As the colder months approach, homeowners often focus on preparing their heating systems for the winter, but it’s just as important to ensure that your air conditioning (AC) system is properly shut down and prepared. Neglecting this task can lead to damage, costly repairs, or a shorter lifespan for your AC unit. While winterizing your AC might seem simple, many homeowners make common mistakes that can negatively impact their system.
To help you protect your investment and avoid unnecessary headaches, here are some common mistakes to avoid when preparing your air conditioning system for winter:
1. Skipping a Thorough Cleaning
One of the biggest mistakes homeowners make is neglecting to clean the AC unit before winter. Dirt, leaves, and other debris can accumulate on the condenser, clogging the system and causing damage over time. Before shutting down your AC for the season, it’s essential to give the outdoor unit a thorough cleaning.
What to Do:
Remove any debris, such as leaves or twigs, from around the unit.
Use a garden hose to gently wash away dirt and dust from the condenser coils.
Ensure there are at least two feet of clearance around the unit to prevent future debris buildup.
By taking the time to clean the unit, you’re preventing damage that could occur from debris sitting inside the system during the winter months.
2. Forgetting to Replace or Clean the Air Filter
Many homeowners overlook the importance of cleaning or replacing the air filter when preparing the AC for winter. A dirty air filter reduces airflow, decreases efficiency, and can lead to more significant issues when you restart the system in the spring.
What to Do:
Check the air filter and replace it if it’s dirty or clogged.
Consider upgrading to a high-efficiency filter to improve air quality and system performance.
Even though your AC won’t be in use during the winter, a clean filter ensures that it’s ready to go when you need it again.
3. Not Covering the Outdoor Unit Properly
A common misconception is that you need to fully cover your AC unit for the winter. While it’s essential to protect your system from snow, ice, and debris, completely covering it can trap moisture and lead to rust or mold growth.
What to Do:
Use a breathable cover designed specifically for outdoor AC units. These covers protect against debris while allowing moisture to escape.
If you don’t have a specialized cover, consider placing a piece of plywood over the top of the unit to shield it from falling debris, while still allowing air to circulate.
Avoid using plastic or other non-breathable materials, as they can trap moisture and cause damage to the unit.
4. Neglecting to Shut Off the Power
Another common mistake is leaving the power supply to the AC unit on throughout the winter. This can lead to accidental start-ups during unseasonably warm days, which could damage the system when temperatures drop again. Additionally, leaving the power on exposes the unit to unnecessary wear and tear.
What to Do:
Locate the AC’s electrical circuit on your home’s breaker panel and switch it off.
If your AC unit has an external shut-off switch near the unit, turn that off as well.
This step ensures that the system won’t accidentally run during the winter months and protects it from electrical damage.
5. Not Scheduling a Professional AC Maintenance Check
Some homeowners believe that shutting down their AC for the winter is a simple DIY task and skip scheduling a professional maintenance check. While there are many tasks you can handle on your own, a professional technician can catch issues you might overlook and ensure that the system is in peak condition before you shut it down for the season.
What to Do:
Schedule a maintenance appointment with an HVAC professional before winter hits.
A technician will inspect the system, perform a thorough cleaning, and ensure all components are functioning correctly.
This preventative maintenance can help identify potential problems early, saving you from costly repairs when you start using the AC again in the spring.
6. Ignoring the Thermostat
Leaving your thermostat settings unchanged when transitioning to winter is a mistake that can cause unnecessary strain on both your AC and heating systems. Switching the thermostat to “heat” and adjusting the temperature accordingly is crucial.
What to Do:
Set your thermostat to “heat” and choose an energy-efficient temperature.
If you have a programmable or smart thermostat, adjust the schedule to match your winter heating needs.
Ensuring your thermostat is correctly set will prevent your AC from running unexpectedly and will keep your home comfortable during the colder months.
7. Failing to Inspect the Ductwork
Many homeowners overlook the importance of checking their ductwork before winter. Leaks or blockages in the ducts can reduce the efficiency of both your AC and heating systems, leading to higher energy bills and reduced comfort.
What to Do:
Inspect the ductwork for any visible leaks or damage.
Seal any gaps or leaks with duct tape or a professional sealant.
Consider scheduling a professional duct cleaning to remove dust and debris that could impact system performance.
Properly sealed ducts improve airflow, ensuring both your AC and heating systems work efficiently.
8. Overlooking the Importance of Insulation
While insulation is often associated with heating, it also plays a crucial role in maintaining your AC system’s efficiency during the summer months. By ensuring your home is properly insulated before winter, you’re helping to protect your AC system when it’s not in use.
What to Do:
Check the insulation in your attic, walls, and around windows and doors.
Add extra insulation where needed to improve energy efficiency.
Good insulation keeps your home warm in the winter and reduces the workload on your AC when the warmer months return.
