As the days grow shorter and the temperature begins to drop, it’s time to start thinking about how to properly close down your air conditioner (AC) for the fall and winter seasons. Many homeowners overlook the importance of preparing their AC units for the colder months, but taking the time to do so can prolong the life of your system, reduce energy costs, and ensure that your unit is ready to go when the heat returns. This blog will walk you through the steps to safely and effectively close down your air conditioner and why scheduling regular maintenance and AC repair services is essential.

The Importance of Winterizing Your AC Unit

Your air conditioner works hard all summer, keeping your home cool and comfortable. However, neglecting to properly shut it down for the winter can result in damage from harsh weather conditions like snow, ice, and freezing temperatures. Preparing your system for the colder months protects it from these elements and helps avoid costly repairs in the spring. Winterizing your AC also keeps your unit free from debris buildup, such as leaves and dirt, which can clog filters and reduce efficiency.

Guide to Shutting Down Your AC

1. Turn Off the AC Unit

The first step in winterizing your AC is turning off the power to the unit. This prevents it from accidentally turning on during a warm fall day, which can damage the system when outdoor temperatures drop back down. Locate the exterior power switch, usually housed in a small box mounted near the unit. Flip the switch to the “off” position to ensure that no electricity is flowing to the AC. 

In addition, it’s wise to switch off the breaker dedicated to your AC inside the circuit breaker panel. This adds another layer of protection against power surges or accidental reactivation during the winter.

2. Clean the Unit Thoroughly

Over the summer, your AC unit likely accumulated dirt, dust, leaves, and other debris. Before shutting it down, thoroughly clean the system to prevent any buildup from causing damage or reducing efficiency. Start by removing any large debris from the exterior, such as twigs or leaves, using a broom or brush. Next, use a garden hose to gently rinse off the condenser coils, being careful not to damage the fins. Allow the unit to dry completely before proceeding to the next step.

3. Inspect the AC for Damage

Before you cover the unit for the winter, it’s important to inspect it for any signs of damage or wear. Look for cracks in the casing, rust on the metal components, and bent or damaged fins on the condenser coil. If you notice any issues, contact a professional HVAC technician to assess the damage and perform any necessary repairs. Regular inspections and prompt AC repair services can help extend the life of your unit and prevent more costly repairs in the future.

4. To Cover or Not To Cover the Unit

While there are two schools of thoughts on whether you should cover your AC unit, we believe it’s best to only cover the top of the unit, especially if you live in an area with a lot of trees. We do not recommend a full cover for your AC unit. The top cover will help prevent leaves, twigs, and other debris from entering the system. While full-sized AC covers may look nice, they can do more damage. Your AC unit is designed to be outside year-round. They are built with study metal covering to resist the elements, including snow and rain. The full cover will trap the moisture in your unit and can cause mold and may cause rust in your air conditioner, shortening the life of your system and requiring replacement parts before the Summer season begins. Another negative aspect of a full cover is that this warm covered unit makes a nice and warm environment for mice and other small animals to occupy your unit.

 You may also want to place a plywood board on top of the unit before covering it to shield it from heavy snow and ice.

5. Check the Thermostat

If you have a programmable thermostat, you’ll want to adjust the settings for the cooler months. Set the thermostat to a low temperature or switch it to heating mode if your system controls both heating and cooling. This step helps ensure that your AC stays off during the winter and isn’t triggered by a sudden warm day.

6. Schedule a Fall HVAC Inspection

One of the most important steps you can take to ensure your air conditioner is ready for winter is to schedule a professional HVAC inspection. A technician will thoroughly inspect your entire system, checking for any signs of wear, tear, or damage. They’ll also make sure your AC is functioning optimally and provide any necessary maintenance, such as replacing filters or lubricating moving parts. 

Scheduling regular inspections and maintenance can help prevent unexpected breakdowns and extend the life of your system. If any issues are identified during the inspection, the technician can provide AC repair services before the problem worsens. Regular maintenance also ensures that your system is energy-efficient, helping you save on energy bills during the cooling season.

The Role of AC Repair Services in Keeping Your System Healthy

Regular maintenance and timely repairs play a crucial role in the health and longevity of your air conditioner. Even with the best care, parts of your AC can wear out over time, leading to decreased efficiency or system failure. By addressing these issues early with professional AC repair services, you can avoid more expensive and extensive repairs down the line.

Some common signs that your AC may need repair include strange noises, reduced airflow, uneven cooling, and increased energy bills. If you notice any of these symptoms while preparing your system for the winter, contact an HVAC professional immediately. Ignoring these signs can lead to more severe damage, resulting in costly repairs or even the need for a full system replacement.

Additional Tips for Winterizing Your AC

1. Trim Vegetation: Before covering your AC, make sure that there are no overhanging branches, plants, or shrubs near the unit. Trim back any vegetation to at least two feet away from the system to allow for proper airflow and prevent leaves or branches from falling onto the unit.

2. Check the Drainage System: Ensure that the drainage system around your AC is clear of debris. Proper drainage prevents water from pooling around the base of the unit, which can lead to rust and damage during the winter months.

3. Seal Any Gaps: If your air conditioning unit is connected to your home through ducts or piping, check for any gaps or openings where cold air could enter. Use weatherstripping or insulation to seal these gaps, helping to keep your home warm and energy-efficient during the winter.

The Benefits of Regular AC Maintenance

Regular maintenance is essential to keeping your air conditioner running smoothly. Scheduling routine inspections and maintenance not only helps extend the life of your unit but also ensures that it operates at peak efficiency. This can result in lower energy bills and fewer costly repairs in the long run. 

By investing in professional AC repair services, you can rest assured that your system is in good hands. An experienced technician can identify potential problems early, provide necessary repairs, and offer advice on how to best care for your system year-round.
