As winter approaches, it’s easy to forget about your air conditioning (AC) system since you won’t be using it to keep your home cool. However, maintaining your AC during the winter months is essential to ensure it’s in top condition when the warmer weather returns. Without proper care, your AC system can develop issues that lead to costly repairs or inefficiency when you need it most.
Here’s a comprehensive winter AC maintenance checklist to help you keep your system in excellent shape throughout the colder months. Our tips for Winter AC maintenance will keep your unit in peak shape.
Clean the Outdoor Unit (Condenser)
The outdoor condenser unit is often exposed to the elements, which can cause dirt, leaves, and debris to accumulate. This debris can clog the system, leading to reduced efficiency and even damage to the components. Clear any leaves, twigs, or debris from around the outdoor unit. Gently clean the unit’s fins using a soft brush or a vacuum to remove dust or dirt. Ensure there’s at least two feet of clearance around the unit for proper airflow. Cleaning the condenser will help prevent blockages and ensure your AC system remains in good condition over the winter.
Shut Off the Power to the AC
One of the most important steps in winterizing your air conditioner is turning off the power to the outdoor unit. If the AC accidentally turns on during a warmer winter day, it could cause damage to the system. Locate the AC’s electrical disconnect box, which is usually mounted on the wall near the outdoor unit, and flip the switch to shut off the power supply. Alternatively, you can turn off the breaker connected to your AC unit in your home’s electrical panel. By cutting off the power, you’re protecting your AC from unnecessary wear and tear during the winter.
Cover the Outdoor Unit
While it’s not always necessary to cover the outdoor unit entirely, providing some protection against winter weather is a good idea. Snow, ice, and falling debris can damage the unit if left unchecked. Use a breathable cover designed specifically for outdoor AC units to prevent debris and moisture buildup. If you don’t have a specialized cover, a piece of plywood placed on top of the unit can help shield it from debris. Avoid covering the unit with non-breathable materials, such as plastic, as this can trap moisture inside, leading to rust or mold.
Check and Clean the Air Filter
Even though your AC won’t be running during the winter, it’s still essential to check the air filter before shutting down the system for the season. A dirty or clogged filter reduces airflow, impacting both your AC and heating systems. Inspect the air filter and replace it if it’s dirty or clogged. Regularly check the filter throughout the winter months to ensure it remains clean. A clean filter improves the efficiency of your HVAC system and ensures better air quality in your home.
Inspect and Clean the Ductwork
The ductwork in your home is responsible for distributing conditioned air. Over time, dust, dirt, and other debris can build up inside the ducts, reducing airflow and efficiency. This can impact both your heating and cooling systems. Inspect the ductwork for any visible leaks or damage. Clean the vents and duct openings to remove dust and debris. Consider scheduling a professional duct cleaning if there’s significant buildup inside the ducts. Well-maintained ductwork ensures better airflow and system performance year-round.
Check the Thermostat
When transitioning from cooling to heating, it’s essential to adjust your thermostat settings. Leaving it set to “cool” during the winter months can result in accidental AC operation, which could damage the system. Switch your thermostat from “cool” to “heat” mode. Set the temperature to a comfortable level for winter. If you have a programmable or smart thermostat, adjust the schedule to match your winter heating needs. Proper thermostat settings prevent unnecessary AC operation and ensure your home stays comfortable during the winter.
Schedule Professional HVAC Maintenance
While many of the tasks on this checklist can be handled by homeowners, scheduling a professional HVAC maintenance check is essential for a thorough inspection and tune-up. A trained technician can identify any issues that may not be visible and ensure that your AC is in excellent condition for the next cooling season. Schedule an HVAC maintenance appointment before the winter season begins. A technician will inspect the entire system, perform a thorough cleaning, and check for any potential problems. This professional service ensures that your AC system will be ready to handle the summer heat when it’s time to switch back to cooling.
Check for Unusual Noises or Smells
If your AC system has been making strange noises or emitting unusual smells, it’s essential to address these issues before shutting it down for the winter. Ignoring these signs could lead to more significant problems down the road. Pay attention to any banging, grinding, or rattling sounds coming from the AC unit. Investigate any strange smells, such as burning or musty odors, which could indicate electrical issues or mold growth. If you notice any unusual noises or smells, it’s best to contact a professional for further inspection.
Inspect Insulation Around the Unit and Pipes
Proper insulation around the AC unit and refrigerant lines is crucial to protect them from freezing temperatures. Insulating these components ensures that they remain in good condition and prevents damage from freezing and thawing. Inspect the insulation around the refrigerant lines for any wear or damage. Replace or add insulation where necessary to protect the system from freezing temperatures. Good insulation helps maintain the efficiency of your HVAC system and protects it from the elements.
Seal Any Leaks or Gaps Around the Unit
Leaks or gaps around the AC unit can allow cold air and moisture to enter the system, causing damage or inefficiency. Sealing these gaps helps protect the system from harsh winter conditions. Inspect the area around the outdoor unit for any gaps or cracks in the walls or foundation. Use caulk or weatherstripping to seal any gaps, ensuring that the unit is protected from the cold. Sealing leaks prevents cold air and moisture from entering the unit, reducing the risk of damage.
