We will also cover when it makes sense to remove versus winterize your unit, helping you make the best decision for your specific situation.
Why You Should Remove Your Window AC Unit
Removing your window air conditioner at the end of cooling season provides several important benefits that many homeowners overlook. Cold drafts entering through and around the unit can increase your heating bills by 10-15% during winter months, costing you hundreds of dollars in wasted energy. Gaps in weatherstripping, poorly sealed accordion panels, and the unit itself all create pathways for cold air to enter your home.
Winter weather can damage your air conditioner if left installed year-round. Snow, ice, and freezing temperatures can corrode the condenser coils, damage the fan motor, and cause refrigerant leaks that require expensive repairs. Even units marketed as “all-weather” or “winter-ready” benefit from indoor storage during harsh conditions.
Removal also gives you the perfect opportunity to perform deep cleaning and maintenance that keeps your unit running efficiently. Accessing the condenser coils, evaporator fins, and internal components is much easier when the unit is out of the window. Regular cleaning can improve efficiency by up to 15% and extend the lifespan of your air conditioner by several years.
Tools and Materials You’ll Need
Before you begin the removal process, gather all necessary tools and materials to avoid interruptions. Having everything on hand will make the job safer and more efficient.
- Screwdriver set – Phillips and flathead drivers to handle different screw types on mounting brackets and the unit itself.
- Power drill with bits – Some installations use screws that are easier to remove with a drill, especially if they are rusted or over-tightened.
- Work gloves – Heavy-duty gloves protect your hands from sharp metal edges, screws, and the unit’s weight.
- Helper or second person – For units over 80 pounds, having assistance prevents accidents and makes lifting much safer.
- Towels and drop cloths – Place these underneath the unit to catch water drips from the condensation pan and protect your floors.
- Cleaning supplies – Mild detergent, warm water, soft brush, and clean rags for post-removal cleaning.
- Plastic storage cover – A fitted cover or heavy-duty plastic sheet protects the unit during storage.
- Ziplock bags – Store screws and small hardware to prevent loss.
Do not forget to wear closed-toe shoes with good traction. Window AC units are awkward to handle, and you need stable footing throughout the process.
How to Remove a Window Air Conditioner: Step-by-Step
This section walks you through the complete process of removing your window air conditioner safely and efficiently. Follow each step carefully, and never skip safety precautions.
Step 1: Power Off and Unplug the Unit
Always start by turning off the air conditioner using the control panel or remote. Allow the unit to run for a few minutes in fan-only mode if available, which helps dry out internal components and reduces mold risk during storage. Once the unit is completely off, unplug it from the electrical outlet.
Never attempt to remove a window AC while it is plugged in. Even with the unit off, electrical connections pose a shock hazard, especially if condensation has leaked onto the plug or outlet. If your unit is hardwired or connected through a dedicated circuit, turn off the breaker at your electrical panel before proceeding.
Step 2: Remove the Front Cover and Filter
Most window AC units have a front cover that snaps or slides off the main body. Check your owner manual for specific instructions, but generally, you can release the cover by pressing tabs on the sides or bottom. Set the cover aside in a safe location where it will not get stepped on or damaged.
Remove the air filter next. Most filters slide out from the front or side of the unit. If your filter is washable, set it aside for cleaning. If it is disposable, note the size and type so you can purchase a replacement before next season. A clogged filter reduces efficiency by up to 20%, so this is an important maintenance step.
Step 3: Locate and Remove All Screws and Fasteners
This is where many removal attempts go wrong. Window AC units typically have multiple screws securing them to the window frame, and missing even one can make removal impossible or damage your window.
Check these common screw locations:
- Window sill screws – Usually 2 screws through the bottom frame of the AC into the window sill
- Side jamb screws – 1-2 screws on each side securing the unit to the window frame
- Louver screws – Screws holding the front louvers or vents in place
- Top mounting bracket – Some units have a bracket screwed into the upper window frame
Use your ziplock bags to organize screws by location. Label each bag if needed. This organization makes reinstallation much easier next season.
Step 4: Remove Side Curtains and Accordion Panels
The accordion-style side panels that fill the gap between your unit and the window frame need removal next. These typically slide into tracks on the sides of the air conditioner. Some models have screws holding the panels in place, while others simply pull out.
