Preparing Your Air Conditioner for Winter

Though air conditioners aren’t typically used during the colder months, winterizing your system can protect it from damage and ensure it’s ready to go when warmer weather returns.

1. Turn Off the Outdoor Unit

• Why it’s important: If you live in a climate where temperatures drop significantly in winter, you won’t need your AC running. Keeping the unit off protects it from unnecessary wear and tear during cold weather.
• What to do: Shut off the power to the outdoor unit by locating the switch near the unit or on the electrical panel. This prevents the AC from accidentally turning on during unseasonably warm days.

2. Clean and Cover the Outdoor Unit

• Why it’s important: Snow, ice, and debris can damage the outdoor condenser unit over time. Protecting it from the elements is key to prolonging its lifespan.
• What to do: Clean the unit thoroughly, removing any debris, dirt, or fallen leaves. Once cleaned, place a weatherproof cover over the unit to protect it from snow and ice build-up. Be sure to use a cover specifically designed for air conditioners to ensure proper ventilation and prevent moisture build-up.

3. Insulate Exposed Pipes and Ducts

• Why it’s important: The pipes and ducts that connect your AC system to your home can freeze and crack in cold weather, leading to costly repairs.
• What to do: Insulate any exposed pipes or ducts with foam pipe covers or insulation tape. This is particularly important if your unit is located in an unheated area like a basement or attic.

4. Inspect and Clean Vents

• Why it’s important: During the winter, you may switch to using your heating system, but your AC’s ductwork will still be in use. Blocked or dirty vents can reduce efficiency and air quality.
• What to do: Check all air vents in your home for dust or obstructions. Vacuum or clean them thoroughly and ensure furniture or other items aren’t blocking airflow.

5. Change the Air Filters

• Why it’s important: As with summer, clean air filters are essential for good indoor air quality and efficient airflow. Even if you aren’t using your AC much during the winter, changing filters will help prevent dust and allergens from circulating in your home.
• What to do: Replace your air filters at the start of winter, and continue to check them regularly, especially if you’re using the same ductwork for heating.

6. Check the Insulation in Your Home

• Why it’s important: Proper insulation ensures that your home retains heat during winter, but it also means that your air conditioner will work more efficiently when it’s time to use it again in the summer.
• What to do: Inspect the insulation in your attic, walls, and around windows and doors. Adding insulation where needed will make both your heating and cooling systems more effective.

 

Final Thoughts

Taking the time to prepare your air conditioner for both summer and winter can save you money on energy bills, prolong the life of your unit, and help you avoid costly repairs. Regular maintenance not only ensures that your system runs efficiently when you need it most but also keeps your home comfortable throughout the year.

By following these simple steps each season, you can keep your air conditioner in great condition, no matter the time of year. If you’re ever unsure about what needs to be done, don’t hesitate to consult with an HVAC professional to ensure your system is properly maintained and ready for the weather ahead.
