Welcome to the Washington Court House Heating & Cooling blog, your resource for keeping your home comfortable and energy-efficient all year long. As a homeowner, ensuring your air conditioning system is well-maintained is essential for its durability, performance, and cost-effectiveness, especially when summer temperatures soar. In this detailed guide, we’ll provide an all-inclusive AC maintenance checklist to help you optimize your unit’s function and save on energy bills.
Why Consistent AC Maintenance is Vital
Before jumping into the checklist, it’s important to understand the benefits of routine maintenance:
- Improved Performance: A well-kept AC operates more efficiently, reducing your energy expenses.
- Prolonged System Life: Regular servicing can extend your unit’s lifespan, postponing the need for expensive replacements.
- Better Air Quality: Clean systems promote healthier air by minimizing dust and allergens.
- Lower Repair Expenses: Early problem detection can help you avoid costly repairs.
Essential AC Maintenance Tasks
1. Replace and Inspect Air Filters

- Frequency: Every 1-3 months
- Purpose: Dirty filters block airflow, decreasing efficiency and allowing dirt to enter the system.
- Method: Turn off the AC, remove the filter, and inspect it. Replace if dirty, ensuring the new filter matches your system’s specifications.
2. Clean and Inspect Coils
- Frequency: Once a year
- Purpose: Dirt on evaporator and condenser coils diminishes their heat absorption capability.
- Method: While a professional should typically handle this, you can check for visible debris and clean it carefully, avoiding bending the coil fins.
3. Adjust Thermostat Settings

- Frequency: At the start of each season
- Purpose: Keeps your home comfortably cool.
- Method: Ensure the thermostat is set to cooling mode and at the desired temperature. Consider upgrading to a smart or programmable thermostat.
4. Assess Electrical Connections
- Frequency: Annually
- Purpose: Faulty connections may result in unsafe operations and shorten component life.
- Method: With the unit powered down, inspect connections and tighten any that are loose. Hire a professional for a comprehensive annual safety check.
5. Lubricate Moving Components
- Frequency: Once a year
- Purpose: Decreases friction in motors, extending the life of parts.
- Method: Refer to your unit manual for lubrication points, or consult with a professional if uncertain.
6. Clear the Condensate Drain
- Frequency: Annually
- Purpose: Clogged drains prevent the system from lowering humidity and raising indoor moisture.
- Method: Locate the drain and use a solution of water and vinegar to clear clogs. Avoid harsh chemicals that might damage pipes.
7. Inspect Ductwork for Leaks
- Frequency: Annually
- Purpose: Leaky ducts can significantly increase energy waste.
- Method: Visually inspect ducts for visible holes or loose connections. Use mastic sealant or foil tape for minor repairs.
8. Check the Fan and Motor
- Frequency: Annually
- Purpose: A malfunctioning fan or motor can hinder system effectiveness.
- Method: Look for wear and debris, and listen for unusual sounds. Consult a professional for any issues.
9. Wash the Outdoor Unit
- Frequency: Once a year
- Purpose: Debris can obstruct airflow and lower efficiency.
- Method: Clear away visible debris like leaves or branches, and gently clean fins with a garden hose.
10. Arrange for Professional Service
- Frequency: Annually
- Purpose: Professionals can spot and solve issues that may go unnoticed.
- Method: Contact Washington Court House Heating & Cooling to schedule your yearly maintenance service for optimal system performance.