Extend each panel fully, then lift up and out of the track. Be careful, as these panels can be sharp along the edges. If the panels are stuck due to dirt or rust, gently tap them with a rubber mallet to loosen, or use a lubricating spray on the tracks.
Step 5: Remove Weatherstripping and Seals
Peel away any foam weatherstripping, sealing tape, or caulk that was applied around the unit. Some homeowners use temporary foam strips that compress between the unit and window frame. Remove these carefully to avoid damaging painted surfaces.
If you used permanent caulk or adhesive during installation, you may need a putty knife to carefully separate the seal. Work slowly to avoid chipping window paint or damaging wood frames. Any damage here can lead to air leaks when you reinstall the unit.
Step 6: Prepare for Lifting
Before lifting the unit, place towels and a drop cloth directly beneath the window. Window AC units always have some water in the condensation pan, and this will drain out when you tilt the unit. The towels prevent water damage to your floors and walls.
Open the window sash fully if possible. This gives you more clearance for removing the unit and reduces the risk of the unit catching on the window frame during removal. If your window has a security lock or stop that prevents full opening, remove these first.
Step 7: Carefully Lift and Remove the Unit
This is the most physically demanding part of the process. Window AC units are heavy, bulky, and awkward to handle. Refer to the weight guide below to understand if you need help.
Weight Guide by BTU Capacity:
- 5,000-6,000 BTU – 40-50 lbs (suitable for one strong person)
- 8,000-10,000 BTU – 65-80 lbs (two people recommended)
- 12,000-15,000 BTU – 85-110 lbs (two people required)
- 18,000+ BTU – 120+ lbs (two people and lifting straps recommended)
Grasp the unit firmly with both hands, keeping your back straight and lifting with your legs. Tilt the unit slightly backward to drain any remaining water. If working with a helper, coordinate your movements and establish clear communication before lifting.
Lift the unit up and back into the room, not outward through the window. This prevents accidents if the unit slips. Place it gently on the floor, keeping it upright. Never lay a window AC on its side or back, as this can damage the compressor and cause refrigerant leaks.
After removal, consider whether a portable air conditioner might better suit your needs for future cooling seasons.
Step 8: Close and Secure the Window
With the unit removed, lower the window sash completely and engage the locks. Check that the window closes properly and seals tightly. If you notice drafts or gaps, apply temporary weatherstripping or consider permanent solutions like new seals or storm windows.
Store the accordion panels and any mounting hardware in a labeled bag or container. Keep these with the air conditioner so everything is together when reinstalling next season.
Cleaning and Preparing for Storage
Proper cleaning before storage prevents mold growth, maintains efficiency, and extends your unit’s lifespan. Take time to do this thoroughly while the unit is accessible.
Clean or Replace the Filter
Wash reusable filters in warm water with mild detergent. Rinse thoroughly and allow to air dry completely before storage. Do not reinstall a wet filter, as this causes mold and mildew. If your filter is disposable and visibly dirty, replace it.
Clean Condenser and Evaporator Coils
Use a soft brush or vacuum with brush attachment to remove dust from the coils. The condenser coils (usually at the back) and evaporator coils (inside near the filter) both need attention. For deep cleaning, you can use a foaming coil cleaner available at hardware stores, following product instructions carefully.
Empty and Clean the Condensation Pan
Locate the condensation pan at the bottom of the unit. Pour out any remaining water and wipe the pan with a clean cloth. Use a mild bleach solution (1 part bleach to 10 parts water) to kill any mold or algae that may have formed. This prevents odors and maintains healthy air quality next season.
Storage Location and Positioning
Store your window AC in a cool, dry place like a basement, garage, or closet. The unit must remain upright at all times. Laying it on its side can cause compressor damage and refrigerant leaks that require professional repair.
Keep the unit away from direct sunlight, excessive moisture, and extreme temperatures. Cover it with a breathable storage cover or sheet to prevent dust accumulation while allowing air circulation.
Troubleshooting Common Removal Problems
Even with proper preparation, you may encounter difficulties when removing your window air conditioner. Here are solutions to the most common problems our readers face.
The Unit Is Stuck and Won’t Move
If your AC will not budge after removing all visible screws, check for hidden fasteners. Some installers add screws through the side curtains into the window frame, or through the bottom rail into the sill. Use a flashlight to inspect all surfaces carefully.
