A portable AC can be a great way to keep cool when your home or work air conditioner is not working correctly. These units are easy to use and can be moved from room to room, making them a cost-efficient option for cooling. However, you can do a few things to improve the cooling power of your portable AC rental unit. Here are some of them:

Keep the Exhaust as Straight as You Can

One of the main things that you can do to improve the cooling power of your portable AC unit is to keep the exhaust as straight as you can. This will help to ensure that the unit can vent the hot air out of the room as effectively as possible.

Ensure All Doors and Windows Are Closed

If you want a portable AC unit you rented to work at its best, make sure all doors and windows in the room are closed. This will help prevent warm air from outside from coming in and will also help keep the cool air inside the room.

In addition, you can also try using a fan to help circulate the air and improve the cooling power of your portable AC unit. Just be sure that you point the fan in the right direction so that it blows the cool air towards you and not away from you.

Turn Off the AC If You Don’t Need It

This may seem like a no-brainer, but it’s worth repeating. If you don’t need the air conditioner, turn it off! Not only can this help significantly lower your energy bill, but it will also prolong the life of your AC unit.

Keep the Air Filter Clean

The air filter is one of the most important parts of any air conditioner. A dirty air filter can impede air flow and reduce the efficiency of your AC unit. Be sure to check and clean the air filter regularly.

Keep the Area around the AC Unit Clear

Another way to ensure optimal airflow is to keep the area around the AC unit clear. This means no furniture, curtains, or other obstructions should b

Turn Off Any Unnecessary Heat Sources

One of the most effective means to improve the cooling power of your portable AC unit is to turn off any unnecessary heat sources in your home. This includes turning off lights (which generate heat), unplugging appliances that aren’t in use, and closing blinds or curtains to keep out the sun’s heat.

If your house has a fireplace, you may consider closing the damper to prevent heat from coming in.

Choose the Perfect Location for the AC

It is important to choose the perfect location for your portable air conditioner. If the unit is placed in a corner, it will not be able to cool the room evenly. The best place for the unit is in the middle of the room, away from any walls.
