It’s the middle of summer and the last thing you want is for your air conditioner to stop working. There’s nothing worse than being stuck at home or in your office , on a hot summer day wondering “why is my air conditioner not blowing cold air? If your AC unit isn’t working, there are a few possible explanations. In this blog post, we’ll explore some of the most common reasons the cold air might have stopped flowing.

Your Unit Is New
New air conditioner owners often turn it on and wonder why the air isn’t immediately blowing cold. Letting a new AC run for a while is often all that’s needed to start the cold air flowing. However, if it isn’t new and the air isn’t cold, it could be something more serious.
If the thermostat is set to “heat” instead of “cool” you will not receive cold air. This seems like an obvious one, but it’s worth checking just in case.
The Air Filter
A dirty air filter can restrict airflow and prevent your AC from working properly.
The Outdoor Unit Is Blocked
If the airflow around the outdoor unit is restricted, the AC won’t work as efficiently as it should. Leaves and debris are the most common culprits.
The AC Is Too Big Or Too Small For The Room
An air conditioner that’s too big will turn on and off frequently, which can cause moisture problems and make the room feel stuffy. On the other hand, an AC that’s too small will run constantly without ever reaching the desired temperature.
More Serious Problems
The Evaporator Coils Are Frozen
This is usually caused by low refrigerant levels and can be a serious problem. You’ll need to call a professional to fix it.
There’s A Refrigerant Leak
A leak in the refrigerant line can cause all sorts of problems, including water damage and decreased efficiency. Again, this is a job for a professional.
The Ducts Are Leaky
If your ducts aren’t sealed properly, cooled air can escape before it ever reaches your living space. This not only makes your home less comfortable, but it also wastes energy and drives up your utility bills. Call a professional to have it fixed and working again.
The Compressor Isn’t Working Properly
The compressor is responsible for circulating refrigerant through the AC unit, so if it’s not working, the whole system suffers. Compressor problems usually require professional help.
There’s An Electrical Issue
If you’re having trouble with any of the electrical components in your AC unit, shut off the power immediately and call an electrician—attempting to fix electrical problems yourself can be extremely dangerous!
You Have A Thermistor Problem
The thermistor monitors temperature and helps to regulate cooling in the evaporator coils. If it malfunctions, it can prevent cold air from being circulated. This is another issue that will require professional assistance to resolve.
