If you find your air conditioner is not cooling, here are some of the first steps you can take to see
if it is possibly just a simple DIY project, or if you need to call an experienced HVAC technician
to come and repair your air conditioner.
1. 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
2. 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.
3. Check to make sure nothing is blocking the vents and returns. Like 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. Give us a call. When you call the technician, it will be helpful that you share with
them the diagnostic steps you have taken. This will help them to better determine what it may be,
and for sure what it is not which will prepare them when they come to your home.
