How to Winterize Your Central Air Conditioning Unit

Winter is here in Pennsylvania, and it brings freezing temperatures and the possibility of snow and ice. These weather conditions can wreak havoc on your outdoor air conditioning unit, so it is necessary to take the proper precautions to ensure your HVAC system doesn't become damaged during the colder months. Many homeowners aren’t confident in protecting their HVAC units before the winter weather strikes but utilizing professional air conditioning services can help you through this process. That’s where the experts at Werley come in! Below, we’ll explore the steps you can take to protect your unit in the winter, including some tips for winterizing your AC on your own.

How Do You Protect an Air Conditioner in the Winter?

Protecting your outdoor AC unit during the winter is crucial to ensure it functions optimally when warmer weather returns. Here's a step-by-step guide to keeping your AC in the best shape possible for the next season:

Disconnect Power

Before you start winterizing your AC unit, it’s essential to turn off the power. Locate the disconnect switch near the outdoor condenser unit and switch it off. This prevents any accidental starts during surprisingly warm winter days.

Clean Your Unit

Remove leaves, dirt, branches, and other debris around and on your unit. You can use a hose to wash away grime and build-up but avoid using high pressure on the fins. Gently clean the evaporator and condenser coils using a coil cleaner. It’s also a good time to check for mold and mildew growth.

Change the Filters

Regularly changing the air filters is a simple yet effective way to keep your AC in optimal shape. Slide out the old filter and insert a new one, ensuring it fits securely in its slot.

Insulate the Refrigerant Lines

To prevent freezing, it's crucial to insulate the refrigerant lines. Wrap the exposed sections of the lines with foam pipe insulation. This helps maintain the temperature of the refrigerant and prevents condensation, which could lead to ice formation and damage.

Schedule Regular Maintenance After the Winter Weather

Scheduling regular maintenance tune-ups after the winter weather ensures your system is in top-notch condition for summertime. Regular care extends the lifespan of your AC and prevents unexpected breakdowns during crucial times.
