Is your air conditioning not blowing cold air? Air conditioners can be very finnicky, and often require a bit of maintenance in order to keep them running at their best. In this article, we will discuss the five most common reasons your air conditioning unit might not be blowing cold air. We’ll also provide some tips on how to fix the issue yourself, as well as how to find a reliable repair technician if you need help.
#1: A/C Evaporator Coils Have Frozen Over
Where to look: The evaporator coils are located inside the air conditioner unit.
What to do: If you notice that the evaporator coils have frozen over, you’ll need to thaw them out before the unit will start working properly again. This can be done by turning off the air conditioner and letting it sit for a few hours, or by using a hairdryer on low heat to thaw the coils.
How to prevent it: To prevent your evaporator coils from freezing over, make sure that the air filter is clean and unobstructed. A clogged filter can restrict airflow and cause the coils to freeze.
#2 The A/C Unit’s Refrigerant Line Is Leaking
Another common reason for a non-working air conditioner is a refrigerant line leak. When the refrigerant line leaks, it prevents the unit from being able to cool the air properly.
Where to look: The refrigerant line is located inside the air conditioner unit.
What to do: If you notice that the refrigerant line is leaking, you’ll need to have it repaired by a qualified technician. This is not a repair that can be done by a novice.
How to prevent it: To prevent your refrigerant line from leaking, make sure that it is regularly inspected and maintained by a qualified technician.

#3 Dirty Condenser Coils Are Wearing Out Your Unit
The condenser coils are responsible for releasing the heat that is pulled from inside your home. If these coils become dirty, it can cause the air conditioner to work harder than necessary and shorten its lifespan.
Where to look: The condenser coils are located inside the air conditioner unit.
What to do: If you notice that the condenser coils are dirty, you’ll need to clean them with a brush or cloth. You should be able to find a cleaning solution at your local hardware store.
How to prevent it: To prevent your condenser coils from becoming dirty, make sure that they are regularly cleaned according to the manufacturer’s instructions.
#4 A/C Condenser Fan Isn’t Spinning
The condenser fan is responsible for circulating air over the coils. If the fan isn’t spinning, it can cause the coils to overheat and prevent the unit from cooling properly.
Where to look: The condenser fan is located inside the air conditioner unit.
What to do: If you notice that the condenser fan isn’t spinning, you’ll need to check the wiring to make sure that it’s not loose or damaged. You may also need to replace the fan motor if it’s defective.
How to prevent it: To prevent your condenser fan from malfunctioning, make sure that it is regularly inspected and maintained by a qualified technician.
#5 Air Conditioner Is Not Sized Properly for the Room
If your air conditioner is not sized properly for the room, it will have to work harder to cool the space and may not be able to keep up.
Where to look: The size of your air conditioner is determined by the square footage of the room.
What to do: If you notice that your air conditioner is not sized properly for the room, you’ll need to get a new unit that is appropriately sized. This is something that should be done by a qualified technician.
How to prevent it: To prevent your air conditioner from being improperly sized, make sure that you consult with a qualified technician when choosing a new unit.
When it comes to your air conditioner, there are a few common reasons why it may not be blowing cold air. These include a frozen evaporator coil, a refrigerant line leak, dirty condenser coils, and a condenser fan that isn’t spinning. If you’re having trouble with your air conditioner, make sure to check for these common issues first.
