- Change your filters. Dirty filters reduce the air flow across your evaporator coils. When not enough air is flowing through the evaporator, the refrigerant is not properly heated up (your air gets cooled) and the refrigerant may stay so cold that it begins to freeze up the evaporator coil.
- Check if the outside fan and compressor is running. If the outside fan is not running the indoor heat is not being removed from the refrigerant and your house stays warm. If the compressor isn’t working, then the system is not circulating the refrigerant which is what carries the heat from inside your home to the outside.
- Check to make sure nothing is blocking the vents and returns. Similar to changing the filters, blocking the vents or returns can reduce the air flow through the evaporator coil preventing the refrigerant from chilling the indoor air.
If you have gone through these steps and find that your air conditioning unit is still not cooling your home, contact us at Air Quality Control. When you call, it will be helpful that you share with us the diagnostic steps you have taken. This will help to better determine what it may be, and for sure what it is not which will prepare us when we come to your home.
