Portable air conditioner not cooling attic.
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.
Next please only consider two hose portable ac units.
Portable air conditioners send as much moisture out with the exhaust air as they can.
Usually it ll take 60 90 seconds after you power up the unit.
The more leaks your air ducts have the less cool air your home gets.
So any ac you buy will blow moisture up into your attic.
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.
This prevents air flow.
When water doesn t drain properly from a portable air conditioner it builds up and can freeze around the coils.
Limited or lack of air flow can often be the result of a dirty or clogged filter.
Examine the exhaust hose and check if there is any obstruction here.
Portable air conditioners do need to be vented to pump the hot air outside.
Another reason your portable air conditioner may lack air flow is the presence of frost on the evaporator coils.
Then check for any air intake obstacles and eliminate them.
Unfortunately units love to act up on the hottest days of the year.
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.
Air ducts with leaks allow conditioned air to escape into unconditioned areas i e.
In turn no matter how long you run the ac you still feel clammy.
They are designed this way to minimize how often you have to empty the catch bucket.
For one most traditional room air conditioners are not capable enough to handle the extreme heat that s normally present in an attic.
The catch bucket is only there for the excess.
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.
At least troubleshooting common portable air conditioner issues might be less of a hassle than you think.
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.
If it is clean it.
This is true even if you have covered all the bases including correct unit sizing and proper insulation.
It s a standalone unit that s about two feet tall and 18 inches wide and has wheels for mobility.
Most come with a window kit for this purpose that attaches to a hose on the back of the unit.
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.
Lack of airflow coming out of the air conditioner.
