My trane heat pump inside unit leaks water during the most hot and humid part of summer ever since it and a new outside unit was installed in 2009.
Ac unit leaking water outside.
Condensation is then produced on the coils of the unit which is supposed to go down the drain pan and lines.
A clogged condensate drain line is the most common cause of water leaking from your ac into your home.
When the weather outside changes it can affect the ac unit and when it starts to get to cold out it can cause excess water too.
If the pool of water is small it could be normal and may not require anything.
And if you don t know water is produced by all ac units when warm air coming inside the unit interacts with the evaporator coil whose function is to cool that air down.
In that case you ll need to unclog it.
Unfortunately this can get blocked and can result in leaks.
Once the temperature outside goes up it should dry up.
More water means it will overflow and collect and because it s not as hot out it takes longer to dry up.
When it comes to air conditioners there are a number of other reasons why water is leaking inside your home.
Heat pumps should be raised up off the pad to allow for drainage.
When your unit attempts to cool your home down when temperatures outside are under 60 degrees the coils could freeze up causing the unit to leak water.
In fact seeing a puddle by the air conditioner s primary drain is the most common reason you might believe it is leaking however this is not only normal but actually a sign that your air conditioner is working.
If those coils freeze your drain pan may overflow and leak water.
Excess water can be a symptom of a blocked outdoor coil.
Clogged drain line every air conditioner has a drain line for water to pass through until it reaches the drain.
Check the back of your air conditioning unit for a buildup of dirt and or debris.
Again it depends on temperature and humidity.
Causes of water leaks from air conditioners air conditioners are designed to drain the water they collect.
If the drain line gets clogged with dust dirt sludge or mold that water backs up into your home.
The bottom pan in the outside heat pump unit has drain holes that need to be kept clear for proper drainage.
Water from the outdoor air conditioning unit can be drained away with a drain kit or drain pan.
Leaks happen when this path is not followed.
There are multiple unclogging methods like using a wet dry vac on the condensate line.
