Man Drills Wall and Installs DIY Duct to Cool Two Rooms with One AC Unit

A viral video shows a clever way to cool two rooms with one AC, but it could ruin your system

The DIY hack uses cheap plastic pipes to split cold air through a wall, but experts say it will spike your power bill.

Trying to save money on your power bill can lead to some wild ideas. But some quick fixes end up costing you much more in the long run.

WHAT HAPPENED

A new video online shows a homeowner trying to beat the heat. They attached a white plastic pipe to the front of their wall AC unit.

The pipe goes through the wall to send cold air into the next room. It uses plastic elbow joints to direct the flow.

The video claims this is a smart way to cool two rooms with one machine. Many people online love the creative idea, but experts are warning against it.

FACT BOX

• Uses white PVC pipes and elbow joints
• Connects directly to the AC air outlet
• Sends air through a hole in the wall
• Cuts down on the cost of buying a second AC unit
• Can cause the system to work too hard and break

WHY IT MATTERS

AC units are made to cool a specific amount of space. They need to pull warm air back in to work right.

When you block the air with pipes, the system works too hard. Your power bill goes up, and the machine might break down fast.

WHAT HAPPENS NEXT

More people will likely try these hacks as summer heat rises. We will see if safety groups warn against them.

If you want to cool two rooms, experts still say it is best to get a second unit or use a fan.

WHAT WE STILL DON'T KNOW

1. How much did the parts for this DIY project cost?
2. Did the AC unit break down after running like this?
3. How much did the power bill go up in that house?
