1. Clear Debris and Prepare the Exterior: Winter can be tough on your AC unit’s exterior. Before the first snowfall, take some time to clear any debris from around the outdoor unit. Leaves, branches, and dirt can accumulate and block airflow, potentially causing damage. Also, trim any overhanging branches or icicles that could fall onto the unit during winter storms. Keeping the area around your AC unit clear is the first step in protecting it from the elements.

2. Turn off the Power: Your AC unit doesn’t need to run during the winter, so it’s a good idea to turn off the power supply to it. You can do this in two ways:

Locate the electrical disconnect switch near your outdoor AC unit, often housed in a weatherproof box. Flip the switch to the “off” position to ensure the AC unit won’t accidentally turn on during freezing temperatures. Additionally, consider shutting off the circuit breaker that provides power to your AC unit. This double layer of protection ensures your system remains off throughout the winter.

3. Cover the AC Unit: Invest in an AC cover or use a sturdy tarp to shield the unit from snow, ice, and freezing rain. Covering your AC unit not only prevents moisture from getting inside but also protects it from the harsh winter weather. Remember, moisture can lead to rust and damage, so this simple step can go a long way in preserving your system.

4. Insulate Pipes and Ducts: Frozen pipes and ducts can spell trouble for your AC system. To prevent this, wrap exposed pipes and ducts with insulation. This helps maintain the temperature within the system and prevents freezing, which can lead to cracks and damage. Insulating these components also aids in energy efficiency, as it minimizes heat loss.

5. Schedule Professional Maintenance: Don’t underestimate the importance of a professional HVAC Maintenance before winter sets in. A qualified technician can identify potential issues and perform necessary maintenance tasks to ensure your AC system runs smoothly when you need it again. During the inspection, ask the technician to replace your air filter. Even during winter, your HVAC system may run occasionally, and a clean filter ensures optimal performance and indoor air quality.

6. Change the Air Filter: Regularly changing your air filter is a simple yet crucial task. A clean filter ensures your system runs efficiently, even if you’re not using it frequently in winter. It also helps maintain good indoor air quality, which is essential for a healthy home environment.

7. Keep the Area Clear: Throughout winter, make it a habit to clear snow and ice buildup from your AC unit. Accumulated snow and ice can block airflow and potentially cause damage to the unit. A few minutes of clearing away snow after each storm can save you from major headaches down the road.

8. Consider a Professional Maintenance Plan: If you want to take your AC system’s winter care to the next level, consider a professional maintenance plan. Many HVAC companies offer seasonal plans that include regular inspections and ensure your system is ready for each season. These plans can save you time and money in the long run by preventing costly issues.
