Step by Step Guide: How to Winterize an Air Conditioner

Step by Step Guide to Winterize an Air Conditioner

Here we have given a step-by-step guide on how to winterize an air conditioner.

Step 1:

Find a level, shaded area to set up your air conditioner in. Lay down the wood on the ground, so it is protecting grass, plants, or soil. Make sure you have enough room, so you do not knock over the wood.

Step 2:

Unbox the window air conditioner and set it up on top of the wood where you have prepared to work. Make sure that there is room between the unit and everything else so that it can vent properly.

Step 3:

Put the cover on top of the unit. This is just a temporary covering so that you can protect it from rain and wind. If you are using a tarp, make sure to use the bungee cords to tie up any loose sides. Heavy-duty zip ties can also be used instead of bungee cords or for an additional form of security operation protection.

Step 4:

Find the cover that was given to you by the manufacturer and put it on your unit. Make sure that it has all of the correct fittings and that there are no holes or spaces.

Step 5:

Once you have put the cover on your unit, take a step back and survey your work to ensure everything is tight and secured correctly. If you have problem areas, retie them with bungee cords or zip ties.

Step 6:

Cover the window air conditioner with a tarp or another waterproof layer. You want to make sure it is completely covered, and there are no tears in the tarp. If you do not have access to twine or cords, then staples and nails can be used as an alternative.

Step 7:

Take everything out of the area where your unit is set up. This will hopefully be a shaded area, but regardless you want to make sure that it is clean and clear. Remove all old wood, rusted nails or staples, anything that can cause damage or injury. Use deck cleaner if necessary to make sure there are no stains left behind.

Step 8:

Store away the unit will all of the parts that you have set up for winter. Make sure that everything is put in its proper place and organized correctly. Check the manual if anything seems confusing or foreign to you; there should be a section on how best to store your air conditioner over the winter months.

Step 9:

Make sure that the unit is turned off and pieces are appropriately locked away before you leave. Do not assume that your regular maintenance will be enough to keep it from catching on fire or causing an electrical surge, even if it seems normal now.

Step 10:

Takedown any temporary coverings. If there is a tarp or other waterproof is the reverse process of assembly, so make sure to put it all back together correctly. If you are unsure, check your manual or manufacturer’s website for more details on what they recommend.

Conclusion:

With the cold weather coming in, it’s essential to winterize your air conditioner. Check out these simple steps above for how to winterize an air conditioner yourself. If it is a window AC, we will need to remove the window from its opening and place a sealant around the edges of the frame. This helps prevent leaks that could lead to mold or mildew buildup inside your home.

For an air conditioning system installed in another area of your house, we’ll want to make sure all ductwork has been appropriately insulated with insulation designed for HVAC systems before sealing up any areas where they pass through walls or ceilings. This includes both supplies and returns vents and ceiling diffusers/grilles near registers on each floor.
