- Improved Efficiency: A well-maintained AC unit operates more efficiently, which translates to lower energy bills when you start using it again in the spring or summer.
- Warranty Compliance: Many AC manufacturers require regular maintenance to keep the warranty valid. Neglecting maintenance could void your warranty, leaving you responsible for all repair costs.
Essential Pre-Winter AC Maintenance Steps
Here’s a comprehensive checklist of pre-winter AC maintenance tasks you should perform:
Thorough Cleaning:
- Turn off the Power: Before you begin any cleaning or maintenance, disconnect the power to your AC unit at the breaker box. This is essential for your safety.
- Remove Debris: Clear away any leaves, twigs, grass clippings, and other debris that have accumulated around the unit. Use a broom, brush, or vacuum to remove debris from the fins and coils.
- Clean the Fins: The fins are delicate, so use a fin comb or a soft brush to gently straighten any bent fins. This will improve airflow and efficiency.
- Wash the Unit: Use a garden hose with a gentle spray nozzle to wash the exterior of the unit. Avoid spraying water directly into the electrical components.
- Clean the Inside (if accessible): Some AC units have removable panels that allow you to access the interior. If you can safely access the inside, use a vacuum to remove any dust or debris.
Cover the Unit:
- Choose the Right Cover: Invest in a high-quality AC cover that is designed to protect your unit from the elements. Avoid using plastic tarps, as they can trap moisture and promote corrosion.
- Secure the Cover: Make sure the cover is securely fastened to the unit to prevent it from blowing away in strong winds.
Inspect for Damage:
- Check the Wiring: Look for any signs of frayed or damaged wiring. If you find any issues, contact a qualified electrician to make the necessary repairs.
- Inspect the Refrigerant Lines: Check the refrigerant lines for leaks or damage. If you suspect a leak, contact an HVAC professional to have it repaired.
- Examine the Fan Blades: Make sure the fan blades are in good condition and not damaged or bent.
- Check the Base: Inspect the base of the unit for cracks or damage. If you find any issues, contact a professional to have them repaired.
Lubricate Moving Parts:
- Identify Lubrication Points: Consult your AC unit’s owner’s manual to identify the lubrication points. These may include the fan motor bearings and other moving parts.

- Apply Lubricant Sparingly: Apply a small amount of lubricant to each lubrication point. Avoid over-lubricating, as this can attract dirt and debris.
Seal Gaps and Openings:
- Inspect for Gaps: Check around the AC unit for any gaps or openings that could allow pests to enter.
- Seal with Caulk or Foam: Use caulk or expanding foam to seal any gaps or openings. This will help prevent pests from entering and protect the unit from the elements.
Change the Air Filter (if applicable):
- Locate the Air Filter: Some AC units have an air filter that needs to be changed regularly. Consult your owner’s manual to locate the air filter.
- Replace the Filter: Replace the old air filter with a new one. This will improve airflow and efficiency when you start using the unit again.
Consider Professional Maintenance:
- Schedule a Checkup: If you’re not comfortable performing all of these maintenance tasks yourself, consider scheduling a professional AC checkup. An HVAC technician can thoroughly inspect your unit, identify any potential problems, and perform necessary repairs.
- Refrigerant Check: A professional can also check the refrigerant levels and add refrigerant if needed.
Additional Tips for Pre-Winter AC Maintenance
- Read the Owner’s Manual: Your AC unit’s owner’s manual contains valuable information about maintenance and troubleshooting. Be sure to read it carefully before performing any maintenance tasks.
- Keep Records: Keep a record of all maintenance tasks you perform, including the date, description of the work, and any parts replaced. This will help you track your maintenance efforts and identify any recurring problems.
- Don’t Neglect the Indoor Components: If you have a central AC system, don’t forget to maintain the indoor components as well. Clean the vents and ducts to remove dust and debris.
- Protect the Condenser Pad: The condenser pad is the concrete slab that your AC unit sits on. Make sure the pad is level and in good condition. If it’s cracked or damaged, contact a professional to have it repaired.
