Beat the cold: comprehensive guide to covering central air conditioner during winter months
What To Know
- Use a soft brush or a vacuum cleaner to remove loose particles, and then rinse the unit with a garden hose.
- Cover the evaporator coil with a breathable material, such as cheesecloth or a furnace filter, to prevent dust and debris from accumulating.
- If your outdoor unit is not enclosed in a protective housing, consider covering it with a tarp or a custom-made cover.
As the chilly winds of winter approach, it’s crucial to prepare your home’s central air conditioner for the long months ahead. Proper winterization not only protects your unit from the elements but also ensures its longevity and efficiency when the warm weather returns. Here’s a step-by-step guide on how to cover a central air conditioner for the winter:
1. Clean the Unit
Before covering the unit, it’s essential to clean it thoroughly. Remove any dirt, debris, or leaves that may have accumulated during the summer months. Use a soft brush or a vacuum cleaner to remove loose particles, and then rinse the unit with a garden hose. Allow it to dry completely before proceeding.
2. Shut Off the Power
To ensure safety, turn off the power to the air conditioner at the electrical panel. This will prevent accidental operation while the unit is covered.
3. Remove the Condenser Unit Cover
Most central air conditioners have a condenser unit that is located outdoors. This unit contains the compressor and other essential components. Carefully remove the condenser unit cover, usually secured with screws or latches.
4. Cover the Condenser Unit
Using a heavy-duty tarp or a custom-made cover specifically designed for air conditioners, cover the condenser unit completely. Secure the cover tightly with bungee cords or straps to ensure it stays in place during windy conditions.
5. Disconnect the Refrigerant Lines
For units with exposed refrigerant lines, carefully disconnect them from the condenser unit. Use a wrench to loosen the nuts and gently pull apart the lines. Cap the disconnected ends to prevent moisture and debris from entering the system.
6. Protect the Electrical Wiring
Cover any exposed electrical wiring with electrical tape or heat-shrink tubing. This will prevent damage from moisture and rodents.
7. Install a Condenser Unit Blanket
For added protection, you can install a condenser unit blanket over the covered unit. These blankets provide an extra layer of insulation and protection from extreme weather conditions.
8. Prepare the Evaporator Coil
The evaporator coil is located inside the air handler, usually in the attic or basement. Turn off the power to the air handler and remove the access panel. Cover the evaporator coil with a breathable material, such as cheesecloth or a furnace filter, to prevent dust and debris from accumulating.
9. Insulate the Air Handler
If your air handler is located in an unconditioned space, such as an attic, consider insulating it with fiberglass or foam insulation. This will help prevent heat loss and improve the efficiency of your system when it’s operating.
10. Tighten Drain Lines
Check the drain lines for any leaks or cracks. If necessary, tighten the lines or replace them to ensure proper drainage during the winter months.
11. Inspect the Thermostat
Remove the thermostat cover and inspect the batteries. If they are low, replace them with fresh batteries. Reset the thermostat to the “off” position or a low temperature setting to prevent accidental operation.
12. Cover the Outdoor Unit
If your outdoor unit is not enclosed in a protective housing, consider covering it with a tarp or a custom-made cover. This will provide additional protection from snow, ice, and other winter elements.
13. Check Regularly
Throughout the winter, periodically inspect your covered air conditioner to ensure it remains in good condition. Look for any signs of damage, leaks, or excessive snow accumulation. If necessary, make adjustments or repairs to prevent further issues.
Winterizing Your Air Conditioner: Why It’s Important
Winterizing your central air conditioner offers several benefits:
- Protects the unit from harsh weather conditions, such as snow, ice, and extreme temperatures.
- Prevents damage to essential components, such as the compressor and refrigerant lines.
- Extends the lifespan of your air conditioner by reducing wear and tear.
- Maintains the efficiency of your system, ensuring optimal performance when it’s needed.
- Reduces the risk of costly repairs or replacements in the future.
What You Need to Know
1. Can I use a plastic tarp to cover my air conditioner?
Yes, you can use a heavy-duty plastic tarp to cover your air conditioner. However, it’s important to ensure the tarp is securely fastened and provides adequate protection from the elements.
2. Do I need to disconnect the refrigerant lines?
For units with exposed refrigerant lines, it’s recommended to disconnect them and cap the ends. This prevents moisture and debris from entering the system and potentially causing damage.
3. Is it necessary to cover the evaporator coil?
Yes, it’s important to cover the evaporator coil to prevent dust and debris from accumulating. This can reduce the efficiency of your system and lead to premature failure.
4. How often should I inspect my covered air conditioner?
It’s recommended to inspect your covered air conditioner regularly throughout the winter, especially after heavy snow or ice storms. Look for any signs of damage or leaks.
5. Can I leave my air conditioner running all winter?
No, it’s not recommended to leave your air conditioner running all winter. The unit is not designed to operate in freezing temperatures and can lead to damage or reduced efficiency.
