The situation when the air conditioner is not cooling relates to all not properly maintenanced air conditioners. The first thing to do is to check the settings on the remote control. Press the “MODE” button to select the “COOL” mode and set the temperature below ambient. Increase the fan speed by several clicks on the “FAN” button. Make sure that the outdoor unit is working. The second is to clean the filter. Replacing the filter is an important task because it means that your air conditioner can work as intended, without any unnecessary stress from trying to push air through dirt and debris. It’s a simple task as a homeowner and should be done every month or so depending on how frequently you use your unit.
- Find your air filter. It can be in the furnace, the air conditioner or the return duct.
- Turn off power to your unit before you remove the filter.
- Take the filter out. From there, you can clean it or choose to replace it.
- Replace the filter and take care to ensure that the arrows indicating airflow match up with how air is blowing through your system.
- Put the panel back and close your unit. Turn the power on.
If the air conditioner blows warm air after the above operations, then you can confidently call the HVAC repair assistant. In standard cases, it takes from twenty minutes to one and a half hours to diagnose and eliminate a malfunction - this is 80% of all calls. Standard repairs include filling with freon and replacing the starting capacitor. Still, the technician may investigate some more issues which require a more serious repair. If you’re not able to get the problem resolved with the above troubleshooting tips, have an experienced HVAC professional investigate further to identify the cause. Even if you are successful, it may be wise to upgrade from an older thermostat to a new programmable model, to avert future problems.
