Hello,
are you confident that it was stored in a manner that a nest could not be built in front of a coil?
I service many where the culprit is "seasonal damage"

This is an indoor air conditioner and stored inside. We only used it a couple of times last year before removing and storing and it worked fine when we put it away.

Thank you...you have very few options if the compressor is indeed running..
1 - the lost its refrigerant..compressor is running but the unit has no freon
2 - oil trap...tilted, stood on side or rear...this makes oil from compressor flow into the piping and creates a blockage.
3 - compressor is running but internally is not pumping.
So if the fan runs and compressor runs...the above items are the only choices.
If compressor did NOT run it would be a different list.

So how do I go about determining what you're suggesting is the problem. Or, otherwise, what's the fix?Jack
Expert:  BillyHvac replied 1 year ago.
This depends on ones skill set and comfort level.
The unit would be removed and covers removed...then plugged in to bench test.
Then gages would be hooked to unit and the pressure checked to see if unit is pumping but there is nothing to pump....or the compressor "runs" but mechanically is not moving refrigerant.
Generally this must be done by an EPA certified repair shop.

I'd like to try and recharge it myself and need to know if you can guide me through the steps?
