How to Prepare Your A/C for the Off-Season

As the temperatures cool down, it’s time to start preparing your A/C system for the off-season. Taking the right steps now can help extend the lifespan of your unit and ensure it’s ready for the next cooling season. Blanco A/C, Electrical, & Plumbing, serving Johnson City, Dripping Springs, Spring Branch, and Canyon Lake, shares how to get your A/C ready for the off-season.

1. Clean or Replace the Air Filter

Your air filter likely accumulated a lot of dust, dirt, and allergens over the summer. Cleaning or replacing it will keep your system efficient and maintain good indoor air quality during the cooler months.

Expert Tip: Check your filter regularly, even in the off-season, and replace it every 1-3 months to keep your system in top condition.

2. Clean the Outdoor Unit

Throughout the summer, dirt, leaves, and debris can build up around your outdoor A/C unit. Use a garden hose to gently wash away the debris and clear the area around the unit to ensure proper airflow.

Expert Tip: Keep at least two feet of clearance around your outdoor unit to prevent any obstructions that could hinder its performance.

3. Inspect and Seal Ductwork

Leaky ducts can cause energy loss and reduce your system’s efficiency. Inspect your ductwork for any cracks, gaps, or damage, and seal them with duct tape or mastic sealant to prevent air leaks.

Expert Tip: Consider hiring a professional to inspect your ductwork for hidden leaks and ensure your system operates efficiently.

4. Adjust Thermostat Settings

If you have a programmable thermostat, adjust it to reflect the cooler weather. Set the thermostat to a higher temperature or switch it to “off” to prevent your A/C from running unnecessarily during fall and winter.

Expert Tip: A smart thermostat can adjust settings automatically, helping you save energy and money during the off-season.

5. Cover the Outdoor Unit

Protect your outdoor unit from weather damage by covering it with a breathable, weather-resistant cover. This helps prevent debris, moisture, and pests from damaging the unit while it’s not in use.

Expert Tip: Avoid using plastic covers, as they can trap moisture and lead to rust or mold. Choose a cover designed specifically for A/C units.

6. Schedule a Professional Maintenance Check

A professional tune-up ensures that your A/C is in optimal condition and ready for the next cooling season. Technicians can clean the system, identify potential issues, and make necessary repairs to keep your unit running efficiently.

Expert Tip: Regular maintenance can extend the life of your A/C system and prevent unexpected breakdowns.

7. Check for Unusual Noises or Smells

Before shutting down your A/C, pay attention to any unusual noises or odors that could indicate a problem. Rattling, banging, or grinding sounds may suggest loose components, while musty smells could indicate mold or mildew.

Expert Tip: Addressing these issues now can save you from costly repairs when you start using your A/C again next year.

8. Turn Off the Power Supply

For added safety, turn off the power supply to your A/C unit at the breaker box to prevent accidental activation during the off-season. This step also protects the unit from potential power surges.

Expert Tip: Label the breaker switch for easy identification when it’s time to turn the power back on.
