit airflow and decrease efficiency. 
  • Steps: Clear away debris like leaves and branches, and gently clean fins with a garden hose. 

10. Arrange a Professional Maintenance Check 

  • Frequency: Annually. 
  • Importance: Professionals can spot and fix issues you might miss. 
  • Steps: Arrange an annual tune-up with Kettering-Oakwood Heating & Cooling to keep your system in top shape.
