8 Ways On How To Store Portable Air Conditioner Over Fall & Winter

Summer is ending, and it is time to keep the portable air conditioner in the storeroom until the foreseeable future. It protects the air conditioning unit from dust, moisture, and accidental damage resulting in expensive repairs. In this post, we will advise you on the proper way to store an air conditioner and its equipment so you have a 100% working unit when the summer returns. Read on.


Why Should You Store A Portable AC?

We will keep our summer shorts and bathing suits away when transitioning into the winter season. Likewise, it is imperative to store the portable air conditioner in a safe place where you will not touch it for another next eight months. Doing so will ensure the portable AC do not:

  • Lose any vital equipment needed for the air cooling.
  • Collect dust that clogs the air ventilation and reduces the cooling efficiency.
  • Damage the internal components and incur expensive repair costs.
  • Mold growth on the filters and equipment thus reduces the appliance’s lifespan.
  • Energy wastage as a standby AC will still drain electrical power.

Below are some of the best ways to store a portable air conditioner.

1. Carefully Wrap And Store The Power Cord

First, turn off the portable AC and unplug it from the electrical socket. Wrap the power cord carefully for easy storage and prevent it from becoming tangled. You can use the shoulder-wrap, braid-wrap, or our favorite over-under-wrap techniques. Secure the wrapped cord with a tape, loop plastic tag, tag string, hangtag, or rubber band to secure it. If the particular model comes with a power cord storage compartment, fit it inside to reduce tripping risk.

2. Keep It Away From External Elements (Sunlight, Rain, Snow)

It should be common sense that any appliances should not be directly exposed to sun, rain, or snow. Prolonged exposure to the sun UV ray will discolor or turn the plastic housing yellowish. It will also release harmful byproducts and damage the portable AC. The same applies to rain and snow. Instead, place it inside to shield it from harsh elements and extreme temperature.

3. Choose A Non-humid Place To Store The Portable AC

A good place would be an attic, storeroom, basement, or utility room since you will be leaving the portable air conditioner untouched for months. Keep it dry and clean with the dampness level not exceeding 50%, as it will promote mold growth and other harmful pathogens. It will also discourage the habitat of insects, mice, or rodents from chewing on the wire.

4. Clean And Empty The Water Tank

Some portable air conditioners come with a water tank that collects water collected during the cooling and dehumidification. It is vital to keep it dry and clean as it prevents corrosion and mold infestation. Empty the water and wipe away any residues left in the reservoir. Take apart the drain knob and rubber hose to drain any remaining water trapped within. Leave the unit air-dry completely before attempting to store it.

5. Clean Or Replace The Filter

Portable air conditioners come with an air filter that blocks dust, dirt, hair, and other dirty particles from passing through. Cleans the filter by using a toothbrush or vacuum it gently with a brush attachment. For stubborn pollutants, rinse it with some soap and lukewarm water. Leave the filter air dry before attempting to install it back and store the portable AC. Alternatively, discard the old filter and replace it with a brand new one to save you all the trouble.

6. Clean The Portable Air Conditioner

Like the filter, the portable AC must be clean thoroughly to prevent dust buildup. Get a wet cloth and start wiping the exterior, particularly the gaps between ventilation from dust and dirt. You can mix some water with distilled white vinegar to remove stubborn stains. If the internal components are accessible through a removable panel, use a dry cloth and carefully remove any dust. Leave it air dry, inspect the condition, and if everything is sparkling clean, you can put it in the storage room.

7. Pack It Up

If you still have the original box, perfect! Find a similar size box or cover it with a plastic bag if you don’t.
Unscrew any removable parts, vents, or hoses, and keep them aside. Be extra cautious to avoid injuring yourself or damaging the air conditioner. Carefully place each part into the box so you will not misplace them. Lastly, put back the air conditioner inside the box and make sure it is in the upright position. Doing so will prevent unnecessary pressure on the compressor and allows oil to resettle. The goal is to keep dust away from the AC, even in the storeroom.

8. Can’t Store It? Cover It.

If for some reason, you can’t store your portable AC or lack the space to do so, you can find a designated cover to shield it. It is better than leaving it completely exposed. Covering the AC will prevent dust from building up, protect from sunlight damage, and discourage microbes growth. You can find the AC’s cover in any hardware store or use a large blanket.

Final Thoughts

Air conditioners are expensive, even if is a portable unit. To protect its longevity, You will need to keep it in tip-top condition for optimal performance season after season. As per our guide, properly storing an unused AC is a good place to start. Do follow up with regular maintenance and servicing to keep it problem-free. If you are sick of storing the portable AC year in, year out, maybe it is time to invest in a central air conditioner with a better cooling efficiency.