Older units may have paint or caulk sealing them in place. Gently tap the sides with a rubber mallet to break the seal, or carefully cut along the edges with a putty knife. Work slowly to avoid damaging the unit or window frame.
Dealing with Stripped Screws
Stripped screws are frustrating but manageable. Try placing a rubber band over the screw head before inserting your screwdriver, which can provide enough grip to turn the screw. If that fails, use screw extraction pliers or a screw extractor kit from your hardware store.
As a last resort, you can drill out the screw head using a drill bit slightly larger than the screw shaft. Be extremely careful not to drill into the window frame or AC unit itself.
Units Without Visible Mounting Screws
Some installations rely on friction and the weight of the unit rather than screws, particularly in double-hung windows with the sash lowered onto the top of the unit. In these cases, the unit may simply lift out once the side panels are removed.
Other units use a mounting sleeve that stays in the window while the AC chassis slides out. Look for release tabs or screws that allow the inner unit to slide forward and out of the sleeve.
Winterizing vs Removing: Which Is Right for You?
In some situations, completely removing your window air conditioner may not be practical or necessary. Understanding when to winterize instead can save time while still protecting your home and unit.
When to Remove:
- You have storage space available
- The unit is easily accessible
- You want maximum energy efficiency
- The unit needs deep cleaning or repair
- Your winters are particularly harsh
When to Winterize:
- You live in a mild climate with minimal freezing
- The unit is very heavy or difficult to access
- You lack appropriate storage space
- The installation is permanent or semi-permanent
- Removing it risks damaging the window
To winterize properly, remove the front cover and filter, clean thoroughly, and install an insulated AC cover both inside and outside. Seal all gaps with weatherstripping and consider adding a window insulation kit over the entire installation.
For homeowners considering a more permanent solution, a energy-efficient heat pump or ductless mini-split system provides year-round climate control without seasonal removal.
Disposal and Recycling Options
When your window air conditioner reaches the end of its useful life, proper disposal is essential. AC units contain refrigerants that are regulated by federal law and cannot simply be thrown in the trash.
Contact your local waste management authority to find appliance recycling programs in your area. Many municipalities offer seasonal collection events for appliances containing refrigerants. Some retailers, including major home improvement stores, offer haul-away and recycling services when you purchase a new unit.
Scrap metal dealers may accept AC units, but verify they are certified to handle refrigerant removal first. Improper disposal carries fines and harms the environment. Some utility companies even offer rebates for recycling old inefficient units when upgrading to Energy Star models.
If you are considering an upgrade, central air conditioning systems offer whole-home comfort without the seasonal hassle of window units.
How to take out a window AC by yourself?
You can remove a smaller window AC unit (under 60 lbs) by yourself with proper technique. Always unplug first, remove all screws and fasteners, place towels below to catch water, and lift with your legs keeping your back straight. For units over 80 lbs, always have a helper to prevent injury and damage.
Can you remove window AC units?
Yes, window AC units are designed for seasonal removal. The process involves unplugging the unit, removing mounting screws and fasteners, detaching side panels and weatherstripping, then carefully lifting the unit out of the window. Most homeowners can complete this task in 30-60 minutes with basic tools.
How heavy is a window air conditioner?
Window air conditioners typically weigh between 40 and 120 pounds depending on BTU capacity. Small 5,000-6,000 BTU units weigh 40-50 lbs, mid-size 8,000-10,000 BTU units weigh 65-80 lbs, and large 12,000+ BTU units can exceed 100 lbs. Always check your specific model’s weight and get help for units over 80 lbs.
Can I leave my window AC in during winter?
You can leave a window AC installed during winter, but it is not recommended for energy efficiency. Cold drafts enter around the unit, increasing heating bills by 10-15%. If you must leave it, install an insulated cover both inside and outside, and seal all gaps with weatherstripping to minimize heat loss.
Where should I store my window AC?
Store your window AC in a cool, dry place like a basement, garage, or closet. Always keep the unit upright to prevent compressor damage. Cover it with a breathable cover or sheet to prevent dust accumulation. Avoid areas with direct sunlight, excessive moisture, or extreme temperature fluctuations.
How do I clean my window AC before storage?
Clean or replace the air filter, wipe down condenser and evaporator coils with a soft brush, empty and disinfect the condensation pan with a mild bleach solution, and wipe down all exterior surfaces. Allow all components to dry completely before covering and storing to prevent mold and mildew growth.
