air conditioning in condo is not working
Добавлено: Вт июл 07, 2026 8:31 pm
Condo is in a five story building. The building was built in 2021-2022.
The condo has been unoccupied for more than one year.
Recently, I tried to use the air conditioning. I set the thermostat as follows:
Temperature: 19°C
Mode: Cool
Hold: On
Fan mode: Auto
The fan/blower is working. Air is coming from the vents.
However, the AC is not producing cold air. The unit is not cooling the condo.
The indoor temperature did not go below 24°C.
The condo has a central heat+AC unit.
In the unit, there are the following labels/texts:
```
Climetec model CI-4
This unit is equipped with a Standex-Meder Electronics (StandexMeder.com) condensate overflow shut-off switch installed on the drain pan or drain line. If unit is not operating, lift switch/cap assembly to test. If unit runs, drain needs to cleared. Clean and test every 180 days.
There is also another label from the Builder:
Model 450
Zone Valve: 2 Way ERV
```
Would the "condensate overflow" mentioned in the text be the problem?
