Running your unit on AC on fan mode completely dries out the unit on the inside. It is a necessary step before taking on the thorough cleaning. The process should take about two hours.

Removing the filter, dust, and any other impurities
The air filters gather dust and loose dirt as they run. You will need to remove the filter from its frame and shake out any dust. This trick works for AC units with the HEPA and carbon filter types. Sometimes, you might need to replace the filters. Read the manufacturer’s instructions on cleaning and maintaining the filters.

Thoroughly rinse the filter
Use plenty of water to rinse your filters to remove any dirt or dust that might be present. A solution of warm water and mild detergent will work fine as a cleaning solution. Give the air filter time to dry as you clean the rest of the units.

Vacuuming the air intake vents
A hose attachment or hand held vacuum is perfect for cleaning the intake vents. Pay attention not to touch anything that will cause any harm or damage to you during the cleaning process.

Cleaning the cooling coils
The cooling coils need a string acidic solution for a thorough cleaning. A simple acidic cleaning solution works well when sprayed directly to the cooling coils. Some homemade acidic cleaning solutions include lemon/lime juice, vinegar and water. Let it settle for a few minutes after cleaning the coils before returning the filters.

Cleaning the external housing units
The external housing unit of your portable cooling unit gathers dust over time. Luckily, a simple wipe from a damp cloth clears the mess. It is not advisable to use any abrasive or strong chemical solutions while cleaning. A simple solution of mild detergent and warm water will work fine.

Storing till the next season
If the AC unit does not have an in-built heater option, store it until the next season. If possible, return it original packaging, store in a cool dry place away from direct sunlight or moisture.

What to Look For In Portable AC Units

Do you want a remote controlled AC or the digital one? Do you want with an in-built heater, dehumidifier, or air purifier? For starters, it all boils down to individual preferences. There are so many other factors to consider besides comfort and costs.

The majority of the people and homeowners may not be aware of the British Thermal Units standards and ratings on air conditioning units. For instance, heavy duty cooling units need a higher cooling capacity. It is important to look out for the BTU ratings before making a purchase. Establish if it meets the requirements of the intended space. If it does not, it might not be as effective as intended.

A 7,500 BTU unit will work perfectly in a 1,200 cubic feet or 150 square feet room while a 13,000 BTU unit is ideal for 450 square feet or 3,600 cubic feet.

Exceptions
Sometimes, the specifications might not be very accurate given factors such as humidity and the ceiling level.
Another challenge is the number of appliances in a room and how much heat they generate. For instance, some garage appliances might emit too much heat which interferes with the efficient cooling of the unit.
Lastly, the room might not be properly insulated thereby reducing the efficiency of the cooling unit.

Paying Attention to the Warnings
