A sliding door is the easiest way to ventilate your portable AC because it’s the same as installing it through a window when it comes down to it. Many hardware stores sell kits specifically tailored for sliding doors, which provide a tight seal.
First, assemble and measure the vent panel.
Apply the weather strips to the door frame.
Attach the exhaust hose from the air conditioner to the panel.
You’ll need to be comfortable drilling a hole into one of your walls for this method. If you don’t feel like you have the skills for this method, call a technician.
Once you’ve identified a spot on the wall to put the vent hose, you must measure the diameter and use a saw to cut the hole through to the outside.
Next, pass the exhaust hose through the wall vent and install the panel on the outside of the house.
Use silicone caulk to seal any opening around the hose and vent both indoors and out.
This method is best if your home has a drop ceiling.
Create an opening in a ceiling panel by measuring the diameter of your exhaust vent hose.
Pass it through the ceiling panel and secure it.
Then, seal the area around the hose with silicone caulk.
Before drilling into your wall, check for studs and any electrical wiring. Drilling through studs can weaken the house’s structure, and drilling through wires can cause electrocution.
