Next please only consider two hose portable ac units.
Portable air conditioner not cooling attic.
Limited or lack of air flow can often be the result of a dirty or clogged filter.
For one most traditional room air conditioners are not capable enough to handle the extreme heat that s normally present in an attic.
Another reason your portable air conditioner may lack air flow is the presence of frost on the evaporator coils.
Similar to the previous problem mentioned to find the problem of this portable ac not cooling adequately see the filter and check if it is clogged or dirty.
They are designed this way to minimize how often you have to empty the catch bucket.
Unfortunately units love to act up on the hottest days of the year.
The more leaks your air ducts have the less cool air your home gets.
Check the temperature of air flowing out of the top of the unit and the air flowing into the evaporator coil behind the top filter grill at the back.
Usually it ll take 60 90 seconds after you power up the unit.
The catch bucket is only there for the excess.
At least troubleshooting common portable air conditioner issues might be less of a hassle than you think.
In turn no matter how long you run the ac you still feel clammy.
Most come with a window kit for this purpose that attaches to a hose on the back of the unit.
It s a standalone unit that s about two feet tall and 18 inches wide and has wheels for mobility.
A portable air conditioner is the easiest solution for cooling your attic.
Lack of airflow coming out of the air conditioner.
Portable air conditioners send as much moisture out with the exhaust air as they can.
Use a vacuum or brush.
This is true even if you have covered all the bases including correct unit sizing and proper insulation.
When troubleshooting this portable air conditioner problem first clean the filter to get rid of any dust or dirt that has been trapped inside it.
After you ve made sure that the mode is set for cooling not the dry or fan setting wait for the compressor to kick on.
If it is clean it.
So if there are leaks along the ductwork that allow cold air to escape into the attic or basement your home won t get as much cool air as it needs to reach your set temperature.
So any ac you buy will blow moisture up into your attic.
Then check for any air intake obstacles and eliminate them.
Portable air conditioners do need to be vented to pump the hot air outside.
Examine the exhaust hose and check if there is any obstruction here.
When water doesn t drain properly from a portable air conditioner it builds up and can freeze around the coils.
Any leak on the return side of the ducts would mean that your air conditioner is sucking in the hot and humid air from the attic.
Air ducts with leaks allow conditioned air to escape into unconditioned areas i e.
