If your air conditioner isn't working, it could be due to several reasons. Common causes include dirty or blocked air filters, problems with the compressor or refrigerant, loose, damaged, or burned disconnection cables, and clogged air filters. All of these issues can result in the air conditioner not blowing air, not turning on, or simply not appearing to work properly. As an expert in air conditioning systems, I recommend taking the following steps when your system is not working properly.
Check Your Electrical PanelThe first step is to check your electrical panel to see if it has a switch triggered.
Then, confirm that the thermostat is turned on.
Check the Air FilterAfter that, check if the air filter is clogged and that the condensate pump is working properly. If the filter is dirty or clogged, it can block the flow of cold air into the house and cause the air conditioning system to expel hot air or shut off completely. Additionally, a clogged filter can cause the air conditioner coils to freeze, affecting the compressor and thus restricting air flow to the unit.
Check for Warm AirIf you see warm air instead of cold air coming out of the vents, this could indicate that the filter is clogged or that the coils have dirt or ice accumulated around them. The indoor fan draws hot air into the air conditioning unit, and if it is dirty, it will not be able to bring in enough air to cool the house.
Check Refrigerant LevelsIf your home's refrigeration unit is running but no cold air is coming out of it (or if it takes longer to cool down), the air conditioner refrigerant may need to be charged.
If the air conditioner doesn't cool, but you feel that little air is coming out of the vents, there may be a problem with airflow.
Check for Ice BuildupThe most likely reason your central air unit will freeze is because the air filter is clogged or dirty. The tempting but risky approach would be to simply replace the filter and see if the ice melts off the coils naturally. For more information on how to troubleshoot your air conditioner, don't hesitate to contact Morris Plumbing, Heating & Air Conditioning at (97) 961-0338. If you have a traditional air conditioning unit, they can tell you what size filter is right for your system.
Clean or Replace Filters RegularlyThe air conditioning system uses refrigerant to extract heat from inside of the house and release it outside. It's important to regularly clean or replace your home's filters in order to keep your system running smoothly and efficiently.
If you follow these steps and still experience problems with your air conditioning system, contact a professional for help.
